I had a gateway computer from verizon with 3G wifi installed that worked perfect. Computer crashed so I got a new netbook and purchased the MIFI 4510L. The device connectivity is horrible while traveling around in Louisville, KY. I had to exchange after the first day but the problems continue. The device goes in and out and kicks me off and is only in 3G. The violet light will blink and then stop every 20 seconds but if I touch the mouse it will start blinking again. The device will not keeping charging until the bars are full either which is intermittent. Any suggestions on getting reliable service while on the move. Should I go back to an old 3G device?
