What is the difference between a router and a cat?
The difference between routers and cats: 1. Cats communicate with the Internet service provider's network, while routers share network connections to multiple devices; 2. Cats have a relatively single appearance, while routers come in various shapes Diverse; 3. The cat is a necessary device for computer networking, and the router is a device that helps multiple computers share a network; 4. One end of the cat is connected to the telephone line, one end is connected to the computer or router, and one end of the router is connected to the cat , the other end can only be connected to a computer; 5. The modem has only two ports, one is connected to the telephone line and the other is connected to the network cable, while the router has more ports.
Routers and modems are two common network devices that play different roles in the network. Although they have some overlapping functionality, their primary functions and working principles are different. This article will explain in detail the difference between routers and cats.
A router is a network device used to connect multiple computers or other network devices and enable them to communicate with each other. It connects multiple devices through different interfaces (such as Ethernet, Wi-Fi, etc.) and transmits data packets from one network to another according to the internal routing table. Simply put, routers are responsible for sending data from sender to receiver and ensuring the correct transmission of data across the network.
1. Definitions of Different
A modem communicates with your internet service provider's network, while a router is basically used to share a network connection to multiple devices.
2. Different shapes
The appearance of a cat is relatively simple, like a flat rectangular box, which is very small. However, the shape of routers is diverse, including rectangular and rectangular. Oval in shape, the overall volume is larger than that of a cat, and the wireless router also has a different number of antenna devices.
3. Different functions
A cat is a necessary device for computer networking. Only with a cat can a computer be able to dial-up the Internet, and a router is a device that helps multiple computers share a network. With the help of a router, several computers can access the Internet on the same network cable. However, a router is not a necessary device for computers to access the Internet. Without a router, computers can still access the Internet through a modem.
4. Different connection methods
Due to their different functions, the connection methods of the two are also different. One end of the cat is connected to the telephone line, one end is connected to the computer or router, and one end of the router is connected Cat, the other end can only be connected to the computer. Directly connecting the phone line and the computer using the router cannot achieve networking.
5. Different ports
The port shapes and numbers of the two are different. The cat's port generally only has two, one is connected to the telephone line and the other is connected to the network cable, while the router's port is relatively There are usually five, one is connected to the cat, and the rest can be connected to one or more computers at will.

Can. However, you need to pay attention to some issues: 1. Placing the router upside down may have a certain impact on heat dissipation, causing heat to accumulate at the bottom of the router, affecting the heat dissipation effect. Long-term overheating may reduce the performance of the router and adversely affect its lifespan. ; 2. Placing the router upside down may affect the operation and management of the device, and the indicator lights and interfaces may be blocked or inconvenient to operate; 3. Placing the router upside down may also have a certain impact on network security, and the default user name and password may cause This information is more susceptible to prying eyes.

The impact of turning off dhcp on the router: 1. The client cannot automatically obtain an IP address; 2. The IP address needs to be configured manually; 3. It may cause network connection problems; 4. It affects the communication of network devices; 5. IP address conflicts; 6. Unable to proceed Dynamic address allocation; 7. Network isolation cannot be performed; 8. Traffic control cannot be performed; 9. Access control cannot be performed. It is recommended that before turning off the DHCP service, carefully consider whether it really needs to be turned off, or keep the DHCP service to ensure that the client can automatically obtain the correct IP address.

The first light is on, indicating that the router is powered on. Which port is plugged in, the light of which port is on, and flashing means data is being transmitted. Wireless routers usually have three indicator lights: SYS, LAN and WAN. When the wireless router is powered on, the SYS light will light up. When the wireless router is connected to the network modem, the WAN light will light up. The LAN light corresponds to each interface of the wireless router. As long as the network cable is inserted into the corresponding interface, the corresponding LAN light will light up. 1. If it keeps flashing, it means it is transmitted by data, and the router settings should be normal. 2. If you have always been able to access the Internet, but you can't get online recently; it is probably a problem with the external line, that is, a problem with the operator (usually there is a problem with the line, causing the data signal to attenuate too much, although the line is good)

Students who know computers all know that if our computer wants to connect to the network, it must have an IP address. This IP address can be manually configured, such as 172.16.19.20; it can also be automatically obtained by the DHCP server of the computer network card, such as 192.168.1.100 etc. These IP addresses are what we often call IPV4 addresses, and the corresponding IPV6 is also a type of IP address. What is IPV6 IPV6 is a new IP address that emerged in response to the exhaustion of IPV4 address resources. Its full name is "Internet Protocol Version 6", and its Chinese name is the sixth generation of Internet Protocol. The number of IPv6 addresses is theoretically 2^128

How to connect the optical modem to the wireless router: 1. Connect the LAN port of the optical modem to the WLAN port of the router; 2. Use a toothpick or needle to poke the reset button of the router; 3. There is usually a management page on the back of the router, such as The one on the router is tplolgin.cn. Enter this address in the browser. If it does not exist, enter 192.168.1.1. This is the default address of the router. 4. Enter the management page. You will first be asked to set the administrator password. Set it up. You can enter the router settings and so on.

Placing the router upside down may have some effects on the network, including reduced signal coverage, blocked signal transmission, poor temperature and heat dissipation, and reduced network speed. Detailed introduction: 1. The signal coverage is reduced. Routers are usually designed to radiate signals outward in a horizontal direction. Therefore, placing the router upside down may cause the signal coverage to be reduced, which may cause signal in some areas. Weakening, thus affecting the stability and speed of the connection; 2. Signal transmission is blocked. Placing the router upside down may cause signal transmission to be blocked, etc.

The flashing pon light on the optical modem means that the optical modem is trying to establish a network connection. The PON light is a registration indicator light used to indicate whether the optical modem has successfully registered and established a connection. When the PON light flashes, it means that the optical modem is trying to establish a connection. This is usually because the line or equipment is faulty, causing the optical modem to be unable to establish a connection with the gateway. You need to check whether the indoor line connection is correct and whether there is any bending angle that is too large. wiring, and whether there are any loose connectors. If the line connection is normal, you can try to restart the optical modem and gateway to restore the network connection.
