Wifi Providers

I live in Indira Nagar A-Block and have been using Excitel since 3 years.The speed is always good but frequent disconnection and the price increase every year is pushing me to check for others. Can anyone tell me about your experience with your broadbands. Alternatives that I found were 1. Tachyon 2. Timbl 3. Comway I don't know which one is good. as everyone is using Airtel,jio or Excitel. Kindly share your experiences and suggestions.
