Wi-Fi on 3 floors, is it better to set up the remote control as a mesh repeater or as an access point?

I have a 7590 as main, a 7490 as mesh, and 2 repeaters, all connected via LAN.

That works, and the 7490 can also take over telephone data from the 7590, but unfortunately not as a DECT repeater.

AC only makes sense if there are also AC-capable devices in the network.

It might be possible with AVM powerline devices, they are also very good in that regard.

Powerline is the absolute last resort when nothing else works.

It is

Powerline is the absolute last resort when nothing else works anymore.

It was about the connection between each other, which then runs via Powerlan and not via Mesh. If there is no LAN wiring

I now have the 2400 repeater still in use in the basement and now the Wi-Fi at FT works great. Really unbelievable that it has already deteriorated so much along the route without walls.
