What OS are you using?
Ah, ok. We will try disabling/enabling the network adaptor when it happens again. We are using Windows 10. I wonder if there is a way to prevent it from happening? It happens on all of the Windows 10 laptops we have tried which leads me to believe it's a Windows 10 issue. I did notice my Mac doesn't have the issue - Eclipse is able to connect and deploy code again after restarting the robot without having to change settings or restart the computer.

Our Windows 7 Classmate we got in the KOP last year won't even connect to the radio at all so we had to switch to another laptop.

The radio dropping in and out was probably due to a crowded 2.4GHz band or the particular automatic channel selection being too busy.
The real field is much better at coordinating robot channels, or asking the venues to turn off the access points or 5GHz bands in the area.
Yeah, I figured it was probably due to all the robot networks in the area.

Based on your robot's over response you may want to tinker with the motor safety margin and how your code sets motors only when new driver packets come it.
I will look into the code. What do you mean by motor safety margin? (I know how to enable motor safety, actually I think it actually may be disabled for RobotDrive motors which may be the issue.) And I'm not sure how to make it set the motors only when new driver packets come in - or is that what motor safety does?

Thank you for the suggestions!
