I finally got it to work!!!

I forgot who mentioned it to me, if it was on this board, on the Networking board at apple (apple.com) or another programming board I belong to (can you tell I was really desparate?).

Someone suggested I completely power off my cable modem as it probably only recognizes the first MAC address it is connected to.

So as soon as I got home from school and unplugged my cable modem. While it was unplugged, I plugged in the cable from the modem to the WAN port on the ABS and then added another cable from the Ethernet port from the ABS to my PC.

After that, I powered up my cable modem and it connected just fine. Then came the testing. I tested the PC first. Started up Opera and it connected just fine!

Then I went upstairs and powered up the PM. and it instantly recognized the connection and went from there.

Thanks to all. I have another question, but since it's not "Networking", I'll post on the appropriate board.
