Wifi hangs on early 2015 MacBook Pro? It happens regardless of what network I'm connected to. Every hour or so, the internet connection will just load forever. Nothing else changes as far as I can tell, the wifi menu still says "connected" and "internet reachable" but webpages will not load. Reconnecting to the network / turning wifi off and on will always fix it. Early 2015 13" MacBook Pro Retina.
