Does a data TV extension have to be a router?

Multi-port (several ports can be on several computers, there are four, eight, sixteen, etc.) routers (about dozens of yuan), set your router according to the following data, you can realize the sharing of the Internet: if you use the router to build a local area network, the network sharing equipment; In general: Here's how to connect and set up:

Connect the network cable (RJ-45) of your broadband modem to the WAN of the router, and connect the network cable (RJ-45) to the LAN port of the router for the rest of the computer. 2: The IP address of the computer network card is set to be automatically obtained, and there is also input in the address bar of the computer browser, specifically according to the network parameters obtained by your computer network card, through the IP address of the gateway to log in to the router, most of the usernames and passwords are admin, select WAN port settings. 3：

Set your broadband account and password to the PPPoE mode (if it is a fixed IP address, you should select the static IP mode). 4: After saving, restart the computer and it's OK.

Thank you for my answer!

Thank you: friend! …

It is best to use a special distributor for cable TV, also called "one point two", which can ensure that the signal quality of the two lines is the same. About 20 yuan a piece.

First of all, use the router to access the Internet regardless of the host and extension As long as the route can access the Internet, your host can access the Internet You should be able to understand this schematic diagram **Line--adsl cat--router--- Host 1 -- Host 2 -- Host 3 -- Host 4 The network cable of the general home router can be plugged into the back of 4 computer hosts Dial-up Internet access through the router, and then the host does not need to dial up, and the network cable can be plugged into the router directlyYou need to set the IP address of the computer host to be obtained automatically (if you know the IP address range of the router, you can also set it manually, but it is recommended to get it automatically)2Open the webpage -- enter the webpage in the address bar to automatically jump into the entrance of the routing setting interface Username:

admin password: admin (the username and password here, I just assume that the router of tp-link, if it is different, you can turn the router over, generally the back of the router is recorded) 3Click OK, enter the router page settings, you directly click on the WLAN settings, there is a PPPOE in it, select him, and then enter the username and password (this username and password, is your broadband account and broadband password) After setting, there should be an option at the bottom:

Automatic connection, connect when needed, manual connection, if you are a monthly user, it is recommended to connect automatically, as long as the connection is dropped, the router will automatically connect, if it is a package, it is recommended to connect manually, so as to avoid the waste of time when not in use, if it is a manual connection, you need to enter the router after each time you open the route. You can follow step 2 After the setup is completed, the point is saved Generally there is no need to route from the beginning If it is an automatic connection, when you save, the router will automatically connect, and after the dial-up is successful, you can go online, if it is a manual connection, you need to connect by yourself, and after the connection is successful, you can access the Internet Finally, if you use the router to dial-up to connect to the Internet, your host does not need to dial up separately, because the router represents your host and makes a dial-up connection, and your host is used as an extension. Network sharing through the router, in layman's terms, is like this Then all your hosts just plug the network cable into the network interface behind the router, set the IP address, and you can access the Internet All your hosts are just an intranet of the router General page router settings, similar to this, I hope these will help you

How to set it up:

1. The host is connected to the LAN port of this router, and after logging in, first modify its LAN port address, which is not the same network segment as the parent router, for example, the upper LAN port is, then the lower level can be set to, and the router will restart after modification;

3. After restarting, log in to the router with a new address, set its Internet access mode to dynamic IP, then turn on the wireless function, set the encryption method and password;

4. Finally, connect the WAN port of this router with the LAN port of the superior router with a network cable.

1. To set the interface type of the WAN port, whether the router at the upper level automatically assigns the IP address, or manually assigns the IP, it should be set in the WAN port setting interface according to different types;

3. Your router should turn on the DHCP function and automatically assign IP addresses to the Internet devices connected to the router;

4. Your Internet access device is set to automatically obtain an IP address.

You try it.

If someone else assigns you a network cable to connect to the WAN port, and the computer is connected to the LAN port, your router must be set to a dynamic IP. It should be noted that the IP address of the LAN port of the router cannot be the same as the gateway you used to access the Internet before (if the previous one is, your router should be changed to; The DHCP server of the router is turned on.

What brand of router is yours.

Use a switch instead of a router to share the Internet, any computer in the LAN can be the host dial-up Internet first, and other machines can also access the Internet, and the method of surfing the Internet for friends is adsl.

The specific connection method is as follows:

ADSL Internet access, connect the modem to the switch (or the broadband network cable of Telecom directly to the switch), the host IP setting method used to dial up the Internet first: see the local connection in the network connection, click the right health selection properties, click the Internet Protocol (ICP IP) attribute in front of the icon displayed in the notification area after the connection, and click to use the following IP address: IP address to fill in:

Subnet Mask:, Default Gateway:, Preferred DNS Server:

Point OK. Then establish an ADSL connection on this machine, and then click on the ADSL connection to select the attribute Advanced: will allow other network users to connect through the Internet connection of this computer.

Other machines also use the local connection attribute of the right health point in the network connection to automatically obtain the address.

In this way, the first to establish a connection enters the account password to connect to the Internet, and after dialing in to connect, the other machines will naturally connect.

Other machines can also be the host, and other machines can be the host to establish the same dial-up account and password, (in fact, there is no need to set up each one like this, and use one or two machines used by managers to set it up like this, just say that this method can work, and these connected computers are set up with a solid IP in the LAN, which is also easy to manage).

This method only uses a switch instead of a router to share the Internet, does not use a server, and only needs a network card on the host used for dial-up, and there is no need to add another network card or anything, which is simple and convenient.

I'm using a switch to share the internet.

o( o haha

The router is used as a switch: the WAN port of the router is not used, and the other four ports are connected to the cat and the computer.

For home use, the network cable from the optical modem is connected to the WAN port of the main router, and the LAN port of the main router is connected to the WAN port of the extension router, and all WAN ports can be directly connected to the computer. The CIDR blocks of the primary router and the extension router cannot be the same.

The IP address of the WAN port of the secondary router must be the same as the IP address of the LAN port of the primary router, and the LAN port address of the secondary router should be different from the network segment of the primary router.

2. Connect the computer from any LAN port of the router to enter the settings page

3. Set according to the dynamic IP;

4. Then set the SSID, encryption method and password

5. Save and restart;

6. After setting, connect the network cable from the LAN port of the main router to the WAN port from the router.

The second method: wireless AP mode.

1. Connect the computer to the LAN port of the router first, and change the IP address of the slave router. For example, most router addresses are, and we just need to change the IP address from the router to that

2. In the settings, turn off the DHCP function from the router;

3. Finally, connect the network cable from the main router to the LAN port of the slave router (any one is fine), note that it cannot be the WAN port.

What a route, poisoned and then can't get on the network. It doesn't have much to do with routing!

The key is that the DNS code must be correct.

After connecting the router, enter the lower-level router, click on the automatic selection connection, or bridge it.

No, the advantage of mesh is that it is decentralized, so that each route can be used as the main route to connect to other mesh nodes, and each node can also connect to each other without connecting to the main route to achieve network access.

Wireless mesh networks are a new type of wireless local area network. Unlike traditional WLANs, APs in a wireless mesh network can be wirelessly interconnected, and multi-hop wireless links can be established between APs.

Mesh is composed of a set of wireless APs distributed in a mesh pattern, all of which are interconnected through wireless relay links in a point-to-point manner, extending the wireless "hot spots" in traditional WLANs to wireless "hot spots" with truly large-area coverage.

Self-configuring: APs in a wireless mesh network have the capabilities of automatic configuration and centralized management, simplifying network management and maintenance.

Self-healing, APs in a wireless mesh network are equipped with automatic discovery and dynamic routing connections to eliminate the impact of a single point of failure on services and provide redundant paths.

The first and second floors are right, using a router to access the Internet, there will be no host, extension, to ensure that there is no problem with the hardware and connection, that is, the network is set up. It's mostly a connectivity issue. You try to make it work first.

The computer transmits a digital signal and should use a repeater.

8. In this way, the cable network of the desktop machine can be used. Set the IP attribute of the wireless network card of the notebook to be obtained automatically, and refresh the wireless network (you need to swipe it several times at the beginning), click Settings after finding it, enter the password (the password set above), and save.

Dear, if you think my answer is helpful to you, please give a thumbs up! If you have any other questions in the future, you can click on my avatar to consult me, and I will give you the most satisfactory answer.

You ping the DNS server to see if there is any packet loss and how about the latency.

The distance looks a bit far.

To be more specific, from moderm to router to extension, how are they connected?

Route settings (IP, NDS, etc.).

Network cable (test the cable).

Are all IP DNS gateway addresses set correctly? Turn on the cloning function of the router's NIC.

See if the fitting is good?

Try to connect the network cable at the near end of the router to see if there is a network cable, and if there is a network cable problem of 200m. Please be patient with the troubleshooting!
