The mifi will connect to the internet and sit in a "Ready" state, but once a device connects to it, it'll start an endless loop of disconnecting and trying to reconnect.
I've tried resetting, removing the SIM, disabling IPv6, cycling power, and still no luck.
Firmware is updated to 3.30.13
Sounds like the Jetpack is defective. If you are still covered under the one year warranty then contact VZW for replacement options. They should be able to quickly troubleshoot and offer you your choices.
YIKES! Seems like the device has a mind of it's own. Let's make sure we look into this a little deeper. I am going to send you a Direct Message so we can go over the account specifics. Please respond back to that message for me.
