Hi,

Thanks for the reply. There's nothing on my home network here. It is
just a direct connection from my PC to my cable modem and there's
nothing in between. I've googled a bit and it seems others also
encounter this problem. I've read a few posts on the Ubuntu bugzilla
where people change the MTU from 1500 to 1492 and this fixes the
problem. However, even with this, some report that the problem is
still there. I did the same and it didn't change anything for me. So I
disabled my onboard NIC and added a 3Com one which has been working
perfectly so far and I think I'll just keep using it instead of the
Marvell one.
