Question : Wireless can't ping router but wired can

So, I have a D-Link DI713P router.
OS is WinXP Home

My wired computer can connect to the router, connect to outside websites and works perfectly.

The wireless computer gets assigned an IP but can't ping the router, connect to the router or connect to any outside IP.

I've played with the MAC filtering and had the router assigned a static IP address to the wireless NIC's MAC address and it worked fine.  The router sees the wireless NIC and I can surmise that the wireless NIC sees the router just fine.

When I look at the connection status I see that the NIC is sending packets out just fine, its just not gettimg them back.

After being connected for 13 minutes I see that Ive got 636 paackets and only recieved 1.

The connection strength is excellent and when I have the router off instead of pings timing out the hosts become unreachable.  Im absolutley stumped as to why I can't get this to work.

Is there a hardware failure inside of the router, or is there some stting that Ive got goofed up?

I have WEP turned off and all of the settings apart from mac filtering are defaulted.

Ugh :(

Answer : Wireless can't ping router but wired can

Well, as far as i see, the configuration is correct, and what makes me belive that this is a hardware problem more is that the same configuration on both computers and one work and the others dont.. so for sure this is a hardware fault.
