So does Yosemite wi-fi do the auto-reconnect from sleep properly? Mavericks and earlier versions have had such annoying trouble with their inability to reliably reconnect wi-fi after the Mac wakes from sleep. There have been countless threads here about this issue. It seems to be the worst on my Mac when it sleeps with Safari open. I typically have to turn wi-fi OFF, then turn it back ON again. Sometimes I then have to go a further step and point it right toward my network name. Has this problem been resolved with Yosemite?
