Model: Omada Software Controller (Linux)   EAP650   EAP613  
Hardware Version: V5
Firmware Version: 5.15.24.19

Hello,

I have disabled DFS channels from my Omada Controller settings. After that, I rebooted all access points and devices. However, the APs are still holding on to DFS channels instead of switching to the allowed ones.

 

I would like to know why this is happening and if there is any additional step required to completely stop using DFS channels.

 

Details:

 

Controller: Omada Controller (5.15.24.19)

 

AP Model: (Eap613.610.650.653)

 

Firmware Version: (V1)

 

Has anyone else faced this issue, and what is the solution?

 

Thank you.

Hi  @MDRAJU 

 

The following is an explanation of the DFS feature.

With the DFS function enabled, the devices will monitor the frequency they are using for radar signals. If radar signals are detected on the current channel, the devices will automatically vacate that channel and switch to an alternate channel. Additionally, the channel on which radars are detected will not be used for a period of time.

 

Turning off this function only means that when the AP operates on DFS channels, it may not automatically switch to non-DFS channels - it doesn't mean the AP won't use DFS channels at all.

If you want to avoid DFS channels completely, we recommend setting channel limits (Config > Radios >5G) to manually exclude those DFS channels.

are you using 160mhz width on 5ghz ?  if so, it has to use the entire 38-64 spectrum
