Hi
i have WLC with 15 Active AP , i have big problem , for example i have 2 AP nearly me , 1st one far me about 2 meter and another one far about 7 meter , the problem is my device connected with 7 meter AP !! and didn't connect with the near one!!
so the service be very bad , and if i have another AP far about 10 meter and i tried to restart the (7meter) access point the device connected with (10 meter) far away !!
the nearly access point that far about 2 meter work normally and more one connected on it !!
so what the solution of this ?
and another query : can i set the signal of AP to swap me to another AP before the signal be poor to stay the service stable ?
and what that ( RSSI Threshold (-60 to -90 dBm) ) mean ? is that relation with signal of AP ?
thanks

Update the wireless NIC drivers of the wireless clients.

Roaming decision is taken by client, so you have little control over that from AP point of view.
Once client associated to a AP in a cell, it will stick to that AP unless, it is roaming criteria triggers. Therefor each device behavior will be different, some vendors do not disclose these details, so it is hard to know exactly what conditions make them move to next AP. Here are some of those details for Apple & Samsung devices.
I would check power level of those AP & ensure they all have similar power levels, also if possible just have your SSID on 5GHz band (instead of dual band- that will prevent from client move between 2.4GHz & 5GHz without roaming to another AP)

Android OS don't have a good way of WiFi roaming. This is why someone came up with an app called WiFi Roaming which works very well with new and old Android devices.
For Apple, make sure the OS are updated. Apple smartphones and iPads didn't really know how to roam until iOS 10.X.X. So if there are old phones running 9.X.X (and older) then there's nothing to do.
Finally, pick an AP in question. And issue the WLC command "sh ap auto-rf 802.11a <AP Name>". Make sure you download the complete output for the 2.4 Ghz & 5.0 Ghz radio.

Ok, so how abut 802.11b radio?
RSSI between the NOC AP and the other 3 is very low.
