I have 3 Deco X20s and 1 Deco M5 connected via Ethernet backhaul via a switch from the living room. The main unit Deco X20 in the living room is acting as a router to the rest of the 3 units in MESH Mode.
I have 1 unit of Deco X20 in my study room that has very bad wifi connection, less than 10 Mbps on speed test, connected to WIFI 5 Ghz.
When I reboot the unit in the study room, it will not connect via Ethernet backhaul, but connected via WIFI to my Master Bedroom, which is 5 meters away in my Apartment.
In addition, I have a 1 GB speed internet plan, but the max WIFI speed test that I got is close to 250 Mbps, directly in front of the router, is that reasonable?
Does anyone face slow WIFI issue with Deco X20? Seems like this new product is not very stable in terms of WIFI.
Hope that TP-Link support team cn help.
