How to Connect to AT&T Wireless Internet Service in Your Home

Several wireless Internet providers operate across the United States, including AT&T, one of the most popular. Although AT&T offers DSL Internet, it is possible to have wireless service throughout your home. Typically, a technician will install Internet service to your home. However, it is possible to install wireless Internet yourself.

Step

Contact AT&T and have it set up DSL Internet service. You need a line-based Internet before you can activate wireless Internet.

Step

Connect an Ethernet cable into a wall outlet. Many newer homes have separate DSL outlets; most older homes require an adapter to be plugged into a phone line.

Step

Plug the other end of the Ethernet cable into the "Internet" port on the rear of a DSL modem.

Step

Insert a second Ethernet cable into the first available port next to the "Internet" port on the modem. Plug the other end of the cable into the "Internet" port on a wireless router.

Step

Power on both the wireless router and the DSL modem.

Step

Launch the web browser on your computer. Look on the bottom of the wireless router for an activation address (typically something like "http://192..."). Type this address into the URL bar of your Web browser and hit enter. This brings up the options for the router.

Step

Select "OK" for all the current options and the router activates. You can now browser the Internet wirelessly via the wireless router connected to your AT&T DSL modem.
