Wireless internet signal is one of the reasons that affect wireless speed, so for this, let's see how to solve it. Then we need to analyze from a few points: remove the external signal interference, tuning wireless node equipment and other "fragmented" trick.
Remove interference from external signals
If there are external electrical signals or magnetic signals to interfere with the normal transmission of wireless internet signals, then the efficiency of wireless Internet access will also be significantly affected, so we should be as far as possible to remove the external signal interference away. As with ordinary wireless communication, the transmission of wireless internet signal can be interfered by other electromagnetic signals. Because ieee802.11b/g wireless Internet standard working frequency of 2.4GHz, and the real life of many industrial equipment working frequency is also in this range, so wireless internet signal is very vulnerable to the same frequency of communication signals or electromagnetic signals "harassment."
If there is a very strong electric field or magnetic field near the WLAN, the transmission of wireless internet signal will inevitably be affected. For example, some friends put the wireless router device or wireless node equipment in the vicinity of such high-power household appliances, such as air-conditioning, the results found in the air-conditioning equipment is working, wireless Internet will appear strange network drop fault, and the air-conditioning equipment shut down after the wireless workstation can be normal access to wireless LAN network.
We also found that the speed of wireless internet transmission is not very stable whenever a unit employee uses a mobile phone for a wireless call near a wireless router device or wireless node device, mainly because the wireless internet signal is affected by the disturbance of the mobile communication signal. Therefore, when we find that there is a strong electric field or strong magnetic field in the local WLAN, we should remove these strong electric or strong magnetic field emission sources as soon as possible, and make sure the wireless internet signal can be transmitted in a relatively stable environment. If you encounter a special phenomenon with the same frequency, we may wish to enter the background management interface of the wireless router device or wireless node device, and adjust their working frequency in order to eliminate the effect of interference.
Tuning Wireless Node Equipment
Learn to "tune" wireless routers or wireless node devices to ensure they emit the strongest wireless signal. If after careful testing, found that wireless internet signal is very weak, but the wireless router device or wireless node devices have not recently changed location, then we might as well try to change the wireless router or wireless node equipment channel parameters, to see whether the wireless Internet signal emission intensity can be enhanced. To modify the wireless internet signal channel parameters, we only as a system administrator into the wireless router or wireless node device background management interface, find the channel parameters, and then on the original numerical basis for a slight modification.
If you are using a wireless router device or wireless node device that supports automatic dialing, we may wish to successfully enable this feature in a timely manner so that the wireless router device or wireless node device can be successfully connected to the Internet network when it is opened; In order to automatically set the appropriate TCP/IP parameters for each workstation in the WLAN, we can also enable the wireless router device or wireless node device built-in DHCP function, which can also improve the efficiency of the wireless workstation.
If the local wireless LAN use of wireless router device or wireless node device support antenna removable function, then we will encounter when the internet signal is weak phenomenon, may wish to consider the wireless router equipment or wireless node equipment to remove the original antenna, another installation of a wireless gain antenna, Used to enhance the amplification of wireless internet signal, generally speaking, the price of such equipment is often cheaper. If we have to ensure that the wireless internet signal in the transmission process does not decay, and to ensure that the signal transmission distance is far away, that can consider the use of a large gain value of the wireless antenna, on the contrary, if the transmission distance of the wireless signal is relatively near, we only use a small gain value antenna can solve the problem. Of course, for PCI wireless network card devices, considering that they need to be installed in the workstation's mainframe box, so many friends worry that the PCI wireless network card with the antenna will be blocked by the workstation chassis, thus affecting the normal reception of wireless internet signals; in fact, We can go to the market to pick the length of the feeder antenna, to improve the wireless workstation on the Internet signal reception capabilities, otherwise installed in the workstation of the PCI wireless network card and wireless node device can not establish a reliable wireless connection.
Other "odds and ends" trick
There are still a lot of tricks to improve the efficiency of wireless Internet. For example, we can use the wireless workstation in the same two model of the same wireless network card devices, their load parameters are balanced set, so that they work at the same time, so invisible to improve the wireless workstation signal reception capabilities, The speed of wireless Internet access in this way is about 1.5 times times faster than that of a single NIC.
If you have only one wireless card device on hand, we can try to improve the transmission speed of wireless internet signal from the angle of saving bandwidth resources. For example, when downloading information or browsing information, a lot of malicious programs, advertising information will be transmitted with useful information to the local hard drive, and this garbage content will undoubtedly consume a lot of valuable bandwidth resources, so we can try to use some professional tools, such as advertising information such as spam all filtered out, In order to reduce the transmission of wireless signals, so as to achieve the purpose of saving valuable bandwidth resources; For example, we can try to use the relevant advertising interceptors, or the software to eliminate rogue programs to reduce the useless network traffic, while the unnecessary picture display function temporarily closed, etc. Ensure that the limited network bandwidth resources are all used for the transmission of effective information, so that the speed of wireless internet can be significantly improved.
In addition, the Internet bandwidth resources unchanged under the premise, if we can skillfully use information compression technology to the capacity of the larger information compression processing, and then the compressed information transmission out, you can indirectly achieve the purpose of improving the efficiency of wireless signal transmission.
