OK, here's the situation. I have a WiFi network in my home pumping out ultra high-speed broadband throughout the house. We are an all Macintosh house, until #1 son comes home and fires up his PCs. He has a desktop and two laptops. When his PCs are one, we will, at random, just lose the WiFi signal. We have to unplug the WiFi router and plug it back in and it will go for four, five, six hours until it drops the signal. When I power down my son's PCs, we have no more problems. Would anyone care to give me some idea of what is happening here? Any *easy* solutions?
