3Com 3C905C-TX-M 10/100Mbps Etherlink PCI NIC

Works as expected with 91% TCP transmission throughput. Card was clean.

I got this particular NIC because I needed this specific make and model for device driver testing. The NIC works well, but its only 100 Mbps and probably no less expensive than other good gigabit and newer 100 Mbps units. I wouldn't normally recommend this for new computers. But if you need a 3com NIC, this model works, and is supported by pretty much all of the operating systems.

When my vintage (circa 2001) desktop stopped talking to the router, I decided the NIC PCI cardmust be defective. I had two older (from the last century) computers in the attic from which Icould pirate a card but they might be a different make or model. If I used one of those, Imight need to change the settings on my network software. I didn't want to gamble a lot of timeor money so I chose a $0.40 used card of the same make and model as the one that came in myDell Dimension 4100. Shipping was under $5.00 and the company had a 93% approval rating. Well,I got the used card, opened the box (Dell) and popped in the card. When I plugged it in andturned it on, it booted (of course) so I could log on and connect to the internet or my LAN.It was just that easy.

Fast shipping and it was exactly what I ordered and needed. Thanks!!

This card will not operate under any version of Windows Server, and per 3Com is not supposed to work under Windows XP (though one is working on my XP box). Outdated garbage. Should be tossed out, not sold to unsuspecting buyers.

great for old systems!
