Didn't notice this at first, but most of the time my 2013 15" rMBP now wakes from sleep, it can't see any wifi networks. If I cycle the wifi (turn off and back on), it picks up my LAN fine. Speeds are good and the connection is reliable once it's made. Anybody else noticing something like this? I'm certain it's the MBP, not my network since all the neighbor's SSID's disappear as well as mine. Guess I'll call Apple tomorrow and see what they have to say.
