Killer Network Adapters and KRACK Exploit

 

We are aware of the current concern involving the KRACK vulnerabilities in WPA2-PSK Wi-Fi encryption.

All of our current line of network adapters are fully supported only on the current versions of Windows operating systems (Windows 10, 8.1, and 7). As this is a GTK Key exploit, our users are largely safe, as Microsoft has already patched these operating systems to address the issue (https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2017-13080), and the operating system is the primary key handling layer.

No Wi-Fi Access Points with 1525 Using Killer Control Center 1.4.1500

 

UPDATE: This issue only affects users who have installed Killer Control Center 1.4.1500, or who installed drivers from that same version number of driver installer. If you are using the Killer Control Center, you can check your driver number by clicking the Settings button in the Killer Control Center. Version 1.4.1503 has now been released, and fixes this issue. Users with this problem should be able to simply download the package from here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64 - and install it. It will update the components automatically. If the installer asks to close the applications in order to update them, keep telling it to close the needed applications, and it will finish the install after a few tries, if necessary. If you are unable to fix the issue in this manner, feel free to contact support. 

We are aware of an issue with Killer Control Center version 1.4.1500 with the Killer Wireless-AC 1525 adapter, where no Wi-Fi access points will show after installing. We are working on a fix for this issue, and will be releasing it shortly, hopefully before October 13th, 2017. In the meantime, we suggest any users who encounter this bug download version 1.4.1494 (64-bit link), uninstall anything "Killer" under Apps and Features, restart your machine, and then install the downloaded version 1.4.1494. This should resolve the issue until we release the fixed build. We appreciate your patience! 

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 September 2017.
  • Update the BIOS from the manufacturer’s website, which has also been updated as recently as September 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.

 

How Do I Update or Install 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.

 

"This Device Cannot Start (Code 10)" in Device Manager

 

code 10 device cannot start

We have been receiving reports from some users that they are seeing this error on their Killer Networking device in their Device Manager. This usually occurs after they have used the Device Manager to update their drivers, or after Windows Update has updated their drivers. There seems to be a problem with the driver that Microsoft is using when updating machines through their service.

If you encounter this error, it can generally be resolved by updating to the latest Killer Control Center suite from our site, which you can find here - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64.

Once you have updated, restart your machine, and the error should be cleared. Please feel free to contact support if you continue to see this error after updating your drivers.

 

How Do I Update or Install 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. 

Error 2753. The File 'xtendsoftapservice.exe' is Not Marked for Installation

 

Some users may encounter this error when updating their drivers or Killer Control Center, or when uninstalling the Killer Control Center.

Even if you are in the process of updating the Killer Control Center, the issue is that the installer is unable to find this file in order to uninstall it, which is a necssary step for installing the latest suite.

The problem is that the file is either not present, or is not correctly flagged in the registry. This is a bug that was introduced in a few versions of the suite when it was present on your machine during a major Windows feature update, or an upgrade to Windows 10 from another version.

This issue can be resolved by following these steps:

  1. Download the latest Killer Control Center and keep it somewhere handy, to install when you're finished uninstalling the old suite - http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
  2. Download Microsoft's tool for fixing problems that block programs from being installed or removed - https://support.microsoft.com/en-us/help/17588/fix-problems-that-block-programs-from-being-installed-or-removed 

    microsoft uninstall fixit2
















  3. Once you have both of those things downloaded, uninstall all Killer products from your Apps and Features menu, which you can access by right-clicking Start.

    right click start uninstall killer

  4. You may encounter that same error - Error 2753. The File 'xtendsoftapservice.exe' is Not Marked for Installation - and that is fine. When you do, skip that application, and uninstall any other applications from "Killer" including "Killer Drivers."

  5. Now run the tool from Microsoft. 

  6. For the first menu, you will simply click Next

    ms uninstall fixit 1

















  7. Then after a moment of "Detecting Problems", it will ask if you are having a problem installing or uninstalling a program. Even if you are trying to update or install the Killer Control Center, the actual problem is happening when the installer attempts to uninstall the old suite, so you will choose Uninstalling

    ms uninstall fixit 2

















  8. At the next prompt, the program will ask you to choose from a list of programs. Find the Killer-related program in the list. It may not be the same as the one in this screenshot, but choose whichever Killer suite the program finds, and then click the Next button. 

    ms uninstall fixit 3

















  9. The tool will then proceed to erase the parts of the Killer suite that the installer was unable to remove from the registry. If the program is not listed, you have the option of choosing "Not Listed", and the tool may still find the pieces in the registry that need to be removed. However, it is hard to duplicate that particular scenario, so providing a screenshot is not possible, but it is fairly self-explanatory. 
  10. Once the tool has finished doing its work, you will want to restart your machine once more, and then install the latest Killer Control Center, which you downloaded previously.
  11. If you have any further questions, feel free to contact support at the link below! 

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

 

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.
  • 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.  

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. 

 

 

Updating or Installing Killer Drivers & Software (Ethernet and Wi-Fi)

 

If you are experiencing a problem with your network driver, or you suspect that your network driver or performance suite may be causing a problem or not performing correctly, you can either update your performance suite by downloading the latest package from your machine or mainboard’s manufacturer, which may include optimizations that are specific to your platform, or you can download the latest Killer Control Center (which replaces the Killer Network Manager) directly from us, at this location.

http://www.killernetworking.com/driver-downloads/item/killer-control-center-x64

This download, which is the latest performance suite, as well as the latest driver package, applies to the following prodcuts: Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500 on Windows 10, 7, and 8.1. 

The Killer Control Center should be able to automatically detect previous installations and update them on its own. If it cannot, or 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 anything with the "Killer" name from your Apps and Features menu and restarting your machine before installing the latest Killer Control Center. 

Please note that the Killer Control Center that is available on our site, while including the latest optimizations for the most recent Windows updates and compatibility fixes for other applications, may not include integrations with your machine or mainboard manufacter’s other gaming applications, should they exist.
