I think its an ethernet cord, but I dont know what that usb cord in the back of her comp is hooked up to. I'll probably be able to sort it out today when I go backover, its just that I was trying to do this at like 10 last night rushing. It'll probably be better with fresh eyes...
It sounds like the drivers need to be installed for your network card.
When you did a fresh install of windows did you install those drivers ?
If not, try browsing the CD and see if you can find the drivers because it will not automatically install them.
You may have to find out what network card (NIC) you have first, try going to
control panel/system/device manager and see if it is listed under network adapters, it may have a yellow exclamation mark next to it.
If the NIC came from SBC with the modem, I think they used a D-LINK.
If this doesn't help just come on back here and one of us will get you going ;)
