Try not auto neg. Try manual assignment. also check switch port has not
been set to 100mbs by accident.
Try another cable?
Thanks,

Hi folks,
I have a GigaByte GA-M51GM-S2G motherboard with an MCP51 gigabit NIC, with a
MARVELL PHY. It's plugged using CAT 5-E cable into a gigabit
switch. But it insists on connection at 100Mb/s.
There are other gigabit connections that are workking at 1000Mb
into the switch.
Any ideas on how to fix this? Or is the PHY cactus?
