Hi,

I had 3 deco m4R model in my house and they are working fine together.

For upstairs i set another m4 but it is not very well connected due to thickness and height of the ceiling. Than I bought a deco x20 to make it main deco at the 1st floor. However, it doesn't work with other m4 decos and connection is going and coming almost contineously.

My questions are:

1- x20 and m4R are compatible? How can ı use them together (x20 as main and the others as sattelite)?

2- Can I use two m4 decos side by side to strength signal for second floor?

3- Is using decos as Access Point instead of Router helping to extend signal range and quality?

Best regards.
