Before I started using C3 on a regular basis I did some tesing and I didn't notice any difference in connectivity. When running on AC the connection works for a while ( a random amount of time ) , but then the carrier is lost. When running in school I get really low transfer speed, somewhere around 200Kb/s from a computer in a room next door. When running on linux I get around 1+Mb/s from the same computer.
