Some users may experience issues with their Killer Networking adapter on older versions of popular Linux kernels.
You will first need to install the latest backports package to have up to date drivers.
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_1.169.3_all.deb sudo dpkg -i linux-firmware*.deb sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci
The 1535, 1525, and 1435 use the community developed and supported ath10k driver. Killer Networking neither develops nor supports the ath10k driver. For further support, please refer either to the community support for your specific Linux distribution and version, or the driver itself.
The Killer Wireless 1550 only works with the latest Linux kernels, using the iwlwifi drivers and firmware. If the kernel does not have a recent iwlwifi driver, it may not include the hardware ID for the 1500. Refer to the support for your specific Linux distribution and version for further support.
