Is there a way to disable Channel 12 & 13?

Hi,

 

I'm using 2 UniFi AP-AC-Pro, Version 3.9.54.9373, Non US.

I've installed them a few weeks ago. Everyting works fine, channels are set to AUTO, because the 2.4Ghz is heavely used here, So the system can switch if needed.

 

Now, I have several devices that only work on channels 1-11, and as soon as the system switches to Channel 13, those devices loose connection.

 

Is there a way to limit the channels to 1-11? I don't want to use a fixed channel, as I'm loosing the flexilility of the system then.

 

Erwin

Hello @ErwinFiten,


Welcome to the community!

 

The Channel only change on a UAP reboot/restart.

You can't exclude those channels.

 

I highly recommend using static radio settings

Devices > UAP > Config > Radios

 

2.4 GHz
Channel width: HT20
Chanel: 1/6/11 | Choose one of these channels, a RF scan will help you choose the most clean one.
Transmit Power: Low/Medium

5GHz
Channel width: VHT40 | Optional VHT80 might decrease wireless stability
Chanel: 36/44 | Optional (149/157) Choose one of these channels, a RF scan will help you choose the most clean one. Avoid using DFS Channels
Transmit Power: Medium/High

Thanks for the fast reply.

With Wireless networks, I have enough experience, I know I have to avoid DFS channels as there is a military radar about 5 miles away, and a civile around 10 miles away.

 

For now, I set the 2G signal to channel 6 , and power to AUTO.

on 5G I leave it all on AUTO, and set the bandwith to 40 (was on 80, because I'm the only one using 5G user in the neighborhood, so I was thinking to maximize bandwith

 

Is there a disadvantage if I leave the pwoer to AUTO ?

Hello @ErwinFiten,

 

AUTO is HIGH, you don't want your UAP to be screaming while your clients cant answer back.
