It is also transmitting packets to the modem, TX count = 8 BUT RX count = 0
so your modem is NOT talking to the eth0 interface, rest of the answer
below.

Please tell us, is the ethernet card a different card to the one you use in
Windows.???? THIS IS IMPORTANT.

Like i said above, its a ONE way link at this minute.

No it's not saying anything, your modem is NOT talking to the ethnet card,
the RX count =0.
Your modem quite possably needs to be reset by your provider and
reconfigured with the MAC address of the 3com card in the linux machine.
Most modems have ONE mac address programed into them, which means if one
changes the ethernet card the MAC address will no longer be valid so the
MODEM will NOT talk to the computer.
You have 2 chooises as i see it, one ask your ISP to change the MAC address.
or place the ethernet card from the windows machine to the linux machine.

dhcpd will (or should) do this when it contacts the dhcp server from your
ISP. Routes will also be added automaticly as well.
All of the above presumes your ISP provides a dynamic IP#, IF you have been
given a "static IP#" then you must use ifconfig to configure eth0 to talk
to the modem and add routes yourself as well as edit /etc/resolv.conf to
reflect the nameserver addressess.

This has little bearing on the presant problem.

30Kbytes/sec is a so called 256k link 60Kbytes/sec = 500K link, 1Mb/sec is
then 120Kb/sec (I hope i have that correct) .
Just what speed should the link be.?? if you dont know ask your provider.
