Frequency band switching method and terminal

A frequency band switching terminal supporting WiFi communication on at least two frequency bands, the terminal comprising:

• at least one processor;
• and
• a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
• in response to determining that information is transmitted with a first access point (AP) by using a first frequency band, detect a value of a channel quality parameter group of the first frequency band, wherein the channel quality parameter group of the first frequency band comprises at least one channel quality parameter, the at least one channel quality parameter indicating a channel quality of the first frequency band,
• in response to determining that the value of the channel quality parameter group of the first frequency band detected by the terminal meets a preset condition, send a connection request to a second AP while the terminal is connected with the first AP by using the first frequency band, wherein the connection request comprises a request for establishing a connection with the second AP by using a second frequency band, and
• in response to determining that a success message fed back by the second AP according to the connection request is received, establish the connection with the second AP by using the second frequency band, and then send a disconnection instruction to the first AP, wherein the disconnection instruction is used to break a connection with the first AP.
