How to Compare DSL Modems

A digital subscriber line (DSL) modem allows your computer to upload and download data through an Internet service provider. Not all DSL modems are created equal, however; there are many different brands and models available that have differing options. Before choosing a DSL modem, take careful consideration of the different features available to make sure you find the modem that best fits the needs of your home or office network.

Instructions

1. Take stock of how much room is available on your desk to place the modem. Choose a smaller modem if you don't have much desk space, such as the "3Com 80-003615-00," which is less than 5 inches long.

2. Consider if you plan on switching to a cable service or upgrading to a T-1 line in the future. Choose a modem that can interface with a DSL, cable or T-1 line such as "ADC Kentrox 51-3W" if you want to upgrade your network later on.

3. Decide if you want any extra features beyond simply web surfing. Go with a DSL modem such as the "Actiontec GT701C" if you want to be able to save voice mails through your Internet connection directly to your computer's hard drive.

4. Pick a more expensive DSL modem that has higher upload and download speeds if you want a faster surfing experience. Pick a DSL modem such as the "3Com HomeConnect 3CP3647" for a download speed of 8 megabytes per second.

5. Check the warranty provided through the DSL modem's manufacturer. Pick a modem with a two-year replacement warranty, such as "ZyXEL P870M-I1", if you are worried about mechanical failures or power surges.

6. Pick a dual-purpose DSL modem if you want to set up a network in your home. Go with a model such as the "Actiontec GT724R", which includes the functionality of an Ethernet router along with its modem capabilities.

Tips & Warnings

• Your maximum upload and download speed are determined by your Internet provider. Don't buy a higher-priced modem with 8 megabyte download speeds if your Internet service provider only offers 3 megabyte download speeds.

• Read through the system requirements of the DSL modem before making a purchase. While the "Motorola 1431182" DSL modem is compatible with a Mac computer, many others are not.
