I just got my new AR750s and I think there is a bug in the UI. When I change the wifi password to a long one (say 40+ characters), I am unable to connect. This applies to both the 2.4 and the 5GHz bands.
Perhaps there is a maximum password length? What is it?
The wireless password is 64 characters limited. It should work. Could you please comfirm you connect to it with the right password which is so long. Does it includes any special characters? What’s your password?
