How to solve the alternate channel width warning?

Whenever an Access Point reports a WiFi radio operating on an unsupported channel width, the Plasma Cloud will warn you and activate a fallback configuration. 

Replace warning after API flag has been implemented

What does it mean?

When a network is configured with a certain radio channel width that is not compatible with an Access Point within your network, or is legally not permitted in the country where your devices are deployed, this warning depicted above is shown.

The Plasma Cloud Console will automatically select a compatible WiFi channel width to ensure the affected Access Point can continue to operate normally. You can see which channel has been auto-assigned via the Access Point table in the 'Channels (width)' column.  

What to do?

There are three ways to resolve this issue:

Automatic Configuration

It is strongly suggest to enable the WiFi AI in your network. This useful tool will automatically pick the best channels for each device in your network and ensure optimal performance. To learn how to activate the WiFi AI, please see this article.

Manual Configuration 

You can also manually configure WiFi channels width on both the network and Access Point level.

Network level:

Please note that not all WiFi settings are supported by every device model. Therefore, it's possible to configure network-wide WiFi settings that are compatible with some devices but incompatible with others in your network. For example, 160 MHz wide channels are only supported by WiFi 6/6E models. Either pick WiFi channel widths that work across your entire network, or assign unique WiFi channel widths to individual Access Points by overriding the network default settings. 

To learn how to configure WiFi settings for your entire network, please see this article.

Access Point level:

Here you can override the Network WiFi settings and create an individual configuration for your selected Access Point. The Access Point details page only provides compatible channel width options based on legal requirements and device capabilities.
