After power outages here, and activating my back-up 4G LTE hotspot for WAN over Wi-Fi (WoW?)
WAN Failover would not complete a previously working test on the External interface (ISP). I didn't dig into it too far, other than swapping a http test for ping test... because a reboot fixed it.
but that broke the previously working Wi-Fi link test. The Interface actually went missing on a u25xw appliance.
