802.11n Wireless network card Performance Introduction

Do you know the 802.11n wireless network card? Do you know how to use a 802.11n wireless card to achieve higher performance? Don't worry, let's take a minute to explain. Quickly through the following understand it, will certainly let you have a different understanding of 802.11n wireless card.

The descriptions in the marketing literature are usually the most ideal data transfer. The real situation is often biased. For example, the propagation rate of a wireless N network is advertised as 300Mbps, although it may only be 100Mbps in real use. You need to use other test programs to get the real value. In solving the speed problem before, the first thing to consider is: 802.11n wireless network card standard is not a perfect version, its products are still to be perfected.

1, to confirm that you are using the new adapter using the 802.11N wireless network card, if you see the maximum data transfer rate of 54Mbps or lower, the first to see whether the use of wireless N adapter or the old Wireless G network card.

Old adapters can connect new n devices, but network performance and speed can be drastically reduced. So, to update the wireless device.

2, verify that the hardware is produced from the same manufacturers WiFi alliance to the wireless networking products to authenticate, is to ensure that manufacturers are synchronized development of equipment.

However, some features are proprietary to individual manufacturers, must be used to support the use of the line. In addition, Wireless N devices may involve more interoperability issues.

The official standards need to be perfected is one reason, the supplier is also the trial product. You should use networking equipment with the same manufacturer as the 802.11n wireless network card to avoid problems that may arise.

If you don't have a favorite brand, try a special wireless device that you once owned. For example, if you want to use a wireless media extender to send photos, videos and music from your computer to your TV, you may want to select between different brands of equipment. Therefore, the balance can be found to suit their own products. Select a brand, you should also search the Internet for relevant comments, and finally make a choice.

3, only use WPA2 encryption Wireless N standard does not support WEP, so use this kind of encryption connection speed will be limited to 54Mbps, even if the use of N standard equipment is no exception.

In addition, the first WPA version does not even provide maximum wireless performance on n Networks. Therefore, you should use WPA2 personal or enterprise encryption technology.

If your adapter is an old product that can only support WEP encryption, check the vendor's Web page for driver updates to make sure Windows is up to date. If this is not helpful, you can switch to a new wireless network card.

In the browser, enter the IP address, login routing Configuration tool, change the encryption settings. The default IP and password should be listed in the document. Locate the wireless settings and change the encryption type.

4, change the default bandwidth, access to efficient network if installed 802.11n wireless card, and complete the above changes, the speed is not more than 130Mbps, perhaps to change the default bandwidth. To reduce network interference with old WiFi devices, Wireless N Routing and Access points use 20MHz bands.

Some of the performance growth in Wireless N is due to the conversion to the 40MHz band, a technique known as channel binding technology (Channel bonding). Therefore, to achieve maximum speed, you need to change this default setting first.

Open the browser, enter the routing IP address to the Web Interface Configuration tool, enable channel binding. Locate the wireless settings and select the 40MHz band. Finally remember to save the changes.

5, disable the wireless G client to improve the performance of n-Network Wireless N Network for Wireless G network, even the B-standard network has backward compatibility. However, when the old adapter is connected to the N network, the traffic in the network is managed separately. Such compatibility has a negative impact on speed and performance. Therefore, if your speed transmission is not up to your needs, make sure that the network is only available to Wireless N clients. Log on to the Web interface's configuration tool and change the wireless settings to do this.

If you want to support wireless b/g customers, consider using a previous wireless G route or access point. Wireless g routing or access points can be connected to the back end of the new route. If you use channel bindings on n routes, you must make sure that they are all placed in a channel that does not overlap: 1,6 or 11, or 1, or 11. Then verify that only the N standard connections are used on the new route.

6, only in the case of strong signal use of 40Mhz band as mentioned above, in the use of 802.11n wireless network card, in order to allow Wireless N networks faster than 130Mbps, the frequency must be converted to 40Mhz. However, if all users have bad network signals, you may reconsider whether to enable channel binding. Because it does reduce the user's signal.

7, check the network interference and other wireless G network, you should be concerned about the common network interference problems, such as the proximity of the access point to the use of the network caused by channel interference, other radio and electronic equipment to network interference, etc.

However, there is another problem with the Wireless N network. Remember, if you switch the default channel band from 20 to 40MHz, the frequency range of the signal is doubled.

If you use channel binding, you cannot use two of the three typical channels that do not overlap. So you have to make sure that you only use Channel 1 or 11 at all access points. Check the signal to see if there are other networks nearby, and then select the channel as appropriate.
