Intel 802.11n Wireless network card connection 802.11n No line by not achieving expected performance

Failure phenomenon:

Intel 802.11n Wireless network card, theoretical connection speed of 300Mbps, however, the actual use of the process, often only dozens of M connection speed, the highest not more than 144Mbps, as shown in the following figure:

Solution:

If you encounter this problem, you can set it below and the connection speed can be increased to nearly 300Mbps.

1. Set the wireless router to use channel binding (40MHZ). By implementing channel binding on a wireless router, routers can use 2 channels at the same time (the default is 20MHz). Channel bindings are also referred to as blending modes.

2. The following adapter settings can be found under the Advanced menu of intel® ProSet/wireless software. Your settings should be consistent with the following values. These default settings apply to intel® wireless adapters that support 802.11n.

3. On the wireless router, check the following options:

Note: WEP and Wpa-tkip are incompatible with 802.11n

Note: After you configure WEP or TKIP encryption, the data transfer rate will not exceed the Mbps.

Operating system: Windows Vista *, Windows 7 *, Windows XP *

Two. Experiment Demo

1. Tool Preparation:

A. LENOVO v490u notebook computer, WIN7 64-bit operating system;

B. Intel 2230 wireless network card, driver version 15.1.0.18;

C. d-link 615L 300M Wireless router.

2. The following figure, the default configuration, the band only one band, 20MHz, connection speed of only 72Mbps.

3. After we set up the above operation method, the connection speed is close to 300Mbps, as shown in the following figure:
