How is the Win7 system router used as a switch?

A router is an external device that we are very common. With it, we can use WiFi, but some people want to use the router as a switch to save money. So what do you do? How to use the Win7 system router as a switch? Friends who don't understand, take a quick look at the following tutorials compiled by Xiaobian!

Method /Step:

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

2, because the router on the network line interface 5, a WAN interface, then the external network, LAN interface to the other four, four points with a computer.

3, but some people say, my company's computer only four ah? then what should we do? People who know a little bit will immediately think of adding a 8-port or 16-port switch. 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. The 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 routers have several staff head, that there is no switch, in order to save money, wanted to replace the switch with a router, expanding 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, Scheme II: B only router LAN port, WAN port no. 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 to switch, not the best first connected to the network and then set, because a conflict could lead to IP router can not log on. 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, computer network cable attached to the LAN port on the router, the router is accessed using the IP address of the LAN port, routers are generally bought to 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 & ldquo; & rdquo ;, the default gateway address I have here is 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, recommended to first turn off the router's DHCP service, and then change 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, IP address of the LAN port LAN requires only a change of address will not be used on the line.

11, note that the DHCP service shuts down, the IP address changes, it means that the router can not connect your computer to automatically obtain an IP address, to 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 with, and does not affect the wireless function of the router, using a mobile phone or laptop no matter which router is connected to WiFi, are the equivalent attached to the LAN port on the router, all wired It can be accessed from each other and from wireless devices. Remember to set the router's WiFi password.

These are the router how Win7 system when the switch with the tutorial, very simple, but be careful to change the router's LAN IP address.
