How Can I Make AT&T DSL Wireless?

The wireless router you purchase to hook into your modem must be compatible with that modem and your computer's network cards to work properly. The four types of wireless network options are: 802.11a, 802.11b, 802.11g and 802.11n. Check the specifications for any router you intend to purchase, as well as your computer and your modem, to make sure all of your equipment is compatible. Many routers will work on several of these networks, so don't worry if your computer and modem differ. Find this information on the manufacturer's websites by entering your equipment make and model.

Purchase a router at most major electronics stores, as well as the electronics department of department stores and online. The router packaging will tell you how to set up the particular model you purchase, but in general it requires plugging the router into your modem and a power source. Once this is connected, you may need to configure the router through your wired computer connection to the modem, but many modern routers can self-configure, so if you are not comfortable with technical processes, ask the sales person which routers offer the easiest setup and best technical support.

Wireless Internet will be slower than your wired connection. The time difference may not be noticeable for general Internet browsing if your connection is strong, but you will likely notice slower download and upload speeds for large files, particularly videos and high-resolution photos. Plug your computer into an Ethernet cable to download or upload these items, and then disconnect the cable and use the wireless connection for other Internet activity.

Always secure your wireless network, even if you did not use a security code for your network when you just plugged into the DSL through an Ethernet cable. Wireless routers use microwaves and radio waves to send and receive signals, and these waves are not directed specifically between the computer and the modem. This means other computers nearby can pick up your signal. Adding password protection helps keep your Internet activity private, which is particularly important for online financial transactions.
