Here's the deal: I've had a desktop that has been working just fine with my cable modem. I just bought a new laptop with a wireless card. I then bought a Belkin wireless router and set it up. Both my desktop and my laptop are surfing the Internet just fine. Both computers use other IP programs like AIM and FTP just fine. To me, it seems like TCP/IP is working OK. Well, I have been unable to share files between the 2 computers, so I started checking out the IP stuff. What I've noticed is this: 1. The wireless laptop can ping the router OK. 2. The wired desktop gets "Request Timed Out" 3. When I plug the laptop into the router, the laptop can ping the router OK. Since the laptop plugged in works fine, it seems to be a problem with the desktop. I've disabled the Windows firewall. I don't know what it could be. I mean, if TCP/IP were messed up, how am I using the Internet through the router? Any ideas what could be causing me to be unable to ping the router from my desktop?
