Public bug reported:
While using Wi-Fi and Bluetooth A2DP together there was stuttering on my
headset. I noticed that the interruptions were happening at constant
intervals and wondered if it was on account of Network Manager scanning
for access points. Forcing NM to stick to my local AP by using its BSSID
seems to have eliminated the interference/stuttering almost completely.
This is with the iwlwifi driver, the chip is the Intel Wireless 3160. It
could be that the driver is buggy too but since tweaking the NM
configuration appears to fix it, perhaps something could be done there.
