timed out while waiting for echo response from the ap

[Kasun Bandara]

Hi experts,

 From few days, we affected with this problem. WLC 2504 and different kinds of APs are disassociated with WLC randomly.

worked well before. and no licensing issues.

Disconnecting reason is : Max re transmission reached for AP

connection failure : timed out while waiting for echo response from the ap

any help?

thanks

What code of software you running on 2504 ?

Has this been started recently ? Are these AP & WLC are on same LAN  or across  a WAN ?

Hi, Its in Same LAN. i checked the connectivity using TDR cable test in switch. that shows connectivity is OK. but AP is not registered to WLC and i have to restart the AP to get connected. this behavior is happening randomly for different APs.

WLC using 7.0.235.3.

Thanks

I suspect this is WLC code specific.

Is there any reason why you stay with 7.0 (~ 3years old code). I would suggest to move onto 8.0.120.0 if no restriction
