Slow net speed on Intel DG965OT motherb. with 82566DC NIC

Hi

I’m running Suse 10.2 on my Intel DG950OT motherboard. The network card on this motherboard is Intel 82566DC.

For some reason I can only get 100Mb/s connecting when connecting to 1Gb/s switch, but when connecting straight to another computer I get a 1Gb/s connection. The odd thing is that just some weeks ago I was able to get a 1Gb/s connectiong to this same switch! As far as I know, no settings have been changed on my Suse that might affect this.

I’we tested the switch thorougly and changed the cables, but still I only get 100Mb/s speed.

Anyone know what might be causing this?

Also, if I don’t find a solution to this I’m going to buy a 3rd party NIC, what cards would you recommend?

Here is the output of ehttools, if that’s of any help:

I noticed that the newest drivers are version 8.0.9, but mine are 7.1.9. Might upgrading the drivers fix the problem? I’m not so sure, since I’m able to get a 1Gb/s connection when connecting straight to a computer.
