it's integrated into the motherboard, it will cost a mint.  if you have USB2, buy a usb to ethernet adapter.  if not, buy an ethernet pc-card.

I baught a PCMCIA ethernet card now...but i was just wondering how much it would cost to to repair it since it was integrated.  ANother thing, why can i not access one of my computers if they are both wireless? if i connect one of them to ethernet it works, but it just won't work with wireless. I have WEPactivated, but since my other computers can access each other wirelessly, itcan't be WEP. Its one computer ( The inspiron 1000 used as a "server") Any ideas?

not really sure ...  perhaps start a new thread and see if others can help?
