Hi.. I'm running into the same issue with Central and IAP.
The error I get is as below. After a few minutes the dongle reboots.
I tried with 8.6 and 8.7, still no luck
Is it something to do with the ip pass thru vs nat mode?
It is able to recognize it but unable to connect.
I used it on another 4g usb router (MR3020) and it works.

ok that modem has to be set to operate in enterprise mode. You can connect the modem to your laptop and basically try to get to the modem's web interface, there you can upgrade the modem's firmware and also enable enterprise mode.
