Perfect solution for dual-route internet access [Original]_ Networking Tutorials

A few days ago a friend asked me to help him set up. From the routed LAN port to the next line, and he's going to use the route to another 3 computers, I used to directly from the first route connected to the second routing of the WAN, how can not surf the internet, know to tell Ah,
My solution:
The first routing connection is connected to a second routed LAN port, and if the first route IP is 192.168.1.1, the IP for the second route is set to 192.168.1.99, and the IP address of the local network card is 192.168.1.100. Note that it is best to turn off the DHCP function of the router so that the network speed can be faster.
Disadvantages: Only three computers
Other ways to find from the Internet, you can refer to the following
The following routers are used as switches.
To set up:
192.168.1.1, enter the router Setup interface:
A total of three options: 1,pppoe,
2, dynamic IP
3, Static IP
Choose 2 or 3, simply set it to use.
This gateway is not the same as your modem's gateway ...
If the same will not be able to surf the Internet, routers can change the gateway, to see for themselves ...
