I have a Dell C610 laptop which has a WIFI card in it. Originally it
had Windows 2000 PRO and Boingo wireless software. I was able to
access internet wireless, all our computers were networked etc. Then
she wanted to add a 2nd operating system (XP) and needless to say it
didn't go well. So now my sister erased everything on the laptop only
has Windows XP now.

The problem is, it keeps saying that the wifi card is not present.
Where is the wireless card? Do we have to open up the laptop and
reinstall the wireless card so it will recognize it?? Help!!
