I've been having this problem for a few months now, and have not been able to figure out what the problem is. I've noticed that when I'm on a video conference call, every few minutes, the video and audio will freeze for about 2-3 seconds. To test my network connection, I decided to set up a ping to google (and my router), and noticed that whenever the network interruption would occur, my pings would timeout. I've tested doing concurrent pings with 2 machines side by side, and can see that the other machine pings just fine during the period mine is acting up. Here's an example of what I see when I'm pinging:

The problem seems to get temporary better after a restart, but eventually comes back. I've tried closing most everything on my computer, but the problem persists. I'm at a loss as to what could be wrong, and I'm hoping this community can offer some assistance and troubleshooting steps.
EDIT: I've added sections from a longer trace. There's 1 ping every second, and breaking down the time between failures, we get the following intervals:
1-2: 182 seconds
2-3: 179 seconds
3-4: 179 seconds
4-5: 181 seconds
5-6: 178 seconds
From this, you can see I'm averaging a failure every 3 minutes (almost to the second). I have no idea what would be running every 3 minutes that would cause this issue.
EDIT2: Here are my system specs:
Model Name: MacBook Pro
Model Identifier: MacBookPro14,3
Processor Name: Intel Core i7
Processor Speed: 3.1 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 8 MB
Hyper-Threading Technology: Enabled
Memory: 16 GB
Boot ROM Version: 198.0.0.0.0
SMC Version (system): 2.45f0
EDIT3: I tried hooking up my computer to the ethernet port, and the problem seemed to go away, but came back when I switched to wireless. The other devices I tested on were also wireless, so I still feel that it's something to do with my computer, but specifically something with the wireless signal.
