Does you NIC support 100Mbs? What Manu? What Model? Does your hub/switch/router talk at 100Mbs? 10Mbs? wtf?!

Deatils are needed.

Red Hat Linux release 7.1 (Seawolf)
Kernel 2.4.9-21 on an i686

3c59x: Donald Becker and others.
00:10.0: 3Com PCI 3c905B Cyclone 100baseTx at 0x1080. Vers LK1.1.16

How can I see the current speed. I assume it is 10MB.

You are right

1)in RH 7.x, I just used mii-tool
#mii-tool -F 100baseTx-FD

2)in RH 6.x, have to change /etc/conf.modules
adding:
options 3c59x media_select 100BASE_TX
options 3c59x full_duplex=1

see here:

or
options 3c59x options=4 full_duplex=1
