Problems solved by technology

[0005] After a lot of practical tests, it is found that the roaming process in this environment is actually driven by the wireless terminal device rather than the AP. The roaming algorithms of different wireless terminal devices are different, and the algorithm of each terminal manufacturer cannot be known. Therefore, Different wireless terminal devices have quite different thresholds for AP signal strength and quality, and even different models of devices from the same manufacturer have different thresholds, which makes it impossible to uniformly configure AP thresholds to achieve roaming
The common method is mostly realized by connecting to AC (wireless) controller, but the common AC controller is expensive and complicated to operate, which is not suitable for ordinary users

Abstract

The invention discloses an AP configuration method for achieving roaming in a WiFi network. When wireless APs access the network, MAC addresses of the wireless APs are uploaded to a server to be authenticated, then the APs become trusted APs, and all the trusted APs are configured to have a unified SSID, a unified encryption mode and a unified connection password. The AP configuration method is characterized by comprising the steps that WANs of all the trusted APs are configured to have a fixed IP, LANs of the trusted APs adopt DHCPs, and the IP occupied by the WANs is excluded from the start-stop range of the DHCPs; and IP addresses of the WANs of the trusted APs are different, and the address ranges of the DHCPs are different. Unified planning and configuration are conducted through the server, the WANs, the LANs, sub network masks and the address ranges of the APs are configured on the basis of the unified SSID and connection password, the switching time can be effectively shortened when AP switching is conducted, therefore, the network outage time is shortened, and the user experience is improved.
