There are many possibilities. Some suggestions on "what to do" in these
cases...
- check in the archives if there are known problems with your network
card model
- type "netstat -i" and see how many errors/collisions it reports
- if your box is connected to a switch or an "intelligent" hub, look at the
switch statistics (errors/collisions on the other end of the link)
- if there are many errors, try another cable
- if there are many collisions, set the link to full duplex (if supported
by both the card and the switch/hub)
- at last, try another network card
