Wireless LAN, also known as WLAN (Wireless LAN), has become more and more users use the network formation.Wireless Network Setup is very easy, no need to re-wiring.So do not destroy the furnishings of the family, compared with wired networks, wireless networks to be much more flexible.
In use, we found that although there is no emission lines WLAN trouble, and very easy to use, but sometimes we will find the signal is not stable, slow data transmission speed of the phenomenon is basically related to the wireless router is difficult to achieveThe nominal speed.Such a nominal is 54Mbps (the actual transfer rate at 20Mbps or so) of the WLAN network, but the display speed is only 11Mbps (the actual transfer rate at about 4Mbps), 5.5Mbps (the actual transfer rate at about 2Mbps) or less, the mostto this situation, how should we deal with it?
First, we briefly about data transmission speed of wireless network causes slow, radio waves in the air, it spreads easily by a variety of obstacles, the source of interference to the interference, which naturally will cause slow transmission speed WLAN.In addition, wireless transmission distance is limited, despite the general wireless router nominal transmission distance can reach 100 to 300 meters, but in actual use in the barrier if so, this distance will be dramatically reduced and will result in slower data transmission.
Know the reasons for slow speeds we can purposefully to address this problem.First time we have to grasp the layout is good, wireless routers and computers equipped with wireless cards can communicate between the best as far as possible to avoid blocking wall between them, especially the load-bearing walls (reinforced concrete wall).We know that, in order to reduce the radiation on the human body, the wireless router's power are generally not large, so in the course of Hen capacity Shoudao electronic interference of equipment around, so set the display location of a wireless router, we must remember Yuan Limicrowave ovens, refrigerators and other appliances.
The antenna is a good wireless router to ensure the effective transmission distance and stability to ensure that some high-end wireless router will use two antennas, antenna products in general more than one antenna in the transmission performance of products more secure, if possible, weSelect pairs of antennas as a wireless router or more antennas.Also the size of the antenna gain influence on the data transmission is also very important, common router generally comes standard with an antenna gain of 2dBi omnidirectional antenna, but many high-performance wireless router with really 3dBi or 5dBi omni-directional antenna.There is no doubt that the same environment, with 5dBi omni antenna performance of wireless router will certainly be better than 2-3dBi omnidirectional antenna products.Therefore, we can use high-gain antenna to improve wireless signal status.
Wireless router and network card is to enhance the matching between the wireless data transfer speed is an important factor, we know the market of wireless transmission standard has 802.11G, G +, N, B and other standards, such as a router we use is adopted108Mbps's 802.11G + standard, but using a wireless network card 11Mbps (802.11b) standard, so its certainly not reach the actual speed of 108Mbps, then we need to upgrade the network card in order to achieve the best result.In the purchase of related products, we must choose the same standard wireless router and network card, so as to minimize compatibility problems.
In front of us is the hardware for the main transmission speed of wireless routing, the software, the setting is also conducive to a reasonable offer wireless data transfer speed routing.We know that most wireless routers support WEP or WPA encryption, though effective use of encryption to enhance the confidentiality of the family network performance, but more or less affect the data transmission speed, for the average home wireless networks,, WEP or WPA encryption of very limited, so we can turn off or disable this feature.In addition, sometimes we can connect to the Internet via wireless router to upgrade the drive to improve the performance of wireless transmission.
Believe that, after the above debug, we will solve the wireless router appears in the daily use of the data transmission speed is dropping.
