I just installed Kubuntu 12.04.2 and do not have an internet connection.

I also cannot access the Desktop and only have the terminal. When I enter xlcock I get Error: Can't open display:. I believe this is because I do not have the correct drivers and need to download them ... using the internet which I can't access.

So here's what's going on ... ifconfig gives:

lspci -nnk gives:

I believe this means that it is using the ethernet connection but thinks it is a wireless connection.

sudo lshw -class network gives:

I want to get the internet working so I can fix the GPU driver, etc. but I can't seem to get it working even though I have my ethernet cable plugged in (and I'm sure it is working).
