I am in possession of Mac book pro OS X 10.7.5, whenever I try to connect my Reliance netconnect + ZTE MT USB Modem, to it, it connects to internet but within few seconds a message pops up "you need to restart your Mac book. Keep the power button pressed untill it shuts down. Press power switch again to start your computer." I am not able to continue surfing or download anything. I have no clue why this is happening.
