Cannot ping, cannot surf using Linksys wireless router.

Hi all,
I have a home wireless network setup with BEFW11S4 Linksys router. I
have an inbuilt Intel PRO wireless NIC and am running Win XP. Well
here's the problem...
As soon as I start my computer, it automatically detects the wireless
connection, an IP address is assigned and the wireless connection is
active. However in the Wireless connection status it shows that the
connection is able to send the packets (since this number keeps
increasing) but is not able to receive any packets (this number stays
zero). Hence no connection to internet.

I tried to make the IP address static. Still the same problem. Removed
zonealarm firewall, removed Cisco VPN client (used for wireless access
in school),tried release/renew of IP address. Still no luck.

Am able to ping localhost. Not able to ping the wireless router. The
wireless router configuration shows my wireless connection as active.

And lastly, few days ago my connection was working fine until one
morning all hell broke loose. (My roommate's wireless connection still
works great with the same router, ofcourse.)

Any ideas will be really helpful.
Thanks a lot,
-V

At the LinkSys router end, have you enabled MAC filtering and checked
the box? Checking the box next to a MAC blocks connection with this
router, leaving it blank allows only that connection. On the laptop
end, has 802.11x Authentication somehow been enabled? Or the XP
firewall? Is the preferred connection selected in the wireless? Are
there contending wireless networks available? Do you have a wireless
phone or base station nearby? Does the wireless adapter have an antenna
connection that has become detached? If you disable wireless zero
configuration and set up manually, can you get a connection? You could
try to fill out the NIC properties, even if using WZC.

From Duane Arnold on another thread concerning possible broken TCP/IP
stack [this might be a possibility since the wireless suddenly quit]

To rebuilt the stack:

1) Use Regedit in the Start\Run Box
2) HKEY_Local_Machine\System\CurrentControlSet\Servic es
3) delete the Winsock and Winsock2 entries
4) NIC's Properties Box delete everything out of the box.
5) Reboot the machine which will rebuild the stack
6) put everything back in the NIC's Properties Box
