3 minutes to learn the router’s cable bridge connection

First of all, explain that the second -level route situation referred to in this article is

Wired connection


, Not the wireless bridge.

In most cases, we take the second -level route to directly connect the line of the upper -level route to the WAN port of the secondary route. Names and passwords are finished, convenient and fast. However, there are certain flaws in this way. When the customer uses the main coverage area of ​​the first -level routing to the main coverage area of ​​the secondary route, if this time can still receive the signal of the first -level route, but it is relatively weak. At this time The mobile phone will not switch to the secondary routing with a stronger signal, or there is a obvious process of falling back. This is mainly because the IP network segment assigned by the first -level routing is different. For example, the first -level route is 192.168.1.x network segment, and the secondary route may be 192.168.2.x network segments. process.

Another way to say next is to allow customers to achieve seamless roaming without awareness without one router, and to switch without perception.

Take Mercury 325 as an example

First of all, the main routing is set normally, enter the interface of the main routing, click the advanced settings-network parameter-DHCP server, and check the start and end address of the address pool. This article is

In the second step, the secondary route is powered on, and the main route is not connected to the network line (if you set it with a computer, you can connect a network cable from the computer to the secondary route). Enter the sub -router settings interface, directly skip the guide, and set the wireless network name and password setting as the main route. Then the high-level settings-network parameter-DHCP server, turn off the DHCP server. Finally, in the LAN port settings, the LAN port IP is automatically changed from manual, and the IP address is set to the last one of the main routing address pool in the first step (in this way, generally there will not be IP conflicts), and then save and wait for the router to restart.

The third step is to plug in the network cable. In this step, we must pay special attention to the LAN port of the main route from the LAN entrance, not the WAN port, and then try it. It is already good. Seamless roaming between.

In fact, the principle of this setting method is relatively simple, that is, the DHCP of the deputy route is turned off, so that the secondary routing will no longer allocate the IP address to the access device. Equivalent to a wireless switch.
