How is the Win7 router used as a switch?

1, as we all know, we now commonly used routers in general can only be divided into four computers to use.

2, because the router's network cable interface on 5, 1 WAN interface, the external network, the other 4 LAN interface, divided into four PCs.

3, but some people say, my company's computer more than 4 units ah? What about it? People who know a little bit of it immediately think, add a 8 or 16-port switch, how many computers will be connected to the number of computers, the way to connect is quite easy, make up a router LAN port and switch phase, Other interfaces on the switch can be used casually. In fact, the router's 4 LAN port is essentially a 4-port switch, the router we use is a combination of routers and switches, but only 4 exchange interfaces. All computers connected to a switch belong to a local area network, and computers can access each other.

4, some people have a number of routers on hand, there is no switch, in order to save money, want to use a router to replace the switch, the expansion of computer numbers. That's easy, there are two kinds of options. Scenario one, the WAN interface of the rear router is connected to the LAN interface of the former router. This method divides 7 computers into two LANs, and computers with different LANs do not have access to each other. A computer can't share a file or printer with all the computers. Is there a way to have two routers connected to a local area network? The answer is yes. You want to use scenario two.

5, Scheme two: use only the LAN port of B router, Wan mouth not. The 4 LAN ports in the router are inherently a switch. However, each router has the ability to automatically assign addresses to DHCP, and one must be turned off in order to prevent conflicts. In addition, the router's LAN port is generally the default is 192.168.1.1, now two routers are connected to the LAN port, to do not conflict, must be changed. After setting up the B router, you can use it as a switch, and the computer connected to a router is in a local area network and can access each other.

6, the router is set up as a switch, it is best not to connect to the network before setting up, because the IP conflict may lead to log on the router. By using a single computer, connecting the network cable to the router's LAN port, you can log on to the router to modify the LAN port IP address and turn off the DHCP service.

7, the computer network cable connected to the router's LAN port, access to the router is the LAN port IP address, just bought the router is generally 192.168.1.1. If modified, you can go to the CDM Command Prompt window, enter ipconfig to find "default gateway", "Default gateway" is "IP address of LAN port", "IP address of LAN port" is "Default gateway".

8, in the browser address bar, enter the "Default gateway address", I here is 192.168.1.1. Now some of the routers are upgraded, do not need to enter the user name, only need to enter the password can log on to the router.

9, it is recommended to first turn off the router's DHCP service, and then modify the LAN port IP address. Because the IP address of LAN port is modified, some routers will automatically restart immediately, too troublesome.

10, LAN port IP address only need to change will not be used in the LAN address on the line.

11. Note that after the DHCP service is shut down, the IP address is changed, which means that your computer cannot get the IP address automatically, so you can set up a fixed IP address to log on 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 192.168.200.1-192.168.200.254 this range in order to log on to the router.

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