One, unable to network may be a DNS setup issue
1, right click on the computer taskbar "open Network and Sharing Center"-"Ethernet"-"Properties"-"Internet Version Protocol 4" and "Internet Version Protocol 6" We will see IPv6 is selected, we cancel it.
2, okay now we close the front window press the "Win key +x" key to open the menu, select "Command Prompt (Administrator)", and then enter "netsh" + return, and then enter "WinHTTP" + carriage return, this time to restart the computer to see if the application store can be successfully connected. This approach is typically a problem for browsers being changed.
Enter the command character to resolve
3, the same right click on the taskbar in the lower right corner of the network icon found in the bit of "Ethernet"-"Internet Version Protocol 4" and "Internet Version Protocol 6", The DNS addresses are then manually changed to 8.8.8.8 and saved, or changed to 114.114.114.114.
Second, maybe the Internet may be a proxy problem
1. We press "Win+x" at the same time on the computer desktop
2. Then after the pop-up run box entered Netsh, we click Add Car.
3. Wait for completion of the above execution after we enter WinHTTP, carriage return;
4. Enter the import proxy source=ie and press ENTER to confirm the operation.
All right, after three steps, we'll reboot the computer and see if we can open the App Store.
