Disabling the data rates is the preferred method of doing this. A few WLAN vendors (Aerohive and Ubiquiti are the ones I know of for sure) allow you to set a Min RSSI value. If a client’s SNR drops too low for X number of TU’s, then AP will deauth the client to…persuade them to pick a different AP

I will report if it helps with sticky clients or not. This is assuming there is enough RF from surrounding AP's. https://gtacknowledge.extremenetworks.com/articles/Solution/Issues-with-clients-staying-with-an-Access-Point-that-has-bad-signal-Sticky-Clients -- Jeremy L.

This feature was just introduced and we have a lot of "sticky" clients that don't like to roam even though there are more desirable AP's in the area. I have enabled it on a handful of AP's for testing, but would like to hear what others have experienced. Thanks -- Jeremy L.
