In checking on the NIC, I notice it is described at several sites as having both BNC (thinnet, 10Base2) and RJ45 (UTP, 10BaseT) jacks. And I notice that after you ping unsuccessfully, ifconfig reports (in part)
TX packets:9 errors:0 dropped:0 overruns:0 carrier:9
Taken together, this makes me wonder if the card is set to use the wrong port. The docs I found for this card seem to say it comes out of the box set for media autoselect, but that's not something I'd rely on. The "Destination Host Unreachable" message you get when ping'ing is consistent with this guess (though not always present). You might want to get the DOS-based setup program for this NIC (or see if Don Becker's released a Linux-based one) and check its settings.
And I realize, in rereading your message, that either you've not said whether you are using thinnet or UTP with this card, or I missed where you told us. Also, just barely conceivably, you've connected it via UTP to a switch that does not drop back to 10 Mbps (is the other card you test with successfully 10 or 100 Mbps?).
Final thought ... I have a hazy memory of running into some oddball 3Com NICs of about the vintage of the one you have. They had problems with standard UTP wiring. I forget the details ... except that I ended up scrapping the cards, NICs these days being too cheap to spend much time mucking about with (especially old, 10 Mbps NICs).

This was the bare.i kernel, 2.4.20, default install.. The module was loaded and the NIC card found automatically on boot; the only entries I made were ifconfig and route add.. See following script.

See following script, some snipped to shorten the verbiage. Only one NIC at a time..

As I read man mii-tool, I gather it's for RJ45 connections only whereas I'm exclusively thinnet, 10base2, BNC.. Correct me if I'm wrong on this..

Back to 3Com NIC and a repeat of the problem.. Hopefully you can see something I'm not familiar with. <grin> Thanks Richard. ------------------------------------------------------------------------------
