What does a broadband wireless router mean? What is a broadband router

Let's briefly talk about the principle of broadband Internet access. Broadband Internet access is via ** line. So there is the router:

Its function is to modulate and demodulate the network signal to a frequency that can be used by the computer, which is equivalent to converting LAN to WAN (this is the relationship between LAN and WAN). Then the computer will be able to access the Internet. Then there is the wireless network, the router just mentioned above, which transmits information through network cables.

Then the wireless network is to change the network cable transmission method into a wireless transmission mode. As for the direct Internet access in the KFC, it is because there is already a wireless network through the wireless router (like there is already a network cable). You can use it when you connect it) ps:

An average wireless router can usually make about 30 computers wireless at the same time. The wireless router inside the KFC is definitely more upscale. Hehe.

I'll come: 1, KFC can access the Internet inside, because the notebook you use, now a better notebook, all come with a wireless network card, so you can directly access the Internet. 2. If you want both machines to access the Internet, if you don't connect, you must ensure that both of your machines have wireless network cards, and you need to buy a wireless router connected to your ADSL's cat, and the wireless signal sent by the wireless router can only be accessed after being accepted by your machine.

If you have a wireless network card, you can search for wireless networks when you go to KFC, and then enter it to access the Internet. As for what you said about using two machines to surf the Internet at the same time, you have to use something similar to a router, which can also be a switch, a hub, or something like that. Then connect your broadband interface to the router, and then connect two twisted pair cables from the router to connect your two machines to access the Internet, if it is ADSL Internet access, you need to set it up and password in the router.

To access the Internet wirelessly, you need to have a wireless network card and a wireless router together. Wireless network card and wireless network card are two different concepts, wireless network card and mobile phone Internet access, to have traffic, slow speed. Buy a router for your two computers and share the Internet.

The wireless router is to send a signal, and the wireless network card is used to receive!! WAN external network port, LAN internal network.

Analysis: What is a broadband router.

As you know, a router is a device that connects the network of the unit and the network of other units or the Internet, and the broadband router is a device that supports a variety of broadband access methods and allows multiple users or local area networks to share the same to achieve broadband access.

After 2000, not only home computers and commercial computers began to enter a large number of home and office user groups, ADSL, VDSL, CM, FTTX+lan and other broadband access methods have also sprung up in China.

The emergence of broadband routers has provided convenience for solving the increasing broadband application needs of broadband users with low investment, which generally has 1 or even 2-4 WAN interfaces, can automatically detect or manually set the access type of broadband operators, can connect to ADSL, VDSL, CM, FTTX+LAN and other broadband access, has the function of embedding PPPOE virtual dialing or DHCP client, and can assign a fixed public IP address.

When you have a broadband router, all computers in the LAN no longer need to install any client software, nor do you need to set any ** server address to easily share broadband Internet access. In addition, it generally comes with 2-4 port switches, which can easily realize the access of small LANs, and the broadband routers with strong performance can share the Internet with about 100-200 machines.

Hello Pro Wireless router is a router that is used for users to surf the Internet with wireless coverage function. A wireless router can be seen as a device that sends broadband network signals from the wall of your home to nearby wireless network devices (laptops, Wi-Fi-enabled mobile phones, tablets, and all Wi-Fi enabled devices) through antennas.

What does wireless router mean? Wireless router", literally, everyone may think that it is a router with increased wireless capabilities. However, people in the industry generally call this kind of home unlimited router "wireless AP", not a router (router).

In fact, in addition to itself, wireless AP is also a general term for wireless routers (including wireless gateways and wireless bridges). First of all, let's talk about what wireless AP is, the full name of wireless AP is unlimited access point (access point), which is an extension of wired network. To put it simply, it's a few antennas on the router.

In the use of large enterprises, schools, and hotels, wireless APs (thin) are generally used to implement Wi-Fi coverage, and then connect to PoE switches. And they come in a variety of shapes, which is not the common appearance of wireless routers nowadays. The wireless router is a wireless AP with router part function, which is connected to the ADSL broadband line, realizes automatic dial-up access to the network through the function of the router, and establishes an independent wireless home LAN network through the wireless function.

It means that there is an optical fiber interface on a router, which is generally a WAN port, which is the port that is plugged into a telecom line.

There are also four Ethernets.

port (connected to RJ45 crystal head),Now the number of router interface megabytes is generally 1000 megabytes,It doesn't matter much,Anyway, broadband can't use such a high speed。 If the broadband used is not optical fiber access, you don't need to buy such a router, and an ordinary four-network cable port router will do.

The precautions for the installation and use of optical jumping fiber are as follows:

1. Optical fiber jumper.

Li at both ends of the optical module.

The wavelength of transmitting and receiving must be consistent, that is to say, both ends of the optical fiber must be optical modules of the same wavelength, and the simple way to distinguish them is to have the same color of optical modules. In general, short-wave optical modules use multi-mode optical fibers (orange optical fibers), and long-wave optical modules use single-mode optical fibers.

yellow optical fiber) to ensure the accuracy of data transmission.

2. Before use, the ceramic ferrule and ferrule end face of the optical fiber jumper must be wiped clean with alcohol and absorbent cotton.

3. When the optical fiber is installed, it is easy to cause the optical fiber ferrule to deviate due to excessive force, which affects the quality of optical communication.

4. Do not bend and wrap the optical fiber excessively in use, which will increase the attenuation of light in the transmission process.

5. After the optical fiber jumper is used, it must be used with a protective sleeve to spoil the fiber joint.

Protect it, which can balance dust and oil can damage the coupling of the fiber.

6. Do not look directly at the end face of the optical fiber when the laser signal is transmitted.

A router, also known as a gateway device, is used to connect multiple logically separated networks, and the so-called logical network represents a single network or a subnet. When data is transferred from one subnet to another, it can be done through the router's routing function.

Therefore, the router has the function of judging the network address and selecting the IP path, it can establish a flexible connection in the multi-network interconnection environment, can connect various subnets with completely different data packets and media access methods, the router only accepts the information of the origin server or other routers, and belongs to a kind of interconnection device at the network layer.

A wireless router is a router with wireless coverage function, which is mainly used for user Internet access and wireless coverage. Popular wireless routers on the market generally support four access modes: dedicated line XDSL cable, dynamic XDSL, and PPTP, and it also has some other network management functions, such as DHCP service, NAT firewall, MAC address filtering, and so on.
