IdentiFi: 2.4Ghz clients unable to get IP

Ilya_Semenov — Thu, 09 Aug 2018 14:02:00 GMT

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,

Is there anything in the controller logs? Any mention of anything major going on, any significant interference in the 2.4GHz spectrum etc?

Just to check, are the 2.4 Radios enabled still, and if there are SSIDs unique to the 2.4 spectrum are they still visible?

I've seen this the other way around (on 5GHz when local RADAR caused an issue) but not site-wide for 2.4 unless something has been changed globally.

Assuming the 2.4 radios are still on, are you using auto RF parameters or hard-coded channels and power? Has anything changed there, dropped down etc? Might be handy to look at one of the inventory reports to give you a breakdown of all APs and their 2.4 and 5GHz settings per AP for peace of mind.

Is there an authentication mechanism in the background after the controllers that might be stopping something here? If just PSK, and its an SSID unique to 2.4, has the key changed/still what you'd expect it to be? Could it be a DHCP lease issue (no IPs left, DHCP server problem etc?)

Thanks

Rob

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

Umut Aydin

Hi, Umut,

SW 10.41.07.0014

All SSID affected.

This is what I have in log:

Hi, Umut,

are 11k/MFP/fast Transistion settings disabled? I don't know where to check MFP and Fast Transition.

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ronald_Dvorak — Thu, 09 Aug 2018 14:41:00 GMT

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)

Ilya_Semenov — Thu, 09 Aug 2018 14:41:00 GMT

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.

Ronald_Dvorak — Thu, 09 Aug 2018 14:42:00 GMT

Is that the same SSID that works for 2.4GHz & 5GHz and not even one client works on 2.4GHz ?

Do you use the load group feature on this SSID.

Umut_Aydin — Thu, 09 Aug 2018 14:42:00 GMT

It should be ..What version do you use ?

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ilya_Semenov — Thu, 09 Aug 2018 14:42:00 GMT

Hi, Ron,

I've no idea what is it - Load Group Feature.)

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ilya_Semenov — Thu, 09 Aug 2018 14:42:00 GMT

Ronald, I wasn't right. There is a Load Group exists. I've deleted it. Wait for a result.

Ronald_Dvorak — Thu, 09 Aug 2018 15:08:00 GMT

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

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ilya_Semenov — Thu, 09 Aug 2018 15:08:00 GMT

This is the same SSID.

We have external DHCP.

I'll check static IP and let you know.

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.

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ian_Broadway — Sun, 12 Aug 2018 22:29:00 GMT

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.

RE: IdentiFi: 2.4Ghz clients unable to get IP

Ian_Broadway — Sun, 12 Aug 2018 22:29:00 GMT

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

Hi All,

Are Extreme able to provide an update to this issue?

No mention of a fix in 10.41.12.
