Is anyone else going crazy because of the constant disconnection on Yosemite when their Macbook wakes up from sleep? After I open my Macbook lid, the wifi is searching constantly and it takes anywhere from 1-5mins to find connection again. Does anyone have any fixes? I've tried turning off Wifi then turning it back on and I thought this would make it turn on instantly and work but I still have to wait minutes for it to be stable. Thanks!
