iOS 9.3.2 Wireless Won't Connect
I have a large number of devices in my home that connect to my Watchguard XTM21-W. All my Android phones (4) connect without issue. My MacBook 2011 connects without issue. My 2 Windows notebooks connect without issue. My iPad 2 running 9.3.1 connects without issue. A large number of visitors to my home also have no issues with the wireless.
But my iPad Pro 9.7 and iPad Mini 2 both running 9.3.2 will not connect to the wireless. It says invalid password every blessed time.
I've looked high and low for a solution, but not found one. I did try every suggestion that forums indicated, such as resetting networking on the devices, trying static settings, etc. I have 3 of these Watchguard firewalls, and I tried a 2nd one but its behavior is the same. I've set the firewall/router to different settings and encryptions, and even removed all encryption to try and these iPads running 9.3.2 just won't connect.
Anyone have a new suggestion?
