I am using Wifimanager for wifi setup in my projects and as usual it presented the captive portal for wifi credentials and works fine.The issue I face is if for some reason there is a Wifi disconnection(powerfail) it usually enters after certain time into captiveportal/access point state where I need to restart the ESP8266 to make it connect to earlier saved WiFi information once the WiFi is back else it will simply remain in access point mode/captive portal state, I wanted a way if possible to continuously try after certain time for saved Wifi connection information

- Mon Jul 29, 2019 2:20 am #83260 I didn't make myself clear. I meant when the timeout occurs the control is passed back to your sketch and you can then have code which automatically checks whether the local wifi has recovered. No manual intervention is required.

So, if wifi fails, then using a timeout, the module can automatically cycle between activating the portal for a period followed by checking if wifi has recovered. This continues until either the wifi has recovered or you choose to use the portal to change the wifi network.
