wifi stops working 15 minutes after the start of the program (GIT8266O-418) #848

Problem Description

I am using Esp8266 in WIFI_MODE_APSTA mode. My device successfully connects to the selected network and creates an access point. After 15-20 minutes, I see that the module turns off Wi-Fi (the access point I created is lost, and esp8266 disconnects from the selected Wi-Fi station). In the logs, I see the following message:

D (1774806) tcpip_adapter: if0 dhcpc cb
D (1774809) tcpip_adapter: if0 start ip lost tmr: enter
D (1774813) tcpip_adapter: if0 start ip lost tmr: interval=120
D (1774818) tcpip_adapter: if0 start ip lost tmr: enter

0x40225694: event_handler at /home/pavel/git/viki-wifi/application/main/wifi.c:229

After that, the message in an endless loop displays the following text:

You can restore normal system behavior only by rebooting the power board

Expected Behavior

I want esp8266 to work stably in WIFI_MODE_APSTA mode

Actual Behavior

Turn off the wi-fi module 15-20 minutes after the start of work

Steps to repropduce

1) Turn on the wifi module in WIFI_MODE_APSTA mode 2) Connect wi-fi to the selected network 3) Wait 15-20 minutes

Confirm I am having similar issues. Length of time though is variable.

My code starts in STA mode and connects to the router fine. If the connection is lost (or I use my configuration button), it will start in APSTA mode. Normally I'll be able to see the soft AP.

But when this issue kicks up, I can't see the softAP nor will it connect to the router. Even though the router is fine.

I am also experiencing this issue. I have been debugging for weeks. In my case it uses STA mode only and the time to failure is random. It has taken 1 hour to 48 hours to fail and is variable every time. When I get the 201 (no ap found) error, I have tried multiple variations of stopping wifi, deinit wifi, re-configuring wifi, re-init wifi, and restarting wifi. It never resolves the issue and the AP is never found again. I am convinced that the WiFi component is not scanning at all and reporting AP not found. As soon as the ESP8266 is power cycled, it reconnects to the AP.
