I'll start by describing my set up. I've got a DSL connection connected to a Linksys wireless G router. I have wired lines running to a windows pc and up to my room to my macbook (if I feel I need a wired connection). There is also a window's laptop and a mac mini on the network. Along with a nintendo wii PS3 and two Tivos. All connect nicely to the Mac Address protected wireless network. As soon as I begin using Airport on my laptop however, give it about 10 minutes and the connection drops. Not just for the mb but for the entire house. I'm completely clueless why only when my macbook connects the connection drops. I appreciate any thoughts or input you might be able to send my way. If you have any questions please let me know.
