When using the joysticks to operate under a wireless connection we are consistently losing communication with the robot whenever suddenly going from full forward to reverse. It happens in arcade mode or in tank mode (only one joystick going from full forward to reverse in tank mode does not cause the problem). The robot then comes to a stop with the LEDs flashing on all four Victors indicating no signal and the driver station indicates no communication.

-We can regain communication by switching the driver station to disabled and then back to enabled and waiting about a minute.
-The problem happens just at the point when the motors start to reverse.
-The problem happens with the robot either up on blocks or not and we have checked our electrical contacts very carefully.
-The robot works fine in tethered mode.
-The problem does not happen if we go from forward to reverse slowly and gently.
-We are using the C++ version of the default code.
-We are using four Victor 884 motor controllers.

I suspect either the wireless router or the wireless bridge is the problem. Perhaps too much data is being generated by the joysticks for the wireless link to handle. The problem occurs only when going from full forward to reverse somewhat suddenly so we are able to get along for now, but this must not happen during competition.

Anybody else witnessed this behavior?
