Wireless Not Working After Update / Code 10 Error


Wireless Not Working After Update / Code 10 Error

Some users have contacted us regarding their Killer Networking adapters not working after a Windows Update. This has affected various adapters, including the 1525, 1535, and 1550. Although we are as yet unsure exactly which update is causing this issue, there seems to be a connection with specific machine manufacturers having pushed an outdated version of the Killer Control Center through Windows Update, along with extremely outdated wireless drivers, which leads to a corrupted device driver.

The following troubleshooting steps should allow you to resolve the issue. 

  1. If your machine has Internet access through Ethernet, or if you are able to move files onto the machine using a USB thumb drive or some other medium, clean installing to the most recent version of the Killer Control Center and device drivers is the best way to resolve this issue. Click here for the guide on clean installing the latest Killer Control Center and device drivers. 
  2. (Code 10) If the clean install does not solve the issue, try manually installing the latest device drivers for your Killer Wireless device. This will hopefully replace the corrupted device driver. Click here for the guide to manually install drivers in Device Manager.
  3. If manually installing the driver does not resolve the issue, or if the network adapter is not present in Device Manager, try clean installing the drivers in Device Manager. This is different than clean installing the Killer Control Center or simply manually installing the drivers in Device Manager. This will hopefully remove the corrupted driver from the Windows Driver Store, allowing you to update to a working driver. Click here for our guide on clean installing drivers in Device Manager.
  4. If none of the above resolves the issue, then the issue may be due to something that is not strictly related to your wireless adapter or drivers, but is causing the adapter to malfunction. Check the support downloads page for your machine or motherboard manufacturer and make sure that you have the latest BIOS available, as well as the latest chipset drivers available. 
  5. If none of the above resolves your issue, you may need to uninstall whatever update caused the issue. Click here for our guide on uninstalling Windows Updates. Please note that this guide only refers to Microsoft Windows Updates specifically. It's possible that the update that caused the issue was not an update to Microsoft Windows, but an update to something else on your system. Keep that in mind if you find yourself manually uninstalling recent updates, which is otherwise covered in the linked guide. 
  6. If you have followed every step in this guide and still have not been able to establish wireless connectivity, try discharging your machine to reset the CMOS. Click here for our guide on discharging your machine. 
  7. If none of the above resolved the issue, then you may need to resort to resetting Windows. This may result in lost files and applications, so restoring a backup is preferable, if you have one available. Click here for Microsoft's information on resetting Windows and click "Reset your PC." Please be sure to read exactly what the reset will entail. Alternatively, you may find that other options on that page may better fit your needs. If you do go this route, make sure you install the latest Killer Control Center and drivers as soon as Windows updates to 1803 or later, before other updates can take place. This is best done using our clean install guide (click here). To find out which version of Windows is currently installed, click Start, type winver, and press Enter. Refer to the "Version" number. When resetting  your PC or reinstalling Windows, this number may change as Windows updates. As soon as the build is 1803 or newer, install the latest Killer Control Center and drivers using the clean install guide. 
  8. Unfortunately, if none of the above resolves your issue, your next step will be to contact your machine or motherboard manufacturer for RMA or repair options. When a wireless network adapter's driver is updated, the firmware on the chip is flashed. If none of the above solved the problem, then this indicates that the adapter is no longer capable of accepting a flash, and will need to be replaced. Alternatively, the machine or motherboard manufacturer may have an unpublished BIOS update or chipset driver that can resolve the issue. 

Windows Update Slowed Or Broke Internet Connectivity


Windows Update Slowed Or Broke Internet Connectivity

Update September 15 2018 - Windows 10 1809, which is currently being released in October 2018, seems to have caused many of these issues since its release. If you are unable to resolve this issue by following this knowledge base article, you may need to revert your operating system back to the Windows 10 1803 to restore functionality. While we do not yet have a guide for this, there are quite a few around the web, such as this excellent guide for rolling back to Windows 10 1803. 

Windows users will periodically run into situations where a Windows Update either slows or completely removes their ability to connect to the Internet. This is usually due to some component of the updated operating system not functioning well with older drivers, though sometimes Windows Updates have been known to just break things for no reason. In the past, Microsoft has even recalled some updates. Whatever the reason, if you know that your machine was working well before the Windows Update, the best way to restore functionality is often to remove that Windows Update. There are a few ways to do this.

First, you should check Device Manager and make sure it's not a simple error. To do that, right-click Start, click Device Manager, then double-click Network Adapters and look for your network adapter, be it a wireless adapter or an Ethernet adapter. If you find your network adapter, and it has a Code 10 error on it, then click here for a guide to manually install a driver for the device. If that's not the issue, or if that doesn't fix it, read on.

Try System Restore First

This is the fastest, easiest way to get your system back in working order, when it's available, and when it works. Luckily, if it doesn't work, it won't do anything at all. Here are the steps:

  1. Temporarily uninstall any third party antivirus application as these will almost universally prevent System Restore from restoring properly, resulting in an error. 
  2. Click Start
  3. Type system restore and click Create a Restore Point (don't worry, you're not doing that, that's just what comes up)
  4. Click the System Restore button.
  5. Check the "Recommended restore" option to make sure the date is very close to when the Windows Update happened, but still before it happened. If so, click Next.  If not, you can click "Choose a different restore point," but those will usually be earlier dates, if any. 
  6. There may be another confirmation prompt or two, depending on your build of Windows, but after that, System Restore should do its thing. This can take a while, so be patient. 

Uninstall The Windows Update

  1. If the System Restore doesn't work or isn't available, you will need to uninstall the Windows Update. This works surprisingly well and generally does not have many drawbacks, though making a back-up is definitely recommended. After you make your backup, you will want to set a System Restore point, as they are much faster and easier to use than restoring a backup, if necessary. Creating a System Restore point is similar to using one:
    1. Click Start
    2. Type system restore and click Create a Restore Point
    3. Check to make sure your system disk, probably (C:), has Protection "On". If not, click it Configure, and click Turn on System Protection, move the slider until it's using around 5% - 10%, then click Apply > OK. 
    4. Click Create
    5. Name it something you'll remember, like "Uninstalling Windows Updates." It will append the date, so you'll also have that information. Click Create and give it some time to finish.
    6. Once it is finished, close the "System Properties" window that opened when you searched for System Restore.
  2. Now to uninstall that update. This is surprisingly easy when you know where to look. Click Start, and type Windows Update.
  3. Click Windows Update Settings
  4. Click View Update History
  5. Click Uninstall Updates
  6. Click the Installed On column header to sort by the Installed On date until the newest updates are at the top. 
  7. This part is important. Even though you sorted by newest updates, you're probably still not looking at updates for Microsoft Windows. Instead, you're probably looking at updates for Microsoft Office, or Microsoft Visual C++, or possibly some other Microsoft product that you didn't even know you had. You can tell because, just under "Name", it will list the name of the application with no other information to its right. Scroll until you find Microsoft Windows, and you will have found the updates that we're looking for.
  8. You will want to uninstall any update that took place between now and when your machine last worked normally. To do that, click the update, and click Uninstall, which will hopefully appear beside "Organize" at the top of the columns. If the option to uninstall does not appear, this means that you cannot uninstall that update and keep your operating system intact. The same goes for updates that are not listed. 
  9. If you are unable to uninstall the update, you may have to resort to restoring a backup or, if that's not possible, resetting Windows. Click here for Microsoft's article on resetting Windows. However, if the only issue that you are having is with your Killer products, please reach out to us first at killersupport@rivetnetworks.com so that we can see if we can help you out. 

Update Your Drivers As Soon As You Have Internet Access!

As soon as you are able to restore Internet access, be it with a System Restore, a backup restore, or uninstalling the Windows Update, make sure you update your drivers! This should prevent the issue from happening when Windows Update invariably installs the same update again in the future. You can find our driver downloads here - https://www.killernetworking.com/killersupport/ - and if you have any issues installing the latest Killer Control Center and device drivers, we suggest using our clean install method here - https://www.killernetworking.com/killersupport/driver-downloads/kb/faq/105-clean-install-the-killer-control-center.

This can typically be resolved by uninstalling and reinstalling the Killer Control Center after the Windows 10 1803 update. Here is the step by step:

  1. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  2. Download the installer for the Killer Control Center that is best for your version of Windows 10. You can check this by clicking Start, then type winver and press Enter.
  3. Restart your computer by clicking Power > Start > Restart
  4. Run the Killer Software Uninstaller Tool. When it is finished, it will say REBOOT REQUIRED.
  5. Restart your computer by clicking Power > Start > Restart
  6. Once your computer has restarted, run the Killer Control Center installer that you downloaded, and follow the prompts to complete the install.

Please note that the Killer Software Uninstaller removes files and folders from previous installations that will not be removed simply by uninstalling old versions.

Prompts to Update Killer Control Center


Prompt to Update Killer Control Center

Users may see a prompt to update the Killer Control Center. This prompt is caused by a Windows Update that was not instigated by us but, nevertheless, targeted systems that came with the Killer Control Center preinstalled. Unfortunately, if you are here, you have probably already noticed that this prompt does not include any instructions on exactly how to update the Killer Control Center. 

The best way to eliminate this prompt is to manually update the Killer Control Center from our website. Here are the steps:

  1. If you are using Windows 10 and don't already know which build, find out which build of Windows that your machine is currently running. If your computer has completed the Windows 10 Spring 2018 update, you are running version 1803. Otherwise, or if you don't know, continue reading.
    1. Click Start
    2. Type winver and press Enter
    3. A box will appear with some information about Windows. There will be a 'Version" number. It will probably be either 1709 or 1803. 
  2. Download the correct installer for your version of Windows.
    1. Windows 7, Windows 8.1, and Windows 10 Version 1709 and below should download this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
    2. Windows 10 Version 1803 and above should download this installer - https://www.killernetworking.com/driver-downloads/item/kcc-uwd
  3. Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe
  4. Run the Killer Software Uninstaller Tool. It is not necessary to scan, and the scan may not find anything. Regardless, click Remove Killer Software, and give it some time to run. When it is finished, it will say "RESTART REQUIRED."
  5. Restart your machine by clicking Start > Power > Restart
  6. Once your machine has booted back up, run the installer that you downloaded for the Killer Control Center. Follow the prompts to complete the installation.

You should now have the latest Killer Control Center and device drivers installed, and should no longer see the update prompt.
