Hi , 
Im using for a long time the deco m5 few units .
The main is acting as router to fiber to eth cable transformer .
The wifi is very slow at home .
I guess that the m5 as main and as gigabit router is a tough job for him .

I had im mind a idea to replace the main to a strong archer that can handle both wan and lan .

So wiil the Archer shown on my main deco app or its a separate one ?

As the Archer will be main il replace all decos to be Access point only and then loss some futures .

Please advise
