This problem happened to me too . . ."no wireless device",
u can try install and uninstall the driver (but fot me it didint work)
for me, the solution is very simple, u just go to the acer website and download a new bios for ur pc . . my problem was caused by the bios not compatible with the driver . . at the acer driver download site u can choose a variety bios. Install it, and walla! ur wireless is alive again.
A big thank you!!
Your suggestion worked!
By the way how did you figure out that it was problem related to BIOS? Because I had not thought in that direction even once..
