David Frey posted this in the mangoh forum November 2017:
I talked to a couple people on the Legato team and they mentioned that the reason you cannot connect to AirVantage using the ethernet connection on the mangOH Green is that the ethernet connection isn’t supported by the data connection service. The data connection service is responsible for establishing a data connection to the internet on demand. This is a known issue and there is some interest internally in improving the data connection service to support this feature. I don’t know when it might happen though.
Is there any news on this topic?
I did some tests with legato 20.4 and le_dcs but it still tries to start a new cellular connection even though I have an active ethernet connection.
