I just recently acquire a computer that had windows on it, and the wireless worked fine. I installed Ubuntu, removing windows. Having started it for the first time, I find that I am unable to connect to the wireless. If I ping, for instance, google it says "ping: unknown host google.com". If I try the ip address, i get "connect: Network is unreachable" I tried reinstalling, and it still has the same problem. Any ideas? All the other devices on my network can connect. Any ideas? Ps. I'm a bit of a noob, so please keep the language simple. Thanks!
I use wpa2-psk
