IdentiFi: 2.4Ghz clients unable to get IP

[Ilya_Semenov]

Hello, team,

I have V2110 installation and 120 3825APs. Surprisingly, 2,4Ghz clients have stopped working. They unable to get IP. 5Ghz works fine.

What could be the reason of this?

Please, help!

Many thanks in advance,
Ilya

Hi Ilya,

did you made a upgrade recently?
What FW Version do you need?

Are all SSID's affected?

I would suggest to update to 10.41.07.

Disable 11k/MFP/fast Transistion
if enabled.

We need more details.

Regards

In my case for both SSIDs Privacy is set to None. I have redirection to external portal. So, I can't check MFP/FT status.

11k is disabled - I'd see it on the screenshot = Radio Management (11k) support.

The below KT article show where to find MFP/FT (Management Frame Protection / Fast Transition)

Hi, Umut,
