Linksys wireless 403 error

Hi
I'ved just hooked up a Linksys WAG54G router adsl modem. I'm using it to
allow access to the internet and other files between my laptop and a PC
upstairs.
My laptop is working fine but my PC upstairs cannot view web pages. It
keeps giving me a 403 error. I can still access the internet through P2P no
problem and access the files on the laptop but no web pages are viewable.
I'm using BTYahoo as my ISP (if that's any help) and there are no
restrictions in the router settings that I can see.

Any help please

TIA

George

403 is access denied, so it's probably a proxy setting that's wrong if
you get it on all sites.
