Compatibility Report: Sierra MC7354 Mini-pcie LTE

Hardware MikroTik hardware general
36

Hello:

This topic is 3 years old, but it is relevant to my current problem. I wanted to use the Sierra MC7354 with Verizon. We have used a lot of MC7354 cads with AT&T, but never Verizon.
So I searched and searched for information and this thread is the most promising (although I have tried a lot of other things from many other sources).
Several posts on this topic indicated working units with Verizon.

This is specific to Verizon in the USA, where I am located.

Here is what I did (I tried this with a BaseBox and a wAP R)

  1. Received a Verizon SIM and activated it in a Verizon USB551L (everything went great and it worked on my laptop)
  2. Mounted the MC7354 in a USB to PCIe interface and connected to my laptop[/list]
  3. Downloaded latest firmware from Sierra and flashed the card (success)
  4. Inserted the Verizon SIM into the USB to PCIe device, connected an LTE antenna and successfully connected to the Internet using the USB/Sierra/SIM combo
  5. Mounted the MC7354 into a Mikrotik wAP R, connected internal antennas, inserted SIIM
  6. Updated Mikrotik to ROS 6.42.6
  7. Executed ‘/sys routerboard usb set type=mini-PCIe’
  8. Got the ppp-out1 interface, configured it with: data channel=2, info channel=2, APN=vzwinternet, dial command=ATDT -the rest I left at defaults
  9. Added a firewall filter as recommended in this topic: http://forum.mikrotik.com/t/need-help-with-a-verizon-usb760-3g-card/35398/1 (somewhat related information)
  10. Added a masqurade rule for traffic going out the ppp-out1 interface

Problem:
I watch the logs and I see that I get all the way to “connected”, with an IP address, then 5-15 seconds later, disconnect.
It will keep trying and every 3-6 tries it will get a connect for a short time, then a disconnect.
I think as soon as any data goes out the interface it disconnects (a little bit of a guess)
I have tried different APN (internet, vzwinternet, and )
I tried various dial numbers that were suggested from old posts.
I found a webpage where someone got Verizon working on a R11e-LTE-US - and I have one of those, but specs show it does not support Verizon’s main channel: 13

I am no “expert” on LTE communications, we primarily use it to setup our clients with “fail-over” in case the main ISP fails. And we have always used AT&T up until now.

Any help or guidance would be appreciated. Maybe MC7354 is just not supported anymore…

Thank you!
