My modem is a NetGear. It is trash. It has to be power-cycled (Unplugged for 3 minutes) at least every 2 days or you start to loose your connection. Its really a shitty one, my friend got one and he said he never loses his connection, its a phone modem. He also lives a block away, so yes, it IS the modem that makes the difference, so stay away from NetGear. My modem isn't actually plugged into my G4 though, its plugged into my old Quadra, which routes the internet to my other Macs.
