Deco X50 VERY weak signal
I got a 2 pack Deco X50 to work as access point to expand my wifi coverage. My House consists of 2 floors. In the 2nd floor, I plugged one unit with the modem and it works good with the full speed reaching 500Mbps, the another unit on the 1st floor which is located directly under the first unit gets VERY weak signal and speed of 1Mbps, which is not supposed to be at all. I tried to move the unit to only a few meters beside the main unit in the same room, and I got medium signal strength, which easily suppose to get strong signal. any solutions to this problem?
