Hi!
It depends on the desired speeds on your WIFI devices:
By separating the 2 bands 2.4 and 5 Ghz with 2 different SSIDs, this will allow you to capture the WIFI valid on your most distant devices but with a limited speed.
Otherwise, you can get mesh repeaters, if your home is very large.
You can use this application on your mobile, this allows you, depending on the rooms in your home, to know the maximum speed offered on the 2 bands depending on the position of the R3.
Do the test on the 2 bands 😉
