Vince,

Try turning off auto-negotiation on your Ethernet card.  Set it to
100Mbps full duplex or 10 Mbps half duplex.  I had a similar problem
with a realtek card.  I think it was an 8139.  It did not negotiate well
with a dlink router.

ethtool or mii-tool should help determine which works best, then add the
appropriate option to /etc/modprobe.conf.  I could not find a definition
of realtek's supported kernel parameters in /usr/share/doc/...  Maybe
google.
