Background
When the existing router is in network connection with a switch or terminal equipment through a main interface, if a network is disconnected or fails, an interface switch of the router needs to be manually operated to start a second interface, and network connection is established through the second interface when the network connection of the main interface is lost, so that the failure transfer method of the router is inefficient. In addition, if the network is disconnected or fails, the router sends a ping packet to a specific IP address (e.g., DNS server) to check the network connection status.

And the third notification information is an IP address obtained after the preset website is analyzed.
In step S504, the main interface 11 completes initialization.
Step S505, the router 1 establishes a network connection with the terminal device 3 through the auxiliary interface 12.
Referring to fig. 6, a flowchart of a specific method for the router 1 to establish a network connection with the terminal device 3 through the auxiliary interface 12 is shown, which specifically includes the following steps.
Step S601, determining whether the auxiliary interface 12 of the router 1 initializes the network connection.

In the present embodiment, the auxiliary interface 12 is in communication connection with the terminal device 3 through the target communication protocol, so that the router 1 is in communication connection with the terminal device 3 through the auxiliary interface 12. However, in order to consider the communication cost, the router 1 in the present application preferentially considers the communication connection with the terminal device 3 through the host interface 11. After the router 1 performs network connection with the terminal device 3 through the auxiliary interface 12, the router 1 determines whether the main interface 11 completes initialization of network connection or performs network connection with the terminal device 3; if the main interface 11 completes initialization of network connection or performs network connection with the terminal device 3, the router 1 is in network connection with the terminal device 3 through the main interface 11.

In this embodiment, the performing, by the auxiliary interface 12, modulation initialization includes: communication parameters for the auxiliary interface 12 to communicate are initialized.
Step S704, determining whether the auxiliary interface 12 receives the modem command sent by the terminal device 3. If the auxiliary interface 12 receives the modem command sent by the terminal device 3, step S705 is executed, otherwise, if the auxiliary interface 12 does not receive the modem command sent by the terminal device 3, step S701 is executed. In this embodiment, the modem command is an Attention command.
In step S705, the auxiliary interface 12 completes initialization.
