Could someone please help me ? I have made a complete mess of my network connection settings . I was just messing about with a proxy ip that someone on youtube gave me . I have now lost all my original internet connection settings and Im stuck with a proxy i.p from that wont allow me to connect to the internet . Is there anyone out there who could tell me how to restore my default connection settings ? I am using a macbook on osx 10.5.5 and I was using an old ntl ambit 250 modem and have never had any problems . Until now that is !! I have been looking for a way to fix this for over a week with no luck . Any help would be greatly appreciated .
