Clients reconnecting many times to the s(h)ame AP (on several APs)

[ErnestoA]

Hi all!

Just a quick question, I will add more info tomorrow.

My event log is full of some devices reconnecting 100-200 times per hour to the same AP without any more info:

Is a low client density, several floors, 2-3 APs per floor (17x AP121). APs in low power mode (7-10 db), channels were in Auto mode, now in manual non-overlapping. APs don't answer until client ask few times and only if signal is enough good. very slow data rates are disabled.

What else info about the environment do you need? All config seems 'normal' and ok.

Problem appears even when client is still, and it happens on several APs, same config.

Any known bug?

Well at the end I added some info...

Not sure if problem is related to Roaming between APs (client-APs fight?)?

Any way to know 'exactly' the reason why client is moving/disconnects/change connection?
