I recently replaced a FE 3Com card in my Linux server (hostname is

matter what I do. I tried forcing it using 'ethtool -s', and setting
autoneg off and on. Rebooting didn't help. Using a different port on
my GigE switch/hub didn't help.
BTW - I also put a duplicate Netgear GigE card into another Linux server
(hostname is numenor; additional NIC, not a replacement -- if it
matters). On numenor, that NIC is at 1000FD.
I have not yet tried swapping the port and ethernet cable between
imladris and numenor...
That would be a great first check - eliminate everything you can.
Are you using a cable with all 4 pairs correctly wired {for 1Gb},
whereas only two pair {for 100Mb} ?
Are you using a switch ? If not the crossover has to crossover 4-pairs
correctly !
Is it a reasonable distance ? proper cat 6 cable ?
