This may be totally unrelated, but I had a somewhat similar problem with a non-Tasmota ESP8285 device. I found a number of discussions on the web about problems with the ESP device refusing a DHCP offer from the Asus router, which seems to be what is happening in your syslog file. The fix was to add a command to the ESP code to force 802.11g mode [WiFi.setPhyMode(WIFI_PHY_MODE_11G);] Look at https://github.com/esp8266/Arduino/issues/8412 for more details.This morning, after more than four days without any errors, the rude awakening: all Tasmota sockets that were connected to the main router (2.4 GHz) are disconnected and cannot reconnect. In the log I can see that they are trying to reconnect, probably not getting an IP address and therefore giving up the connection.
If I turn the WiFi off and on, all tasmotas can connect again.
I will go back to set up stable 388.6_2 and see if this will happen after 4 days or more too.... BIG SIGH
