Hi,
I have a 4 AP - 2 CBW 240 and 2 CBW 140. I have a problem with one CBW 240 - It changes the width of the channel itself.
It happens every few days. When width is 20 clients have low speed. Has anyone encountered such a problem?

- Check this thread : https://community.cisco.com/t5/wireless/240ac-access-point-5g-channel-width-keeps-changing-back-to-20mhz/td-p/4414550 . adding use and or configure both a syslog server and snmp trap receiver, review logs send on the syslog server when that happens and snmp traps received on the network manager software both may clarify the problem such as reporting DFS avoidance (e.g.)

The AP always has final say over which channel width it uses after assessing the environment. We've had a few previous discussions about this. Have a read through The WiSE Article Series: Wi-Fi Subtleties Explained (Channel Bonding) (cwnp.com)
You might have better results with 40MHz channels or work out which channels are the problem and avoid using them altogether.
