Re: Power level of AP changing when we are rebooting AP

subodh goyal · ‎08-02-2023

I want AP to have power leve3 so i have selected Transmit power to 3 under Tx Power Level Assignment
but when AP is rebooting it is again changing to 4 and showing as global. Images attached.

Can anyone please confirm what can be the issue?

- Did you save the configuration on the controller after making changes ?

Yes, i have saved a configuration

- As far as it might be related to buggy behavior , use a recent software version on the controller : 17.9.3 or above , if applicable ,

WLC is running with latest software version 17.9.3

- It probably won't help but a configuration check could provide insights , use CLI show tech wireless ; feed the output into : https://cway.cisco.com/wireless-config-analyzer/

Have you got "ap tag persistency enable" configured?
