I'm using a Pilot Aware classic.
It's powered by an Anker 20100 power bank.
I regularly find that the wifi network disappears. To be clear, I don't mean that my tablet just disconnects from the Pilot Aware network, but rather that the network disappears altogether. So search for it to rejoin results in no network found. The only solution is to power down the PA, and power it up again.
When I connect it first, it often fails very quickly. After 3 or 4 reboots, it tends to become more stable, but even in flight, I'll usually have to reboot it once or twice.
I've two different Anker Power banks and the same thing happens with both. I've put a USB meter on it, and don't see any voltage drop.
Our aircraft recently got some USB outlets fitted and I've tried connecting to those and the same issue persists.
I bought some short, original Anker USB leads. So they should be high quality and have a very short run (about 15cm) so the cable shouldn't be an issue.
I tried turning down the wifi power on the PA, to reduce power consumption in case that was the issue, but it didn't result in any noticeable improvement.
I should say that this is a long standing problem, that I've just not got around to posting about previously.
In summary, I've tried 2 different high quality Anker Power Banks plus aircraft power, and tested with a usb meter. I've tried a number of high quality cables.
Not sure what else to try.
Is there anything that I should be looking for in the log files that might help to diagnose the issue?
