I played cod 4 through game ranger at my friends house in Barisal with his 512 kbps banglalion connection. he uses an indoor modem with wifi router. i have tried playing in Pirojpur with banglalion usb dongle modem and it's horrible. ping is more than 300. the banglalion network in Pirojpur is really bad. if I try in Barisal, where the signal is excellent, will I be able to play ? or, it's just an indoor modem is required for better ping ?
