Internet Problem

[leonmagic]

I've got 2 computers in my house, both connected to the Internet with the Telstra Wireless Broadband deal.

My computer (the main one) says it cannot establish a connection to the internet, yet my sister's (the secondary one in the next room) can connect (hence me writing now) yet it reads off mine...

Can anyone offer advice, or even work this out???

And yes I've run both Anti-Virus and Adaware programs, but still no dice.

check your connections tab in IE under Tools-> Internet Options. It may be asking you to connect to an old setting

what sort of network are you running between the two computers.

do you have xp on both computers?

as a wireless connection do you have the appropriate hardware from the modem, router and wireless connections on both pcs?
