Whenever I wake my MBA from sleep, it NEVER connects to my saved networks. It worked well for the first month of owning it, but now it's a mess. It's infuriating and takes forever for the wifi to realize it can't connect, ask me what network I want, and then slowly connect. I've reset the PRAM and deleted and resaved the network settings but neither method worked. I considered taking this to the genius bar but I don't see how they can help since this seems to be solely a software issue. Any help would be great and I would be interested to know if anyone else is dealing with this obnoxious issue.
