Channel width

So: You are saying, if you push "25%" with 40 MHz to an AP6, it will be broadcasted to the AP6 with 25% and 80 MHz?
Can you check the local AP6 webadmin for this? 

yeah tried that see attached pictures.

Assuming 136 is the channel, the AP6 selected?

Can you check the logging of the AP6, when you export the logs in central and check what channel the AP6 selected?

because it is true, if the AP6 selects 136 with 40 MHz, it would use 138 (136+140):

But if we selected 132, it is fine.

so i have set the AP to 132 as a test but it is still showing 80MHZ as the channel when we do a wireless inspection.

And we are sure, the tool is not doing a false positive? 
Because yes, using 132 with 80 MHz means its the 138 band. But i do not see the reasoning for the AP6 to do that.

Can you check the logs like above what MHz it uses?

They are definitely Moving to the 80MHZ range. Even when manually changing the setting on the AP to the below it is still on the 80MHZ.

can you create a support case?

So there is a fix for 2.4 Ghz.

In the current MR4. Could you try it with this?

Morning, this seems to have fixed the issue on 2.4ghz but not on 5ghz 

Did you reproduce it with MR4?
