Question 1

Install fails or rolls back?

Accepted Answer

Uninstall any existing Killer Wireless/Bluetooth driver and Killer Control Center, reboot, then run the 1535 installer as administrator. Avoid installing over a partially removed package.

Question 2

Device not detected?

Accepted Answer

Check Device Manager for an unknown network controller. Reseat the M.2 card, enable wireless in BIOS, disable Airplane Mode, and show hidden devices if the adapter is missing.

Question 3

Version conflicts?

Accepted Answer

Remove duplicate or older Killer/Qualcomm drivers, roll back if a Windows update broke connectivity, and install only one package matched to your Windows build—don’t mix a standalone INF with the full Killer suite.
