There is a bug in the WiFi password system. The WiFi system will only use the first 58 characters of the password field when authenticating.
I have a WPA2 WiFi network that takes a 61 character password. When I type in the password the Max 3 fails to join the network. However, it will join the another network with a shorter password.
If I paste in the password into the WiFi password field, the text field only accepts the first 58 characters. Typing in the remaining missing characters will cause an authentication failure.
