Reset network interface
Sometimes you need to reset specific parts of Windows 10’s networking settings to get things working again. The simplest way to do this is with a free tool called Complete Internet Repair (www.rizonesoft.com) – tick the first four boxes and click Go!
This assumes you already have the tool; in the likely event you don’t, right-click the Start button or press [Win] + [X] on your keyboard and choose Command Prompt (Admin) or Powershell (Admin). When the command prompt window appears, type the following commands one at a time, pressing [Enter] after each:
$ netsh winsock reset $ netsh int ip reset $ ipconfig /release $ ipconfig /renew $ ipconfig /flushdns
If the problem persists, return to the main text in this feature and carry on troubleshooting.
Complete Internet Repair 5 is worth adding to any toolkit.
