Reinstall network devices using netcfg –d command

Running the netcfg –d command should be the last step you try. Consider using this if the steps above don’t help to get you connected.

This command can help solve connection problems you might have after upgrading from a previous version of Windows to Windows 10, as well as fix problems where you can connect to the Internet, but not to shared network drives. It removes any network adapters you have installed and the settings for them. After you restart your PC, any network adapters are reinstalled and the settings for them are set to the defaults.

Note
To use the netcfg –d command, your PC must be running Windows 10 Version 1511. To see what version of Windows 10 your device is currently running, select the Start Imagebutton, then select Settings > System > About.

In the search box on the taskbar, type Command prompt, right-click (or press and hold) Command prompt, and then select Run as administrator > Yes.

At the command prompt, type netcfg –d, and then press Enter.

After running the command, select the Start Imagebutton > Power > Restart, and see if that fixes the connection issue.

Notes
If you run the command and receive an error referring to NetSetupDeleteObject, run the netcfg –d command until it’s successful.
After running this command, you might need to reinstall and set up other networking software you might be using, such as VPN client software or virtual switches from Hyper‑V (if you're using that or other network virtualization software).
