I bought a refurbished HP desktop computer. When i booted it up i couldn't find any wireless networks. upon further investigation i discovered that only dial up and broadband were offered. I sent it back and bought a comparable acer. i love it but i hate win 10 so I installed win 7 pro. When I booted up guess what? same thing! However in this case i had wifi when win 10 was installed. anyone else heard of this and if so is there a fix?
