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.

 

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. 

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.

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.  

Killer 1535/1525/1435 in Ubuntu/Debian

 

Ubuntu/Debian 14.04

You will first need to install the latest backports package to have up to date drivers. 

https://help.ubuntu.com/community/UbuntuBackports#Installing_Backports

Ubuntu/Debian 16.04

The built in drivers should work without any changes, though you may need to update your wireless firmware:

 

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.164_all.deb
sudo dpkg -i linux-firmware*.deb
sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci

 

Killer Wireless-AC 1535 in SteamOS

 

Killer 1535 uses the included driver in SteamOS, however the firmware needs to be downloaded and updated.

Download:
http://www.killernetworking.com/support/K1535_Debian/board.bin and put it in the /lib/firmware/ath10k/QCA6174/hw3.0/ folder (create the folder if it doesn’t exist)

Download:
http://www.killernetworking.com/support/K1535_Debian/firmware-4.bin and put it in the /lib/firmware/ath10k/QCA6174/hw3.0/ folder as firmware-4.bin.

Create config file with:

sudo nano /etc/modprobe.d/ath10k.conf

 

Installing Drivers from .INF Package Through Device Manager

 

- Install drivers using Device Manager

If you would like to install the Killer E2200, Killer E2400, Killer Wireless-N, or Killer Wireless-AC drivers without the Killer software manually - you can do so using these steps.

First, download the driver only package from: http://www.killernetworking.com/support/Killer-Ethernet-Wireless_INF.zip

After the download is complete, extract the drivers to a temporary location, such as your desktop.

Press Windows key + X
Click Device Manager

Once device manager is open, select the Ethernet Controller, Network Controller, or Unknown device, right click it and click Update Driver Software

This will launch the update driver software wizard

Choose: Browse my computer for driver software

Click Browse... and browse to the location where you extracted the standalone driver package earlier, then click Next

Note: It is recommended that you browse all the way to the right device and right OS. For instance, you can see in the image that we have browsed to C:\drivers\Production\Windows10-x64\ke2200w10 for the Killer E2200 network adapter.

The final screen should show that you have successfully installed the driver. You can now click on Close.

 

The Bluetooth with My Killer Wireless-N or Wireless-AC is Not Working

 

Note: If your Bluetooth device is missing from Device Manager entirely, please see this KB article: http://www.killernetworking.com/driver-downloads/kb/faq/31-bluetooth-missing-from-device-manager

Ensure that you have downloaded the proper version of Killer Bluetooth software for your Killer Wireless card.

  • Please note that the Killer Wireless-N 1202 has a single Bluetooth installer for Windows 7, 8.1, and 10.
  • For Killer Wireless-AC products, please ensure you have downloaded the appropriate version for your adapter and OS, as the Bluetooth software is not unified.

All Bluetooth driver downloads are available here:

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.
