10. A channel switching method for a wireless access point apparatus, the channel switching method comprising:
entering a first DFS channel while the wireless access point apparatus is activated;
detecting whether any radar signal is present in the first DFS channel;
entering a second DFS channel and detecting whether any radar signal is present in the second DFS channel in response to detecting that a first radar signal is in the first DFS channel, and setting the wireless access point apparatus to a first half-bandwidth connection configuration for performing a wireless communication connection in the first DFS channel in response to that no radar signal is detected in the first DFS channel; and
entering a non-DFS channel and setting the wireless access point apparatus to the first half-bandwidth connection configuration for performing the wireless communication connection in response to detecting that a second radar signal is in the second DFS channel, and setting the wireless access point apparatus to a second half-bandwidth connection configuration for performing the wireless communication connection in response to that no radar signal is detected in the second DFS channel.
