I have a VDSL cat, how to surf the Internet at home Aren t people using ADSL to surf the Internet at

It's not irreplaceable, in fact, there is no difference, it's just a problem with network operators, they may block the connection of cats from some manufacturers, or they may only be open to some manufacturers, they may do this to prevent some people from stealing bandwidth resources Now Netcom companies should send cats, and it will never be wrong to send them.

ADSL must use a cat to access the Internet, and it is logged in with a username and password.

In addition, Telecom has LAN mode to access the Internet, according to them the minimum network speed is 2M, but I opened their box to see, it is nothing more than ADSL+ switch. In other words, it is to open the cat bigger, and use the switch to share the Internet with several companies, which saves trouble! Just set the IP, and the public account is automatically bracketed by the ADSL (this cat fixed belt route).

Community broadband, the outside line can be connected to the Internet (LAN).

ADSL wants the cat to dial up the Internet.

yes！

No cats, no internet!

Cat is a common name, cat is a modem, ADSL dial-up Internet access needs to use cats. It is the ADSL client device connected by the computer and the ** wire, which is a small square with four small lights on it, and the ** line is connected to the computer through it, and it is called"Cats"(Chinese pronunciation of modem).

Desktop Internet access must use cats, laptop Internet access without cats, can use wireless network Cats are used to convert Internet signals If there is wireless network around, the laptop can be connected directly to wifi.

Broadband modem is used to dial up the ADSL provided by TelecomWhat is a broadband router As you know, a router is a device that connects the network of this unit and the network or the Internet of other units, and a broadband router is a device that supports a variety of broadband access methods and allows multiple users or LAN to share the same account 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 provides 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 client function of PPPOE virtual dial-up or DHCP, 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 local area networks, and broadband routers with strong performance can share Internet access with about 100-200 machines. Broadband cat is used to provide the ADSL dialer router can be **, but can not replace the cat, if it is a pull of the optical fiber, do not use the cat, only connect the router can, the cat is a modem, analog and digital signal conversion, the router can not convert which, the router can be set to help you dial the number, connect to the Internet, can provide the router function to the computer to allow computers to access each other" But there is a "routing cat" can be simply understood as a route + cat If a computer uses** Online with cats.

One with a double bridge cable to get two computers on, using a router. But you don't need to use the hat cat now, the slow speed is scary, it is recommended to use the adsl terminal, the speed is faster.

The "cat" in broadband is actually a homonym for an English word, which is modem, a modulation modem.

If you want to surf the Internet, this thing is indispensable, and you can't see it on your laptop because it's already built-in.

A wideband moden, or moden, is a modem, which is a device that communicates between computers over a ** line.

The wideband modulation process is mainly as follows: digital signal becomes analog signal - > transmission - > analog signal becomes digital signal.

Cats have external and built-in, generally today's laptops have built-in cats, home desktop computers use external types, after the communication company buys broadband services, they will send a cat, just follow the steps on the instructions to install it.

Modem: The scientific name is modem, and its main function is to convert analog signals into digital signals or digital signals into analog signals. There are now three ways to access broadband:

ADSL, community metro network broadband, fiber exclusive broadband. There are two of these three ways to use cats: fiber broadband and ADSL broadband.

Therefore, the optical modem is just a way of broadband cats.

Optical modem, also known as single-port optical transceiver, is a three-piece optical fiber transmission equipment developed for special user environments. The device adopts a large-scale integrated chip, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.

Chinese name: modem.

Product Name: modem

Definition: A general term for a modulator and a demodulator combined. A conversion interface that enables digital data to be transmitted over analog signal transmission lines.

A modem is a kind of computer hardware, which can translate the digital signals of the computer into pulse signals that can be transmitted along the ordinary ** line, and these pulse signals can be received by another modem at the other end of the line, and translated into a language that the computer can understand. This simple process completes the communication between the two computers.

modem, in fact, is the abbreviation of modulator (modulator) and demodulator (demodulator), Chinese called modem (Hong Kong and Taiwan called modem). According to the homonym of modem, it is affectionately called "cat".

No, it is not available. ADSL is downloaded up and down at different speeds. VDSL is downloaded at the same speed up and down.

VDSL (Very-High-Bit-Rate Digital Subscriber Loop) is a fast version of ADSL. With VDSL, the maximum downlink rate over short distances can reach 55Mbps, and the upload rate can reach or even higher (different manufacturers' chipsets support different speeds. Chipsets from the same manufacturer, using different frequency bands, offer different speeds.

At present, the most used in the market is Infineon's kit, which supports 512k 15M bandwidth. In addition, Conexant's kits can support 100M and 50M bandwidths, and some Taiwanese chipsets can also support 100M and 65M bandwidths).

Method: 1. Check the login information on the back of the optical modem.

3. The router login interface pops up, and enters the default login username of the router.

How to set up: Use a super password to set up dialing.

1. Enter the modem setting interface.

2. Select Internet connection and select "Create WAN Connection" in the "Connection Name" drop-down list. You can select the LAN1 and LAN2 check boxes. In this way, both ports can be connected to the network cable to access the Internet.

3. Enter the Internet access and password in the username and password fields.

There's no way, what else can you do if Telecom doesn't install VDSL for you.

VDSL is much faster than ADSL.
