I bought the 3Com EtherLink 10/100 Mbps PCI Network Interface Card (Model No. 3c905c-tx-m) and it not only did not work on my system (Duron 700 with Asus A7V motherboard), but it then caused my original 3Com card to stop working correctly. With the new 3Com card, I could not even access the internet through my Linksys 4 port router using DHCP. When I returned the original 3Com card to the system, I could at least access the net, but I could no longer browse newsgroups, and the internet games I play seemed to slow down (this could just be in my mind, but Asheron's call seems to be logging out and in very slowly, and others that play said that they have not noticed any change lately)...
I tried many times to get the new card to work (uninstall, then reinstall, uninstall in save mode, then reinstall, uninstall dail-up networking [who knows? maybe this would do something?] then reinstall, try all of the above after running pre-installation program on 3Com Cd included with card), and then many times to restore the original card back to proper working condition (see list above, and note that registry seems to still have listing for pre-install program), but to no avail. Still no internet connection with new card, and no newsgroup connection with old when set for DHCP server with Linksys router. The frustrating thing is that all the other computers on my network still worked, so the problem does not seem to be with the Linksys router. Something changed with my Duron.
The one thing I noticed that changed in Network Neighborhood (Win 98 SE, did I mention that?) is that the TCP/IP protocol no longer says the name of my ethernet card (regardless of the new one or old one). It used to say something like, "TCP/IP Bound to 3COM 3C905" (or something like that), and now it just lists TCP/IP. The ethernet cards themselves do in fact say that they our bound to the TCP/IP, but there is no listing under the TCP/IP protocol itself. I don't know if this is telling as to what is wrong, but if anyone has any idea, I'd appreciate the help in trouble shooting this.

I bought a 3Com card because I was very happy with my original one that I've had for the last two years. It felt like a work-horse, and never had any problems. I bought a new one because I wanted to use the Wake On Lan feature of the motherboard so I could have my computer on all the time, but keep it basically off unless I accessed my ftp site (then it would theoretically wake up, magic!). This has been very frustrating, and a search of their site has resulted in no leads on how to fix this problem. I tried to call their customer support, only to recieve a message that I should call between 8 and 6 (it was about 2pm on Sat, so I guess they mean weekdays). Unfortunately, I am in the video game business and don't usually make it home anywhere near 6pm...

Any ideas? Would very much appreciate any insights into my problem. By the way, the cable router is connected to a cable modem, but like I said, the other computers on the network are still working fine. I did eventually play around with asigning static IP addresses to all the computers, but that did not change anything, so I went back to running the router as a DHCP server.
