I have a IR829GW-LTE-VZ-AK9 that is having some cell connection drops. It worked fine in one area (Orlando, FL), but is experiencing drops with the exact same configuration in a different area (Franklin, NC). I am using a cell booster to amplify the signal, but I don't think that is the problem. My reason for thinking that is that I also have a Verizon Jetpack Mifi (Novatel) that is in the same place and it has been totally solid. I think there is some that is annoying the VZ network and it is dropping the data call. Here is what the problem looks like when the connection drops:
.Nov 23 12:17:41 EST: %CELLWAN-2-BEARER_DELETED: Instance id=0, Default bearer (bearer_id=6) in Cellular0 is now deleted.
.Nov 23 12:17:41 EST: %CELLWAN-2-BEARER_DELETED: Instance id=0, Default bearer (bearer_id=255) in Cellular0 is now deleted.
.Nov 23 12:17:43 EST: %LINK-5-CHANGED: Interface Cellular0, changed state to reset
.Nov 23 12:17:43 EST: %DIALER-6-UNBIND: Interface Ce0 unbound from profile Di1
.Nov 23 12:17:44 EST: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0, changed state to down
.Nov 23 12:17:48 EST: %LINK-3-UPDOWN: Interface Cellular0, changed state to down
Then it comes back a few seconds later:
.Nov 23 12:17:59 EST: %CELLWAN-2-BEARER_UP: Instance id=0, Default bearer (bearer_id=6) in Cellular0 is now UP
.Nov 23 12:17:59 EST: %CELLWAN-2-BEARER_UP: Instance id=0, Default bearer (bearer_id=6) in Cellular0 is now UP
.Nov 23 12:18:01 EST: %LINK-3-UPDOWN: Interface Cellular0, changed state to up
.Nov 23 12:18:01 EST: %DIALER-6-BIND: Interface Ce0 bound to profile Di1
.Nov 23 12:18:02 EST: %LINEPROTO-5-UPDOWN: Line protocol on Interface Cellular0, changed state to up
In the connection call history, this is what I see over and over again:
tcfnc#sh cell 0 conn call
Start Time Stop Time Duration

Call disconnect reason
Call end mode = 3GPP
Session disconnect reason type = 3GPP specification defined(6)
Session disconnect reason = Regular deactivation(36)
Thu Nov 23 12:12:51 2017 Thu Nov 23 12:13:35 2017 44 seconds
Call disconnect reason
Call end mode = 3GPP
Session disconnect reason type = 3GPP specification defined(6)
Session disconnect reason = Regular deactivation(36)
Again, the signal strength looks good.

Note the strong RSSI. I thought it might be something with the MTU, that hasn't helped. Router config attached.
