WiFi Clients Unstables

[Mario Andres Proano Navas]

Dear

We have problems in my wifi, I have WLC 2504 and 5 APs, however clients are experimenting flapping in the conexion, I verified with a client, and this one is jumping from one AP to other one, also I have some debug, you can see that in the attachment.

Thanks for your help.

Do you have enabled client load balancing ?

Menu: WLAN --> Choose your WLAN --> Advanced --> Client load balancing

If it is enabled then try to disable it

Dear Milos

Client load balancing and band select are disabled.

[Milos Megis]

Then I don´t know what can cause this,

but if you have AP with cleanAir chip, you can switch it into SE expert mode and perform some spectrum analyzes, if it is congested by some external device - microwave oven, or IP camera can also take whole channel.

what NIC and driver version are the clients using?

Keep in mind that windows update does not update the wireless drivers.

HTH,

Dear Stephen,

There is a MIX of clients, Lenovo, Dell and HP, but everyone has same problem.

But what is the wireless NIC. Is there a common chipset?

Intel, Broadcom etc

HTH,

Steve

Dear Steve

The most common chipset is Intel.  What is your recomendation whit it?

[Stephen Rodriguez]

my recommendation would be to grab the latest drivers, and build an MSI package that you can push to your clients with a GPO, and install the latest drivers.

HTH,

Steve
