I am using Vodafone 2GB 2G pack on my Samsung corby connected as a modem to my laptop. I was getting 250ms as ping and 20kbps download but from some days I am getting 1200ms as ping and 4kb download. I donít know whats going wrong, I have contacted the Vodafone customer center and they were not of much help. I just wanted to know if I can do anything to get better download speed from my end??
