My DSL internet is linked with my telephone service which is AT&T. I have had good service and no outages (knock on wood). The set-up was so easy I did it myself. I am both wired and wireless and can have up to 10 computers online at a time and it doesn't compromise the signal.
That they are offering no equipment charges and no contract (especially this) it sounds like it would be worth the try. Are there any installation charges? Are there any penalties if you unsubscribe?
