NWA50AX PRO 160mhz

Hi @rossano,

After checking, your AP didn't keep in 160 MHz because the AP detects radar. Once radar is detected, the AP must change to 80MHz to avoid radar channel because the original service channel can’t be used per regulatory requirements.

If there are often radar signals in the environment, switching to another channel and using it at 160MHz will not be implemented forever, because the radar channel will still be covered. AP will switch to a non-DFS channel and remain there for 30 minutes.

If no radar is detected within that timeframe, the AP will resume using the DFS channel and potentially return to 160MHz bandwidth. However, if radar is still detected after 30 minutes, the AP will stay on the non-DFS channel, with the maximum channel width is 80 MHz.

Hi @rossano,

Apologize for the delay.

 Maybe is because the 160 MHz is so wide that goes in a DFS channel?

Yes, that is the reason. Please reference the screenshot below to find the related channels for each channelwidth.
