How is the Win7 router used as a switch?

1. As we all know, the routers we generally use now can only be used in four computers.

2, because the router's network cable interface is 5, 1 WAN interface, connect to the external network, and another 4 LAN interfaces, divided into four computers.

3, but some people say that my company's computer is not only 4? How to do it? A little bit of people will immediately think of adding a 8- or 16-port switch, love to pick up How many computers are connected to a number of computers, and the connection method is quite easy. The LAN port of a router is connected to the switch, and other interfaces of the switch can be used casually. In fact, the four LAN ports of the router are essentially a 4-port switch. The router we use is a combination of a router and a switch, but there are only four switch interfaces. All computers connected to the switch belong to a local area network, and computers can access each other.

4, some people have several routers on hand, that is, there is no switch, in order to save some money, I want to use a router instead of a switch to expand the number of computers. It is also easy, there are two options. In the first solution, the WAN interface of the rear router is connected to the LAN interface of the front router. This connection divides seven computers into two LANs, and computers on different LANs cannot access each other. A computer cannot share files or printers to all computers. Is there a way to make the computers connected to the two routers belong to the same LAN? The answer is yes. Option 2 is used.

5, Option 2: Only use the LAN port of the B router, the WAN port is not used. The four LAN ports in the router are originally a switch. However, each router has the function of automatically assigning addresses by DHCP. In order to prevent conflicts, one must be turned off. In addition, the LAN port of the router is generally 192.168.1.1 by default. Now the LAN ports of the two routers are connected together. If you do not conflict, you must change them. After setting up the B router, you can use it as a switch. The computer connected to it and the computer connected to the A router are in the same LAN and can access each other.

6, set the router as a switch, it is best not to connect to the network and then set, because IP conflict may not be able to log in to the router. Use a computer alone and connect it to the router's LAN port with a network cable. You can log in to the router to modify the LAN port IP address and turn off the DHCP service.

7, the computer network cable is connected to the router's LAN port, access to the router is the IP address of the LAN port, the router just bought is generally 192.168.1.1. If you have modified it, you can go to the CDM command prompt window and enter Ipconfig to find the default gateway. The default gateway is the IP address of the LAN port. “ IP address of the LAN port” That is, & nbsp; default gateway & rdquo;.

8. In the browser address bar, enter “default gateway address”, here I am 192.168.1.1. Some routers are now upgraded, no need to enter a username, just enter the password to log in to the router.

9. It is recommended to first disable the DHCP service of the router and then modify the IP address of the LAN port. Because the IP address of the LAN port is modified, some routers will automatically restart immediately, which is too much trouble.

10, the IP address of the LAN port only needs to change the LAN address that will not be used.

11. Note that after the DHCP service is closed, the IP address is modified, which means that your computer cannot automatically obtain an IP address when connecting to this router. You must set a fixed IP address to log in to the router. In addition, if the LAN port of the computer is set to 192.168.200.200, the IP address of the computer must be set to the range of 192.168.200.1-192.168.200.254 to log in to the router.

12, the router as a switch, and will not affect the wireless function of the router, regardless of which router's WiFi connected to the phone or notebook, is equivalent to the LAN port of the router, all wired and wireless devices They can access each other. Remember to set the router's WiFi password.
