How to use a router to set up a LAN?

A router is not needed for a local area network.

Routers are used to connect multiple subnets.

How to set up a LAN with a router: Follow the following method to set up.

Home Network Environment Cabling]:

1. There is a cat (modem): cat (modem) - router WAN port; The LAN port of the router --- a computer.

2. No modem: network cable --- router WAN port; The LAN port of the router --- a computer.

[Computer enters the router]:

1. The computer IP and DNS settings are automatically obtained.

2. Open the browser, enter the general router address in the address bar is this or check the login information on the back of the router) Enter the route - enter the user name and password, (the default is generally admin).

Set Router Dialing]:

1. In the [Setup Wizard], select [PPPoe Dialing] (some are ADSL Dialing), enter the Internet user name and password according to the prompts, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

A router is a device that connects various LANs and WANs on the Internet, and it will automatically select and set routes according to the situation of the channel, and send signals in the order of the best path. A router is the hub of the Internet"Traffic police"。At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet.

The main difference between routing and switching is that the switch takes place at the second layer of the OSI reference model (data link layer), while the routing takes place at the third layer, which is the network layer. This difference determines that routers and switches need to use different control information in the process of moving information, so the way they achieve their respective functions is different.

A router, also known as a gateway, 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.

Divide less. But for the sake of such a pertinent question, I'll tell you, maybe it can help you.

First, get your router and switch ready. I won't say much about the function of routing and the function of the switch.

Then, connect the network cable (inlet) to the route, and connect a network cable to the computer in a single connection. The purpose of this is to facilitate debugging. Connect the route to the switch. Since you have 40 computers, you decide how many switches to choose.

Then, set up the router. Use a computer connected directly to the router to go to the router settings, the usual settings are the username and password are admin on the special router manual.

After entering Set the IP Range. Assign IP Address to specify the Internet access permissions for certain IP segments. For example, within the computer to access the Internet. You can also bind according to the MAC and go to the specific routing settings to view.

As for the speed limit, I haven't seen it set in the route until now, and maybe I don't see it much. I usually use a server to do speed limiting. Maybe some high-end routers have it.

To be honest, this question doesn't need to be scored!

2. Form a LAN with 40 computers. And assign an IP address to each computer 3, bind each IP's to MAC to prevent a computer from being poisoned and affecting other computers 4, segmented speed limiting, to prevent someone from using BT, Thunderbolt and the like.

2. Just draw a private address segment (

3 and 4 do it in the router management interface (see the model router above and what functions are supported, "read the manual").

I've seen this kind of router.,In the router, you can set the IP binding to the MAC,IP address speed limit,You go to the computer city to ask or call the network service provider service **Ask if there is such a router.。

First of all, you need to have a professional router and a switch.

On the router, you can do MAC binding, traffic control, etc.

Buy a good router, depending on your requirements, buy an enterprise-class one. For specific operations, please refer to the actual router manual and graphical interface.

5 points Seriously, I'm too lazy to answer.

Let's go up first** and give a perceptual understanding. Below the router is a LAN computer.

The WAN port of the TP-Link router must also be connected to the cat.

The general TP-Link wireless router configuration is as follows (if it is a wired router, please ignore the steps of wireless setup):

0) If it is ADSL access, prepare two network cables, one network cable to connect the computer network port to the LAN port of the router, and the other to connect the LAN port of the cat to the WAN port of the router (the computer network cable is connected to the router in order to configure the router, if you use wireless, after configuration, you can unplug it).

1) The router is powered on, and the cat is powered on.

2) Find the router's manual.

3) Find the management IP of the router (generally, login account password (such as admin admin), login ** example -->

4) Statically set the IP address of the computer host and the management IP in the same network segment (if the router is enabled by DHCP function by default, then set the computer network card to automatically obtain the IP).

5) Log in to the wireless router management interface.

6) Turn on the DCHP service of the wireless router.

7) The wireless router is set up with PPPoe auto-dialing function to connect permanently.

8) Turn on the wireless function of the wireless router and set the wireless Internet password (if it is a wireless router, the password setting is complicated).

This should be able to automatically dial up the Internet, wired and wireless at the same time.

PS: If the router is enabled DHCP by default, then the IP and DNS of the computer should be set to automatically obtain, so that if multiple computers form a LAN, there is no need to set the IP.

If you have any questions, please contact us.

Good luck, hehe.

A local area network can be formed.

1.Turn on the power of the router, plug the two network cables into the network card of the computer, and plug the other end into the LAN port of the router.

2.Change the network cards of both computers to automatically obtain IP addresses, because TP-Link routers provide DHCP by default to dynamically assign IP addresses.

3.After all the above is set up, it forms a LAN of 2 computers, which is simple. Open CS, two people can PK.

If you still want to connect to the Internet, sell another network cable to connect to the WAN port of the router, and connect the Internet modem to the other end. Set up PPPoe dial-up Internet access in the router, you can realize broadband sharing and time sharing (that is, 2 computers go online, only charge the money of one computer), and it is affordable.

Mine, hope it helps.

How to build a LAN with a router:

The devices connected to the LAN port of the router are all in a local area network.

If you don't use a cat, then where do you connect the wire, there is no interface for the cable on the router.

You put the cat out of the line on the WAN port, connect the computer to the line LAN port and then set the IP in your own computer, the gateway is set, and then enter the routing settings in the browser, if you can't get in, the third bit of the computer's IP is set to 0, the gateway is also changed to 0, and then enter the routing settings in the browser, the account password is admin, according to the setup wizard step by step, the Internet mode is set to ppp0e other defaults, enter the Internet account and password given to you by telecommunications, After that, take a look at the status to see if it is connected, and finally both computers are set to automatically get the IP, and that's it!! If you don't set up your own IP, you need to add DNS

The router has 1 WAN external network access entrance The others are the branch port 2 and the network cable are plugged into the branch port of the router Connect to the computer and the desktop open the router respectively Set the IP on any computer The other is the next time it starts, which machine starts first, that is, the host.

You can also open IE on any computer and enter it in the address bar to enter the router settings, and the default password is admin

If you want to connect to the Internet, connect the network cable that came out of the cat to the wan, and you can access the Internet according to the wizard settings in the router.

This is simple, the router is connected to the desktop, the notebook, respectively, with a good network cable, the IP of both computers is set to automatically obtain, or one is set to, one is set to, the subnet mask is all, the gateway is all, and then you can access each other.

I have 3 computers. Two 3rd floors and one 2nd floor, I'm also worried about how to secure the line.

I have 3 computers. Nothing for the rest! How do you get a column?
