Deco M4 ethernet backhaul issue
I know, my post is one of the many others in this topic, and I swear I read many other posts, but the ethernet backhaul still does not work for me.
The setup is simple:
One Huawer B565 4G modem/router - connected to the "master" Deco M4, then an ethernet cable goes from this "master" deco to the other one.
Still there is not ehternet backhaul, only wifi.
I have one suspicious thing here: the ethernet connection is: cable goes into the wall connector and there is a connector in the other room, and a cable into the slave Deco.
I have tested the wall cable with a cable tester, all leds working fine, so I guess all wires are ok.
What can be the problem? however there are another connectors on other rooms (unused), and all the rooms cables are soldered together like a star - wire by wire - in a central place. But I just use it as an extension, and as i said ethernet tester shows its fine.
