Hi, Please close this as the problem is back. It takes about an hour for it to show up. I've reported the issue to the kernel bugzilla as it looks like a driver/firmware issue (same h/w works in Windows 10). Thanks.

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.
