How to access the router settings interface when there is no network (solve the problem of how to access the router settings interface when there is no network)

In daily life, we often need to manage and configure the network through the router settings interface. However, when we do not have an Internet connection, we cannot directly access the router settings interface through regular methods. How should we enter the router settings interface when there is no Internet? This article will give you details on how to solve this problem. 1. Use the default gateway IP address. Each router has a default gateway IP address, through which you can directly access the router's setting interface. You can find this address by looking in your router's manual or on the bottom of your router. Generally, the default gateway IP address is 192.168.1.1 or 192.168.0.1.

Understand ansible architecture and working principles

Ansible is a model-driven configuration manager that supports multi-node publishing and remote task execution. By default, SSH is used for remote connections.
