We run a multi site environment with a 5508 controller at each site and central WCS with 3502 APs.
Having an issue atm where a user is sitting and in proximity to 3 APs (2 in her room, 1 on the floor beneath her, solid cement floor).
Her NIC windows connection is randomly and frequently dropping out, on WCS I can see she assoicates between the 3 APs at these dropout intervals, the problem AP being the one beneath her.
Is there a way I can block her from 2 of the APs somehow or force her to prefer an AP of choice? (have tested with different laptops/users in same location and same issue occurs, APs do not go offline and the network backend is all stable).
There is no configuration to BLOCK a user from a given access point. I would make sure you don't have client load balancing enabled and maybe adjust the client device roaming aggressiveness. Depending on the wireless card, most have some sort of adjustable setting.
If the device does associate to any of the APs, they should still work fine. Is there an issue with maybe one of the APs? What do you mean by problem AP? Is the user complaining or is it because what you are seeing in WCS?
Well since you mentioned dense deployment, then I would think your running into this issue. Even when I deploy 188.8.131.52, I will not enable client load balancing. Even with newer clients, doesn't mean the manufacture will honor status code 17. Disable that feature and let it run for a couple days and see. I would think you would have more issues than with one client.
