    D-Link Wirless Home DSL/Cable Router

    The principal of a router is simple. Since there is only one IP given to an account, the router is connected directly to the broadband connection and then it internally splits the IP's into internal IP's (as opposed to the one external IP you get) and each of the internal IP's are given to a computer on the network. As you can see, all the PC's connected to the router share the same ISP provided IP but they have different internal IP's so the router can differentiate them from one another and make sure that signals go to the right place. The only reason why there are different internal IP's is that so the router can keep track of which computers are using the Internet and what signals are going to which computers. This works both ways. When sending something to the ISP, the computer, lets say PC1 (internal IP sends an email, the data will go to the router and then the router will send it with the external IP (206.12.656.20) and when someone replies, the data will go to eh external IP and then to the router and the router knows which computer the data will go to because of the internal IP. So to sum it up in a clamshell, routers basically route the data from the ISP to the counters and vice versa. Go figure. Looking at the diagram above, you can basically tell that the router can split the connection between wireless and wired computers. It's true; the wireless receivers also get their own internal IP thanks to the built-in Access Point in the DI-711. Basically, this device is a standard D-Link router with a D-Link Access Point, if you bought this stuff separately, be prepared to spend $100 more. It's a good idea that D-Link decided to merge the 2 products together.

    Why Do You Need A Router?

    Most people who own routers like it for one main reason… it saves them money. How? First off, most ISP's that provide DSL/Cable Internet Access only gives you 1-2 IP's included in your service plan. You have to pay $5-25 more if you want more IP's. This is really a downside of broadband but an acceptable practice since most ISP lose money per IP because of the maintenance charges if they didn't charge for them. If you don't have a router and have 4 computers in the house, you might be paying $25 more a month for 2-3 extra IP's. If you do have a router bought for $200, you will save money by not having to pay for the extra IP's and also have added features such as a firewall.
