^ The DSL ID is usually your complete phone number, STD included, appended with a _dsl. If your number is something like 08040404040, the ID should be 08040404040_dsl, and the password 08040404040. If that doesn't work, try appending @airtelbroadband.in to your ID, like 08040404040_dsl@airtelbroadband.in . If neither helps, CC is always there.
