Nighthawk M1 NTG9X50C_12.05.05.14 Firmware Issues

[S36]

My Nighthawk was functionion perfectly fine, AT&T pushed this NTG9X50C_12.05.05.14 firmware update, and now it's nothing but disconnects; several a minute at times. This is unbelievable. 

I've already factory reset the device, yet continue to have these issues where the internet stalls, or the device is frantically connecting to different bands and ultimately loses "connected" status. My signal is "Good" LTE. Before the update, I would constantly get 80-95 Mbps down/ 45-50 Mbps Up and NO disconnects when it'd utilize B2 band.

What can I expect?

I had prefect internet until this morning and all of the sudden my internet stopped working. I check the hotspot and found that even with 2-3 bars it keeps saying mobile boardnband disconnected, your data connection is disconnected. I have tried restarting and resetting the hotspot without any luck. It would appear that my devise updaed the firmware this morning and now I have no internet.
