MOFI-4500 replacement question

[HereComesTheRooter]

Greetings.

I switched from ADSL to a MOFI-4500 on T-Mobile's One plan (with a VPN) using two 6' Yagi antennas around the beginning of this year and have been pretty happy overall. However, within the past few months we've been seeing frequent (5 to 25X a day) brief disconnects. The MOFI isn't giving much in the way of log data indicating what's going on, and I initially suspected it was the modem resetting because of the meager 1A wall-wart power supply. I replaced it with a 2A unit and the problem persisted. I then replaced it with a 3A unit, and the problem still persists. Now I'm ready to start all over hardware-wise.

The WE826-T2 with EM7565 tutorial caught my eye for the potential of faster speeds over the EM7455 that's in my MOFI. However, I'm not sure it will address my frequent drops since it's awfully close to the same hardware with an updated modem. And I have another wish requirement for a replacement system that I haven't mentioned yet...

The MOFI is located in a detached garage and connected to the Yagis via 6' LMR400 cables. The data connection from the MOFI to my pfSense firewall system is through about 50' of Cat-6 ethernet in a buried conduit. Another problem in my rural location is relatively frequent utility power drops (not 5X a day frequent, but frequent enough to be annoying). The garage gets warm in the summer and cold in the winter*, so a lead-acid UPS isn't really an option. I'd like to know if there is a way to run an EM7565 modem in my garage and near my Yagis using Power over Ethernet (PoE) before it gets to my pfSense box. I could use a UPS on the PoE injector/switch in my house if such a solution exists.

Does such a solution exist?

*- The garage temperature has been very temperate over the past few weeks (daytime temps in the 70's and nighttime temps in the 40's, so I really don't think the connection drops are related to temperature.

You can use the RJ45 Waterproof IP67 Bulkhead Connector With Ethernet And 2.1MM Jumper Cable to plug into the router, and then power it with a 12V PoE adapter injector.

Note, that the PoE splitter above is 100M.

If you wanted to run with a 1000M (Gigabit) setup, you can use the 48V To 12V 3A POE+ Gigabit Splitter – 5.5mm X 2.1mm Power Plug Tip, and power it with a 48V PoE adapter/injector.

If I was going to build an EM7565 router, I would go with the latter option.

Thank you Jim! I've ordered one of the Gb splitters, even though I know my current speeds will get nowhere close to that. This solves my backup power issue.

Now I need to figure out this intermittent drop issue...
