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

I assume then having tested beta versions, all newer 10.41 versions do not resolve the issue...

Interesting, I had to downgrade the controllers before it allowed me to downgrade the AP. anywho, controllers and APs all running 10.41.06 until further news.

Is there any update with this issue? Seeing this also.
Think this issue exists in 10.41.09 as we jumped from 10.41.06 and experienced this.

If you are still running into issues I would suggest contacting the GTAC for assistance: https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-contact-Extreme-Networks-Global-Tec...

OK let's do that step by step....

Is that the same SSID for 5GHz and 2.4GHz ?

Per the describtion the clients on the 2.4GHz are connected to the SSID but get no IP.
- are they authenticated = if you check the client/SSID report to they all have the green lock in the first row
- who is the DHCP on that network, is it the controller or a ext DHCP
- does the communication work if you set one client with a static IP
