I need any kind of automation so that I can setup up clonic settings for many router units. It takes lot of time accessing the router web interface and upload the settings file.

Using Telnet, I've been able to setup the WiFi details easily 

wlctl set 2g --ssid XXXXXX ....

Telnet also allows setting up lan details, however I'm unable to setup an APN for the mobile network or setting up the router password.

Is there any kind of hidden command for the mobile network setup?

Thank you,
