I suspect the problem is well above the network driver level.  This is
a fundamental TCP/IP stack problem, almost certainly a botch in the TCP
code involving a retransmit timer or some such.

Actually, come to think of it I experience this issue exclusively
with ssh connections (which is the bulk of what I do from home),
which is definitely TCP.

Indeed intel has their own network chips and the 3Com has their own
silicon as well; and the drivers are totally different.
This is not a chip or driver problem.

If the kernel developers would just stop reinventing the wheel, ...
 ...  (oops, I didn't say that).
