How to Buy a DSL Modem

DSL, short for digital subscriber line, is an Internet connection that is run through high-speed DSL phone lines. A DSL modem connects those high-speed DSL phone lines and your computer, acting as a gateway to the Internet. Deciding to buy a DSL modem versus renting one can save you money in the long run, because you have to return a rented one to your DSL provider if you cancel service. There are many things to factor in when choosing which DSL modem is right for you.

Things You'll Need

• Buyer's guide (see Resources)

Instructions

1. Check with your DSL provider to see if they sell new or used DSL modems. The DSL provider may offer a discount and support in getting it set up.

2. Research the different brands of DSL modems and their average costs. Decide whether you want an internal or external modem and a wired or wireless modem. Check a buyer's guide such as Epinions.

3. Determine which modems will be compatible with your Internet connection. There are different types of DSL connections, including ADSL (asymmetrical digital subscriber line), SDSL (symmetrical digital subscriber line), HDSL (high data rate) and VDSL (very high data rate). Your DSL provider will be able to tell you which connection type you have and possibly which modems are compatible.

4. Check local electronics and computer supply stores. Watch local flyers for sales and ask the sales rep about warranties. The sales rep should be able to tell you which modems to choose from for your connection type as well.

5. Browse online retailers. The buyer's guide will offer price comparisons. Factor in shipping costs, warranties and return policies before making a decision. Many sites also have customer reviews available for each item.

6. Check online auctions such as eBay. You can narrow your search for price range and choose other options such as location, Buy It Now and payment methods. Verify which parts are coming with the modem if you choose to buy a used one. Check the seller's feedback rating and verify shipping fees before committing to a bid.
