Our team found it useful on the few occasions we could connect to it. The signal was fluctuating like crazy in the Curie pits and when I tried to connect I alternately got "The 'first' wireless network is using an Access Control List to restrict connections" and "There was an error joining the wireless network 'first';" hitting "Try Again" twenty or thirty times usually got me in, but on Saturday I couldn't connect at all. Oddly enough, the signal seemed to work better in the Dome than in the pits - I only had to "Try Again" five or six times.
All in all, a really useful service that could benefit from some relay stations or a better antenna.
