Hello mpw101
As I understand it you have an HP Pavilion p6-2220t CTO Desktop PC and are running the Ralink SP62055.exe? I have no idea why the Support Assistant would recommend that update as it is for Business model computers and not for your computer. I would recommend that you follow the instructions below.
Step 1. Download this driver for your computer
Step 2. Go into the Device Manager
Step 3. Right click on the Ralink Wireless and Uninstall it (ensure to remove the driver when prompted)
Step 4. Double click on the file you downloaded and install it as it is the correct Ralink driver for your computer
This should resolve your issue. Thank you for posting on the HP Forums. Have a great day!
