At GTR-W, all the teams with firmware 1.4 had difficulties connecting to the field whenever there were more than 3 robots on the field at a time. We were one of about a half a dozen teams that had to downgrade our router firmware to 1.21. The problem was first noticed on Thursday afternoon when we started getting more than 3 robots at a time for practice matches. Anytime a robot with Firmware 1.4 went out on the field and powered on, ping times for all teams would spike, and robots would start randomly dropping out and reconnecting. The running theory was that the combination of a large number of access points, and the something in the 1.4 firmware was causing communication to drop in and out. By late Thursday afternoon, everybody downgraded to 1.21, and the event ran smoothly.

Figuring out that it was specific robots that was causing the problem was tricky. We couldn't figure out how something specific to our robot was causing so many difficulties for all the other teams on the field, especially since we had already attended two other regionals, and run without a single issue at either. The FTA asked all the teams that seemed to be causing the field difficulties to check their firmware, and we realized it was the one thing we all had in common. Thinking back, I can't recall if it was something that inspectors checked that at the Championship. Does anyone else remember being asked router firmware at the Championship?

It was one of the things that each Einstein team was asked in the questionnaire we filled out.
