USB760 AirCard works fine with my laptop computer but will only connect to thedesktop's verizon wireless broadband access for a minute or two at a time before the connection goes dormant and then disconnects shortly afterward. I cannot figure out why it will not stay connected. Any help would be greatly appreciated.
