You can manually adjust the UAP radios to reject clients, but things like the LR are really only useful in an outdoor setting, or environments that have sparse clients.
https://community.ubnt.com/t5/UniFi-Configuration-Examples/UniFi-Set-minimum-RSSI-for-clients/ta-p/522637 It’s really an ugly hack and I wish they would allow it to be set under the site or AP. For my home environment, my iPhone thinks it can see the AP up to 1/4 of a mile away with a normal UAP-PRO, which is not really the case as the client doesn’t notice the signal fade as quickly as one would expect. - Jared > On Jan 29, 2015, at 2:57 PM, Mike Hammett <na...@ics-il.net> wrote: > > They should have never made the LR models.
