Is a LAN Line Required for DSL?
In order to access a DSL service (digital subscriber line), you need a DSL modem. A LAN (local area network) is defined as connecting two or more computers or network devices together. So, by definition, connecting a computer to a DSL modem creates a LAN. A LAN line is not required if you are using a modem with wireless LAN capabilities, because the wireless connection replaces any wires.

Connecting to a DSL Modem
-
In most cases, a computer requires a network port to connect to a modem. Use a standard category 5 network cable to connect to the DSL modem using the LAN port. The WAN (wide area network) port in the modem should be plugged into a live telephone wire once your DSL service has been activated by your service provider. From the Start menu, go to "Setting," then "Network Connections." Select "Create a new connection" to start the New Connection Wizard.
Wireless Connections
-
A wireless network is possible if your computer has wireless connectivity. Most laptops today have wireless built into the computer. Wireless adaptors are available for both laptops and desktop computers. You also need a wireless-enabled DSL modem, or a wireless-enabled router. You can plug the wireless router into the DSL modem through the LAN port. Once you have connected it, you can begin configuring your DSL connection from the New Connection Wizard on your computer.

Connecting Multiple Computers
-
You can connect multiple computers in the LAN to access the DSL modem. In this case you need a wireless router, or a router with enough network ports for each computer. For office environments with many computers, you'll need a network switch, which has many more ports than a simple router used in a home. The switch connects to the DSL modem and the computers plug into the switch.
Security
-
When selecting a router for home use, a router with firewall capabilities is a wise investment. In offices, consider a standalone firewall. This will protect your computers from malicious software on the Internet as well as any hackers who may want to gain access to your computer. Most wireless routers come with password protection to keep neighbors from using your wireless connection. Directions for setting up security precautions are available in the manufacturer's instructions.
