无线网络连接中常见故障解决方法（Solutions to common faults in wireless network connections）

无线网络连接中常见故障解决方法（Solutions to common faults in wireless network connections） 1., mixed wireless networks are often dropped Fault phenomenon Using Linksys WPC54G card and Linksys WRT54G AP to build wireless LAN, they use the IEEE 802.11g protocol, there are still a few 802.11b network cards in the network. 54Mb/s connections are often dropped when using WRT54G. fault analysis In theory, the IEEE 802.11g protocol is down compatible with the 802.11b protocol, and devices using the two protocols can be connected to the AP using the IEEE 802.11g protocol at the same time. However, from the practical experience, as long as there is a network card using the IEEE 802.11b protocol in the network, then the speed of the entire network will be reduced to 11Mb/s (the speed of the IEEE 802.11b protocol). Troubleshooting When mixing IEEE, 802.11b, and IEEE 802.11g wireless devices, you must set the wireless AP into a mixed (MIXED) mode, and use this mode to be compatible with IEEE, 802.11b, and 802.11g two modes. The 2. wireless client does not receive the signal Fault phenomenon After constructing WLAN, it is found that the client can not receive the wireless AP signal. fault analysis The cause of the failure may be as follows: (1) wireless LAN AP wireless router or wireless distance is too far away, beyond the coverage of the wireless network, the wireless network card to the wireless signal is very weak, the wireless client can not be connected properly. (2) wireless AP or wireless routers are not powered or do not work properly, resulting in wireless clients simply unable to connect. (3) when the wireless client is far distance wireless AP, we often use directional antenna technology to enhance the propagation of wireless signal, if the directional antenna angle problems will lead to a wireless client cannot normal connection. (4) if the wireless client does not set the network IP address correctly, it will not be able to communicate with the wireless AP. (5) for security reaso
