A Blue Screen crash is present with a Killer-N Wireless device installed on a machine running Virtualbox
Before using VirtualBox, open the Killer Network Manager, click on the Advanced tab, and set "Application Control" to "Disabled." This should prevent the error from occuring.

iTunes won't connect
You need to update your Killer software, found on the Downloads page of the Support section. A successful update will remedy connectivity errors with iTunes and other Apple software.
LSP not mapped correctly
This message is usually brought on by one of two things: either security software is blocking the installation of the LSPs, or a third-party program is installing its own LSPs, which prevent the Killer's from installing.
First, if you are running antivirus/antimalware, please try reinstalling the Killer drivers with your security software disabled. This may fix your issue.
If you do not run any security software, please do the following so we can determine what might be the cause of the conflict:
Click:
Start > All Programs > Bigfoot Networks > Killer Network Manager > System Diagnose Utility
This will generate a diagnostic text file. Please save the file and attach it to an email to support@bigfootnetworks.com along with a description of your issue.
Unable to establish a connection with the QQ Chat application
After opening QQ Chat, from the "Applications" tab of the Killer Network Manager, click on the QQ Chat process. Switch the priority from 1 to either 2, 3, or 4. This will allow the application to connect as normal.
USB devices plugged into the USB port on the Killer Xeno Pro do not function
This behavior is by design. The USB port on the Killer NIC is only accessible from FNApps that run on the card itself. The only physical connection accessible from Windows is the RJ-45 network port.
You receive the error message 1603 on installation of Killer software
First, download and save this cleaner:
Then, uninstall your current Killer Network Manager software via Control Panel > Programs and Features. Reboot.
Then, run the cleaner. Reboot once more.
Make sure to disable any antivirus or antimalware software, and reinstall the Killer drivers. If the problem persists, please contact technical support.
