Five reasons and solutions for wireless network connectivity

The five main reasons and solutions for laptop wireless network connectivity: the development and popularization of wireless networks in particular, wireless LANs enrich our lives and make our lives more and more convenient. At the same time, provide High-speed and high quality Network service. Due to the unique de property of wireless channel. Makes the wireless network connection unstable. The quality of the service is greatly affected. Do you often encounter a laptop that is not connected to a wireless network? While other laptops are normally connected to the de situation. Today. The author takes the Flying Fish star router as an example to introduce the reason and the solving method concretely.

　　First, start blending mode

Set no lines from the rear. If the new de notebook (11n wireless network card) can be connected to the wireless network. The Old de notebook (11g wireless network card) could not be connected. It is possible that the wireless router will set the wireless mode to 11n mode. Then 11g and 11bde wireless network card Naturally cannot access wireless networks.

Enter the wireless router Deweb configuration interface. Set the network mode to 11b/g/n blending mode. So no matter what standard de wireless card you use, you can easily connect to wireless networks.

　　Second, set to automatic channel matching

The General wireless network card de Channel settings range is 1-11. And the wireless router de channel settings range is 1-13. If the wireless router de channel is set to 12 or 13. The Natural wireless network card cannot connect to the network.

Enter the wireless router Deweb configuration interface. In the wireless Settings--> Wireless Channel Select 1-11de arbitrary frequency band. This wireless network card can be connected to wireless networks. The recommended option is automatic selection. The wireless network card automatically selects the channel. Eliminates the user to set de trouble.

　　Third, update the operating system version

Use the de operating system too old de word. Although the system does not affect the wireless network card on the surface. In practical applications you will find that even if you choose a 11n wireless network card. Some WPA or WPA2 encryption methods de wireless networks are not connected. Windows XP supports the WPA and WPA2 protocols after a SP1 patch has been played. In practical application, there are some problems in the SP1 of wpa/wpa2de compatibility. There will still be an inability to connect to the de situation.

Upgrade the operating system. Either Windows 7, Vista, or XP SP3. They provide good de support for WPA and WPA2 protocols. Ensure that your de wireless network card can easily connect to the WPA/WPA2 encrypted network

　　Four, the notebook wireless card is too old

Part of the old notebook user. Because the laptop card is too old. This NIC may only support IEEE 802.11B standard and WEP encryption protocol. But the current mainstream DEWPA and WPA2 encryption protocols are not supported. If Use de is this kind of wireless network card. Although you can search for a WPA or WPA2 encryption de wireless network in the wireless networks list. But you can't connect to these wireless networks. Because you de wireless network card does not support the latest de encryption protocol. The built-in de wireless card will often be blocked by the encryption protocol de and unable to connect to the network.

There is an urgent need to use wireless networks. You can temporarily reduce the use of cryptographic protocols such as WEP. The most effective de solution is to change a new de built-in/external wireless network card. It is best to support the 802.11n standard.

　　V Wireless network switch and shortcut keys

In order to reduce power consumption. Many new laptops have designed wireless networking switches. In the default de case is turned off de; some wireless switches are also designed to be hidden. It's hard for users to find them.

Many notebooks design shortcuts (typically Fn+f5). The wireless network card can be started only if the shortcut key is pressed. The wireless switch is only available to connect to the wireless network normally.

All of these five reasons may affect the computer not connected to the wireless network. Everyone in the problem when the specific problems must be specific analysis, the right remedy, in time to deal with the problem!
