On practice day the field was refusing connects from our team and many veteran teams. The DS laptop would connect, then immediately loose connection to the field. After much trying (4 hours) and approx 12 teams of the 50 there could not connect, it was discovered that radios at version 1.4 were the common thread. We had our radio which worked flawlessly at 1.4 in Knoxville, had it reimaged to 1.2. After which we could connect but images from the camera and control response was definitely laggy'er than at the previous competition. FIRST field personel did everything to have buiding wifi networks shutdown, (on thursday there were over a dozen non-First networks in range) and after warning the crowd to turn off their mobile wifi things got a bit better. But our DS logs do show incredible packet loss on practice thursday. The field in GTR West was the same field used earlier at GTR EAST (which we did not participate in) and First I suspect are still scratching their heads on this one. I wonder if there is any software/hardware version differences of importance between the field used at Knoxville TN and the GTR West? If other fields are having difficulty with 1.4 firmware and how this compares to the configuration of TN?
