5 GHz AP signals are divided into three frequency bands: low frequency (5150 MHz to 5250
MHz), intermediate frequency (5250 MHz to 5350 MHz), and high frequency (5725 MHz to
5825 MHz). China supports low and intermediate frequency bands, but the Radio Association
of China authorizes the 5.8 GHz frequency. Therefore, in China, the 5 GHz AP works on
radio channels that use the 5.8 GHz frequency. These optional channels include channels 149,
153, 157, 161, and 165. Many types of NICs in the market support the 5.2 GHz frequency but
not the 5.8 GHz frequency. To connect your NIC to 5 GHz AP signals, you can change the
AP's working channels to the channels in low and intermediate frequency bands.
