Constant loss of connection

[deHakkelaar]

Next question, how do you disable power saving for on board WiFi on a Pi3 if its not in the parameters ?
Is this done in "interfaces" with the "wireless-power off" directive ?
Makes me wonder if its working at all.
For diagnosing, one could leave a ping running (keep alive) so the adapter doesnt fall asleep for sure eg:

Terminal

$ ping -i 30 -q $(sudo route -n | grep 'UG[ \t]' | awk '{print $2}') &
[1] 28888
PING 10.0.0.1 (10.0.0.1) 56(84) bytes of data.
$

Terminal

$ jobs
[1]+ Running ping -i 30 -q $(sudo route -n | grep 'UG[ \t]' | awk '{print $2}') &
$

Terminal

$ fg 1
ping -i 30 -q $(sudo route -n | grep 'UG[ \t]' | awk '{print $2}')
^C
