Community boards for the LG phone speak of this same problem with multiple AP vendors, but most of which speak of the problem when the SSID is hidden, I do not hide it. No solution is known for the visible SSID side of the problem.
Does anyone have suggestions for further troubleshooting on the MT side of things? My only known course of action at this point is to persuade the device's owner to root the phone so I can look at the Android wifi debug logs.
Below is my (mostly) default testing configuration:
