Good morning. I have four ESP8266 boards and 1 ESP32 (2 WEMOS, 2 ADAFRUIT HUZZAH, 1 generic ESP32) that will no longer connect to my internet service provider router. My internet service went down on July 2. The service provider could not solve the issue over the phone and needed to send a technician. The technician came on July 5, removed splitters, and replaced the router. After the router was replaced my ESP8266 and ESP32 board will no longer connect to the router. The 2G and 5G names and passwords are the same. I also have 3 PARTICLE photons and 1 argon and many raspberry pis that were not affected. After the router was replaced all the PARTICLE boards and the raspberry pis connected and resumed sending data.
The ESP8266, and ESP32 board can see the network names on a WIFI scan, will not connect. I don't know how to resolve this problem.
I have a WEMOS D1 brand new that I had not used. I used an example sketch for basic server, the new WEMOS D1 would not connect to my network.
The issue is after my service provider replaced the router my ESP8266 boards and 1 ESP32 board will no longer connect to my WIFI network. Particle boards and Raspberry Pis were not affected, they connect to my WIFI network. I don't know how to resolve the issue of my ESP8266 and ESP32 boards not connecting to my WIFI network. The boards can see the network using example sketch of scan WIFI networks.
Thank you
Perry
