A channel scanning device ( 100 ) for scanning channel status of a wireless local area network (WLAN) is provided. The channel scanning device includes a status recording module ( 120 ), a transmission module ( 130 ), and a probing module ( 140 ). The status recording module is used for setting up a channel status list including multiple sequence fields and status fields, the sequence fields representing a channel sequence, and one sequence field together with a status field corresponding to each channel. The probing module is used for pre-probing the channel according to the channel sequence, in order to find an idle channel, probing the idle channel, and recording the channel status into the channel status list set up by the status recording module. The transmission module is used for transmitting a pre-probe packet over the idle channel. A channel scanning method for scanning channel status of the WLAN is also disclosed.
