MAX BR1 MK2 (Not showing up when searching for WiFi)

Why doesn’t my MAX BR1 MK2 show up when I search for a WiFi Connection. It shows up on IC2 but when I look for it to connect it doesn’t show up until I unplug it and plug it back in

This issue is happening to me as well. If I reboot the router they show up but after being up for a few days they stop broadcasting. What can I do about this? The unit is in our motorhome.
