TeleopPeriodic doesn't seem to iterate fast enough to smoothly run motors

if you have a bad WiFi signal or other cause of substantial packet loss, it could be much slower.

This is distinctly possible, I hadn't thought to check latency. I'll report back once I'm able to test again this evening. If it is latency, what might be causing it? The computer running the code was in the same room as the router. Come to think of it, the code was deployed from a computer which is not the classmate, and may have had a firewall, etc. Could that be the cause? Thanks.
