I have an ESP8266-12E, I used it previously and it worked fine (approx 2 years ago)
I can't seem to get it to detect WiFi networks or appear as an Access Point
I can upload the blink sketch and the onboard LED will work correctly and the serial monitor will show output from the ESP8266, but there appears to be no WiFi functionality
I have tried using previous versions of the ESP core board definition via the Arduino board manager
I have tried using an external power supply (wall plug) rather than the powering from a USB port
I have tried erasing the flash using esptool.py
I have checked that the WiFi router I am trying to connect to is operating at 2.4Ghz (also there are other WiFi networks around and I set up a second router to make sure)
I have tried connecting to the Access Point using the SSID (with and without a password) despite it not appearing
I have tried getting it to connect to an Access Point even though none are found
Is there something I am missing or should I order a new module?
Any other suggestions please!
