The WiFi starting with
cu is the WiFi signal network emitted by China Unicom's router, that is, the router equipment related to China Unicom; the WiFi password of the router starting with cu needs to be checked on the sticker on the back of each device. It is a customized model of router, so the initial default password is mostly "one machine, one code".
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
The WiFi starting with CU is generally considered to be the WiFi signal emitted by China Unicom's router or smart optical modem, that is to say, it is the WiFi signal transmitted by the router or smart optical modem of China Unicom. China Unicom related router equipment.
For the initial WiFi password of a router starting with CU, you need to check the sticker on the back of each device. Since it is a customized model of router, most of the initial default passwords are "one machine, one code". The default WiFi name and WiFi password of each router are different.
Router (Router) is a device that connects various LANs and WANs in the Internet. It will automatically select and set routes according to the channel conditions, and use the best path. Send signals sequentially. Routers have been widely used in all walks of life, and products of various grades have become the main force in realizing internal connections of various backbone networks, interconnection between backbone networks, and interconnection between backbone networks and the Internet.

A router can also be called a gateway device. The router is the network layer relay and third layer relay tasks completed in OSI/RM. It stores and forwards data packets between different networks. Its main purpose is to separate the networks in different logics. Data transmitted from one subnet to another can be processed through the routing function of the router. In network communications, routers have the function of determining network addresses and selecting IP paths. They can build flexible link systems in multiple network environments and link various subnets through different data grouping and media access methods. During operation, the router only accepts information transferred from the source station or other related routers. It is an interconnection device based on the network layer.
Routers are usually located at the network layer, so routing technology is also a technology related to the network layer. Compared with early bridges, routers have many changes and differences. Generally speaking, the limitations of a network bridge are relatively large. It can only connect networks with the same or similar data link layers, and cannot connect networks with large differences in data link layers. But the router is different. It breaks this limitation and can connect any two different networks. However, one principle must be followed between these two different networks, which is to use the same network layer protocol so that they can be connected by the router. Routing technology is simply a technology that forwards and exchanges numerous information on the network. Specifically, it transmits information from the source address to the destination address through the Internet. Routing technology has also achieved good development and progress in recent years, especially the emergence of fifth-generation routers, which meet people's comprehensive applications of data, voice and images, and are gradually selected and widely used by most home networks. In addition, in the past few years, my country's routing technology has become more and more mature, and it has also been combined with contemporary intelligent technology, allowing people to experience fast and rapid effects in the process of using routing technology, thus promoting and promoting The development of the Internet and network technology.
