Three solutions to 802.11n wireless network FAQs

The use of wireless networks is becoming more and more popular. We are also using a variety of network problems. We have summarized wireless network problems, three methods are provided to solve common problems.

802.11n wireless networks are famous for their high speed. However, do you feel disappointed with such publicity? Many factors may affect the performance of the wireless N device. Let's take a look at it now.

The descriptions in promotional materials on the market are generally the most ideal data transmission. There are often deviations in actual situations. For example, in the promotion, the transmission rate of the wireless N network is set to 300 Mbps, but the actual use may only be 100 Mbps. You need to use other test programs to obtain the real value. Before solving the network speed problem, we must consider that the 802.11n standard is not a perfect version, and its products need to be improved.

1. Make sure you are using the new adapter.

If the maximum data transmission rate of the wireless network you see is 54Mbps or lower, you should first check whether the wireless N adapter or the old wireless G network card is used. The old adapter can connect to the new N device, but the network performance and speed will be greatly reduced. Therefore, update the wireless network device.

2. Verify that the hardware is from the same manufacturer

The reason why the Wi-Fi Alliance needs to authenticate wireless networking products is to ensure that all vendors develop devices simultaneously. However, some features are proprietary to individual vendors and must be used together. In addition, wireless N devices may involve more interoperability issues. One reason is that the official standards need to be improved is that suppliers are also launching trial products. You should use devices connected to the same vendor to avoid possible problems.

If you have not selected a preferred brand, try your own special wireless device. For example, if you want to use a wireless media extender to send photos, videos, and music to a TV from a computer, you may need to select devices of different brands. Therefore, you can find the product that suits you. After selecting a brand, you should also search for related comments online to make a trade-off.

3. Use WPA2 encryption only

The wireless N standard does not support WEP, so the connection speed with this type of encryption is limited to 54 Mbps, even with N standard devices. In addition, the first WPA version cannot even provide maximum wireless performance on N networks. Therefore, you should use WPA2 encryption technology for individuals or enterprises.

If your adapter is an old product that only supports WEP encryption, check the vendor's webpage for driver updates to ensure that the Window is up to date. If this does not help, you can change to a new wireless network card.

Enter the IP address in the browser, log on to the routing configuration tool, and change the encryption settings. The default IP address and password should be listed in the document. Find the Wireless Settings and change the encryption type.
