A Wi-Fi communication method, applied to a communication system comprising a first device and a second device, wherein the first device communicates with the second device by using at least two configurable channel links, and the method comprises: sending, by the first device, link indication information to the second device, wherein the link indication information is used to indicate link attributes of the at least two channel links; receiving, by the first device, a first configuration indication fed back by the second device in response to the link indication information; and configuring, by the first device, transmission modes of non-control frames on the at least two channel links based on the first configuration indication, wherein the transmission modes comprise any one of the following: an uplink transmission mode, a downlink transmission mode, or an uplink/downlink transmission mode; wherein the at least two channel links further comprise a third channel link, and the method further comprises: receiving, by the first device, a second configuration indication sent by the second device when determining that a channel link is faulty, wherein the second configuration indication is used to indicate to replace the faulty channel link with the third channel link, and the third channel link is a channel link that is not faulty; and setting, by the first device based on the second configuration indication, a transmission mode of a non-control frame on the third channel link to be consistent with a transmission mode of a non-control frame on the faulty channel link. sending, by the first device, link indication information to the second device, wherein the link indication information is used to indicate link attributes of the at least two channel links; receiving, by the first device, a first configuration indication fed back by the second device in response to the link indication information; and configuring, by the first device, transmission modes of non-control frames on the at least two channel links based on the first configuration indication, wherein the transmission modes comprise any one of the following: an uplink transmission mode, a downlink transmission mode, or an uplink/downlink transmission mode; wherein the at least two channel links further comprise a third channel link, and the method further comprises: receiving, by the first device, a second configuration indication sent by the second device when determining that a channel link is faulty, wherein the second configuration indication is used to indicate to replace the faulty channel link with the third channel link, and the third channel link is a channel link that is not faulty; and setting, by the first device based on the second configuration indication, a transmission mode of a non-control frame on the third channel link to be consistent with a transmission mode of a non-control frame on the faulty channel link. receiving, by the first device, a second configuration indication sent by the second device when determining that a channel link is faulty, wherein the second configuration indication is used to indicate to replace the faulty channel link with the third channel link, and the third channel link is a channel link that is not faulty; and setting, by the first device based on the second configuration indication, a transmission mode of a non-control frame on the third channel link to be consistent with a transmission mode of a non-control frame on the faulty channel link.
