Description

Hello everyone,

I do face a very weird situation. I have 2 ESP8266 12e.

• One that I worked on early 2018, on which I have Wifimanager library (don't remember the version since I upgrade this version since then).
  = > this board is connected to a wifi router

• Two other boards on which I've bee working for 2 months and on which there are Wifimanager library also (version 0.14.0)
  = > These 2 boards are also connected to the SAME WIFI ROUTER.

The problem is that the last 2 boards launch the config portal randomly (for an unknown reason) : the Wifi routeur is always on WHEREAS the former board (on which I worked on early 2018) does NOT launch the config portal randomly.

The expected behaviour would be the 1st behaviour (that on the former board).

Can someone please help ? I cannot figure it out.

Here the code of the older board

Yes I did every time I upload a sketch I tick "erase all flash" on the ide config. Then I enter the portalconfig and select the wifi router.

No cause this behaviour started happening despite the board was New. 
Can you confirm one thing ? Autoconnect is about connecting to a wifi routeur, Nothing to do with either or not there is internet provided by the wifi routeur, is that correct ? 
Cause sometimes even if the routeur is on, there is internet connection problem.

yeah sounds like something with the router I think there is some kind of problem disconnecting and reconnecting perhaps, the only thing I can think of is increase connecttimeout, or add your own loop ir delay and see if it fixes by letting the router reset the lost connections.

Have you checked to make sure your esp is not wdt reseting, causing these resets

Have you tried disabling sleep
WiFi.setSleepMode(WIFI_NONE_SLEEP); // disable wifi sleep

Seems like the router sometimes has some pblms assigning ip addresses. But the weird part is why the old board is not portalconfig showing whereas the newer ones are ?
