What if Win8.1 wireless network is restricted?

First, check the network cable

This is also the most special, most embarrassing situation. It's also easy to troubleshoot, open the Control Panel, select Network and Internet, and check whether Wlan or Ethernet is connected.

Ii. Retrieve IP address information

When the network is still unable to connect after the cable failure, this is what we need to see the IP address of this computer, whether properly allocated. Win8.1, use the combination key (win+x), select the command character (administrator), enter ipconfig, to view.

If the following situation occurs or the IP address begins with a 169, this means that the NIC does not get the correct IP

If the user obtains the IP address of the Internet through the DHCP LAN way, can use the ipconfig/release command to release the existing IP address information, ipconfig/renew obtains the suitable IP address from the DHCP.

Third, diagnose network connection

Under the Win8.1 system, you can use Windows Network Diagnostics to examine the cause of some problems. Open Control Panel, select Network and Internet, view the properties of Wlan or Ethernet, click Diagnostics and go to Windows Network Diagnostics for inspection.

If you check for related issues, you can fix them according to the problem you found.

Four, network card driver too new or too old

This needs friends to do their own troubleshooting, drivers are generally issued by hardware vendors, and through the Microsoft Certified Network card driver.

V. Network operator issues

When we enjoy the Internet services provided by operators, don't forget that sometimes the reasons for not being able to surf the internet are part of the carrier.
