Connection issues at regionals

I assume that you mean the Comm light on the actual roboRIO, not on the DS. My first idea is that you have two instances of the driver station software running on your computer, possibly in different user accounts. I suggest you do a restart of your computer while in the queue to avoid this issue.

I don't think it is due to a difference in boot time on the radio and roboRIO, since every team is using the same roboRIO and radio, including the firmware.

There is a (small) chance that there is a problem with the image on your roboRIO, but I would rule it out because you replicated the problem with other roboRIOs.
