In an attempt to isolate problems with my D-Link DWR-921 version C3 and the LTE connection with QMI, I'd like to start from scratch with a clean install and configuration.
I need Image Builder to add to the image at least the needed packages to connect to the internet.
These look likes needed packages:
To send AT commands these are suggested packages
but what about the followings? do I still need them given the modem is not USB dongle but integrated in the router?
I’d like also to automate the first configuration of QMI, VPN, Firewall, etc
I saw somewhere a github page with a kind of script to automate the configuration but I’m not able to find it again, do you know something similar?
PS: see this 3d for reference on the issues related to this router:
