Not sure what the best forum is to address this problem, but I just got a PS3. I have a Mac Pro wired into the router, and the Powerbook connect wirelessly. I put the PS3 on my network wirelessly, and it works fine until I open the lid on the Powerbook and it connects to the network, at which point it kicks the PS3 off the network. If I sleep the laptop and restart the PS3, I can get back on the network. The router in question is a Netgear WGR614. Also, when my Powerbook is asleep, and I set up a new network connection, I can see mine and other nearby networks broadcast. When the Powerbook is on, I can't see anything broadcast. Any help is appreciated.
