Five computers, two routers, how to form a local area network

Go buy a 6-port switch, you can connect all 5 computers together to form a LAN without a router, the IP address is set to the same as the gateway, for example, the IP address is set to:, x Each machine must be different, and the gateway is set to, it must be the same, and then connect the router and the switch when you want to connect to the external network, in fact, the 8-port switch is the most common, and the price of 6 ports is dozens of dollars.

If you're on a laptop, you can set up a Wi-Fi network for online play! Set up a wireless network with a wireless card. It also omits the line of routing.

Vista and Win 7 go to Network & Sharing Center - Set Up Connection or Network - Set Up Wireless Temporary Network. Fill in the network name at will, such as Warcraft. If there are five computers using XP, it will not be encrypted, but it can be encrypted with Vista and Win 7.

Just one of the computers can be set up, and the other computers can open the wireless network card and search for it. The firewall will pop up when you play Warcraft, remember to allow access to the network! All LAN games can be played over this network.

xp to go to the online neighbor settings. The same is to create a new network.

It's very easy to turn into a VLAN.

The question is simple.

A is set up as you do.

When the total number of computers does not exceed 6, the WAN port of B is idle, the LAN of A is directly used on the LAN of B, and the DHCP of B is turned off, and the LAN is also set to achievement.

Principle: B is used as a switch, and the computer under B is also automatically assigned an IP address by DHCP of route A. In this way, the computers under A and B are in the same network segment, and a local area network can be formed, and any two computers can visit each other.

Option 1 (Home router).

Route 1 wan pppoe

Route 1 LAN

Route 2 WAN port is not plugged in (not applicable).

Route 2 LAN is not configured.

Route 2 disables the DHCP service.

Scenario 2 (Professional Routing).

Route 1 wan pppoe

Route 1 LAN

Route 2 WAN

Route 2 LAN Configure Default Route IP Route Next Hop Route 2 with any private address other than the CIDR block Configure Default Route IP Route

Yes, you have to turn off the DHCP function of one of them, for example: you have two routers, A and B, A is used as an access B for switches, then you need to turn off the DHCP function of B, and set the LAN port address of B to be different from the address of A, assuming that the LAN port address of A is the default, then you had better set B to this way, and it will definitely not go wrong. But when you want to manage the router, you need to manually change the NIC address) or this address will not be assigned to the client to reduce the possibility of conflicts). Then plug the network cable from the LAN port of Router A into the LAN port of Router B, and connect the PC to the LAN port of Router B.

Here's how it works:

1. First of all, set the LAN port IP of the two routers to be different, such as the setting of A and the setting of B.

2. A and B dormitories of several computers, open the network and sharing center, IPv4 protocol, manually specify the IP address (, X is the number of 3 255, do not repeat), the gateway points to and respectively.

3. Connect the LAN port of the two routers with a network cable, then A and B will build a LAN, and after passing the corresponding LAN settings, they can be shared, and each computer will still access the Internet through the router of its own dormitory, without affecting each other.

The b-router should be set to bridge mode directly, and the second one is like this.

Two routers with advanced connection skills to form the same LAN for easy management and network sharing.

They've all been very detailed, and I'll just answer the last question, as you said.
