Ping-tracert returns only time outs yet TCP/IP functions fine

I have an ME system on a home net (192.168.0.53 255.255.255.0) It's
gateway is 192.168.0.1 which is a LinSys router connected to a
broadband cable modem. I cannot ping this machine from any other on my
home net nor can I ping anything (local or Internet IP address) from
this machine. Yet all browser functionality is working fine. I can put
a sniffer on the hub to which it connects and see that TCP/IP to the
Internet is working, connecting to a shared directory (via NetBios
over TCP) works fine, using a net use * \\othermachine\share command.
Yet when I attempt a tracert or ping, no ICMP packets ever appear. It
is as though they are being blocked and never hitting the wire. I have
been using Panda Anti-Virus Platinum 7.0 with a built-in firewall and
thought that have been the culprit but disabling that has made no
difference, nor has been ripping out the TCP stack completely and
re-installing. I also replaced the original NIC with an Intel
EtherExpress PRO card with no change in the symptoms.

This is driving me nuts. Anyone have any suggestions or ideas for me?

I'd suggest uninstalling (not disabling) the firewall.
