Full duplex NIC running terribly slow

pdeman2 · 11-11-2006, 11:35 AM

One of the NICs on my server (e100) suddenly started running extremely slow quite a while ago. Since then I have been spending time trying to solve this issue with no luck. At first I figured it was a IPv6 issue, but disabling IPv6 makes no difference. Then I thought it might be the cable, but the cable works fine with other NICs. Finally I thought maybe it was a duplex mismatch, but both sides of the connection are running at 100 Mb/s.

I was hoping that this was a software issue, but I tried a number of LiveCDs on this server, and still the connection is far slower than it should be.

Any advice?

I recently had a similar issue, and it turned out to be my switch.

I'm pretty sure it's not the switch for me. I have also tried connecting the server to other switches and even direct connections and it's still slow.

Clean the NIC contacts. If that does not work, assign its own IRQ. If the NIC still does not work as it should, replace it with an Intel or 3com NIC.

Thanks for the help. The NIC was already on its own IRQ and cleaning the contacts didn't help, so I replaced it with an Intel Gigabit card for now.

Are there any other possible reasons this card is doing this?
