Since lately we have moved to fiber gigabit internet and 2.5gbit lan infrastructure (BE500 router and 2.5gbit TP-link switches over 5e infrastructure house cabling), I am considering to upgrade our existing mesh power line devolo network with 2xBE550 as satellite and easymesh used explicitly for wifi calling as in our house we have poor to none existing celular reception.

And here starts my confusion.

When i initially set up the devolo powerline mesh network after much discussion with both tplink and devolo support (our router at the time was a tplink C9) the consensus was that in order for the mesh to work correctly and not drop the calls while roaming in the house, all mesh nodes should have the exact same wifi settings (ssid, band, channel, channel width) no matter the backhaulth (wireless, lan on powerline) and use 802.11k/v/r. So implemented the mesh on the AC band with fixed channel and width, enabled fast roaming and since then wifi calling is working flawlessly (for 10 years now).

Now, searching all tplink forums i found out that router easymesh does not give you the ability to fix the satellite wifi settings and many complain that fixed channel and width settings dont sync from main to satellite nodes. I dont now how far mesh wifi has evolved but if i change the channel in one of my existing nodes despite that the nodeis still reported as part of the mesh, wifi calling starts dropping the calls when roaming to or from this node. Further more router easymesh mesh doesnt seem to support 802.11r.

So i would like to know if the above is the normal mesh implementation nowdays thus implementing a 3 BE550 esymesh network would not cause any trouble with wifi calling by droping calls while walking in the house.

Furthermore looking at the Deco systems i see that although they support 802.11r, wifi settings are only set on auto with many users complaining that the nodes end up with different channels as reported by their devices and also many are facing wifi calling dropouts. Is this still the case or has something changed with firmware updates as stated as expected in some forum threads.

Finally, since wifi calling is a must for us, as we need good mobile communication for our work (both me and my wife work from home moving around rooms during calls) do you have any suggestion for robust performance especially for wifi calling over gigabit fiber and 2.5gbit lan, preferably supporting 3 band wifi 7 (witch router easymesh or which deco system). The backhaul will be wired through wall lan outlets.

Thank you very much in advance
