MCE 2005 can't ping anything on network other than router and itself

I have a bunch of computers networked with a Belkin N1 router. My MCE laptop is a problem child. The other machines can see each other on the network, but this machine can't. It can ping the router, ping itself, but can't see anything else. I've turned off the firewall, but that doesn't help. Anyone know what might be wrong?

"ipconfig /all"

check your DNS, gateway, etc.

"netsh winsock reset"

resets your TCP/IP, fixes most lsp problems, which may be the cause of yours.

When you ping your router, does it show the correct address in "pinging 192.168.1.1" or does it have gibberish instead of the IP?

are your other PCs behind firewalls?
