Few Extreme 3805i Access Point reboots frequenly

Few Extreme 3805i Access Point reboots frequenly logs are as below :

what could be the reason, few users disconnect frequently with limited access on ssid.......users still remain connected to the ssid with IP address, but no internet access and cannot ping their gateway, once if manually disconnected from ssid and connected back then everything works fine. same thing repeats every 10-15 minutes.

You are already having latest firmware. Extreme gtac says all issues are resolved with 9.21.7.X . I am also surprised , I am in process of upgrading to 9.21.7 from 9.21.5 but after hearing from you I am stunned. Only extreme escalation can help us out.........Identifi wireless is a big let down from extreme. Still don't understand what extreme people are doing when there are many customers facing this issue. I left all hopes ....... don't know if there are any qualified people in their team to get us out of this......

Hello,
I have also face the same issue with AP 3805i, Controller C-35, "few users disconnect frequently with limited access on ssid.......users still remain connected to the ssid with IP address, but no internet access and cannot ping their gateway, once if manually disconnected from ssid and connected back then everything works fine. same thing repeats every 10-15 minutes".

We have only one dhcp server ....... ill set few ap to static and see what happens.......but users get disconnected from internet session but they stay connected to ssid...... suddenly get limited access symbol on ssid and even ping to default gateway doesnt work at that time. need to disconnect and reconnest to SSID for everything to work fine again, this repeats for almost 40 out of 100 users.

Should I add the controller ip address in Wireless Controller Search List as well in AP static configuration.

Will resetting tunnel MTU from 1500 to 1300 help in any case, i heard it will ?

Tunnel duration is how long a tunnel between AP and controller is up.
A DHCP renew never resets the tunnel duration time.

The whole behavior of your infrastructure is very strange and I've never seen such things.
If I've to guess I'd say you've a problem in the LAN.

Could it be that there is something wrong with your DHCP - do you've 2 DHCP servers and they provide the same scope - this could result in IP duplicates.
If the AP detect a duplicate he we'll get a new/other IP which resets the tunnel.

Try to set one AP to a static IP and check whether that one doesn't reset the tunnel duration time.
