I have been looking around google and this site for ways to connect to the internet, I found what I thought was useful information but was never able to try it at my college because we use Cisco (oh how I hate cisco). So now I'm home and tried the commands

/etc/init.d/networking start

and

/etc/init.d/wicd start

From what I found online I think that this should make both wireless and ethernet work, right? Well, after typing these in I tried to open the internet while connected with the ethernet, and all I got was just a long loading screen and then and error on firefox saying unable to connect. Do I have the commands right? Am I missing something? The internet works fine in windows. I should say that I am booting from a persistant usb, I don't know if that makes a difference or not, I hope not. Any ideas?
