Deco m9 plus 3 by cable
Hello
The rest of the devices are distributed between the first and second floors, both of which are connected to a network cable. Is connecting the rest of the devices with a network cable is useful or not. Preferably connected without a cable so that the connection between all devices via wireless only
My question is because I noticed that the speed of the Internet is excellent but the quality of the wireless coverage was not as I expected, as there are some places to call the signal, although it is not far from the whereabouts of the device
