I have been using Airtel broadband for more than five years. The service was good and there were times when we were having hassle free connections.
Nowadays, that is not the case. There are quite a few times my broadband connection goes off when there is slight rain or climatic change.
Not sure if it is because of too many local competitors who have evolved off late, but this is happening. With 4g in line, airtel should provide better service. Also, the cost of internet should come down overall. Everyday the amount of internet users are increasing and the rates keep increasing too. There should be internet connections at cheaper prices.
