Combining two Internet Connections - Combining Bandwidth, or and Load Balancing of two Internet connections.

It is not a secret (and not necessarily a bad thing) that most of us are possessed with Speed. The fastest Car, the fastest Video for game, the fastest hard Drive, and now the fastest Internet download.

With the availability of many Internet connections a lot of people might have two broadband connections available, or Broadband + Dialup connection, or other combinations. One of the first thing that comes into their mind is: Can I combine the two connections and get a faster Download of flies and media?

First let clarify that we are talking about two independent connections. Some people try to put two modems on one DSL line, or two modems on one Cable Internet account.

It does not work this way. If by a mere “fluke” some thing is wrong with the ISP authentication system and it does work, it is illegal to do so and the ISP will caught you very fast.

So you have two independent legal Broadband accounts (can be two DSL two Cable or one of each.)

There are two terms that might be associated with using two independent Internet connections.

1. Combining Bandwidth.

2. Load Balancing two connections.

Let assume that you have two 3Mb/sec. connections each capable to download at 300KB/sec.

With Combined Bandwidth you should be able to download one file at 600KB/sec.

With Load Balancing one single file will not exceed download speed of 300KB/sec. However you can download 2 files at 300KB/sec. or 4 files at 150KB/sec. etc.

Unfortunately Combining Bandwidth can not be done without the ISP providing such a specific service.

Computers are Not mind readers. If the two connections are not synchronized at the source your computer would know how to combine it to a coherent page.

Any if and but about it is just Wishful thinking.

The price of such a service (if available) is usually much more expensive than upgrading your connection from the basic service to a faster business or corporate service.

If you do have two independent services you can achieve Load Balancing by using a Dual WAN Router.

Example: Dual WAN Router.

This type of Cable/DSL Routers have two WAN connections for two Broadband Modems and they would mange the Internet traffic to the LAN to be used in the most efficient way.
