Can't install drivers for wireless

[-EvilGrin-]

Hi! I'm new to linux, and I usually like to solve problems on my own, but can't get over this. I installed all regular updates etc... and I noticed I can't use my wireless, but have to use cable, so I oppened hardware drivers "thing" and updated graphic card drivers (that went fine) but when I try to install wireless, system freezes and stay that way until I reboot. When I start system again, its unusable can't boot up and I had to re install ubuntu (did that few tymes allways same result). I'm wondering if there's some known solution to this issue.

Thx in advance.
