Well we have a network here at home but no other pc's work on the internet apart from this one, but I can connect into this pc from all the other pc's so that means the network is working. What the hell is wrong how can all the computers not work apart from this, is it the router? I will be kicked of this in a min and have no pc all day lol

Have you ran the network wizard on the other pc's?

What result do you get when you do a tracert to some website from the PCs that can´t reach the internet ? Whats is the last hop ?

How do we do that? I have just been able to get on to here but using IE and not firefox. I only got on because I turned the router off and on. We have had no problems with connection at all for over a year now suddenly none of us can connect or if a miracle happens one of us a a time. I initially thought it was an ISP problem but their status is set to okay. It must be a router problem but we don't know how to access the settings.

EDIT: The router won't let us in to the settings at all.

Fixed It was because we had the main routers dns server set as my old pc which had broken and nolonger online but now set it to this pc and its faster than ever
