ESP wifi device lost when network not availble

[PaddyB]

Without touching anything, no issues on my pi 3 model B with OP 1.0.0, internal wifi, ESP connected for successive days, when looking in the ESP logs, never a connection faillure.

My ESP8266 unit = AI-Thinker ESP-01 with 1MB memory with following binary: ESP_Easy_mega-20180403_normal_ESP8266_1024
If needed, I could report current uptime with 0 connection faillures.

But what do you disable and for what reason for this issue to occur?

The Pi shares web access from a mobile phone access point, if the phone goes out of range so no access point to share then the ESP stops talking to the OP access point and needs a reboot to get it talking again. Not really a problem for me as I just went back to using a separate USB/Wifi dongle which works fine but seems like a bug.
