Deco M9 - cable connection when weak sign
Hi,
Few months back I bought Deco M9 plus, 3 routers for my house (140square meters).
House has 3 small floors, main router installed at the top, each device has 1 floor to cover. I hoped each device will have a good signal, but its not the case.
The lowest floor has weak signal, but it's the most frequently used room. Is it possible to connect two devices with a RJ45 cables? I have a cable between top & bottom floors so it would be great if I could connect them through cable. I'm trying but cannot see any signal improvement. Does the cable connection have to be configured? Would this work?
Is there any way the signal may be improved?
