Configuring "Wireless" always shows "Additional 5GHz Radio" turned on...or its SSID entry available.
When I tap the "Wireless" entry in the Android app (for the Alian), the "Additional 5GHz Radio" option is usually toggled on (even though I've never turned it on). Even when it appears off (eg when I turn it off and save), the SSID name field is available until I turn it on and off again.
@david-nanian does your 5ghz network actually come on? I tried to enable it but no clients see it.
