Force per-client band and access point
Within client details we should be able to force a particular access point and frequency for the client. I have a wireless doorbell which connects perfectly for 2.4Ghz to my mesh point, but seems to try to prefer 5Ghz yo the same mesh point and then complain about poor signal. If I could just disable 5Ghz for this client it would be perfect.
Additionally, being able to define custom additional SSIDs with certain characteristics (band selection, APs in the group, frequency) could be a further way to solve the problem.
