New 5268AC Moden Intalled: Cannot get imac to join wi-fi network
A new 5268AC gateway was installed in my residence today. All my devices connected with no problem to the new network except for my imac. My imac will not accept the P/W and let me join the network. I tried several obvious things like reboots and clearing out old wi-fi networks in the machine but have hit a dead end. The diagnostic tool was of no help. This is a newer imac running OS X El Capitan.
