Need help in searching for alternate wired broadband service provider

I am currently using Airtel broadband but want to switch the same because of frequent technical issues that I have started facing suddenly.

I currently reside at Anupam Enclave PH-1 on IGNOU Road (Neb Sarai). Can anyone help me with this problem and suggest me any other ISP providing reliable broadband services.

Did you find anything? I am going to be moving to Freedom fighters enclave permanently and I don't think airtel broadband is available there. I am pretty happy with airtel's broadband services in Gurgaon.
