Wifi roaming even client is not moving

Recently some user at a area in my office complain me their phones disconnect and reconnect many times. They just only stay in a room. We have APs both front and back of that room. And i found that client is roaming between 2 AP (1 front and 1 back the room). It happen every 1 - 2 minutes.

From coreswitch i ping client IP with 5000 packets, and client roaming 4 times:

I am using WLC 5520, Software 8.7.106.0 and AP AIR-AP1815M-B-K9

 

Can you give me some advice, your best practices in roaming optimization

Tks

I would strongly recommend avoiding this particular firmware version.

Is this happening to only one phone/user?

Is there any reason why you need 8.7.X.X?
Otherwise, 8.5 MR5 or MR6 are good and so is the latest 8.8.X.X and 8.10.X.X.
Avoid 8.6.X.X, 8.7.X.X and 8.9.X.X.
