My wi-fi connection is working just fine on my desktop mac-mini and ATT iphone 4. Guests in my home cannot use my wi-fi because, apparently, when I typed the password, I messed up a character. Now I have purchased an iphone 5s, switched to a Verizon phone service, (bc my ATT connection is so bad I have to go outside to talk!) and tomorrow am switching from ATT to Charter bc it is half the monthly charge. So...I guess my question is...how do I retrieve my wi-fi password?
