ESP8266 Community Forum

I use my ESP8266 mainly with ESPEasy or Tasmota software. These ESP are connected to my ASUS RT-AX86U Router. I don't understand why I lose my connections with some of them very regularly. On my 10 pieces, 50% are often lost. I have added rebout scripts mainly on the ESPEasy if it had no connection, but this does not solve my problem. I can't find the cause of these problems. Are there any tools for that.
Many thanks in advance for your help
