Forgive me but I am new to this, but I recently bought an Airport Extreme router 2 months ago and have been having troubles with it timing out after about an hour of use. I have 3 computer connected to it wireless, XBox 360 and a blu ray player wired to it. I can only play for 30 minutes or so before it crashes and the internet goes out. Airport Extreme still shows green light, but the internet does not work until I reset router. The same problem will happen if I use one of my laptops and my iMac (which I bought in January). Any help would be greatly appreciated. Not sure if I am missing a setting or a check mark on a box.
