I recently bought 3xDeco M4 units. I set up all 3 of them as wifi router (default) and the wireless mesh functionality is great, but I can't connect my computer to them via ethernet cable. On my computer  I just see "Unknown network, no internet". In the Deco app on my phone I see that my computer is connected to the network via ethernet too and if I unplug it it disappears. I tried connecting other devices and to different Deco units all with the same problem. IPTV/VLAN is disabled.
