After installing the Windows 10 Fall Creators Update (Build 1709) on my PC, all my network connections–whether wired or wireless–were broken. When I checked device manager I had a exclamation mark against all but one network device. The only device excluded from error was the “Check Point Virtual Network Adapter”.
Going into the properties of one of these devices gave equally cryptic errors. All devices reported the same thing.
Windows is still setting up the class configuration for this device. (Code 56)
A couple extra reboots did not resolve the odd error either.
A quick search on the internet revealed forum postings that identified the Check Point VPN as the culprit (credit SOHIC for the answer). This made sense as the version of the Check Point software I had made no mention that it was supported on Windows 10. My bad!
But this was the key. When I uninstalled the software, and rebooted, all my network connections came back to life.
Uninstalling the Check Point VPN
The process to uninstall the Check Point VPN is as simple as uninstalling any other software. To do this, click on your Start Menu and start typing “control panel”. Select Control Panel from the search results to launch the control panel.
From the control panel click Programs and Features.
Under the Uninstall or change a program dialog select Check Point VPN and click Uninstall.
Click Yes when prompted to confirm the uninstall. This install should only take a few seconds.
At the end of the install you will be prompted to reboot. Save and close any work you have open. Click Yes to restart your machine. Otherwise click No to restart later.
Upon restart your network connections should be restored.
