Method, device and system for accessing wireless network

A terminal device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to execute the instructions to:
• access a target router according to first access information, so as to access a part of one or more servers;
• send device verification information to the part of one or more servers;
• and
• receive second access information sent by the target router, wherein the second access information comprises an identification and a password of a wireless network for supporting accessing all of the one or more servers, and the second access information is sent by the target router according to an instruction sent from the part of one or more servers when the device verification information passes a verification performed by the part of one or more servers, the instruction being sent from the part of one or more servers to the target router for indicating to the target router that the device verification information passes the verification;
• and
• access the target router according to the second access information, so as to access all of the one or more servers.

A system for accessing a wireless network, comprising:

• a terminal device;
• a router;
• and
• a server, wherein,
• the terminal device includes a processor and a memory for storing instructions executable by the processor, the processor being configured to execute the instructions to:
• access the router according to first access information, so as to access the server as a part of one or more servers;
• send device verification information to the part of the server;
• receive second access information sent by the router, wherein the second access information comprises an identification and a password of a wireless network for supporting accessing all of the one or more servers;
• and
• access the router according to the second access information, so as to access all of the one or more servers;
• the router is configured to:
• establish a first connection with the terminal device according to the first access information;
• receive the device verification information sent by the terminal device;
• send the device verification information to the server;
• send the second access information to the terminal device according to an instruction for indicating to the router that the device verification information passes a verification;
• and
• establish a second connection with the terminal device according to the second access information after the device verification information passes a verification performed by the server;
• and
• the server is configured to:
• receive the device verification information sent by the terminal device via the router;
• perform the verification on the terminal device according to the device verification information;
• and
• send the instruction for indicating to the router that the device verification information passes the verification to the router.
