Hello!
I have a fresh El Capitan install on my iMac at work. The weird thing is that it will disconnect the known Wifi access point every few seconds. Sometimes it will connect again to it, sometimes will drop it and not connect again and somtimes will ask me to enter the password again.
I understand from other forums that this is well known issue with the beta version, but my copy is the official release from the app store and I wonder is there a workaround my situation?
