Everyone at uni who thinks they know something about computers has tried to set up my wirless connection at uni, but to no success. The last guy changed something on my Firefox and now I cant use it! I'm currently using IE....it's killing me!! The error I get when trying to use Firefox is:

Network Timeout

The server at forum.classicamiga.com is taking too long to respond.

The requested site did not respond to a connection request and the browser has stopped waiting for a reply.

* Could the server be experiencing high demand or a temporary outage? Try
again later.
* Are you unable to browse other sites? Check the computer's
network connection.
* Is your computer or network protected by a firewall or proxy? Incorrect
settings can interfere with Web browsing.
* Still having trouble? Consult your network administrator or Internet provider for
assistance.

Where are the settings to fix this??
