I got to know about the performance of railtel broadband from one of my friend, due to very bad performance of Bsnl (3 days continous down) I changed to Do Broadband, it is very cheaper connection than any other network, the performance is also the same, then i planned to change it to railnet, i never expected they will charge Rs.5000/- (Rupees Five Thousand) for the installation, not only i had another wifi router, i asked to make use of it and they said, it will not support with railtel broadband modem and they installed one from their end, and afterwards when i connected my old wifi router and it is working perfectly.
