The device is basically a rebranded clearwire device. Originally when ordering it, there didn't appear to be linux support but I was hopeful. When the device arrived, I plugged it in, and it WORKED!!! No issues!!!
Now I'm thinking of adding it to a dreamplug in a remote location (but not so remote that it doesn't have 4G).
The device doesn't require a connection manager and linux sees it as a hardwired connection eth2. I will do additional testing tomorrow. Wonder how the other freedompop/clearwire devices holdup.
Also wonder when freedompop will fix their 'friend' feature.
