Your post is from November 9th. It doesn't even address my 4G question, much less answer it.
Sorry, mine doesn't have an internal 4G wifi adaptor so I didn't notice that part. Maybe the question needs to be, what hardware is it precisely, and has anyone got similar hardware working, maybe via an external dongle.
The internal "standard" wifi is dealt with however. Maybe someone else may be able to help. Try a question specific to that part of the hardware in the networking section.
