I have a problem, my DSL router shows the "wireless" light and sometimes it doesn't. I connect my desktop to the router via usb but a laptop downstairs connects to it wirelessly. My problem is that i recently purchased a new desktop for another room in my house, and it can't connect wirelessly like the laptoop can. The new desktop is running xp and when I scan for wireless networks, it doesn't show any, but the laptop shows 6 (neighbors, offices, etc.) Any advice on how I can get my DSL router to permanently send out a signal, or how to get my desktop to successfuly scan for networks?
