ok, i just got a new router, (wireless, to replace old wired router)and quickly got it setup to access the internet. everything working properly on 2 of 3 computers, i dont bother with the third, which happens to be my mothers, but she now cannot access the internet. her computer hooks up with the router and everything just fine, gets its own unique ip address, but it doesnt matter if i have it on wireless, or wired network connection, hers just refuses to accest the internet (access is refused error in firefox) it is the D-Link DL-524 router, and all computers are running windows xp home edition. comp a- connects via wirelss connection and works fine comp b- connects via wired, and wireless connection, works fine comp c- connects via wired, and wireless connection, connects to router properly, gets ip address assigned, can access router setup page, connection is always refused for anything to do with the internet. doesnt matter what port i plug it into on the router. anyone have any ideas on what the problem might be, and how i might go about solving it?
