All of a sudden my MacBook Pro (early 08) and my Airport Express (n) are having massive problems keeping connected. Over the last couple of weeks I've had a lot of: MBP not finding my APE, even though it's in the drop down list. When I click it it says I need a password (which it has pre-input in the password box) and, when I click OK, it tries to connect but fails saying "Connection Timeout". It connects but then, 15 secs later, disconnects, then reconnects, then disconnects etc. and this goes on with the wifi symbol in the toolbar switching between black and grey until I restart the MBP. If it does all work, it will often just stop. The internet will hang and when I click to reload, Safari says I'm not connected - even though the wifi is connected. Often, no amount of restarting the MBP or APE will put it right (I've managed to get on right now by completely reconfiguring the APE). Does anyone else have these issues? Anyone know what the problems are? I thought Apple stuff 'just worked'?!
