Ok, after almost a year i finally have a setup as close to 'working' as it can get on that piece of...engineering (mk4).
The ONLY way for it to work and not reboot at the fisrt sign of any real load is:
Anker 14400mah 12v output to -> Mk4
Mk4 USB -> 4 port usb hub (NON POWERED!!!)
4 port hub -> 2gb flash stick (NOT SANDISK!!!!)
-> 3g stick
-> NHA from 'elite' set
This way it works - jammer is running on wlan1, karma and sslstrip on wlan0+3g, two reverse ssh tunnels (shell and webface).
Powered hub = fail. Any other power source (non a/c) = fail. Sandisk stick = fail.
Hope this helps, as there's still no updates from the team.
Oh, and it's on 2.8.1.
3.0 was stillborn...
