RNDIS USB Modem Dongle is not working after installing Windows 10 Fall Creators Update

Hi,

Updated 1/31/18:

A fix for this issue was included in the January 31, 2018 Windows Update (KB4058258).  If you are experiencing this issue, please install the latest Windows Updates.  

If the issue continues after installing the update, you may need to uninstall and reinstall your Remote NDIS network adapter using Device Manager:

1. Open Device Manager.  To do this, press and hold (or right-click) the Start Menu icon and select Device Manager.
2. Expand Network adapters and find an entry for the Remote NDIS based Internet Sharing Device.
3. Right click Remote NDIS based Internet Sharing Device and select Uninstall device.
4. Select Network adapters and then select Action and then Scan for hardware changes.

Note:

• Ensure that the RNDIS device is plugged in on the PC's USB when performing these steps.
• If the RNDIS device is moved to another USB port, these steps will need to be repeated.
