TonyMac32 Posted February 22, 2019 Posted February 22, 2019 Not much of a tutorial, but it is something that often needs some googling and head scratching. This is how I got my particular modem working, your mileage may vary. Step 1) Get a modem that will work. I got a Huawei E397u LTE/UMTS/GSM modem. It's Cricket branded, but I'm on Google Fi, it will work with my data SIM. Step 2) Plug it in and see that it doesn't work. Step 3a) apt update Step 3b) apt upgrade Step 4) Install usb-modeswitcher Step 4, optional part 2) install modem-manager, modem-manager-gui (for general playing around) Step 5) unplug/replug the USB modem, see that it should magically have a different VID:PID when you type lsusb. You should also have some ttyUSB's, and you can check out modem details in the modem-manager-gui Step 6) set up network connection via the network dropdown at the top right of the desktop. You will need APN information for your carrier. I put in modem-manager so I could debug. It will cause issues if you do certain things with it while connected. My modem was $15, Ebay has them. https://www.ebay.com/itm/BRAND-NEW-Unlocked-Cricket-Huawei-E397-E397u-53-4G-LTE-Mobile-Broadband-Modem/262898110276 So does amazon. 1
