Tips for wireless router acceleration

Wireless LAN, also known as WLAN (Wireless LAN), has become a more and more users of the networking approach. Wireless network installation is very convenient, do not need to rewiring. So it will not destroy the original home decoration, compared to the cable network, wireless network is much more flexible.

In the use of the process, we found that although the WLAN does not have the trouble of wiring, and easy to use, but sometimes we will find its signal is not very stable, data transmission speed has slowed down, it is basically difficult to reach the relevant wireless router nominal transmission speed. such as a 54Mbps (actual transmission rate of 20Mbps or so) WLAN network, but its display transmission speed only 11Mbps (actual transmission rate of around 4Mbps), 5.5Mbps (actual transmission rate in the 2Mbps or so) or lower, What should we do to deal with this situation?

First of all, we have a simple understanding of the reasons for the slow speed of wireless network data transmission, radio waves in the air can easily be disturbed by a variety of obstacles, interference sources to interfere, which naturally causes the WLAN transmission speed slows down. In addition, wireless network transmission distance is limited, although the general wireless router nominal transmission distance can reach 100~300 meters, but in the actual use if there is a barrier, this distance will be shortened dramatically and will lead to slow data transmission speed.

Knowing the slow speed of transmission, we can begin to solve the problem with a targeted approach. First in the layout of the time we have to grasp, wireless router and equipped with wireless network card between the best to see, as far as possible to avoid the wall between them, especially the load-bearing wall (reinforced concrete wall). We know that in order to reduce the radiation on the human body, the power of the wireless router is generally small, so the use of the process is very much in the vicinity of electronic equipment interference, so in the setting of wireless router placement, we must remember to stay away from microwave ovens, refrigerators and other household appliances.

Good antenna is also to ensure that the router wireless transmission distance and stability of the effective guarantee that some high-end wireless routers will use two antennas, in general, more than a single antenna products in the transmission performance is more secure, if possible we try to choose a dual antenna or more antenna wireless router. In addition, the antenna gain size on the impact of data transmission is also very important, ordinary routers generally only standard antenna gain for the 2dBi omni antenna, but many high-performance wireless router equipped with is indeed 3dBi or 5dBi omni antenna. There is no doubt that the same environment, the use of 5dBi omni-Antenna wireless router performance is certainly better than the 2-3DBI omnidirectional antenna products. So we can improve the wireless signal condition by switching to a high gain antenna.

Wireless router and network card matching is also to enhance the speed of wireless data transmission is an important factor, we know that the current market wireless transmission standards have 802.11G, g+, N, B and other standards, such as we use the router is 108Mbps 802.11G + standard, But the wireless card uses the 11Mbps (802.11B) standard, so in its actual speed must not reach 108Mbps, then we need to upgrade the network card to achieve the best compatibility effect. In the purchase of related products, we must choose to adopt the same standard wireless router and network card, so as to minimize the occurrence of compatibility problems.

We introduced the main hardware aspects of the transmission speed without the impact of the software, the reasonable setting is also conducive to provide no line by the data transmission speed. We know that most wireless routers now support WEP or WPA encryption, although the use of encryption is effective to enhance the privacy of the home network, but it will more or less affect the speed of data transmission, for the general Home wireless network, WEP or WPA encryption does not work, So we can turn off or disable this feature. In addition, sometimes we can improve the performance of wireless transmission by upgrading the drive of the wireless router by connecting to the Internet.

Believe that through the above debugging, we will solve the wireless router in the daily use of the data transmission speed of the problem.
