AIRCARD 340u

[JeffMartz]

I insert SIM card. Plug device into Macbook Pro 2016 using USB-C dongle. It powers up. "Ready to connect" displayed on the screen and that's it. Nothing shows up on the Macbook. I followed the instructions in the solved thread by installing the new driver that was released in October and the watcher software never shows up. I see it in my network interfaces, the computer is seeing the device the software is just not installing for me. I downloaded AT&T's software and it opens up but tells me there is no device connected.

I can confirm the same thing happens on my Windows 10 machine. Modem powers up, says "ready to connect" but I have no way to make it actually connect.  Let me ask the obvious question. Why are we jumping through hoops to get this thing working? It's an AT&T device with an AT&T SIM installed. I should plug it in and it should just work. Alcatel W800 I put T-MOBILE SIM card in and plugged it into this same laptop and it was working within seconds providing a fantastic connection. Unfortunately it doesn't work with AT&T.

I'm getting ready to send this piece of crap back to Amazon. It's probably filled with security holes like your routers anyway.

Plug the device into the Mac, open the downloaded Sierra file and open the folder and install the file labeled Drivers_10.9.pkg. The Mac will direct you to restart, once it restarts, open the Aircard Watcher app and give it a bit then the device will be recognized and you'll be good to go.
