Issues When Updating or Installing Killer Control Center

 

Issues When Updating or Installing Killer Control Center

Users may encounter errors when installing or updating the Killer Control Center. 

If you encounter any problems, please select from the following options:

 

 

The Killer Control Center Cannot Automatically Update

 If the installer cannot automatically update, you might see an error, such as, but not limited to, this one:

Killer Performance Driver Suite Cannot Be Installed With

In this case, you will need to manually uninstall the previous versions. First, however, you will want to download the latest installer and have it handy. Once you have the installer ready to go, right-click Start, click Apps and Features, then find every entry that has "Killer" in it, including "Killer Drivers" and/or "Killer Performance Suite, or any variation, and uninstall them. After they have uninstalled, restart your machine, then install the latest suite.

 

Previous Killer Applications or Drivers Cannot Be Uninstalled
OR
There Are No Killer Applications or Drivers in The Apps and Features Menu But the Killer Control Center Will Not Install

If you encounter an issue where the old "Killer Suite" or "Killer Drivers" cannot be uninstalled, and they remain stuck in your Apps and Features menu, or they appear to be removed, but the latest Killer Control Center appears to attempt to install, then roll back, then there are a few ways to address this. Even if you can no longer see the old applications in your Apps and Features menu, it is very likely that they are still there, and that they are the problem. For very old previous installs, especially those that may be broken by updates from Windows 7 to Windows 10, we have developed a tool that can remove the old installs. Here is a step-by-step guide on downloading and using the tool. Use this as your first step in troubleshooting a broken older install:

  1. Download the Killer Remover from here - http://www.killernetworking.com/support/KillerRemover_v1.0.0.1.exe
  2. Right-click Start and click Apps and Features.
  3. Uninstall all "Killer" suites and drivers that will uninstall from this menu. 
  4. Close the Apps and Features menu and double-click the Killer Remover.
  5. Once it is finished, it will prompt you to restart your machine. Restart your machine, and check to see if the stuck item is removed from the Apps and Features menu

 

The Application is Still Stuck or The Latest Package Still Cannot Install After I Have Run the Killer Remover

The Microsoft Installer is probably encountering an error from which it cannot recover. Sometimes, you will get an error, such as "The feature you are trying to use is on a network resource that is unavailable..." or some other seemingly unrelated error, or the installer may fail with no error given other than it could not complete. Luckily, Microsoft has a tool to fix this issue, and you can find our detailed, step-by-step guide on how to find and use Microsoft's tool for fixing problems that block programs from being installed or removed- http://www.killernetworking.com/driver-downloads/kb/faq/34-error-2753-xtendsoftapservice. Make sure you choose "Uninstalling" even if you are trying to ultimately install the latest suite, as the problem is that you need to remove the remaining parts of the old software, even if they do not appear in  your Apps and Features menu. 

If you still have issues with the Killer Control Center's installer, or uninstalling older versions of the suites, please contact support, and we will be happy to help. If the installer is failing, please run the installer one more time, and include the log that is generated in your temp folder. You can access your temp folder by pressing Windows Key + R, typing %TEMP%...

 

winkey r temp

...and pressing Enter.

From there, sort by Date, and attach the most recent MSI***.LOG to your support request. It should be dated at the time you last ran the installer.

Bluetooth or Wi-Fi Missing From Device Manager or Grayed Out

5.0 

Bluetooth or Wi-Fi Missing From Device Manager or Grayed Out

Note: This guide can be used in the event of any M.2 device vanishing from the Device Manager. The procedure lists Killer devices specifically, but the phenomenon is widespread among M.2 devices and Windows 10, and these same steps can be used to restore functionality when any M.2 device disappears from Device Manager.

When this occurs, it is an issue of the BIOS or the operating system not enumerating the device properly. In very rare situations, it can be cause by some kind of physical trauma causing the device to become dislodged, or the device failing, but more often than not, the hardware is just fine. It’s just a matter of getting Windows or, sometimes, the BIOS, to see it again. Sometimes the device will be missing altogether, or sometimes it will be grayed out - the difference is only in whether your Device Manager is set to show devices that are no longer present in the machine. Either way, the Device Manager thinks that the device is gone, and that is what needs to be addressed.

  • First off, make sure that you do not have any USB devices disabled. The internal Wi-Fi and Bluetooth adapter is actually USB device, so if there are any USB devices disabled in your Device Manager, for any reason, this can cause the Bluetooth device to vanish. If you are unable to enable the USB device, then you should resolve that issue first. This includes USB Hub devices, or any devices under the Universal Serial Bus controllers category in Device Manager that show any errors, for any reason. Once you no longer have any disabled USB devices, the Bluetooth device should show back up. On some platforms, this is the #1 cause of Wi-Fi and Bluetooth adapters mysteriously vanishing from the Device Manager. Once you have resolved the USB issue, restart your machine, and check to see if the missing device has reappeared in your Device Manager. 

USB Error

  • If you do not have any disabled USB devices, or any with errors, or if you have resolved that issue and the Wi-Fi or Bluetooth adapter has not reappeared in the Device Manager, then you will need to update your chipset drivers, and possibly your machine or mainboard’s BIOS. We have noted that some platforms have chipset drivers that are buggy enough that they absolutely will experience this issue if their chipset drivers are not updated. You will need to obtain these drivers from your mainboard or machine manufacturer’s support page. If you cannot tell which drivers are the chipset drivers, it is generally recommended that you simply update all of the offered drivers, except for the Killer Network card drivers, which you should get from us, as they are likely more recent. If there is a BIOS update available, then updating the BIOS is also recommended, especially if the BIOS update notes mention anything that might pertain to this situation. Make certain that you at least update the chipset and USB drivers, if applicable. Some platforms combine the USB drivers into the chipset drivers, so you may not see a separate download. Once you have done these updates, restart the machine, and see if the missing device reappears in the Device Manager. Depending on what is available, the best order in which to update is as follows:
    1. Update your BIOS from your machine or mainboard's support page.
    2. Update your chipset drivers from  your machine or mainboard's support page.
    3. Update the USB drivers from your machine or mainboard's support page. If none are listed, they are probably rolled into the chipset driver.
    4. Update all other drivers available from your machine or mainboard's support page, except Killer Networking and Bluetooth drivers, which you should get from us.
    5. Restart your machine by clicking Start > Power > Restart
  • Windows itself can also play a part in the disappearing device. The Anniversary Update saw many such devices vanish, so much so that the Creator’s Update added a Bluetooth troubleshooter to Windows 10. Make sure that your Windows installation is up to date by using Windows Search to search Windows Update

    windows update

    then press Enter, and click Check for Updates

  • Once it has downloaded and installed everything it finds, restart the machine, and repeat this process until Windows Update finds no updates directly after restarting. Once this happens, check to see if the device has reappeared in the Device Manager. If this doesn’t help, and the issue is Bluetooth related, you can try troubleshooting using Windows built-in troubleshooter. Microsoft has instructions here - https://support.microsoft.com/en-us/help/14169/windows-10-fix-bluetooth-problems-faq
  • If the device is still missing from the Device Manager, then that means that it isn’t the chipset drivers (or at least it isn’t only the chipset drivers) that is not properly enumerating the device, but rather the BIOS itself. In this case, you will need to discharge the machine to force the BIOS to re-enumerate all of its hardware. Before you do this, make sure that you have updated the BIOS to the latest version, from the mainboard or machine manufacturer’s website, so that you address the flaw that caused this issue in the first place. Once that BIOS update is in place, and you have confirmed that the machine has booted back up, but the device is still not appearing in Device Manager, shut the machine back down, and unplug it from the wall. You will now need to fully discharge the machine.
    • If this is a desktop, you will need to remove the side panel, discharge yourself of static electricity on something metal (your computer’s case might work, or possibly your desk) and look for the CMOS battery. It is a large coin-cell battery. Remove that battery. Sometimes it’s easier with a flathead screwdriver, but it should be fairly simple to remove. Once you have removed that battery, press the power button on the machine 2-3 times to completely discharge it, then replace the CMOS battery and the case. If you are not comfortable doing this on your own, please refer to your mainboard or machine's support. 
    • If this is a laptop, hopefully it is one where you can easily remove the battery. This will be specific to your model of laptop, so you may need to refer to your owner’s manual, or your laptop’s support website. Some MSI models are held in with a single screw. If you are able to remove the laptop battery, do so, and then press the laptop’s power button a few times to fully discharge it. If you are unable to remove the laptop’s battery, temporarily change the power plan to a setting that does not allow it to sleep when the battery is low, then run the laptop until it discharges itself. Once it has discharged itself, press the power button a few times to make sure it is fully discharged.
    • Once you have a fully discharged machine, put it back together, plug it back in, and let it boot in to Windows. You may see a message mentioning setting the BIOS to defaults, or something along those lines. This is nothing to be alarmed about – simply confirm that you want it set to defaults, unless you had set custom settings, in which case, you will need to re-set those custom settings. In the future, this message may be a warning that your CMOS or laptop battery is dead or on its last legs, but for now, we know that you discharged the machine on purpose, so we can safely ignore this warning. Once you are booted back in to Windows, check the Device Manager to make sure that the missing Wi-Fi or Bluetooth device is no longer missing.
  • In some very rare cases, the device may not show up because the machine was not fully discharged. We have had users report that they were able to repeat the steps to discharge their machines a second time, and have had success after that. Once the updates were in place, and the devices shows up, that is usually the end of the problem.

One final step that you can take, if you are willing and able to do so, is to physically reseat your Wi-Fi adapter. The Wi-Fi and Bluetooth device are on the same card, so there is only one adapter to reseat, and reseating this adapter only requires that you remove one screw, slide it out of the slot, then slide it back in and screw it back down, being careful not to dislodge or damage the attached antenna leads. However, the difficulty in getting to this adapter and performing this step will vary depending on your machine or mainboard, and your level of expertise. You may wish to consult with your mainboard or machine manufacturer’s support at this point. If you have followed all of the other steps, and the device still has not reappeared, the device, or the mainboard, may also be physically damaged, and in need of repair, which would also necessitate contacting your mainboard or machine manufacturer’s support for RMA or repair options.  

Slow Network Speeds

 

Slow Network Speeds

If you are experiencing slow Internet or network speeds, you can follow this troubleshooting guide to address and correct the most common problems. 

If you haven't already, please try installing the latest Killer Control Center from our website, and only from our website. It includes many fixes and improvements that are not be included in other packages. If you are still using the Killer Network Manager, you'll want to download the Killer Control Center, and then manually uninstall the Killer Network Manager, as well as the "Killer Drivers" entry in your programs list. You can find the latest Killer Control Center here: http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. Please download and run this installer, which will also install the latest drivers. If you experience any problems installing the Killer Control Center, you can refer to this article for help - http://www.killernetworking.com/driver-downloads/kb/faq/6-troubleshooting-killer-ethernet-wireless-drivers-software 

Once you have successfully updated your drivers, you will want to restart your computer by clicking Start > Power > Restart. It is important to note that closing the lid or pressing the power button on many modern computers does not shut them down, but instead activates sleep mode. You must restart them by clicking Start > Power > Restart for them to restart.

If updating the drivers does not solve the issue, try resetting your networking equipment in this specific order, even if you have reset your some or all of your equipment previously. This order is proven to help your devices sync up properly, and will help to get a clean slate with further troubleshooting. Doing this can help even if only one device is experiencing problems. 

  1. Shut down your computer.
  2. Locate your modem and note the lights on your modem when it is normal and ready. There may be a "Ready" light.
  3. Unplug your modem, router, and any switches or hubs, between your computer and the modem, as well as any wireless boosters or access points, and leave them all unplugged for now.
  4. Plug in your modem.
  5. Wait until your modem's lights show normal operation again.
  6. Plug in your router, if you have one, and give it about five minutes to boot.
  7. Plug in anything else between your computer and the modem
  8. Power on your computer.
  9. Once your computer is booted and connected to the Internet, you will want to reset its network stack:
    1. In the search box on the taskbar, type Command prompt, right-click Command prompt, and then select Run as administrator > Yes.
    2. At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
      • Type netsh winsock reset and press Enter.
      • Type netsh int ip reset and press Enter.
      • Type ipconfig /release and press Enter.
      • Type ipconfig /renew and press Enter.
      • Type ipconfig /flushdns and press Enter.
  10. Now reboot your machine once more and test to see if the issue is resolved.

If not, the next step is to make sure that your Windows installation is completely up to date. Microsoft has been updating Windows more often than with any previous release, so it's important to keep things up to date. To do this, simply search Windows Updates, hit Enter, and then click Check for Updates. If your machine finds updates, check again once it finishes installing. Once your machine finds no updates, restart again, and then check for updates once more. Once your machine finds no updates upon a fresh reboot, your Windows installation should be fully up to date.

If you have performed the above, and you are still experiencing issues with slow network speeds, there are some other things to try:

  • Set a benchmark. Place the device in one place, if dealing with Wi-Fi, and run a test using one speed test. Turn off all other network usage while troubleshooting. Speedtest.net and Testmy.net are both good bandwidth tests. Run three tests in short succession and record an average as your starting point. Test after each change to see if there has been improvement. Record what you changed, and what the speeds the change produced. If the change seems dramatic, restart the machine and test again to be sure. 
  • Make sure your BIOS is up to date from your machine or mainboard manufacturer's support page.
  • Make sure your chipset drivers are up to date from your machine or mainboard manufacturer's support page.
  • Make sure all of the other drivers are up to date from your machine or mainboard manufacturer's support page. You can safely download and install all available driver packages. If the driver does not apply, it will either not install, or will not be used. If the only options in a driver installer package are "Repair" or "Uninstall", choosing "Repair" will update the driver, if there is a newer driver available.
  • Update the firmware on your router if you own the router.
  • Update the firmware on your modem if you own the modem, but only if your ISP accepts the firmware. Your ISP's support team can help you with this. Some ISPs also have this information listed somewhere, but they may need to do something on their end if you update the firmware, in order to re-authorize your modem. 
  • Have your ISP update the firmware on your modem or router if they own your modem or router.
  • If you are using Wi-Fi, minimize the number of solid objects between the access point's antenna and the device suffering from low speeds, using line-of-sight. Moving a device or antenna even an inch to one side could bypass multiple solid objects, making an enormous difference. 
  • If you are using Wi-Fi, use the Killer Control Center's Wi-Fi analyzer to make changes to your router's settings. 
    • 5 GHz routers should be set to channels 36-48, and/or 149-165 that are as far away from other channels as possible.
    • 2.4 GHz routers should be set to channels 1, 6, or 11, depending on which channels have the least powerful conflicting radios present.
    • Sideband, or side channel should be set to 20 MHz if there are many other Wi-Fi access points in your area, especially if you are forced to share a channel. Higher side channels are less powerful, but provide a wider band, allowing the signal to get around solid objects better, theoretically improving performance in situations where there are no interference concerns, but the Wi-Fi signal needs to "get around" solid objects. Many, however, report that, in real life testing, 20 MHz still provides the better signal, so your mileage may vary. 
  • If you are using Wi-Fi and your router has both a 5 GHz radio and a 2.4 GHz radio, name them something different. Although it might seem simpler to name them the same thing, many routers do not handle this very well, and you can see performance issues by having them named the same thing. Many people opt to simply add "5" to the end of the 5 GHz radio. 
  • If you are using Wi-Fi extenders, name each of your extenders something different, so that you know which access point you are connected to. Wi-Fi extenders have limited radio capacity, and will, always provide at least slightly slower speeds than connecting directly to the router, as they have to use the same radio to receive and transmit, at the same time. 
  • If it seems like other machines using the same access point are having no issues, try to verify this. Borrow their machine and run a speed test. Ask for permission first, of course. If you are experiencing issues on a public access point, you might just find that the public access point is just terrible, and that no one else is having a problem because you're the only one playing latency-intensive first person shooters. 
  • If you are using a Wireless-N router in a crowded Wi-Fi environment, you are very likely to encounter drops and speed issues no matter what settings you change. Unfortunately, the 2.4 GHz spectrum is very limited on how many channels are available, and conflicts arise quickly. Updating to a Wireless-AC router may be required to increase your speeds and reduce wireless drops. 
  • If you are using an antivirus or firewall application, try completely uninstalling it for testing purposes. Unfortunately, simply disabling these programs do not work for troubleshooting purposes, as they often continue to manipulate network traffic. They must be fully uninstalled. If you notice that your speeds increase dramatically with the antivirus or firewall application uninstalled, try installing a freshly downloaded version from their website. If that doesn't help, then the issue may be one with the antivirus application itself. In that case, you will want to contact the support team for the antivirus application. 

If you are unable to get your speed issues sorted out using the above tips, feel free to contact us directly using the information below! 

 

How to Update or Install The Killer Control Center

1.0 

Updating or Installing The Killer Control Center

You can find the latest Killer Control Center, as well as the latest drivers for your Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500, here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64.

The installer will automatically detect and install on any 64-bit version of Windows 7, 8.1, and Windows 10.

If you are using an older version of our suite, such as the Killer Network Manager, or you have not updated your network adapter drivers since your last Windows feature update (for example: Anniversary Update, Creator’s Update), then we suggest downloading the Killer Control Center, but uninstalling any application with the "Killer" name from your Apps and Features menu (accessible by right-clicking Start) and restarting your machine before installing the Killer Control Center.

 

How to Update or Install The Killer Network Manager

4.0 

Updating or Installing The Killer Network Manager

The Killer Network Manager is our outgoing performance suite. It is no longer being updated, and does not contain the latest Ethernet or Wi-Fi drivers. We encourage all users of the Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500 to upgrade to the Killer Control Center, found here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. This includes users whose machines came with the Killer Network Manager preinstalled. There is no need to continue using the Killer Network Manager. 

For a smooth installation, download the latest Killer Control Center installation package, then uninstall all Killer products from your Apps and Features menu, which is accessible by right-clicking Start, then restart your computer, and double-click the new installation package to install the new Killer Control Center.

The old Killer Network Manager suite is still available for download here - http://www.killernetworking.com/driver-downloads/item/e2200-e2400-wireless - but will no longer be updated, and may not be fully compatible with future Windows updates, antivirus suites, or other applications that manipulate network data. 

Ad-Hoc and Hotspot Functionality with Killer Adapters in Windows 10

 

Ad-Hoc and Hotspot Functionality with Killer Adapters in Windows 10

You may wish to create an Ad-Hoc or Hotspot network with your Killer Adapter on your Windows 10 machine.

With Windows 10, all Ad-Hoc and Hotspot functionality has been officially moved away from the drivers, and into the operating system itself.

If you would like to create a Hotspot or Ad-Hoc network with Windows 10, you simply need to click Start, type Hotspot, and press Enter. All of the relevant settings for your Hotspot network will be on that page.

Hotspot Settings
With Windows 10, this is the current official limit of Hotspot or Ad-Hoc functionality.

The Windows 10 version of our driver does not support the "Hosted Network" feature because Microsoft's own WDI driver does not have support for this. Microsoft is having all wireless vendors move to the WDI model, thus this feature will not work on Windows 10 drivers until after (and if) Microsoft expands support for SoftAP/Wi-Fi Direct.

In the meantime, if you need this feature back for certain older applications that made use of their own Hotspot or Ad-Hoc features, you can load the Windows 8.1 drivers via Device Manager from our INF download. We have verified that this works, and have had confirmation from other users as well.

http://www.killernetworking.com/driver-downloads/item/killer-drivers-inf

However, we cannot guarantee that Windows Update will not automatically update these drivers, or that they will work flawlessly with Windows 10, as they are, after all, Windows 8.1 drivers. Use Windows 8.1 drivers in Windows 10 at your own risk.

Issues When Installing Windows 7 Drivers

 

Users may encounter errors when installing drivers in Windows 7. This can be resolved by installing an update to Windows 7 that enables SHA-2 code signing in Windows 7, allowing the older operating system to use the newer device drivers. If allowed to fully update, Windows Update should install this update for you automatically. However, if you are unable to connect to the Internet, you may need to use a USB thumb drive, or some other media, to install this update on the machine on which you wish to install Windows 7. You can read more, and find the appropriate update for your situation here - https://docs.microsoft.com/en-us/security-updates/SecurityAdvisories/2015/3033929

Windows Server Drivers

 

Windows Server Drivers

From time to time, we receive requests for Windows Server compatible drivers for our network adapters. Although we do not provide package installers for Windows Server editions, our drivers are Windows WHQL certified, and as such will work with recent Windows Server editions, so long as they are installed manually from the Device Manager using our .INF files.

You can download the .INF files from this location - http://www.killernetworking.com/driver-downloads/item/killer-drivers-inf

If you need assistance manually installing the .INF files using Device Manager, you can follow our guide here - http://www.killernetworking.com/driver-downloads/kb/faq/10-installing-drivers-device-manager

The Killer Control Center is not availalbe on Windows Server editions. 

Avoiding Broken M.2 Antenna Connectors When Changing Adapters

 

M.2 WiFi modules and their connectors continue to get smaller as system providers continue to make thinner notebooks. This makes it much more difficult to disconnect the antenna lead from the module by hand when changing M.2 adapters. In order to properly disconnect the antenna from the module, all wireless module makers now recommend using a specially designed tool. For the Killer Wireless AC modules, we recommend using an IPEX MHF4L 90609-0001. This will greatly reduce the chance of damage to the wireless module connector or to the antenna connector. If you have further questions, please email us at killersupport@rivetnteworks.com.

Installing Bluetooth Drivers From Device Manager

Wifi and Router or Modem Issues With Killer 1535

 

Router or Modem Issues With Killer 1535

This article is intended to cover all issues that affect any access point, be it a router or modem, that occur when the Killer Wireless-AC 1535 connects or is connected.

The 1535 is a cutting edge Wireless-AC device with MU-MIMO and Transmit Beamforming technology and, as such, not all access points have firmware already installed that is able to handle the connection. Problems that some of our users have reported include:

  • Access point restarts or crashes upon connection, requiring restart
  • Access point restarts or crashes after being connected for some time, requiring restart
  • Access point slows dramatically
  • Access point randomly disconnects all connected devices

The fix for this issue will depend on your personal situation.

 

 

You Own the Access Point

In this case, you are connecting to a device, such as a router, that you own, which is then connected to another device, such as a modem, which is owned by your Internet Service Provider (ISP). If the device in question is a modem, please be sure that, even if you own the device, your ISP supports any firmware that you flash onto the modem. Most ISPs maintain a list of accepted firmware versions for each device online.

In many such situations, you can update the firmware of your device to resolve this issue. You should first try to update the firmware through the router's interface, if possible. If that is not a feature of that router, or if that does not solve the issue, check for the latest firmware from the official support page of your router. If the problem is still not resolved, then see if your router is listed below. Listed below are the routers whose model numbers that we are aware of have issues, along with the location of the updated firmware that the router manufacturer has made available to address the issue:

If you own a different model than the one listed above, and updating to the latest firmware that is available from the support page of your router's manufacturer, we suggest contacting the support for your router, we suggest first updating to the latest Killer Control Center, found here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If that does not solve the issue, the next step would be to contact the support for your device and advise them of the steps that you have taken, and ask if they have a beta firmware available. At the same time, please contact our support, as well, using this form - http://www.killernetworking.com/about/contact

 

 

The Access Point is Owned By Your ISP

In this case, it is very possible that the device is running a very old firmware version. Most ISPs only update the firmware at the customer's request, or when it is absolutely necessary in order for the device to continue working on their network, and many ISPs use very old equipment. If you are connecting directly to an ISP owned device, and you are experiencing these issues, then your best bet would be to contact your ISP's support, and request that they update the firmware on the modem. This is usually a simple thing for them to do. If you are unable to resolve this by asking your ISP to update the firmware on the device, please let us know by contacting us here - http://www.killernetworking.com/about/contact - so that we may document the model of the access point that is not fully compatible with our device. In most cases, however, it is due to the age of the device, and a bug in its firmware. If asked, your ISP may be willing to change you to a different model of access point. You might also be able to provide your own access point (sometimes saving a monthly rental fee in the process), or buy your own router to plug into their modem, then use your router as the access point. If you decide to buy your own modem, most ISPs maintain a list of modems that work with their service. If you use multiple devices at the same time on the same access point, there is a good chance that you will see a boost in performance on all devices by providing your own modem. 

 

 

Addressing the Isssue with Drivers

There are some discussion threads where we have commented, linking to specific drivers on our site, where those drivers have now been moved, causing 404 errors, or redirections to this page. Those drivers were links to .INF drivers that could be installed using the Device Manager, to address specific access points crashing when the 1535 would connect to them. These posts and links were created before we had driver-only installers hosted on our website, and were generally just the latest driver-only file that we had available at that moment, as the problem was believed to be cause by the performance suite at the time. You can now download the latest driver-only installer here - http://www.killernetworking.com/driver-downloads/category/other-downloads. However, this will not always solve the issue, as the issue is sometimes not the performance suite, but that of buggy firmware with the access point. If you wish to try and address the issue by using a driver-only install, you will need to download the driver-only installer, then uninstall all "Killer" entries in your Programs and Features menu, restart your machine, then install the driver-only package. This will remove all Killer network management capability.

We have had some reports of users who were only able to keep their routers stable with only one very specific driver version - usually some Windows 8.1 driver used on a Windows 10 machine. In those cases, we will do our best to locate a copy of that specific version for you but, unfortunately for those cases, Windows Update will often update those drivers anyway, and that is completely out of our control. There are some guides out there on how to prevent Windows Update from updating your device drivers, but we have neither tested nor endorse any particular method of doing so, and we cannot say what the repercussions may be. 

 

 

Wi-Fi Issues with Killer Wireless-AC 1535 on Certain Platforms

 

Wireless Issues with Killer Wireless-AC 1535 on Certain Platforms

We are aware that users, on some specific platforms, are encountering Wi-Fi drops, slowdowns, disconnects, and packet loss issues, which are related to certain machines containing the Killer Wireless-AC 1535.

We have been working closely with the manufacturer to root cause the issue, and the manufacturers of these machines have been releasing chipset updates to address the problem. In most cases, users are able to resolve this issue by doing the following:

  • Update the chipset drivers from the manufacturer’s website, which, in many cases, has been updated as recently as October 26, 2017.
  • Update the BIOS from the manufacturer’s website, which has also been updated as recently as October 25, 2017.
  • Ensure that the Windows OS is up to date by using Windows Search to search “Windows Update, then clicking Check for Updates, letting it download and install whatever updates it finds, then restarting the machine, and checking again until no updates are found upon a fresh restart.
  • If the issue persists, please be sure that you are using the most up-to-date version of the Killer Control Center, available here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. The installer should automatically detect your current version of the suite and update on its own, but if you encounter any error, make sure you have the latest installer downloaded, then remove any "Killer" application from your Apps & Features menu (accessible from right-clicking Start), restart your machine, and then double-click the downloaded installer file for the latest suite once your machine has booted back up. 

If you are unable to resolve the issue by following these steps, we encourage you to reach out to us here - http://www.killernetworking.com/about/contact - so that we may help you on a case by case basis.

Please be sure to mention what steps you have already taken to troubleshoot the issue so that we do not unknowingly ask you to repeat steps.

 

No Killer Enabled Devices On Linksys WRT32X

 

Users with Killer Network Adapters and the Linksys WRT32X may see "No Killer Enabled Devices" or "0 Killer Enabled Devices" on the user interface page of their WRT32X. 

The Killer optimization on the WRT32X is compatible with all Killer adapters that work with the Killer Control Center, which includes the:E2500, E2400, E2200, E2201, and all of our Wireless-N and Wireless-AC adapters. 

You must also have a recent version of the Killer Control Center installed. You can find the latest version of the Killer Control Center here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64. If you run into any problems updating your performance suite, you can refer to our installation troubleshooting KB here - http://www.killernetworking.com/driver-downloads/kb/faq/6-troubleshooting-killer-ethernet-wireless-drivers-software.

After you have installed the latest Killer Control Center, if the router still fails to detect the Killer adapters, you may need to unplug the router for ten seconds, then plug it back in. If it still does not recognize the adapters. you may need to restart your computer once more by clicking Start > Power > Restart

If you still experience issues, it is recommended that you contact Linksys Support unless you are having other issues with your Killer adapter, in which case you should reach out to us through the contact form below. 

 

Wi-Fi Channels 12 and 13

 

Some users have reported problems seeing Wi-Fi access points that are using channels 12 or 13. This is a driver issue that will be corrected in later versions. In the meantime, there is a fairly simple registry tweak, which you can perform, that will enable your machine to see these channels. Note that this method has only been tested in Windows 10. If you have success using this method in Windows 7 or 8.1, please reach out to us at the contact information below and let us know!

  1. Click Start
  2. Type regedit and press Enter
  3. Copy the following, and paste it into the bar beneath File, Edit, View, Favorite, Help: 

    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}
     
  4. Then press Enter. It should jump to a point in the registry that looks like the below picture.
    Registry
  5. Each numbered folder within corresponds with a device on your machine. Unfortunately, from here, it's complete guesswork as to which folder equals which device. Fortunately, it's pretty obvious as you click on each folder. For instance, 0006 is my Killer 1525, as you can see in screenshot. If in doubt, look for the "DriverDesc" entry. They're in alphabetical order. But, again, it should be pretty obvious. If you see it talking about Bluetooth, it's the wrong one. Once you find it, you know where the registry portion for your Killer adapter is hiding. 
  6. On the right pane of the registry editor, find the entry marked "AddNewChannelfor11d". This is our holy grail of channels 12 and 13. It is currently set to a value of 0. Double-click it. Change the value to 1, and click the OK button.
  7. Click File then Exit
  8. You have now activated the adapter's ability to see channels 12 and 13.
