I have moved my PC from one radio network (Proxy server) to a home network using ADSL wireless router.

Anyway, I managed to get my radio card working and opened up the Mozilla browser. This was odd as all the default toolbar folder sites would open up and I could go from page to page, but I couldn't access any websites by typing in the address - not even google. These sites all timed out.

I tried another browser - Konqueror, and this worked on all sites but was slow. I think that my radio signal is weak, but how can I access some sites, but nothing 'outside' the bookmarks?

Incidentally, I was actually online as I accessed 'latest news' links and read info only a week or two old.

Firewall is turned off.

Well, your either browsing your cache, or your dns has gone down, more than likely a bit of both though
