I switched my computer over to Ubuntu from Windows, big mistake. I cant get my wireless to work. I scan wlan0 and a bunch of other things that I copied and pasted from the internet. I have no idea if my wireless card is working or not? I tried to manually create the connection by typing in my routers ssid and wpa2 key, the little wireless icon in the upper right looked like it was looking for the router.

No matter what I scan for in the terminal I get interface does not support scanning. any advice?

  • Get to software sources, additional drivers tab. Can you see and activate the driver there?
