MiFi 4510L gets stuck in "dormant" state

[nsayer]

Firmware v2.23 is far and away better than the older firmware, but still, once or twice a week, the device will fail. The symptoms:

1. WiFi is still connected, but any data I/O simply hangs.

2. vz.hotspot responds, and shows the connection state correctly, except that it is "dormant."

Hitting "Disconnect" waiting and then hitting "connect" works around the problem and brings the connection back up.

The "dormant" state is not sufficient to identify this problem - the mifi connection is often dormant, but when you start doing something, it typically "un-dormants" itself and operates normally. Only sometimes - once or twice a week for me - does it wind up in a state of semi-permanent dormancy.

The "Dormant" problem has been around for years and still no fix.  It is not a power problem, it is a technology problem.  Not knowing the exact details, I will not elaborate on the issue.  The fact that it occurs only with LTE and not CDMA is somewhat peculiar, is VZW pushing something they cannot fully support?  All I know for sure the the "Dormant" problem is real, a connection that goes dormant will downloading data is unacceptable.  Verizon expects me to pay them every month and I expect the services to work. Someone is not fulfilling their end of the bargain, only a few months left then back to AT&T or I give Sprint a try.

You are absolutely correct.  The Dormant issue is IS a problem and is NOT normal behavior for a mobile data device.  It IS normal behavior for the 4150, which IS a problem.  There is a lot of conjecture here defending the 4150, but it is faulty.  If in fact the 4150 is performing as designed, then the original design parameters and requiremens are erroneous. 

I have now proven that the 4150 is in fact behaving improperly - conclusively.  Side by side, at the same location, on the same networks, exercising the same exact test scripts, at the exact same time, a PC connected via the 4150 experiences the "dormancy" and "lockup" issues while right next to it a PC connected via an LTE equipped iPad does not.  Consistently.  Routinely.  After the 4150 has been upgraded, swapped out, tested, wiped and reconfigured, etc.  Furthermore, this situation is replicated in multiple geographic locations.  It is now abundantly clear that the 4150 has inherent design flaws that cannot be corrected by the troubleshooting indicated on this site, or by VZ.  My 4150 has now been shut down, and will forever live as a example of one of the worst supported devices in history. 

On another note, the iPad w/LTE is not perfect, but it's far better in performance.  There are some odd quirks that need to be addressed, but they are in no way to the same level as the horrible 4150.
