Description
Welcome back to Dev Odyssey Home Networking! In this episode, we learn how to create a 4G LTE Raspberry Pi Router, powered by OpenWrt 21.02 and using Verizon’s network. This video is a sequel to connecting to a cellular network over with Raspberry Pi, OpenWrt and 3G. The use cases are similar, however with faster 4G LTE speeds, this Pi can can simply do more, where faster networking is required. Cellular configuration can be finicky and greatly vary between different modem manufacturers, however if you follow the general process below, you can successfully set up your own 4G LTE Raspberry Pi OpenWrt Router!
General Process
Decide On Your Cellular Carrier
Research Carrier Documentation
Research Modem Pricing
Ensure Region Support
Check Modem IMEI With Carrier (if you already own a modem)
Use Latest Firmware

Hi, great video. I got a problem. I installed all the package, checked more then once, but I can t get confirm the interface qmi_wan and if I try the AT command AT!LTEinfo? I get an error. Can anyone help me or direct me to some info. I searched but couldn t find much.

So did you activate the sim on your phone first? Any issues from Verizon using a the sim on a non standard phone?
Question: At the software part you said you flashed the SD card with openWrt. My SD card is flashed with headless Debian so how can I flash it with openWrt? Are you saying you installed openwrt on pi?
Hello, I bought the same hardware but I'm having problems with the configuration. OpenWRT doesn't recognize EM7455. uqmi command doesn't work and Luci doesn't create DHCP client associated to the wwan connection. Any idea to resolve it?
I really appreciate you writing this tutorial but can you please add what the password is for the prebuilt image?
it´s amazing
Cool video!
I wonder if I could get something like this working on my old Pi 2 model B…
hi nice video – do you know whats the current best LTE module for the raspberry pi on the market as of 2023?
So I can use your exact 4G hardware, and get the same results?
Sir give me 1 R4S please…
I have a Mini pci-E WWAN HAT ver2.0 with sierra MC7700 network card can you help me to configure it on raspberry pi 4 4G it is if possible thank you and have a nice day
nice work, that is a very stunning talking bot you builded.

Sorry, our network no longer supports this device.

Is it possible to use GPS through this module as well? I think a use case for a vehicle LoJack system would be cool.
Your videos are so organized! keep going man, youre a star 👏
Great video! — man seeing Hayes AT commands was a blast from the past — the ghost in the machine. I'm antiipating this type of modem will be much more satisfying than hot-spot sharing over an iphone. I was thinking about setting up a Pi as a remote secuity device using a cellular modem.
is it possible to connect a raspberry pi 4g to a vps server from the 4g signal and send a wifi signal to communicate mobile devices?
Your content is awesome as there is little to no information on how these are set up. May I suggest going in depth more on the command line commands to lock and change bands, how the PCIe and M.2 protocols and ports Dev/tty/usb… setup. I want to do videos on how to set these up and info for firmware updates, what to do when you are stuck with a firmware recovery screen and how to put routers into recovery mode. Another crutial thing is setup or bands, their hex decimal and command to program groups of bands. Another hot item is how to see the available towers in your area and how to select different towers. Their is reading material available on this available but can be confusing when you want to find info for the average Joe. I knew nothing about this stuff and am self taught as my internet option was DSL.
You had slower 3G speeds than that? Damn…
Great video! Would love a 5G one!
