Clients still getting kicked from AP.

[jason_sparrow]

I think the various questions i am asking are getting lost in other threads so....

Could someone tell me why i'm seeing this...?

"wmi_peer_sta_kickout_event_handler:838 Kicking off STA *************** AID 1"

I am also seeing the above, but with AID 2 at the end.

Thanks.

Do you still have ChannelFly or SmartRoam enabled? I've definitely noticed that my iPhone, if kicked off a network via SmartRoam, will not bother using the wifi network again for several minutes unless I manually reconnect it.

If you are having random client disconnect problems, I would highly recommend going to a static channel assignment and disabling smart_roam if you had turned it on as a part of your roaming optimization attempts.

I've got a household of 15-20 Apple devices and have not seen any connectivity / disconnection problems with them.

Thanks for confirming that this (smartroam problem) is "normal".

In my case it seems like the iPhone gets smartroamed back and forth between APs several times, and then gives up on WiFi "permanently". (or until the device gets locked/unlocked, etc.)

There are courtyard areas between buildings where this often happens.

 I've had this user complaint many times, and mentioned it to tech support many times without hearing any explanation/confirmation.

smartroam solves serious roaming problems for me, but if I use it, I shouldn't expect my iPhone devices to work...

Yeah, I don't know what's "normal", but it definitely feels like the iOS devices take SmartRoam disassociations to mean "please don't connect to me for a while"... I've found bss-minrate is a more effective mechanism to reduce coverage radius for iOS devices.

I've also found that even for WPA2-PSK networks, enabling 802.11r/k (such as in a controller environment or possibly in Unleashed) causes iOS devices to roam more frequently. Ever since I turned that on, I haven't had a need to further change roaming related settings.

@ Bill

If you have smart roam enable and there is a lot of shifting going on, then I would recommend that you need to adjust your smart roam value

[bill_burns_6069]

There has been much tweaking of smartroam values.
At a certain point (with over 100 APs) it becomes overwhelming.
Plus, settings that work fine indoors may not work well for iPhone users that are standing just outside or between buildings. (like when they step outside for a smoke break)
