@bignate:
If it is correctly installed, you should have an AmiTCP: assign. You check if you do by typing in 'AmiTCP:' in a shell and pressing enter and see if it works. It is started with a script called 'startnet' in the global path and stopped with a script called 'stopnet'. Though you would most probably have to configure it for your network.
A tip on the Amiga is to click around on your harddrive-partitions and see what you find for goodies in the drawers there.
Btw, it would be quite possible that your network card is a Commodore A2065. Oh well, showconfig will tell you if it is as it is one of the few cards it have a name for in its small database. For cards that are not present not in the database, you will only get the manufacturer and product number. You can search what expansion that matches what numbers on
this page.
