Change Power Management Settings

Uncheck the IPv6 box

• Click on Change adapter settings (in the left pane).
  Right-click on the connection you‘re using. Click Properties.
  Now remove the tick from the IPv6 and click OK to save changes.

Use Network troubleshooter

• Right click the network icon in the bottom right corner. Choose Troubleshoot problems from the menu.
• Network troubleshooter will now start and try to fix your problem.

Using Device Manager

• Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.
