AXT1800 can’t connect to specific WiFi anymore

My AXT1800 was connected and working fine (on repeater mode). Suddenly, the connection dropped and the AXT1800 cannot discover the same WiFi network that it was previously connected to.

It can discover and connect to other networks.

It doesn’t work when entering the network SSID manually either.

So, the AXT1800 is working and the network is working. They just cannot be connected again.

Does perhaps the source SSID have it’s band set to Automatic and it’s changed bands to something that the AXT1800 can’t see because of regionalisation?

We would require more information about the network you are connecting to.

Who is owner of it? What frequency and encryption?
