Do you still see the same issue when you connect the endpoint to a wired network ?

also share output for “show client detail mac_address_of_effected_client” from WLC

Can you provide more info? You sure you don’t have a duplicate address issue or a misconfiguration? Is this a new setup or was this working fine and then started to fail?

Can you paste output for one of the connected client as asked before, also based on your response to Scott seems like this is a new issue which happened just today, are you aware of anything that changed recently?

hey @Leo Laohoo

the troubleshooting that i did

at the time of disconnection

wireless client : can't ping neither the gateway of vlan wirelss nor le WLC or any other ip address

wired client : i can ping the gatway of vlan wireless and the controller

i get always disconnection in wireless network

Well, if the wireless client is disconnected from the WLAN, why would it be able to ping any IP address when it doesn't have an IP address?

Create an SSID with open authentication. Make sure the SSID is using the same dynamic interface. See if this problem occurs with an open SSID.

Can you run a debug when this issue is occuring?

You still need to provide more info. Did anything change, since you said it worked before, is the issue with one or all devices including phones or different model laptops? Did you look at your radius logs?

Thanks for the output, just curious where are you physically located, since your client is connected on channel 13
