To All those suffering with the 4G LTE Router..Final Solutions (Disconnections, etc)

Question

I wanted to post an update for everyone on this forum.. I've had several threads in here about my MBR Disconnecting randomly as well as it not
passing traffic for Citrix clients, etc.  I've spoke with some high level VZ techs and managers and found that this is all related to the firmware on
the units. The upper level people at VZ know this MBR is garbage in it's current state and are looking to get a new firmware release out soon..
who knows how soon.  The techs I worked with said the only solution for they have been able to provide is either to: 1. Assign a Static IP to the
device (which costs a lot) or 2. Try a new SIM card.   The tech I worked with handles business accts only and he personally has helped over 20 people with this same exact issue.  He said there are definite problems with the firmware and this device shouldn't have been released until these items were fixed.
I wish they would tell the poor 1st level VZ techs this same info. You can do all the resets/reboots you want and it's not going to fix the problem.
He also stated the firmware is so flaky that what works in one instance will almost never work somewhere else.. it's completely random.
Since my company does over spends over a million dollars a year with VZ they were able to get me a Static IP address..but I wasn't even able to
change the APN in the settings. He also said this is flaky bc some MBRs let you change it and others do not (even with the same firmware).  The
static IP is supposed to be automatically assigned when the device is reset to factory defaults so I tried that about 50 times and it still didn't work.
I even tried the NON-VZ Netgear N300 unit I had purchased as a test and I was able to put in the correct APN, but it too would not pull the static IP
even after several factory resets over a 2 day period. Both units were total garbage..
Finally I tried putting the SIM into an old Pantech UML290 USB modem I had and guess what??? It immediately pulled the Static IP and worked
perfectly.  I've been running the UML290 in an old Cradlepoint router and the service has been FLAWLESS for over a week now.. NO DROPPED
connections, NO FLAKY traffic blocking, etc.  Just works perfect as it should.. So I'm sorry to say this but until VZ comes out with a new firmware
release for this 4G Router you are out of luck.   I plan on using this current UML290 + Cradlepoint setup indefinitely or until they prove the issues
with the 4G router are fixed.  Wish I had better news,, but hopefully this will save some of you from sitting on hold with VZ tech support for days
as they run you in circles and tell you to call Netgear to fix the problems....

Excellent post creosote7, thank you very much!  Fortunately I came in here first before even trying to talk by phone to anyone about this.  I have exactly the issues you describe ... inability to play nice with Citrix VPN, and constant drop-offs, connection unavailables, etc.  Being the old Microsoft tech that I am, I just reboot the device and wait until it connects again, after which is usually good for an hour or so.  But I have it connected to a backup battery, so I know it's not flakiness from poor line condition.
What really puzzles me is how it worked fine for a week and then dies, just as AshLee52 reports.  I looked at my usage, and sure enough it was working fine enough to pull about a gig a day for the first 7 days I had it (I had to learn the hard way that my company put MozyPro on my laptop and set it to back up 4GB a day. AGGGH).  But then all of a sudden it drops off.  This smells very highly of Verizon throttling us rather than a firmware issue.
That said, firmware updates have been the fix for me for many a switch, router, and pc problem over the years, let's hope you're right and they release something soon. 
Thank goodnes I kept my DSL ... it's slower but has been my lifeline for getting my job done.  For anyone reading, I happen to also have a Verizon 4G wireless hotspot (the little hocky puck style) as well which works fantastically at the same location, so the connectivity issues are definitely tied to this LTE Home router or the VZ home service.
