Authentication Issue 'eapol_timeout'

[moha27med]

We are not use Authentication servers to authenticate wireless users.

Just use only WPA 2 encryption mode to authenticate wireless users.
But we identified there are a lot of EAPol timeouts happened during the client authentication

this is the error message:
auth_mode='wpa2-psk' vlan_id='70' reason='eapol_timeout' reassoc='1' radio='1' vap='2' channel='48' rssi='55'

What would be the issue for this EAPol timeouts

Is this issue occurring from end user device or Access Point side ?

How Can we minimize this eapol timeout issue?

I will be happy for any help or hits to resolve this issue

I don't have the answers but I find it really strange that your post is almost word for word a copy of this one : https://community.meraki.com/t5/Wireless-LAN/Authentication-Issue-EAPol-Timeout-on-WPA-2-PSK-SSID/m-p/179030

But isn't EAPoL only used for 802.1X auth ?

[moha27med]

Yes because I have some problem, and there is no solution for it

EAP is for Radius auth as mentioned already, I suggest you open a support ticket if you haven't already.

I am not 100% of the cause of this. But I had this problem also. And I was able to resolve it by enabling fast roaming 802.11r. Give that a shot and let me know if that works. If your able to that is.

I was having a similar issue with a Meraki camera and enabling this resolved it, don't understand why but thanks so much for the tip, don't think I'd have tried it myself!

I am having the same issue (SSID using WPA2-PSK and clients all of a sudden showing EAPOL Timeouts, which does not make any sense), but I do not understand how enabling 802.11r could solve it, since we are using PSK. I will try it though

Did you find a solution? I seem to be having the same issue.

I selected adaptive mode in 802.11r and I didn't get any more similar logs.

[padraic5]

Did you use adaptive mode because you were having the issue with Apple devices? Has it returned for you since then?

This started happening at a few of my networks, causing issues with iPads and iPhones.

I believe I've tried toggling 802.11r (at least on/off, maybe not to adaptive), but regardless, it still happens approximately once per month. Typically all the authentication errors will be on one AP. Rebooting it resolves until it happens again 3-6 weeks later.

Which firmware are you running? Are you using WPA2-PSK, WPA3-SAE, or something else for this SSID?
