My call to 3rd level support implied that the network name that you’re trying to connect to cannot have any special characters in it, everything must be alphanumeric. Not sure about passwords. Will try this tomorrow.
If it works, then you’ll probably have to reenroll anything else you have connected to that network. Huge - HUGE - PITA, at least for me. Amusingly, the Ring doorbell has no issues with any network with a special character (well, at least the special characters I have…).
