Guys and gals, My Macbook Pro w/retina takes forever, 2-3 minutes to find wifi signals and then connect to my home and office networks. This happens every time it "wakes up" from sleeping of when booting up fresh. It used to be near instantly and all of a sudden started doing this. The only way to get it to connect faster is to turn WIFI off, wait a few seconds then turn it on. A real pain. Any ideas?
