Hi Kenton,
Team 2930 is experiencing the same problems. While we haven't had time to debug because of snow days the last couple days, I did a search on CD and found
this thread from last year. Some of CD's most helpful and knowledgeable people had some insight into the problem:

Another solution is to leave the laptop on and plugged in overnight and let it finish its background stuff so that it will leave you alone. But I prefer to turn these things off as it will come back to life in the future and cause the same issues.

Look for it in your add/remove programs. Or if you want to keep autodesk, Akamai has an interface options menu. You can Disable it. That will effectively kill the net connection for Akamai and then you shouldn't experience the loss as well!
Hope this helps!

Consider switching to the 5Ghz WiFi band (802.11ac), if your laptop supports that.
Check the bandwidth usage from your laptop using the steps found here.

Last night, the robot was on channel 1 and everything was fine. We also learned that the team's new laptops only support 2.4 GHz. So we setup another router to bridge 5GHz so we can grab it if needed.

Based on this, I think 2930's next steps for debugging this problem will be to check for background tasks which have CPU spikes during the same time as the packet loss spikes, and try to disable any suspicious tasks. If nothing is found on this front, we will try the 5GHz connection.
Hope you find a solution to your problems! If you are successful, please post on here for the rest of us!
