I have a Wireless network in my home using an Airport Base Station Extreme. The odd problem I have is for months my computer, a MBP, would stay logged onto it. I could have my computer in sleep mode and come to it in the morning and it would turn on and be logged on. Now whenever my computer seems to go into sleep mode it either loses the wi-fi or it won't log onto it when it comes out of sleep mode. This never happened. I had some problems with my Airport Base Station Extreme after doing a firmware update so had to set up my home network again. I thought this was part of it but even removed the network from my MBP and set it up again and the same problem. I have another MBP in the house that's doing the same. Any idea how I can solve this?
