While trying to debug poor video chat quality, I noticed that certain apps cause periodic ping latency spikes even while pinging my router.
I tracked the problem down to the fact that the apps (e.g. Genymotion, qbittorrent) seem to be scanning for wifi networks every few seconds. (When I turned on debug wifi logging, I kept seeing lines like
Info: <airportd> SCAN request received from pid 76811 (genymotion) with priority 0 that correlated with the latency spikes.)
Is there any way for me to stop this from happening? It basically means I can't run Genymotion and have a video call at the same time because it'll stutter every 10-15 seconds.
