dont go for railwire its useless they dont give constant speed i am using 4Mbps speed i get the speed only in night but in day it slow to 800 - 600kbs from 10am to 8pm when ever i call to customer care they are one type of idiot keep on saying the same record check ping, connect direct ect... i think 256kps of bsnl or airtel is equal of 4mbps of railwire
