Help getting Gigabit Ethernet PCI Adapter to work

Experts,

On another thread, my dear experts suggested I upgrade my router, which I did.  While at the store, the salesman said I really needed a Gigabit Ethernet PCI Adapter.  It was only $25 so I bought it and can't get it to work.  Netgear says it's my computer and not their card, so I'm hoping you guys can help me get this to work.

I've tried:
   - Unplugging everything and restarting.
   - Turning off the firewall
   - Taking the router out of the equation
   - Statically defining IP,Sub,def,DNS
   - Turning off the firewall
   - Disable my motherboard ethernet

I go to "Network Connections", in XP, and both my motherboard ethernet and the new card say "Connected".  But I still can't get on the internet through the new card.

Your help is greatly appreciated, as always.

After connected your Gigabit Ethernet PCI Adapter you need to install the drivers of that card. Did you installed the drivers. If you installed the drivers then Set the IP addresses on pc and also on router with same class.

Backing up a bit, unless there is something you've left out, it sounds like bogus info from the salesman. If your intent is to improve your internet connectivity, there would be no benefit of a gigabit ethernet adapter over a standard "fast" ethernet connection.
Gigabit = 1 Gb/sec = 1,000 Mb/sec
Fast ethernet = 100 Mb/sec
Typical internet connection speed ranges from 1.5 Mb/sec up to around 20 Mb/sec

Even if the gigabit adapter was purchased with the intent to speed up network file transfers, the non-gigabit interface on your computer's motherboard suggests strongly that its age or build quality would be the limiting factors, again making little to no difference in network performance whether on gigabit or fast ethernet.

In "Device Manager", everything is working correctly.

Schaps, so maybe I don't even need the card?

If all you are looking to speed up is the Internet, you'll see no difference. If you are looking to speed up file transfers on your local network, you might see some small benefit, as long as the other devices are also gigabit. But with a P4, I doubt you'll see any much of any difference except time lost with this darn pain in the neck troubleshooting, so it's a waste of time and money.
Take 'er back.
If you do get it working and decide to keep it, you can quite easily set up some tests switching between your two ethernet ports to confirm my theory.
