hi friends

my name is swaroop from hyderabad, i got sify broadband 256kbps night and weekend unlimited plan for Rs.576, i like to change to TATA or some other broadband, because in sify the download speed is very slow it start at around 20kbps at 10.00pm, at 1.00pm reaches to 40kbps,in morning it decreases to 20kbps, presently i want to switch to unlimited 24hrs plan, with very good download speed

Please suggest me based on your experience which broadband is best, and which plan, i dont have airtel service in my area, so any other
