Several issues needing attention in the connection setting of wireless card

Wireless Card Installation factors

The first factor that affects the wireless network card device connecting to local wireless networks is the working state of the wireless card device itself. In order to ensure that the wireless network card equipment itself stable quality, we should be concerned about the installation of wireless network card equipment, because the quality of the wireless network card equipment, if not properly installed, light will not be able to play the wireless network card equipment work potential, heavy will cause the wireless network card equipment can not work. When installing the wireless card device, we sometimes see the screen blue screen error, when encountering this error phenomenon, we should first carefully look at the current use of the wireless card driver is suitable for the local workstation operating system.

For example, if we use a wireless card device driver is only suitable for use in Windows 2000 system environment, but now we force the driver to use in the Window XP system environment, then the system blue screen error may be relatively large, even if the blue screen error does not occur, This kind of wireless card device can not be installed to work efficiently.

Therefore, when installing the driver for the wireless card device in the local workstation, we must see if the driver of the device can be used in the system environment of the local workstation, and if not, the wireless network card driver for the local workstation system should be found online. In some workstation systems, we also sometimes need to pay attention to the installation order of the wireless card device drivers, if the sequence is wrong, the workstation system may not recognize the wireless card device.

For example, sometimes we need to install the driver of the connection interface, after installing the driver of the network card device, and then inserting the wireless card device into the workstation system, once the installation sequence is confusing, the wireless card device may be installed unsuccessfully, which will affect the normal Internet access of the wireless station, Block unlimited workstations from connecting to local wireless networks.

Of course, before installing a driver for a wireless card device, we should check that the wireless card device is in good contact with the local workstation, for example, you can check that the wireless card device is securely plugged into the corresponding interface or slot in the local workstation. See if there is a loose connection between the wireless card device and the local workstation.

If we arbitrarily remove the wireless card device from the Workstation motherboard USB interface or PCMCIA interface, and in a very short time to plug in, it is also very easy to cause the system screen blue screen error, or when the wireless network card signal is flashing state, If we suddenly unplug the wireless network card device from the local workstation, it is also prone to blue screen errors, and can even damage the interface of the wireless card device or the interface of the local workstation.

In order to effectively avoid this phenomenon, we in the future when plugging the wireless card device, try not to do in the workstation system related to network access operations, and for security purposes, as far as possible through the System Device Manager to disable, uninstall the wireless card device.

After confirming the successful installation of the driver of the wireless card device, we also need to set the working parameters of the wireless network card device as appropriate; For example, we should go to the Wireless Connection Properties Settings window and set the IP address of the wireless card device to be in the same subnet as the IP address of the wireless node device in this Setup window. , which makes it easy for wireless card devices to search the local wireless network efficiently and quickly.

　Wireless Internet setting factors

If the wireless station's Internet parameters are not set correctly, then the wireless station will not be very smooth connection to the wireless network, so to ensure that the wireless station can be very smooth connection to the local wireless network, we need to carefully check the wireless Internet setting factors.

When the wireless internet setting factor is checked, we should first log in to the wireless workstation system as a privileged identity, click the Start/settings/Network Connection command in the system desktop, and in the list of network Connections pop-up window, right-click the target Wireless network connection icon. Open the Wireless network connection Properties Settings screen by clicking the Properties command from the popup's right-click menu.

Click the General tab in the Settings screen, select the TCP/IP protocol item in the corresponding option Settings page, click the Properties button under the item, and in the Settings page that appears, look at the IP address and mask address of the local wireless card device. If the address of the wireless node device is in the same subnet, and if it is not correct, we should adjust it correctly in time.

Next, click the Wireless Network Configuration tab, and in the option Settings page, see if the local workstation can search for and display the node name of the local wireless network correctly. If the SSID name cannot be searched, we can fill in the SSID name of the local wireless network directly by manual method, then click the "Properties" button, go to the "Association" option settings page, check the "service Name (SSID)" in which the information is the same as the local wireless network.

Finally find the "Wireless network key" setting item and see if the "Data encryption (WEP enabled)" parameter in this setting item is activated properly, and if it is found to be activated, we will also see if the encrypted content entered in the "Network key" text box is the same as the encrypted content of the local wireless network. If we find that it is not the same, we should revise it in time.

　　Wireless signal interference factors

If the wireless station's Internet access signal is disturbed by the external signal, or the signal transmission distance is very far, the wireless station can hardly connect the local wireless network quickly, so we need to find ways to eliminate external signal interference, adjust the communication distance between wireless station and wireless node device, Also wireless workstations a good working environment. Once we do not search the local wireless network node name in the wireless network connection properties interface, we need to carefully check the wireless card and the wireless node device, whether there is some kind of signal interference source.

For example, we can look at wireless workstations or wireless node near the device, there is no similar to TV, refrigerator, air conditioning and other high-power household appliances, or to see if there are similar to cordless phones, mobile phones, such as common communications equipment, these devices can often be transmitted to the wireless network signal transmission caused serious interference, If these sources of interference are found, we must eliminate them in a timely manner, or transfer wireless workstations or wireless node devices to a four-week vacant location to ensure that wireless Internet access is kept away from interference from various sources.

In addition to the external interference source will cause interference to wireless internet, wireless signal transmission distance will also affect the "hand" wireless network stability and success rate. Generally speaking, the communication distance between the wireless card device and the wireless node device should be controlled within 100 meters, after which the wireless signal is easily attenuated during transmission, which will affect the speed of searching the wireless network, and can not even search the nearby wireless network. So we can try to adjust the distance between the wireless station and the wireless node device when we find that the wireless station is not able to "hand in" the wireless network nearby.

　　Wireless Node Self factor

After excluding the above factors, if the wireless station is still unable to quickly search the local wireless network, then we need to look at the local wireless node device, because the device is the core of the wireless network, once the device is not working properly, or the setting error, It will also prevent the wireless workstation from connecting to the local wireless network successfully, so we should finally look at the wireless node device itself if there is a problem.

Let's say we can try to restart the wireless node device to free up cache space in the device, or try to restore the device's operating parameters to its default values, or try changing the antenna position of the wireless node device. If the above measures do not allow the workstation to successfully connect to the local wireless network, we can consider the use of good performance, hard-quality wireless node equipment to replace the existing equipment, I believe that this will allow wireless workstations to quickly connect to the local wireless network.
