Great informations about unlimited broadband plan:

Reasons for slow internet connection - (As per the Airtel Field Engineer statement)

* Airtel provides broadband as dedicated port for every users, but its shared bandwidth (If more user access might lead to slow the speed of your connection), but its not dedicated bandwidth that was offerred then what is the use of dedicated port ? and due to copper connection (the cable) you may experiences 20% loss of the actual broadband what they offer.

So 20% + shared bandwidth will decided the speed of your connection.

Note: currently I am using 256 Kbps plans, but receving 170 Kbps only and above is the detailed information or support provided as explaination.

No online or written or signup form does not mention any broadband policy:

* Airtel does not have any website/webpage to show there customer or educate the customer about the broadband policy... like how to claim refund, if the issue or problems was not resolved with in the stipulated time as promised and what will be offered to the customer as compensation in means of subscription or money or detection in the monthly bill or offers etc.

Note: When requested the company policy, they claim to check the "Telecom Regulatory Authority of India" web policy...what an idea! It seems Airtel does not have any policy.... to backup...
