What if the WIN7/8 wireless network connection is restricted?

First, check the network and router signal is unblocked

First of all, verify that the network is not a fee, the wireless router line connection is good, wireless network signal launch is normal.

If you determine the problem with the router, you may wish to reboot the router or restore the router's settings to factory status.

Also, if you can, update the wireless router firmware and the computer's wireless network adapter driver for the latest version.

　　Second, check Network service status

Press Winkey+r to start the run, and type "services.msc" to start the Service Management window. Verify the status of network services, such as DNS client, DHCP client, and IP helper (default is on), and then restart the computer.

　　Third, check the IP address and DNS server address

1. Right-click the wireless network icon on the right of the taskbar and choose Open Network and Sharing Center (also available in the Control Panel).

2, in the Network and Sharing Center window, click to view the active network state on the right side of the "connection."

3. In the WLAN Status window, select Properties.

4. In "This connection uses the following item", double-click Internet Protocol version 4 (TCP/IPV4).

5, confirm the required IP address and DNS server address input is correct, after the change is completed, press "OK" exit (the default is automatic acquisition). For a wireless network that has a binding IP address and DNS server address, enter the specified IP address and DNS server address.

　　Iv. using the system's built-in diagnostics tools

The system's own wireless network diagnostics function is very good, it can locate network problems and give partial repair.

To enable the diagnostic tools built into the system, simply select Diagnostics in the above WLAN status window and then follow the steps.

　Five, reset network connection

Run the command prompt as an administrator and enter the following command:

NETSH INT IP RESET

NETSH WINHTTP RESET PROXY

Ipconfig/flushdns

After each line is finished, press ENTER to confirm that the network connection can be reset after the execution completes.

　　Six, reset Winsock

The Winsock key value in the registry has been mistakenly deleted, resulting in limited network connection prompts, so backing up the registry is just in case when the network is normal.

Position of Winsock key value:

Hkey_local_machinesystemcurrentcontrolsetserviceswinsock

Hkey_local_machinesystemcurrentcontrolsetserviceswinsock2

You can also use the command prompt (run as an administrator) to reset winsock:netsh Winsock reset
