Abstract: A matching method for network access apparatus is provided. The matching method is used for performing a register confirmation between a first network access apparatus and a second network access apparatus and obtaining an IP address through a remote server for sharing data. The method comprises the following steps. The second network access apparatus stores an ID code of the first network access apparatus transmitted directly by the first network access apparatus. The first and the second network access apparatuses connect with the remote server, respectively. The second network access apparatus obtains the IP address of the first network access apparatus from the remote server according to the ID code of the first network access apparatus.

Abstract: An automatic backup setting method on wireless network is provided. A linking request is transmitted by at least one electronic device. An ID code of the at least one electronic device is obtained and stored by the network access apparatus according to a network transfer protocol in response to the linking request. The at least one electronic device is informed by the network access apparatus to transmit a data identification information once the network access apparatus confirms that the link with the at least one electronic device is established. The data identification information is compared with a backup data list stored in the network access apparatus by the network access apparatus. If the data identification information is not in the backup data list, the at least one electronic device is informed by the network access apparatus to transmit the data.
