I have now seen a handful of Ethernet cable failures this season. Several at the laptop (maybe 8 failures of 5 events x 40 robots). About 50% of those were classmates. I have also observed a few "bad" Ethernet cables between the robot and rio (approximately 4-6).
One item that tends to mask the poor connection issue is using a "printer cable" to directly connect into the rio during inspection. While handy, I will be even stronger in my wording with teams that they likely have a cable/connector issue they should look into in those cases.
The majority of failures have been the other "power" related failures noted by many others.
