EasyMesh with Ethernet backhaul (2xAX55 + 1xAX58) - Internet connection is lost several times a day
Hi community,
I have some issues with my newly build Easy Mesh WiFi network with ethernet backhaul.
The configuration is working fine, except the fact that the internet is lost several times a day.
Resetting the main router of the Easy Mesh network solves the issue then.
I have also tried several different settings (DHCP server, RX TX flow control, only 2.4Ghz WiFi,...) but none of them solved the issue completely only the time between the issues changed.
I have 2x AX55 v1 router with firmware 1.3.3 Build 20240628 rel.37017(4555) and 1x AX58 v1 router with firmware 1.4.3 Build 20250314 rel.78903.
All routers are connected by ethernet cable in different locations in my house (1x in the basement, 1x on ground floor, 1x in the attic).
The Mesh Master is configured to AP mode and the WAN port is not used for the ethernet connections.
The internet connection is provided by an AVM Fritzbox 7560 which is provided by the ISP 1&1 in Germany and via ethernet connected to the Easy Mesh master which is one of the AX55 routers.
My topology:

It seems like the ethernet connection from AX55 Mesh Master to the Fritzbox is somehow shutting down from time to time.
In the logs of the AX55 Mesh master is mostly nothing visible except for the LED changes.
The internet connection of the Fritzbox is stable. I have checked this via direct ethernet connection to the Fritzbox.
I have seen some similar posts in this forum but found no clear solution.
Looking forward for some help.
Best regards,
Benjamin
