[SOLVED] No Broadcom BCM57760 eth0 Interface in LiveUSB

I'm trying to install Arch using the "Beginner's Guide."  I've used Arch before, back when there was an actual installer, but now I'm a bit behind.
The strange thing is that when I boot into the liveUSB and try to configure the network, my ETHERNET adapter is not detected.  Lo, wlan0 are both fine, but no ethernet.  How is that even possible?  I have *NEVER* had an issue with ethernet...ever.  I have access to an ethernet connection, but no available wifi networks.  I'd really like to know why there is no eth* interface so I can solve this problem and get on with my install...

Without knowing which ethernet card is in there, it's impossible to help you. Post the output of lspci -nn on that machine.

I solved the problem by first running

$ lspci | grep Ethernet
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57760 Gigabit Ethernet PCIe (rev 01)

The module my card needed was tg3, which (as I had thought) was loaded automatically at startup.  However, for some reason I had to unload and reload the module to get it to work:

# rmmod tg3
# modprobe tg3

Marking thread as solved, thanks for offering to help
