Windows 7 offer its user compatibility with any DSL service. DSL service is a WAy for you to connect to the internet. ATT provides the service for you to do so, just make sure your Ethernet cable (looks like an oversized telephone cord, also known as CAT5, CAT5e) is hooked into your ethernet adapter.
To be sure, you can also just contact your ISP (which is AT&T).
