iPad Mini will not connect WIFI with JetPACK

Verizon Jetpack AC791L.

Firmware: Updated, on both iPad mini and Jetpack.
IPad Mini: ME280LL/A

I have 3 other iPads and 3 other MacBook Pros and 1 MacBook AIR. NONE of these have a problem connecting with anything.

The iPad mini that I am discussing connects with an older version of the Jetpack that we have (we have 2).

The new JetPack will not connect with this iPad mini and only this device.

Please provide succinct answers specific to the iPAD mini. I have seen too many misguided answers and have been down several rabbit trails.

The problem is that the iPad mini is not accepting the JetPack password. It doesn't say it is invalid, it just comes back with the "enter the password" dialog.

Please advise.
