Dual-wan Routers

The concept of dual-WAN is an intriguing one, and has shown itself to be as promising in practice as it is in theory. The concept behind dual-WAN is that you can increase your connection speed beyond what is currently available by joining two separate internet connections together.

Many of us get used to surfing and file sharing at T-1 or faster speeds at work, and it is easy to be spoiled. When we get home and are stuck with DSL, cable, or, worst of all, dial-up, it can make the time spent at the computer unbearable. What is a minor inconvenience if you are surfing the Internet is a major problem if you are trying to do some work at home.

To form a dual-WAN connection, you join two separate broadband links. The links can be whatever you have available--broadband, fixed wireless, satellite, or another combination. The two services are linked into one seamless dual pipe. This new connection is faster, and can be shared by all the computers on your local area network. If you have more than one computer on your LAN, the benefit of increasing the connection speed will be more obvious. Multiple connections allow for the network to process each request more quickly. Even if you only have one computer on your network, the increased speed will decrease download time, and increase surfing speed.

Any two types of internet connection can be used to form a dual-WAN, as long as they both use ethernet. Many people find that the dual-WAN, with multiple connections, is an excellent backup. When they are in situations where they may lose one type of connection, such as a phone line, the other connection (for example, satellite) still works. This, along with the increased connection speed, is enough to convince many people to invest in a dual-WAN connection.
