network card problem

Jon Miller-5
Recently I had to replace a motherboard and 2 network card due to a static discharge in a rack.  I've now have 2 networks cards in the server and they load ok, both can be seen with lspci.  The interrupts are not being shared or anything of the sort.  Yet one of the cards (Netgear FA311) will not respond to a ping.  This the is tests that I've done.
1) connect a  cable from the FA311 to a hub, put my workstation on the hub and the Cisco 2821 router's gigabit interface on the same hub.
 from there I  ping the router - that was good, ping the gateway server with the FA311 (no reply, times out).
2) from the router I was able to ping the workstation yet when pinging the gateway server again times out and no reply.

Had a look at the interrupt the card is on irq19 whereas the other card is on irq 16.
I've unloaded the driver and reloaded it and still nothing and no errors when it loads.

Can anyone suggest any test or a fix that may help in resolving this issue?

Summary:
Gateway server Debian 3.x
eth0 - Netgear FA311* *fa3xx.o (notice that it states that it is running a half duplex if this helps)
eth1 - Realtek 8129

a crossover cable connects the gateway server (eth0 192.168.100.2) to the Cisco 2821 router (gigaethernet0/0 192.168.100.1), whereas the other nic (eth1) connects to a Cisco 2950 switch.

Thanks

probably mii-tool will tell you something about the card.
ifconfig -a reports any nic errors?
run tcpdump -n -i <interface_name> to see what hapens.

Also, if you are using a hub try to "force" all things attached to the
hub to "10mb half" (no autonegotiate).
