The four wireless routers have multiple "Mouths" (1)

With the popularization of home networks and computers, many home and SOHO office users have multiple computers. Many users complain about the insufficient number of device interfaces when using wireless routers or broadband routers. In fact, there are only four Ethernet interfaces and one WAN interface on a common broadband wireless router, we can only connect to four computers. Is there any way to expand the number of connected devices?

How can we set up connections to maximize the number of interfaces when we have multiple broadband routers that want to scale down the number of connected devices? These problems have always plagued users. However, I recently discovered that we can use clever settings to allow four wireless routers to have multiple "Mouths", so that more network interfaces can be saved when connected to multiple routers. Next we will invite you to follow the author's tips and tips.

I. Four common wireless routers cannot:

Before learning about the "Mouth" method of the extended wireless router, we should first understand the shortcomings of the four common wireless routers on the market.

First, because the vro has only four RJ45 Ethernet interfaces, a wireless router can connect up to four network devices. Although the WAN interface is also a network interface, however, by default, this interface is responsible for external network access, so it cannot communicate smoothly with the other four interfaces by directly plugging in the computer.

Secondly, when we have multiple wireless routers that want to connect these routers to a level-1 connection, we can only connect them through the LAN interface, in this way, the number of available interfaces is 8-2 = 6. If the WAN interface is forcibly connected, communication between the eight common LAN interfaces will be very difficult, even if you can communicate, you need to set complex and complex static route entry information.

All the above problems are caused by the lack of wireless routers with only four common interfaces by default, so how do we connect five computers to a wireless router or connect multiple wireless routers together? In fact we can solve it by refreshing the DD-WRT and cleverly setting this "magic pen.
