Zyxel WX3100-T0

I was using the Zyxel WX3100-T0 product as a repeater and today it disconnected, now its name is not even visible in the wifi list, I reset it and restarted it, its name appeared in the wifi list for a short time, even though I entered the password correctly, it gave a warning that this network cannot be connected, then it disappeared from the wifi list again, I tried with an Ethernet cable and it still did not connect.
