How to use two wireless network routers to build a network

How can I use two wireless network routers in a home network to build a network? The following is a good solution to the problem of wireless routing. When I bought EeePC, I also bought a wireless network router. After I bought it, I encountered a problem: I already have a router. How can I add another router? All the information found on the internet is too professional and is of little use to amateurs like me. I repeatedly set various parameters. It took me one night to complete the installation. Below are some configuration points. I will record them and hope they will be useful to other friends.

Let's talk about the network situation in my home. I use ADSL to access the Internet. ADSL Modem connects directly to the telephone line, followed by a router. Then, I pulled two wires, one for the PC in the big room to access the Internet, the other for my room, and a switch for my desktop and notebook to access the Internet. What I want to do is replace the vswitch with a wireless network router. Of course, the simplest method is to disable the routing function of the wireless network router and turn it into a wireless switch, so that nothing can be set. However, the one I bought does not seem to have this option in the system, so I had to go through another troublesome path.

Step 1: connect two routers with a crossover line. This is critical, but it is easy to ignore. I forgot this, so I couldn't set it all. I finally remembered to use the cross line. By the way, we can record that the normal cabling sequence is "White orange, orange, white green, blue, white blue, green, white brown, brown ", the crossover sequence is "white green, green, white orange, blue, white blue, orange, white brown, brown ".

Step 2: Set the Internet IP address of the second router. Because the vro serves to connect two networks, two IP addresses are required, one being external and the other being internal. Generally, the IP address of the first router is "192.168.1.1" and the subnet mask is "255.255.255.0 ". The Internet IP address of the second router must be in the same CIDR block as the first router, that is, it must be set to an integer between 192.168.1.x and 2 and 254 ). If the Internet IP address of the second wireless network router is not set to a static address, it is set to automatic acquisition, that is, the first router is automatically allocated through the DHCP protocol.

Step 3: Set the Intranet IP address of the second vro. The Intranet IP address is for all devices under the vro. This IP address will be used for future login and modification of vro settings. My settings are "192.168.2.1" and the subnet mask is "255.255.255.0 ".

Step 4: Set all devices connected to the Internet through the second wireless network router. In fact, this step does not need to be set. Generally, the operating system automatically obtains the IP address by default. This is the best choice, and it is best not to modify it. If you must set it to a static IP address, it must be "192.168.2.x" x is an integer between 2 and 254), The Subnet Mask "255.255.255.0", the gateway "192.168.2.1", and the DNS "192.168.1.1 ".

Now, you can access the Internet normally. It seems very simple. It can be done in five minutes, but it took me four hours to figure it out.
