Changes

 * Introduced a new mobile broadband driver based on the Net Adapter framework, which was first introduced as a preview version in Windows 10 Creators Update. If the PC supports cellular connectivity, you can switch to this driver by following these steps down below.


 * 1. Make sure the PC can support ways of connecting to the cellular network, such as SIM cards and USB modems (either over the internal USB bus or by using a USB dongle)
 * 2. Setup cellular connectivity.
 * 3. Choose the new Net Adapter MBB USB class driver as the default driver. This can be done by opening Device Manager (easiest way to access it is by right-clicking on the Start button). After opening Device Manager, go to the Network adapters section and then choose Generic Mobile Broadband Adapter or xxxxx (xxxxx being whatever the device is branded as) Mobile Broadband Adapter.
 * 4. Right-click the selected driver and then select "Update driver", on the box that comes up, click on "Browse my computer for driver software", then click on "Let me pick from a list of available drivers on my computer", then choose 'Generic Mobile Broadband Cx Net Adapter '. After selecting that driver, click on Next to install the driver, and then reboot to make the new driver take effect.
