I recently installed ubuntu on my HP 4330s laptop. Well everything works fine, except for the wireless network. I can't seem to get it to work. Plus the button you could press to turn wireless networking on and off in Windows have changed to a switch for bluetooth. I've look for network drivers, but I can only find it for other linux. I dunno if the driver is causing those problems, but It's worth a try.
The driver I'm looking for is RaLink RT3592.
Btw, connecting to internet trough a cable works.
