AP Channel selection with no Radio Resource Provision

Hi guys,

 

I know if I enable Radio Resource Provision under FortiAP profiles, the APs will scan the frequency range and select the channel with less interference between the other APs, this is well documented in Deploying Wireless Network Guide.

But what happens if this feature is not enabled? I have several APs working with this feature disabled:

 

 

The APs have selected a channel, some on channel 1, some on channel 11... Do you know what the criteria or algorithm is for this channel selection?

 

Regards,

Julián

    My understanding is that when an AP initially boots up , it automatically does a scan of the environment and based off of that, selects a channel (unless the channel was manually configured). If the "radio resource provision" feature is enabled, it will continue to do this type of scan periodically (by default, every 30 mins). You can adjust the frequency of how often this scan is done via the CLI:

    Hope that helps!

    Hi everyone,

     

    Has anyone hands-on experience with the "Radio Resource Provision" feature? I have enabled this feature for my FortiAPs but they are changing the channels very often. Is this normal behaviour? Do the FortiAPs change channels when they have clients associated?

     

    Regards,

    Julián
