Updating or Installing The Killer Control Center
The Killer Control Center installers contain drivers for the Killer Wireless-AC 1525/1535/1435, Killer Wireless-N 1202/1103, Killer E2200, Killer E2400, and Killer E2500. The Killer Control Center can be installed on any system with one, or multiples of these network adapters. It cannot be installed on machines with the E2100, Xeno Pro, 2100, M1, or K1. These are legacy devices that are no longer supported, and no longer receive driver updates.
The first step in updating or installing the Killer Control Center is download the correct installer package. There are currently two different Killer Control Center installers:
Choosing the Correct Installer
Those using Windows 7, Windows 8.1, and any version of Windows 10 prior to 1803 (April 2018 Update) should use this installer - https://www.killernetworking.com/driver-downloads/item/killer-control-center-x64
Those using Windows 10 1803 (April 2018 Update) or later should use this installer - https://www.killernetworking.com/driver-downloads/item/kcc-uwd
If you are using Windows 10, and you are unsure which version you are running, you can find out by clicking Start, then typing winver and pressing Enter. A box will appear, which will give you information about Windows, including the version number.
For more details on the differences between the two packages, please see this article - https://www.killernetworking.com/driver-downloads/kb/faq/100-which-killer-control-center-should-i-install
Once you know which version to download, and have downloaded it, double-click the installer to install both the latest drivers for your Killer devices, and the latest version of the Killer Control Center.
If all goes well, you can stop here.
Errors or Other Issues When Installing
If you encounter any errors or problems when installing, first try uninstalling all versions of the Killer Software that are currently on your machine. We have developed a tool to make this very simple. Please follow the steps below:
- Download the Killer Software Uninstaller Tool - https://www.killernetworking.com/support/KillerSoftwareUninstaller.exe (please note that this is not the old Killer Remover tool - this is much more comprehensive)
- Make sure you have the installer for the Killer Control Center that you will be installing. Return here if you aren't sure.
- Run the Killer Software Uninstaller Tool. There are two buttons - one for scanning, one for uninstalling. You do not have to scan. The scan might not find any software installations, but there may still be services installed on your machine that are preventing the installation of the current suite. Regardless of what the scan says, if you are having issues installing, make sure you click Remove Killer Software. When it is finished, it will say "RESTART REQUIRED"
- Restart your machine by clicking Start > Power > Restart
- Once your machine has completed restarting, run the installer for the Killer Control Center.
If you are still unable to install the Killer Control Center, please try using Microsoft's tool for fixing problems that block programs from being installed or removed. You can find our guide for using this tool here - https://www.killernetworking.com/driver-downloads/kb/faq/90-microsoft-tool. This tool is very effective because, if you are still having problems by this point, the issue is very likely caused by files that have been shuffled around during a Windows Update.
If the Microsoft Tool does not solve the issue, please submit a ticket to our support, along with an install log for us to analyze, by following these steps:
- Run the installer for the Killer Control Center one more time, so as to create the most recent possible information in the install log.
- After the installer fails, access your TEMP folder by clicking Start, then typing %TEMP%, then pressing Enter.
- Arrange the files in that folder by "Date Modified" so that the most recently modified files are at the top.
- You will see many files. Find the most recent file that begins with MSI and ends with .LOG. Move or copy that file to a place you will remember.
- Click Support > Contact Support at the top of our website, and be sure to click the folder and attach that .LOG file. In your ticket, please also mention any errors that you might have seen when attempting to install the Killer Control Center.

Which Killer Control Center Should I Install?
Users may notice that we often host more than one version of the Killer Control Center available for download from our website. This article will summarize the difference between the versions available, and hopefully give the user an idea of which installer they should download and use.
A note on device compatibility - All versions of the Killer Control Center support all Killer Wireless adapters, as well as the E2200, E2400, and E2500. The E2100, 2100, K1, M1, and Xeno Pro are legacy devices, and no longer receive driver updates.
A note on the Killer Network Manager - The Killer Network Manager is our deprecated performance suite. It does not contain current drivers. Users are free to use the Killer Network Manager if they like, but, as it is no longer in development, the first step in troubleshooting should be to uninstall the Killer Network Manager and install the Killer Control Center.
A note on finding your Windows version number - You will see Windows version numbers referenced in the following information. You can find your Windows version by clicking Start, then type winver and press Enter. You will see a box with information about your Windows install, including the Version, which is probably 1709 or 1803, as of June 5 2018.
The current Killer Control Center versions are as follows, as of June 5, 2018:
What is this? This is our previous release, which was well tested and troublefree on Windows builds 1709 (Fall Creator's Update) and 1803 (April 2018 Update). This package contains the latest drivers for all Killer Networking devices, except for the Killer Wireless-AC 1550, as well as the Killer Control Center performance suite. The included driver for the Killer Wireless-AC 1550 is not known to be problematic, but our other package includes a more recent driver for this device.
What's new from the previous release? A new, updated driver for the Killer Wireless-AC 1550.
Who should use this? All Killer Network adapter owners who are using Windows 7 and Windows 8.1, as well as those using Windows 10, who have not yet updated to Version 1803 (Windows Spring Update), or who would prefer to not install the Killer Control Center through the Windows Store.
What if this will not install? Click here for troubleshooting steps and scroll to the bottom to Errors or Other Issues When Installing
Special conditions for this release: Unlike the other package, this release uses a regular installer, and does not go through the Windows Store.
What is this? This version is a major update. This is our most recent release, which has been tested primarily with Windows 10 version 1803 (April 2018 Update). This package contains the latest drivers for all Killer Networking devices, as well as the Killer Control Center performance suite. The installer will first install device drivers, and then redirect to the Windows Store to install the Killer Control Center software. Please note that the version number listed here is the version of the installer. The version of the Killer Control Center that the Windows Store installs will be different.
What's new from the previous release? A new, updated driver for the Killer Wireless-AC 1550, the debut release of Wireless xTend for Killer 1550, and many other minor enhancements that are too numerous to list. Wireless xTend for Killer 1550 allows owners of the Killer 1550 to turn their machines into wireless access points, xTending the range of the currently connected wireless network through their computer.
Who should use this? All Killer Networking adapter owners who are using Windows 10 version 1803 (April 2018 Update). Those using the Windows Insider Preview versions of Windows 10 are also encouraged to use this version, and provide us with any feedback, should you encounter any issues.
What if this will not install? Click here for troubleshooting steps and scroll to the bottom to Errors or Other Issues When Installing. If you are unable to install this version, please try installing version 1.5.1859 above after submitting your install log. It is important that you submit your install log before installing 1.5.1859, or the install log will reflect the results of that install instead of reflecting the results of your attempted install of 1.7.1016.
Special conditions for this release: This version will install on versions of Windows 10 that are older than version 1803 (April 2018 Update), but many things will not function well. We highly recommend installing this version only on Windows 10 version 1803.

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: https://www.killernetworking.com/driver-downloads/kb/faq/22-update-killer-control-center.
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.
- Shut down your computer.
- Locate your modem and note the lights on your modem when it is normal and ready. There may be a "Ready" light.
- 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.
- Plug in your modem.
- Wait until your modem's lights show normal operation again.
- Plug in your router, if you have one, and give it about five minutes to boot.
- Plug in anything else between your computer and the modem
- Power on your computer.
- Once your computer is booted and connected to the Internet, you will want to reset its network stack:
- In the search box on the taskbar, type Command prompt, right-click Command prompt, and then select Run as administrator > Yes.
- At the command prompt, run the following commands in the listed order, and then check to see if that fixes your connection problem:
- Type ipconfig /release and press Enter.
- Type ipconfig /flushdns and press Enter.
- Type ipconfig /renew and press Enter.
- Type netsh int ip reset and press Enter.
- Type netsh winsock reset and press Enter.
- 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!

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.
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.
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.
Unfortunately, as the Killer Wireless-AC 1550 only has Windows 10 drivers, this workaround will not work for the 1550.

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
If you encounter an error when installing the .INF drivers for a wireless adapter, you may need to enable wireless networking in your Windows Server. This applies to all Windows Server editions, 2008 and beyond. To do this:
- Access Powershell from your administrator account
- Type Install-WindowsFeature -Name Wireless-Networking and press Enter. You should receive a confirmation that the service is installed, and a warning that the machine needs to be restarted.
- Type Restart-Computer to restart.
- Once the machine has restarted, access Powershell from your administrator account again.
- Type net start wlansvc to start the wireless networking service.
- The .INF drivers should now install normally.
The Killer Control Center is not availalbe on Windows Server editions.

Most Killer Networking adapters work well with most Linux kernels without the need for any troubleshooting or setup. As there are many Linux distributions, and many variations of those distributions, some users may run into issues with compatibility and their networking adapter.
These are the drivers used by our networking adapters:
- Killer Wireless-N - https://wireless.wiki.kernel.org/en/users/drivers/ath9k
- Killer Wireless-AC 1525 1435 and 1535 - https://wireless.wiki.kernel.org/en/users/drivers/ath10k
- Killer Wireless-AC 1550 series (only currently supported in the very latest Linux kernels) - https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
- Killer E2200 E2400 E2500 Ethernet - https://wiki.linuxfoundation.org/networking/alx
With the exception Killer Wireless-AC 1550 series, the drivers for all of our devices are community developed and supported. We neither develop nor support the Linux drivers for our devices, and this is common, as free and open source is the Linux way.
As such, if you encounter an issue with your Killer Networking adapter in Linux, your best, quickest, and most accurate line of support is going to be the community, either for the Linux distribution that you are using, or the driver itself. Our knowledge base contains some limited known information. These are things which we have discovered and posted in order to hopefully make things easier on our users. However, most problems will be specific to either the driver, the distribution, or even the version of the distribution that you are using.

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.
Please note that Windows 8.1 or 10 is required on the Killer enabled device for the router to label it as such in the router's interface. The router will still prioritize the Windows 7 Killer enabled device, but it will not appear that way in the router interface.
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.
Consoles will not appear as Killer Enabled Devices, even on the WRT32XB. The unlike the WRT32X, however, the WRT32XB will identify the XBOX ONE by name. You can then assign it priority within the router's UI.
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.
