I have a Dell Latitude (thanks for the sympathy), which is wirelessly networked via Netgear card to my DSL router. This router is hardwired to another computer which gives me no trouble. My daughter has a Toshiba laptop with its own internal wireless equipment. If I am on my laptop, and my daughter goes online with hers, mine will either freeze, or reboot. This happens every time without fail. Any ideas why, or how I can prevent this. It doesn't seem to happen with any other wireless laptop if a friend or relative comes over and uses my network.
The computers are not linked for file sharing or printer sharing or any other sharing. We cannot "see" each other at all.
