I have a linksys WRT 54G wirless router. It stopped working and after reading some posts here I removed the mini pci card and installed it in my compaq presario 2140 laptop. XP saw the new devise and loaded the drivers. I know my laptop does not have antenna. I see all kinds of them listed on ebay. I was wondering if anyone has ever added antenna to their laptop? I see on e-bay here they have antenna that would fit behing my screen, for about $9.00 Before I spend the money going any futher I wanted to see if somehad done this same project. Any advise or suggestions?
