Why are cats and routers separate?

Router and cat must be used at the same time.

1.

Routers and cats don't have to be used at the same time. This needs to be based on the currently purchased network.

It is the analysis of telephone dial-up network, residential wired access network and optical fiber network;

2.

Now routers and cats have been generally integrated together, and optical fiber networks have integrated equipment, optical fiber cats.

Have the function of router and cat;

3.

Telephone line ADSL can choose two devices, cat and router, or integrated device dial-up Internet access.

The network cable of the community is connected to the network. Generally, as long as the router sets the account and password, it can automatically dial up the Internet.

Routers and cats can't be put together?

Routers and cats can be put together. Now there are also products that combine cats with routers. For example, 2 lines.

Usually, the reason for not putting the two together is heat and mutual interference. In fact, this will not affect each other.

When the cat and the router are put together, the biggest impact is that both will generate heat, and the heat generated by the router and the cat is not very large. As long as the cooling holes are not stacked together.

The twisted pair connected between two devices is shielded. The important chips of the two devices, such as the wireless routing main chip, also have the function of heat dissipation or shielding. If you are afraid of interference, you can also put a layer of tin foil between the two devices.

Can't cats and wireless routers be put together?

The router doesn't have to be with the cat.

1, the effective transmission distance of the network cable led by the optical cat or ADSL cat can reach about 100 meters, so the distance that the router can leave the cat is 100 meters.

2. The broadband of the community metropolitan area network is directly connected to the home through the network cable. This method does not need cat conversion, and the network cable is directly connected to the WAN port of the router.

3. There is also brouter mode, where the slave router is connected to the main route through wireless, and the slave route can be far away.

It could have been installed separately. The optical cat is connected to the input optical fiber, and then the output network cable is connected to the route. However, the output network cable can only be connected to one router, and then the routers need to be linked to each other.

Can the wireless router be separated from the cat?

The wireless router can be separated from the cat,

1, when setting up the router, the computer needs to connect the network cable. After setting it up, you can separate it, because the router has nothing to do with the computer when dialing, and you can still use wired and wireless normally.

2. Wireless router settings.

1, select PPPoE dial-up (some are ADSL dial-up) in the setup wizard, enter the user name and password for surfing the Internet according to the prompt steps, and save.

2. In the network parameters-WAN settings, select normal mode, and in the three options of connection, select PPPoE dialing. The following are the options for automatically connecting, saving and quitting.

3. After setting, you can separate from the cat.

Are broadband cats and routers the same thing?

Cats and routers have different functions and cannot be used instead of each other. Now some manufacturers make a router and a cat into a device, which is convenient for users to use.

First, the working principle of cats and routers

Generally speaking, cats are also called broadband cats, which are abbreviated as Modem in English and modem in Chinese. Its function is to connect your computer with network operators (such as China Unicom and Great Wall Broadband), identify and decode data streams by frequency, and connect your computer with the Internet after receiving the data.

The "routing" of a router refers to the behavior and action of transmitting data from one place to another. A router is a machine that performs this behavior and action. Its English name is Router.

2. What is the fundamental difference between a router and a cat?

Routers are used to distribute connections and realize simultaneous connection of multiple computers to form a local area network; Broadband cat is a kind of equipment used for dial-up internet access, which mainly converts the network model into audio signals and then transmits them through telephone lines.

The basic functions of a router are as follows:

1. Network interconnection: Routers support various LAN and WAN interfaces, which are mainly used for interconnection of LAN and WAN to realize communication between different networks;

2. Data processing: providing functions including packet filtering, packet forwarding, priority, multiplexing, encryption, compression, firewall, etc.

Third, network management: routers provide functions including router configuration management, performance management, fault-tolerant management, traffic control and so on.

Cat (actually called modem) is a device that converts analog signals into digital signals. No matter what kind of cat it is, it plugs a cable into this device, and then a network cable comes out of this device and plugs it into your computer, so that your computer can dial up the Internet.

Third, how to choose a router and a cat?

If you only need a computer at home and have no plans to buy one for the time being, you don't need to buy a router. You only need a cat, and the operator may give you one when you apply for broadband service.

If there are many computers at home, which are stationary, you need to buy a wired router, which is generally good (around 70 yuan). If there are several computers at home, including laptops and smart phones with wifi, it is recommended to buy a wireless router (home 100 yuan or so). The difference between wired and wireless is that wireless is convenient, but the speed is not as stable as wired; Wired is fast, but not as fast as wireless.
