3com NIC not connecting on Ubuntu

Ubuntu installed fine, I think, however I can't connect to the LAN, even though I'm using a common 3Com Ethernet card. What's more Windows and Suse Linux 9.1 which I tried previously worked fine on the same machine.

I think the problem might be that the network card (3Com 3c900) has 2 interfaces, a 10base2 coax BNC connector as well as a more usual 10baseT. I'm using the BNC connector.

Windows works fine, and I managed to get the Suse Linux drivers to work by altering a config file to force the card to use the BNC connector.

But I can't find out how to configure device drivers under Ubuntu (Debian based). Searched everywhere.

Doesn't help that feedback I've seen for others with driver problems says do things like Ismod. Well on my system if I do an Ismod, even logged in as root, just says 'command not found'. Is Debian / Ubuntu so different form other Linux distros.

Thanks in advance.

That's because it isn't "Ismod", it is "lsmod" -- a lowercase letter 'L'

Try it again and see what you get.

Doh - I need new eyes. Smack up the head.

So yes I can see I do have a 3c59x module listed which should be drivers for my 3com 3c900 card according this this website (which seems to be the author of the drivers).

So where in the boot process is this configured? I recalled under Suze I could just change a small config file somewhere that forced the interface to use media type 3 (the BNC connector).

Thanks again

I'm trying to do this very same thing.. I can ping fine if using RJ45, but no luck on the BNC.. Anyone know how to make this work?
