Solutions for computers that cannot link routers

Several solutions for computers that cannot link routers

First, turn on the mixed mode set without line, if the new laptop (11n wireless network card) can be connected to the wireless networks, the old notebook (11g wireless network card) is unable to connect, it may be the wireless router to set the wireless mode to 11n mode, then 11g and 11b wireless network card is naturally unable to access wireless networks.

First, open mixed mode

After setting no lines, if the new laptop (11n wireless network card) can be connected to the wireless networks, the old notebook (11g wireless network card) is unable to connect, it may be the wireless router to set the wireless mode to 11n mode, then 11g and 11b wireless network card is naturally unable to access wireless networks.

Enter the wireless router's web configuration interface and set the network mode to 11b/g/n blending mode so that no matter what standard wireless card you use, you can easily connect to the wireless network.

Second, choose automatic channel Matching

The General wireless network card channel setting range is 1-11, and the wireless router's channel setting range is 1-13, if the wireless router's channel is set to 12 or 13, the natural wireless network card cannot connect to the network.

Access to the wireless router Web configuration interface, wireless set--> wireless channel to choose 1-11 of any band, so that wireless network card can be connected to wireless networks, the recommended choice of automatic selection, wireless network card will automatically select the channel, eliminating the trouble of user settings.

Third, wireless network switches and shortcut keys

In order to reduce power consumption and increase the endurance time, many new laptops have designed wireless network switches, which are turned off by default, and some wireless switches are designed to be hidden and difficult for users to find.

Many notebooks design shortcut keys (generally for fn+f5), only after pressing the shortcut key to start the wireless network card, only to open the wireless switch, in order to properly connect wireless networks.

Four, operating system version is too low

Using the operating system is too old, although the surface of the system does not affect the wireless network card, but in the actual application you will find that even if the 11n wireless network card, there are some WPA or WPA2 encryption mode of wireless networks can not connect. Windows XP after the SP1 patch will support the WPA and WPA2 protocol, in the actual application SP1 to WPA/WPA2 compatibility or there are some problems, still can not connect the situation.

upgrades to the operating system, whether Windows 7, Vista, or XP SP3, provide good support for the WPA and WPA2 protocols, ensuring that your wireless network card is easily connected to the WPA/WPA2 encryption network.

Five, the notebook's wireless card is too old

Some old notebook users, because the laptop card is too old, this NIC may only support the IEEE 802.11B Standard and WEP encryption protocol, but does not support the current mainstream WPA and WPA2 encryption protocol. If you are using this type of wireless network card, although you can search for WPA or WPA2 encrypted wireless networks in the wireless network list, you cannot connect to these wireless networks because your wireless network card does not support the latest encryption protocol, and the built-in wireless card is often blocked by the encryption protocol and cannot connect to the network.

Wireless networks are urgently needed, and the most effective solution is to temporarily reduce the use of cryptographic protocols (such as WEP) by replacing a new built-in/external wireless network card, preferably with the support of the 802.11n standard.

The above five aspects will affect the computer is not connected to the wireless network, everyone in the problem must be carefully analyzed.
