Yep, I agree that Ethernet is the ideal tethering method. For us however, tethering was limited to just testing things in either our pit or in queue, and we didn't need the longer distance that Ethernet can handle. If we needed to test on the practice field or some other long distance tether we had a long Ethernet cable ready.

This is correct as well, although we didn't have issues with that this season (low goal robot ).
