BSNL gives you stable pings most of the times , i get 50-70 for mumbai servers for CS 1.6 smtimes in higher range of 160-200 which usually goes away on resetting the modem few no of times
Thanks. I will not be able to get bsnl due to some reason. I have option for Airtel - 256 kbps , Reliance 1/2 mbps and a local ISP which is will also provide 1 mbps. But I have not heard any feedback on the local ISP. Any suggestion.
