i got one of the 3 3g pay as you go dongle things but i have recently encountered some problems....it keeps disconnecting from the net, i have noticed when its connected to hspda it works fine but when it swithes to 3g it cuts out, i bought a new sim for the dongle and for about a week it seemed fine now its doing the exact same thing again, could the dongle be broken or could it be a setting on my computer or dongle? PLEASE HELP!!! i cant take this anymore!!!
