It's wifi equipped, but the connection's terribly slow. A ping (attached) shows: - No responses for 10 seconds, then the first ping returns. (!) - This trace gets as bad as 12 seconds, but I have seen another with 20 seconds I wonder what it would take to get the bus company to talk to their radio vendor, and get a better SQM in their router and head end...
