I have this RT3290 wireless thing in the laptop I use ubuntu on. It took me a while to get working by compiling source I downloaded from some where I forget.
Will be doing a clean install soon and am not looking forward to wrangling this problem again, any one running a linux distro with this wireless driver without problems?
Also, out of interest, I did run 14.10 ubuntu gnome off a usb disk and found that the kernel it uses, 3.16, seemed to recognise the wireless card and was able to use it fine. It might be time I update.
