How Do I Use The Killer Prioritization Engine In The WRT32X?


Thank you for your email.

In order to use the Killer Prioritization Engine, you must be using a PC with a Killer network adapter installed, running the latest Killer Control Center. Killer network adapters come preinstalled in many gaming laptops and mainboards, and are not available for sale separately. 

Consoles cannot make use of the Killer Prioritization Engine, or the Killer Control Center, but they can be prioritized in the router's interface. 

For further support on other features of the WRT32X, please contact Linksys support. 

Killer Network Adapters and KRACK Exploit


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 (, and the operating system is the primary key handling layer.

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.

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.

Buying and Installing Killer Network Adapters


Buying and Installing Killer Network Adapters

Unfortunately, our current line of network adapters are currently only integrated into motherboards and laptops of various manufacturers and not sold as individual units. This is due to different regulatory and system calibration requirements. We apologize for the inconvenience.

You may find that our wireless adapters do show up online for sale from time to time. These are not authorized for resale by us, or any authorized manufacturer, but are being sold as components removed from other machines. Be sure to keep that in mind when purchasing. We can only support adapters that are obtained in this fashion in a very limited capacity.

Also note that many laptop manufacturers use hardware IDs to lock out non-authorized Wi-Fi adapters, so swapping in another adapter may not be as simple as it seems.


Will the Killer Prioritization Engine in the WRT32X Help Consoles?


Will the Killer Prioritization Engine in the Linksys WRT32X Help Consoles?

No, but it won’t hinder them, either. The Linksys WRT32X is an otherwise fully featured router, which also includes the ability to work with the Killer Control Center’s network prioritization features, and thus requires that any machine using this feature use a Killer Network Adapter. The router also features the ability to prioritize non-Killer devices using three levels – default, low priority, and high priority.

You can learn more about the router on Linksys’s website here -


The Killer Control Center versus The Killer Network Manager


The Killer Control Center versus The Killer Network Manager

The Killer Network Manager is our older, outgoing network prioritization suite.

The Killer Control Center is much more optimized for current builds of Windows 10, and even some security changes to older versions of Windows, and will be the only performance suite that will be updated going forward.

As Microsoft continues to make changes to their operating system, the Killer Network Manager will become less usable. We recommend all users switch to the Killer Control Center as soon as possible, regardless of which software their machine originally shipped. The best course of action is to download the latest Killer Control Center, found here - - then, in your Apps and Features menu, uninstall any Killer Drivers or Killer Performance Suite entries that you see, restart your machine, and then run the installer for the Killer Control Center. If you encounter any issues, you can contact support at


Do I Need The Killer Control Center?


Do I Need the Killer Control Center?

The Killer Control Center is the program that examines your applications, and sets priority so that your most speed-critical applications get first access to your bandwidth. Without it, every application that uses your Internet connection gets equal treatment, which can cause noticeably slower speeds.

For example, say you are playing a data-intensive game, also streaming a YouTube video, and downloading a large file. Without the Killer Control Center, your game might have issues as it has to share its bandwidth equally. With the Killer Control Center, the game will be given all the bandwidth it wants, while the video is slowed (which just means it'll likely buffer a bit more to start, and then work perfectly), and your download is the lowest priority.

Will the adapter work without the Control Center, running only the .INF version of the drivers? Certainly, but you are missing out on its most important features!

In summary, if you want to make the most of your Internet connection, you will want to use the Killer Control Center.

Do Killer Network Adapters Support Link Aggregation/NIC Teaming?


FAQ: Do Killer Network Adapters Support Link Aggregation/NIC Teaming?

Link Aggregation is not supported with any Windows consumer platform. In order to use Link Aggregation, you must be using an Enterprise grade router with this capability, and a Windows Server Operating System. However, the Killer Control Center is capable of using multiple Killer Network Adapters at one time with Doubleshot Pro and Doubleshot-X3 Pro which, for gaming, is even better than Link Aggregation, as the Killer Control Center can make use of Wi-Fi and Ethernet at the same time!

Resetting Your Network Stack: An Explanation

Some users have requested an explanation as to why they should reset their network stack. They want to know what the commands do, and that's great! We love users that want to understand how stuff works. Following is each command in the Windows stack reset, and an explanation of what it does. At the bottom of the article, you can find references for terminology, and further reading. 
netsh winsock reset resets the Winsock protocol, which is what Windows uses to interface with the TCP/IP stack. There are very few ways to manually configure this, yet it is possible for it to get corrupted, so resetting it is always a good first bet. This can solve issues that prevent a machine connecting to a router.
netsh int ip reset resets your machine's TCP/IP settings. TCP/IP is the standard your machine uses to connect to any other machine, locally or on the Internet. These settings are usually fairly generic, so resetting them is harmless, but if they are corrupted, it can cause problems, such as inability to connect to certain routers.
ipconfig /release tells your computer to release the IP (Internet Position Address) it is currently using, and also instructs the router to disassociate the IP with your machine. If the router has any hung resources connected to the IP, this can free them up. 
ipconfig /renew is necessary to regain an IP after the previous command. You could accomplish the same thing by restarting the machine, but some routers seem to prefer this method, and will not hand out an IP otherwise.
ipconfig /flushdns clears out your DNS cache. DNS = Domain Name Server. DNS is how computers turn names into numbers -- web addresses into IP addresses. When you type into your browser and press Enter, your computer actually accesses a sort of phone book (DNS server), looks up the IP address for, then navigates to that IP address. It will then cache this information so that it doesn't have to spend the time looking it up next time - it will just go straight to that IP address, without touching the DNS server. If, somehow, this information is wrong (websites move and cache files get corrupted) clearing this cache can be helpful. Worst case scenario, it runs microseconds slower because it has to look up and re-cache those DNS addresses again. In days past, this delay was far more noticeable than now.
