USB Wifi Connection trouble... also ethernet problem

[XA04]

OK, I decided to install Ubuntu on my laptop last night. Basically I have a wireless USB stick, it appears linux can find it, and can find my wireless station (brings the SSID up), I enter my passkey... and it doesn't seem to connect (I don't think... I can't access the network or internet anyway). I'm 100% sure I'm using the correct pass key.

Any ideas on what is wrong?


My other problem... decided to use the ethernet cable after I gave up with the wifi, it connects to the network fine - but it doesn't connect to the internet (whilst other computers on the network can).

Any ideas?



I'm a bit of a linux noob so any help is appreicated,
Thanks

Also, another thing. This latest version of Ubuntu, it doesn't bloody ask for a root password so I can't login as root now :\
