I am using the default wifi app, have initialized the drivers using the script and then assigned passphrase and security protocol to the interface, I can connect to the wifi AP but the dcs is unable to find a valid channel for this which is preventing AirVantage connection to the server.

Where this sounds like a bug to me when it says technology 1 but name it cellular while this should be wifi.
I believe these two are the key points:

Once the wifi client is started and connected, the dcs service cannot find the channel in the database, so I assume I haven`t setup this properly?
Or it should be something handled by the wifiClient itself and possibly a bug?

Wifi is working so I don`t this has anything to do with the drivers, but likely with the legato.

This is how I setup the channel for the wifiService which should be aligned with the legato docs.

root@fx30s:~# config get wifiService:/
/
wifi/
channel/
TR-OFFICE/
secProtocol == 3

So this is a malfunctioning of the le_dcs api?
