Apsaradb for Wireless AP network troubleshooting

We have already introduced many wireless network technology application technologies. How can we solve this problem for many of our network users? Here is a detailed introduction.

A Wireless AP can theoretically connect to 254 computers, because different SSID (WEP password can also be set) is set to prevent malicious intrusion into our account. However, if you find that the network connection is abnormal after the installation, you do not want to see it. Today, we will provide you with tips to solve these problems.

① Test the signal strength. If you can Ping an access point from a wired client but not from a wireless client, the access point may be faulty. You can use the measure signal strength function provided by the Wireless AP program to check the signal strength. If it is too weak, the Wireless AP may have quality problems. If it is caused by poor signal status (the Signal status can be detected using the software included in Windows XP "wireless network connection" or "Wireless Access Point ).

When using Windows XP, you only need to click the network connection icon in the taskbar to display the connection status window. If four or five green lines are displayed, if only one or two lines are displayed, the signal status can be determined to be poor, and the placement position and antenna angle of the AP and wireless network card can be adjusted, to achieve the optimal signal strength.

② Try to change the channel. If you suddenly find that your Wireless AP signal is weak, but you have not made any physical changes. You can try to change the Access Point and the channel of a wireless user or add an external antenna to see if the signal can be enhanced. Because some new wireless phones (or microwave ovens) are also running at a GHz frequency (using 802.11b wireless networks at the same frequency), this may interfere with your wireless network.

③ Check the SSID configuration. When you join other wireless networks, do not forget to change the Service Set Identifier configuration. If the SSID configuration is incorrect, you cannot Ping the Access Point or connect to the network.

④ Check the WEP Key. Many wireless network configuration problems are related to the WEP Protocol. To solve the WEP problem, we need to be very careful. In addition, If WEP is required to take effect, the Access Point and client configuration must be correct. Some clients seem to have no problem in configuration, but they cannot use WEP to communicate with the access point. In this case, you can restart the access point, restore the default value, and then re-configure WEP, then WEP can be used.

⑤ Right-click the Wireless Network icon in the taskbar. Select the "view available wireless networks" command in the next menu, and you will see the wireless network connection dialog box. The dialog window shows any SSID on your current channel that you are not connected. If your wireless network name appears in this list, you are not connected to the network. If your connection is good, your configuration may be faulty. In addition, you must enter the correct WEP password (if any). Otherwise, you cannot connect to the wireless network.
