I have TP-Link Deco M4 Wifi Mesh 3 pack mesh system connected to the RUTX11. RUTX11 has one sim. The main mesh device has wire connection to RUTX11. Mesh uses RUTX11 dhcp service. TP-Link Deco M4 Wifi Mesh has latest firmware etc patches.
I did the firmware upgrade from RUTX_R_00.07.02.7 to the latest RUTX_R_00.07.03. I did not change anything in any of the mesh devices.
After the RUTX11 firmware upgrade I noticed following strange behaviour:
Initial situation: Mesh devices and RUTX11 are up and running, LAN is OK and there is internet connection (ping 220.127.116.11 OK)
When I reboot the RUTX11 using whatever way (unplug/plug the power cable, web UI/reboot, ssh/reboot) it fails to connect to internet. LAN connections are OK (ping OK between computers in LAN) but RUTX11 fails to connect to internet (I waited max 30 minutes).
Initial situation: All mesh devices are up and running, LAN is OK. RUTX11 is powered off, there is no internet connection.
When I switch on the RUTX11 it fails to connect to internet. LAN connections remain OK.
Initial situation: Both the main mesh device and RUTX11 are powered off and they are powered on at the same time.
LAN connections become first up and running and finally also the internet connection.
Initial situation: Both the main mesh device and RUTX11 are powered off and RUTX11 is powered on first and main mesh device powered on after that.
All connections are finally up and running.
In cases 1...4 I tested only following LAN connections: wired RUTX11 LAN connections, wired RUTX11 LAN connection to main mesh device and several wireless LAN connection of devices connected to mesh network. I did not check RUTX11 wireless LAN connections.
Initial situation: There is no mesh device connected to RUTX11. RUTX11 is either powered off or rebooted.
After booting internet connection and RUTX11 LAN connections are up and running.
I tried several RUTX11 configuration settings to fix the "No internet connection" end state but without success.
I remembered that I did not have this issue with the earlier firmware RUTX_R_00.07.02.7 so as a last resort I downgraded the firmware from RUTX_R_00.07.03 back to RUTX_R_00.07.02.7 and restored the latest backup I had with this RUTX_R_00.07.02.7. Then I repeated all different booting scenarios 1...4 several times and the end result is that the firmware RUTX_R_00.07.02.7 works OK every time in every case: The end result was always that both the LAN connections and internet connection are restored succesfully after booting/power on.
Problem with RUTX_R_00.07.03 is critical because I cannot use auto reboot or any other remote operation that might reboot the RUTX11.
Is it possible that there is a bug in RUTX_R_00.07.03 or should I somehow change the RUTX11 settings after the firmware upgrade?
Thank you for your support and co-operation.
