Hello, I have a MacBook, and ever since I moved, I have been having problems connecting to wifi. The city of Philadelphia has their own free wireless and there are other insecure networks that my airport picks up. It will stay connected to any of these networks for only a few minutes and then disconnects. I cannot help but think it is something wrong with my airport or network preferences, because my roommate's MacBook has full connectivity on these networks and stays connected. Is there anything I can do about this? Thanks!
