Re: Robot communication issues

Based on the information you've provided, there are some elements of deterministic behavior (performs the same using any laptop & still seems to be able to download code), and some random behavior (i.e., the rare times it behaves differently). Through your troubleshooting you've already removed one source of potential randomness from consideration: It's not a wireless issue since you've tested it tethered. Are you testing the using code that is known to be operational with an older firmware version? If not, I'd recommend either reverting firmware to the previous one or using the current firmware with code that you've written that's known to work with the current firmware.

You don't say what language you are using or what type of control (e.g., Iterative). I don't have experience with the RoboRIO -- my experience is a bit more dated, so others might set me straight. However, based on the information you provided, it could be possible that your code is simply failing most of the time and dropping out the the bottom of your code. You might try wrapping all your methods in a catch block and have the contents of the catch block do something to demonstrate that the catch block was entered (e.g., turn on an LED).
