As shown in the following illustration:

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.
