Wireless network transmission slows down how to solve

Wireless LAN is more and more users of the network mode, also known as WLAN (Wirelesslan), installation is very convenient, do not need to rewiring, will not destroy the original decoration, compared to wired network, wireless network to be more flexible.

I. Specific issues

In the use of the process, sometimes we will find that its signal is not very stable, data transmission speed has slowed down, it is basically difficult to achieve 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 with this situation?

Second, the problem analysis

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.

Third, slow speed solution

Wireless router and network card matching is to enhance the speed of wireless data transmission is an important factor, we know that the current market on the wireless transmission standard has 802.11G, g+, N, B and other standards, such as we use the router is the 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.

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.

In the software aspect, the reasonable setting also facilitates provides the data transmission speed which does not have the line. 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.

The above is for the wireless router data transmission speed problem solving method, I believe that after debugging, we will solve the wireless router in the daily use of data transmission speed of the problem.
