Posible NTP problems with internet restricted Wemos ESP8266 #812

Closed pvossel closed 7 months ago

In my network I have alot of ESP8266 and ESP32 devices (Tasmota, WLED, Zehnder, etc). I want to restrict internet access for these devices. Only downside is, if they try and communicate with an external NTP server but cant reach it they become "unavailable" for a vew seconds. Something is happing to the WIFI. Not sure if its a reboot of the ESP8266 or reconnect with WIFI. I can mitigate this with most of my ESP8266 devices by using a local NTP server.

Now I am also experiancing alot of "unavailable" Milight lights in Home Assistant. My assumption is that this is the same problem.

Im running Milight Hub on a Wemos D1 mini (1.10.8 d1_mini).

Posible solution, configurable ntp server?

I've updated to the latest firmware 1.11.1 (d1_mini). Same issue here.

Serial connection not showing any usefull logging for troubleshooting.

Hey guys, sorry for the late reply here.

I don't use NTP in this project. It's possible something else is using it behind the scenes, but I kind of doubt it.

I changed the default WiFi mode from N to G in 1.11 -- I suspect this might be the cause. Can you try swapping wifi mode to N?

It was already on N. Changed it to G. Problem solved!
