I’ve got a Fujitsu Lifebook E752 with an MC7710 mini-PCIe wireless module.
In principle, things should be simple to get working, however, none of the drivers I am installing (neither from Fujitsu nor from Sierra itself) actually seem to work for my modem, despite it reporting to the computer as MC7710. The drivers say they’re supposed to work on windows 10, so that’s not it either
I’ve verified that beforehand, while it fails to connect to a mobile network, it definitely gets recognized, and as with windows, I think this is just a question of finding the right drivers.
Linux also recognizes it as an MC7710, so if there is a fault with the module, it’s not apparent right away.
