Whenever a beginner describes an impossible scenario, my first guess is that
the description is inaccurate or incomplete.
Is it possible that both cards were being recognized by the kernel (or by
modules) and your actual network was set up to run on the 3Com NIC as eth1?
Then removing the NE2000 card caused the 3Com to drop down to eth0, and all
your networking scripts were wrong. What NIC-related messages show up during
the boot sequence?
Is it possible that removing the NE2000 card somehow affected PnP behavior
in the BIOS? Since 3Com modules autoprobe, a move of that card would not
have affected the module's ability to find it. But you say that "packets
were being sent out, but not received" on the 3Com (how do you know, BTW?),
and that suggests an IRQ problem of some sort.
I could offer other wild guesses, but that's all they would be. Expertise
needs information to which it can be applied, and you haven't supplied the
needed level of detail.
If you really are curious, give us a real shot at this one by telling us the
following:
1. output of "ifconfig -a"
2. output of "route -n" I bet you do have static routing
in place - it doesn't require routed or gated)
3. contents of /proc/interrupts
Do the above three both ways -- with the NE2000 in and out.
4. contents of /etc/modules
5. what Linux distribution and version you are using.
6. whether the NICs are isa or pci, and whether they are PnP.
