Hello,

I recently set up a backhaul connection between my deco devices. My deco is set up a access point. I have 3 deco devices, 2 X60 and 1 E4. The main device is one of the X60s.

I have a 1000/300mbps connection from my ISP.

I installed RJ45 wall ports (the ports are cat6 and the cables between these ports are cat 6a). Wall ports have this configuration : cat6{port} - cat6a{cable} - cat6{port}

So here is my home network configuration :

Archer D2 -> cat7{Switch TL-SG108E}, cat7{Deco X60_main}

Switch TL-SG108E -> cat7{wall port1}, cat6{wall port2}, Nintendo switch, TV etc.

cat7{wall port1 -other side-} -> cat6a{Deco X60_2}

cat6{wall port2 -other side-} -> cat6a{Deco E4}

So the deco E4 is on 100mbps, which is not surprising since the ethernet port on the E4 is limited to 100mbps. However, the deco X60_2 is also limited (based on the LED from the switch and the speed test when connected to this mesh device) to 100mbps while the X60 ethernet port is up to 1Gbps.

Do you guys have an idea why ?

Thanks for your answers.
