I have a Rosetta unit with recommended Anker power supply, utilising the power lead supplied.
When I set the unit up in my ofice at home, it works perfectly with the wifi, no matter how many times I stop and re-start it.
When in flight, it only works intermittently. As part of the elimination process, I have used a different power supply and a different power lead with the same intermittent results.
I am wondering if the issue might be related to the vibration in the aircraft or the temperature on the top of the dash in the cockpit.
It will be interesting to know if other users have had a similar experience.
