Robot Loses Connection

[adf0221]

We are having very bad issues with our robot maintaining connection to the DriverStation when we are driving without a tether. The robot will initially connect to the radio fine but after a short time the robot will become jerky when controlling and the green lights on the driver station will flash red and then come back green. When it comes back on a message about the watchdog, which is not in our program at all, will flash on the screen before reconnecting to the radio and regaining control. We are struggling to solve this issue and cannot practice driving freely and shooting until we can find a solution. Any help is desperately needed. Thanks in advance
