Well, I finally got to put in the new card. It is a Linksys. I'm running the cable modem through the onboard NIC. I set it down to half duplex 10 and this is a typical test tonight. My wife's comp is getting net access through the new NIC on mine and she maintains 4K+ downloads almost everytime and I haven't even tweaked hers. That tells me the speed is there, but this machine evidently doesn't like the XP SP2 5000/384 cablenut settings for some reason.

Thanks in advance for helping me with this.
