Time between connecting to wifi and starting the webDAV server

[Sineos]

I have the issue that I need to reboot sometimes multiple times for the firmware to successfully start the webDAV server. From the terminal output it is always the same:

1. Initial WIFI connection is shown as failure
2. M53 also says Wifi not connected
3. In my router and the access point the SD-WIFI is shown as successfully connected
4. Sometimes another M53 will show success and the webDAV is started. Sometimes only (multiple) reboots will help

For me it looks like that some timeout fire too soon and are not giving the WIFI connection enough time to "settle"

Hello, unstable wifi connection is generally a signal problem, this module is a weak signal caused by an on-board antenna, you can try some ways to enhance the signal, or enhance your router signal, this problem may be improved.

Thanks for your advice and you are totally right. I know these ESP beasts pretty well, since I have around 8 ESPs as various IOT devices in my home. Further I have 3 enterprise level access point distributed, providing a pretty good WIFI coverage.

The point is:

• I see the device in my access points
• I see the device in my router
• The device does not recognize, that it is actually connected and prints a failure message

I made following changes and since then never had a single failure to connect and start the webDAV server:

I would assume the critical change is increasing the delay from 100 to 1000
