Hi all sifus.

Currently I am using 2 units of Deco E4 in a 2000sqft double storey house.
One node connected to the router at living hall and another node placed in the master bedroom located right above the living hall.
But I do experience intermittent disconnection and sometime wifi speed drop. So it's quite annoying.
I tried to place the 2nd node at different place including nearby the staircase in upper floor but it more or less the same. So I am not sure is it because the coverage of E4 is too low, so it is not suitable for my house layout. Since my staircase got a solid wall not those open concept staircase.

So here is my question:
1) Can I pair up Deco E4 with either Deco M4, M5, X20, X50?
2) If yes. Theoretically speaking, since M4, M5, X20, X50 got wider coverage, if I use it as the main node, would it help to improve the connection, so the 2nd node can get a much more better connection from the main node?
3) If no. Then would you recommend the pairing of AX73 + Onemesh extender or 2 units of X50 (Which I set it as router mode). Since both option more or less cost around the same.

Hi sifus

I'm currently using Maxis 100 mbps package which comes with the Maxis Wifi 6 router.

I have the Deco M5. Was wondering if I can use the M5 as a router instead of the one supplied by Maxis?

You can't. The Deco will automatically send AX protocol to any AX devices
That's the limitation of TP-Link mesh system
