I am having a problem staying connected to the internet. It seems to have happened every since I upgraded to Snow Leopard. I can connect fine if I plug in the ethernet cord directly and will stay connected. That is not the case wirelessly though. I can't seem to stay on the internet for more than 10 minutes before it stops working and I have to go through network diagnostics to get it to connect again, where it tells me my ISP is failing every time. It seems to only be my computer as well. Everyone else's computer in my house seems to work fine and consistently on the wi-fi. Anybody have any suggestions for how I can fix this?
