I have a Dell desktop computer running XP Pro, with no wireless card, and I connected a Linksys Wireless-N home router to this computer via ethernet cord.
After some grief with limited or no connectivity, I manually entered the IP address, gateway, and preferred DNS server. The taskbar notification balloons tell me that I'm connected and the signal strength is very good, but when I open the Internet or Firefox, the page cannot be displayed.
I've made sure "work offline" isn't checked, and I've tried disabling the firewall. I've cleared cookies, temp files, history, etc. to no avail.I've reset and disconnected the router, checked cables, and still no luck.
I then opened up the dos prompt and tried pinging the router. I got the response that the request timed out, and 0 of 4 packets were received (100% loss). I tried pinging yahoo.com and google.com, and was told that the host could not be found.
The laptop I'm currently using works fine and it's part of the same network. I'm out of ideas - any suggestions would be great.
