1 Wifi radio Qualcomm Atheros IPQ4019 802.11nac - Device Is Not Active

I'm not sure why, but this radio, listed as Radio2 is not showing as Active. I have removed the wireless network, and added a new one, and associated it to the lan interface, and applied all changes, but still the Radio shows inactive.

I don't see anywhere to try and make it active. This is an Asus Lyra Mes map-AC2200 router. Any help on getting it to activate is much appreciated.
