Hi I'm having trouble getting my Ethernet port to work on ubuntu 10.10. I'm new to ubuntu. I've looked under System Info and it show my device: Broadcom Corporation BCM4401 100Base-T (rev 01) but when I look in Network connections it doesn't show up. any help?

If you connect a cable, it should show up as eth0.

You can open a terminal and type

ifconfig eth0
It should return something like

eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
Interrupt:16 Memory:ee000000-ee020000

This means the interface is there, but hasn't been configured.
If the interface has been configured by a DHCP server, it should be more similar to

wlan0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx
inet addr:176.16.1.14 Bcast:176.16.255.255 Mask:255.255.0.0
