When searching for a connection AirPort came up with a strong signal from Ride Your Bike. I tried to log on but it required a password as a guest even though showing it was not encrypted. Since that time Ride Your Bike has become the default connection regardless of where I am. When I sign on to my home modem as soon as I leave the computer for a short time Ride Your Bike takes over again and I have to re-connect to my own modem. I want to remove Ride Your Bike from its self imposed default position and can't find how in "help". Perhaps I'm asking the wrong question, using the wrong words.
