I am not computer literate so bear with me. My daughter recently got a laptop - we have a Linksys Wireless G broadband router. All of a sudden, she can't get online and the Windows XP balloon comes up at the bottom of her screen and says LAN - network cable unplugged. This was all set up by a "professional" so I know it was done correctly and it has worked fine for about a month. My daughter says she hasn't bothered any of the cables on our home computer. I am at a loss and on the brink of losing it - 14 year old girl, no internet connect??!! Please help.
