Netgear Aircard 306u (csl Drivers For Mac

I upgraded my MacBook Pro to Apple Sierra macOS 10.12 and I can no longer use my 340U device. I have tried the AT&T All Access connection manager and also the Netgear Watcher software. Both of the software application do not detect the device plugged in. I know the device is working because I can plug it into a PC and it works fine.
