They are Grad students, they DON'T have lives of their own.

Having said that I will repeat my claim that the robot is protected by WPA encryption when on the field. WPA encryption has not been fully cracked to my knowledge, although there are vulnerabilities with the handshaking which allow for offline dictionary attacks. I don't recall the exact length or nature of the keys in use but I believe they are randomly generated keys that at the very least contain lower case, upper case and digits. A key generated in this fashion, even of the minimum 8 characters, should take far too long to brute force unless you are extremely lucky.

If I am wrong and you have a way to crack a WPA key in a timeframe that would be useful for attacking the FRC network please let me know what it is via PM and I will gladly test it and agree with you after confirming it works.

An FTP password would either be obnoxious for teams (randomly generated) or more vulnerable to a dictionary attack than the WPA key (team chosen)

The issue I mentioned before is that you don't NEED to break the WPA key (which I can do fairly consistently in less than ~30 mins).

All you have to do for this system is make the wireless 'reconnect', which will make it reconnect, thus getting stuck in 'disabled' mode for the rest of the match. Making the wireless connection reset is extremely easy, and I'll leave googling it as an exercise to the reader.

Since hacking a WPA key takes a short period of time, a person in the stands could capture the hash during practice/qual matches, then crack them at their convenience. This would allow the person to alter the assembly on the cRio at the wrong time, which I would imagine could cause immense problems.
