Is it necessary to set up a LAN with a switch and a router?

Switches and road travelers are network equipment, in order to establish a local area network, these two devices must have one, and both can be used, but there is no need for this, just like eating with chopsticks and spoons The switch is mainly to connect multiple computers, and the road traveler not only has the function of the switch, but also has the function of the road game, which can complete the automatic dialing and other functions of ADSL

Your case is required for both switches and routers.

The switch has a 24-port that connects all the computers and routers.

The router can temporarily choose a broadband router to be used as a gateway to play the role of NAT translation and routing.

You can just ask for a router, there is no need to be so troublesome, you can connect all the machines, the router is very good.

Within a local area network, a switch is a connection for nodes.

Routing is used to connect different networks, such as LAN and WAN, LAN and Internet, between different subnets, between different VLANs, etc., as long as your network is not divided into VLANs and subnets or WAN is formed, no routing is required.

You have to have a router hood and a switch behind it to connect the router again.

1 is enough. Both of them are for networking. 1 will do.

Router: It is to connect computers to each other.

Switch: It is to connect the router to the broadband router (IP broadband does not use a switch).

OK.

Related informationThe LAN connects various computers, external devices and databases in a certain area to form a computer communication network, and connects with other local LANs or databases through special data lines to form a larger range of information processing systems. The LAN connects network servers, network workstations, printers and other network interconnection devices through network transmission media to realize system management files.

Sharing application software, town office equipment, sending work schedules and other communication services.

The local area hail attack network is a closed network, which can prevent information leakage and external network virus attacks to a certain extent, and has high security, but once hacker attacks and other events occur, it is very likely to lead to the paralysis of the local area network as a whole, and all the work in the network cannot be carried out, and even a large number of company secrets are leaked, which causes a heavy blow to the company's career development.

Hello everyone, I'm Daming, 60 computers The equipment required for the computer room is also the network cable, switch, router, this scale is even a small local area network, and then I will explain in detail how to network and <>

How to connect to a LAN with 60 computers

First of all, the first step should be to connect the "router" and the "optical modem" in series, the network cable required for series connection is not too long, one end is connected to the WAN port of the "optical modem", and the other end <>is connected to the LAN port of the "router".

Then log in to the background operation interface of the "router", find the "WAN port" option of the "Internet mode", the Internet mode is divided into three types, namely, "PPPoE broadband" to destroy "dynamic IP" and "static IP", usually the school of this scale of broadband is used "static IP", directly write the IP address into the WAN port of the router, <>

After setting up the router, when connecting the "router" and the "switch in series", you also use a network cable, one end is connected to the LAN port of the "router", and the other end is connected to any interface of the "switch" to complete the series

Note: If the interface of a switch is not enough, you can also connect a switch in series, and the two switches in series only need to be connected to any port with network cables, <>

Finally, after all the devices are set up and connected in series, you can connect 60 computers directly to the interface of the "switch" with network cables

Summary

This Q&A explains how to make a small-scale LAN with 60 computers, focusing on how to connect in series, which interface you must remember to connect to, and how to set up the router

The above is the content shared today, I hope it will be helpful to everyone, if you like it, don't forget to like and follow! Daming will continue to create works on "computer maintenance and application", if you have different views on such issues, you can discuss them together in the comment area, okay, let's see you next time!

You need to use the router connected under the switch as a switch with wireless function, how to set it:

1. Windows key + R, pop up the running interface, enter cmd enter.

<>3. Open the browser, enter the gateway address, and log in.

4. Enter the main interface, because modifying the LAN port IP may be restarted, so here first turn off the DHCP service of the router, of course, if you don't feel troublesome to restart, you don't need to do this step, as shown in the figure, click "DHCP server" "DHCP server settings" "Do not enable" "Save".

<>6. After the DHCP service is closed and the IP address is modified, it means that the computer cannot automatically obtain the IP address when connected to the router, and a fixed IP address must be set to log in to the router. In addition, if the LAN port of the computer is set, the IP address of the computer must be set to this range before you can log in to the router.

7. Using the router as a switch will not affect the wireless function of the router and can still be used normally.
