Can two router LANs be connected to LAN interfaces?

OK. 1. The first router is set up.

It's already set, no need to worry about it!

2. Then connect one end of a network cable to the LAN port of the first router, and the other end to the LAN port of the second router.

Note: The LAN port, that is, the one that is directly connected to the computer, is often four.

How to connect two routers simply: [1] LAN port connection.

3. Find another network cable, connect one end to any one of the other three LAN ports of the second router, and connect the other end to the computer!

4. At this time, you don't need to set up a second router, you can go directly to the Internet! Try it yourself!

5. Principle analysis:

In fact, the LAN port connection method is equivalent to using the second router as a switch! So there's no need to set it up!

6. Analysis of advantages and disadvantages:

Pro: You don't need to set up a second router, you can use it directly! At the same time, the computer connected to the first router is in the same local area network and the speed is at the same level;

Disadvantages: The WAN port of the second router is invalid, and a LAN port is wasted at the same time, that is to say: the second router can only connect to 3 computers!

Khan, you're trying to use two routes.

Expand the signal, I use three routes, because there are more good routes to buy in the wall of the house, and there are some places where the signal is not available, first of all, I tell you that the routing connection itself is wrong. How can the router be connected to the LAN port? Khan, first of all, the two routes can not be the same, the first one is like this, the second must change the number after 168, otherwise there will be a connection to the first route can access the Internet, the second one cannot, or neither.

Because of the IP conflict, the DHCP automatic assignment has a conflict, and the IP address of the WAN port that you enter the router for the second time or anything can not be the same after 168. Then the first route is connected to the cat, set PPOE login, and then the first route LAN port 1234 out of the line connects to the WAN port of the second route, do not connect first, first connect the second route LAN to the computer and set the second route to log in to automatically obtain IP or static IP can also be set. Then, save the second half of the first router, the line out of the LAN port, and plug it into the WAN port of the second router.

You should be able to set up the rest, I use three routes.

Generally, there is a port to be a WAN mobile port, and a port is generally a mobile port, and only one of the two LAN ports should be a mobile port, and one is a Pudong Shijitong LAN interface.

Wireless routers.

There are two ports, generally one port is a WAN port and the other is a LAN port.

1. Functionally:

The WAN port on the router is used to connect to the Internet.

public network), or the device that connects to a broadband operator.

For example, when the Internet is connected, the WAN port is used to connect to the Moden (cat); When the optical brazing is connected to the Internet, the WAN port is used to connect to the optical modem.

When the network cable enters the home to access the Internet, the WAN port is used to connect to the home network cable.

If you want to connect to other switches or desktop computers, you can connect the network cable or not, that is, you will do the router as a wireless router, not anything else.

2. In terms of function:

WAN ports are mainly used to connect to external networks, such as ADSL, DDN, and Ethernet.

and other access lines;

The LAN port is used to connect to the home internal network, mainly with switches and hubs in the home network.

or PC connection. It can be said that these two types of network ports are one external, and the other is internal;

Downlink routing settings:

1.For example, the IP address of the LAN port of the downlink route must be different from the IP address of the LAN port of the uplink route, and the IP address of the LAN port of the downlink route must be 2

The connection type of the WAN port of the downlink router must be set to a fixed IP address, and the IP address must be in the same network segment as the IP address of the LAN port of the uplink route.

For example, the IP address of the LAN port of the uplink route and the IP address of the WAN port of the downlink route is 3For example, the subnet mask of the LAN port of the downlink route must be the same as that of the uplink route: the subnet mask of the uplink route is set to the subnet mask of the downlink route, and the subnet mask of the downlink route is set to.

4.The downlink routing gateway must not be the same as the uplink routing gateway.

For example, the uplink routing gateway is the gateway and the downlink routing gateway is the gateway.

5.For example, the downlink DNS server must be set as the uplink routing gateway, and the IP address of the downlink DNS server is the same.

The first A router IP is that your computer automatically obtains the IP address, at this time, you can see the local IP, default gateway, and DNS resolution address in the details of the local connection attribute of the computer, and write them down.

The WAN connection network cable of router B (connect to the LAN port of router A), LAN connection to your computer, open the browser and enter the login router settings interface, set the WAN port to a static IP, and fill in the data written down above.

Then set up the LAN and wireless connection (if it's a wireless router) and save the settings.

The WAN connection network cable of router B (connect to the LAN port of router A), LAN connection to your computer, open the browser and enter the login router settings interface, set the WAN port to dynamic IP, and save the settings.

After the WAN port of the router is set to automatically obtain the IP address, the network connection status of the WAN port shows "Connected", but the Internet cannot be accessed.

If the computer has automatically obtained the IP address, but the IP address is obtained, please disable the local connection or wireless connection corresponding to the computer before enabling it.

The Internet access control function of the router can restrict the Internet access permission of the intranet computer, please set this function according to the actual needs, and do not enable this function if it is not necessary.

Some wireless routers only have one WAN port.

It is the access entrance. Connect to the network cable of the broadband modem or fiber modem.

LAN port more than is connected out, connect more than one from the router to the wired end, that is, the trouble of the desktop to adopt, thank you!

Two LAN ports can be plugged into two network cables at the same time, allowing two computers to access the Internet at the same time

OK. Wireless router to wireless router, the second router is set up, there are two ways (provided that the first router has been set up):

The first method: dynamic IP mode (the first route is the primary route, and the second route is the slave route).

1. Plug in the router and do not connect the LAN port of the main router first, and reset the slave router (restore the factory);

2. Connect the computer to either LAN from the router

to enter the settings page;

3. Follow dynamic i

p mode setting;

4. Then set the SSID, encryption method and password;

5. Save and restart;

6. After setting, put the main route to LAN

The network cable that comes out of the port is connected to the WAN port from the router.

The second method: wireless AP mode.

1. Connect the computer to the LAN port of the router first, and change the IP address of the slave router. For example, most router addresses are, we just need to change from router IP address to that;

2. Turn off the DHCP function from the router in the settings;

3. Finally, connect the network cable from the main router to the LAN port of the slave router (any one is fine), note that it cannot be the WAN port.

For LAN interface, disable the DHCP function and change the gateway, otherwise there will be a conflict. Then the wireless can be used normally, and you can change the password name or something.
