A method, comprising: a wireless network sharer client obtaining a wireless network list detected by a wireless network sharer terminal where the wireless network sharer client is installed; the wireless network sharer client obtaining a first identifier of a first wireless network and a first Medium Access Control, MAC, address of a corresponding wireless network device, and sending the first identifier and the first MAC address to a server, wherein the wireless network is selected from the wireless network list by a wireless network sharer that possesses the wireless network sharer terminal, and wherein the first identifier is a Service Set Identifier, SSID, of the first wireless network; the server generating a second identifier upon reception of the first identifier and sending the second identifier to the wireless network sharer client, wherein the second identifier is a character sequence meeting the requirements of an SSID, the wireless network sharer changing the first identifier of the wireless network into a third identifier, wherein the third identifier is the second identifier; the wireless network sharer client obtaining an updated wireless network list updated by the wireless network sharer terminal and receiving a second wireless network selected from the updated wireless network list by the wireless network sharer, wherein the second wireless network corresponds to the third identifier in the updated wireless network list; the wireless network sharer client sending the third identifier of the selected second wireless network and a second MAC address of a corresponding wireless network device to the server; the server comparing the second identifier with the third identifier, comparing the first MAC address of the wireless network device corresponding to the first identifier with the second MAC address of the wireless network device corresponding to the third identifier; and the server determining, by comparing the first MAC address and the second MAC address, that the first identifier and the third identifier are identifiers of the same wireless network device, and determining, when the second identifier and the third identifier are consistent, that the wireless network sharer has the right of control on the wireless network corresponding to the third identifier. a wireless network sharer client obtaining a wireless network list detected by a wireless network sharer terminal where the wireless network sharer client is installed; the wireless network sharer client obtaining a first identifier of a first wireless network and a first Medium Access Control, MAC, address of a corresponding wireless network device, and sending the first identifier and the first MAC address to a server, wherein the wireless network is selected from the wireless network list by a wireless network sharer that possesses the wireless network sharer terminal, and wherein the first identifier is a Service Set Identifier, SSID, of the first wireless network; the server generating a second identifier upon reception of the first identifier and sending the second identifier to the wireless network sharer client, wherein the second identifier is a character sequence meeting the requirements of an SSID, the wireless network sharer changing the first identifier of the wireless network into a third identifier, wherein the third identifier is the second identifier; the wireless network sharer client obtaining an updated wireless network list updated by the wireless network sharer terminal and receiving a second wireless network selected from the updated wireless network list by the wireless network sharer, wherein the second wireless network corresponds to the third identifier in the updated wireless network list; the wireless network sharer client sending the third identifier of the selected second wireless network and a second MAC address of a corresponding wireless network device to the server; the server comparing the second identifier with the third identifier, comparing the first MAC address of the wireless network device corresponding to the first identifier with the second MAC address of the wireless network device corresponding to the third identifier; and the server determining, by comparing the first MAC address and the second MAC address, that the first identifier and the third identifier are identifiers of the same wireless network device, and determining, when the second identifier and the third identifier are consistent, that the wireless network sharer has the right of control on the wireless network corresponding to the third identifier.
