Configuring a DSL Modem

Manually configuring your own DSL Internet connection is a fairly simple process. However, if you don't do it properly, you will end up with many problems. As long as you know exactly what type of DSL service you have, the process of setting up your modem should go very


Types
The most common type of DSL service is asymmetric DSL (ADSL). ADSL has faster download speeds than upload speeds. This differs from symmetric DSL (SDSL), in which download and upload speeds are equal. There are also many different types of DSL modems. Some come with a built-in firewall or a wireless router. Some have only Ethernet connections, whereas others have a USB port as well. If you're buying your own modem, be sure to contact your service provider to determine which type to get.

Features
Most DSL modems come with a power adapter, a telephone cable, a phone filter and an Ethernet cable. You must have a network card on your computer to connect the Ethernet cable. If you don't have a network card, you may be able to attach your modem by USB. Follow the modem manufacturer's instructions for physical installation of the modem before attempting to configure it. Also speak to your service provider in advance to determine which type of connection you have and to get your username and password. In Windows, click Start > Control Panel. Select "Network and Internet Connections." Then select "Network Connections." Under "Network Tasks," click "Create a New Connection." The "New Connection Wizard" will open. Click "Next." Under "Network Connection Type" select "Connect to the Internet." Click "Next" again. In the next screen, select "Set up my connection manually." Continue to the next screen. Select whether or not your connection uses a username and password. Enter the name of your connection, username and password in the next two screens if necessary.
Function
DSL operates on frequencies that are unused in telephone transmissions. Make sure that you install the phone filters not only on the telephone line that you use to connect to your modem, but also on all other phone outlets in your home or office. A common type of DSL connection, Point to Point Protocol over Ethernet (PPPoE), uses a username and password to log you onto the Internet.

Benefits

If you don't want to install the software that came with your Internet service, configuring your DSL manually is a must. If the service provider's software is causing serious problems on your computer, you can completely uninstall it without losing your connection. This will free up your memory to run other applications, since the ISP's software will no longer be loaded every time you start your computer.

Considerations

Even though you log in to your connection with PPPoE, it will probably be on all the time. For this reason, you should make sure that your firewall is active at all times and that you have current anti-virus software installed. Also, if you plan to install a local area network (LAN) you will have to re-route your Ethernet connection. Properly connected, the DSL modem will connect to your network router, which will attach directly to the Ethernet port of your computer.
