my roommate locked me out of the wireless as a prank and now my computer wont log into the wireless network. also im getting error messages about my ip adress. any suggestions on what i can do to fix it?
Is it an Extreme or an Express? If it's an Extreme, connect to it via Ethernet and reset the password with AirPort Utility. If it's an Express, you may need to perform a factory reset. Then you should change the password to your base station and never give it to your roommate again.
