This is a problem especially when I'm outside. I have a 2013 Macbook Air (the newest one) I use WiFi alot. I need it 24/7 for my job. Ok, I go to a coffee shop and find their Wifi. I click on it and it prompts a Password. I ask for it and the nice waitress tells me. I input and that's that. I find out that I may have inputed the wrong password. I would like to get that Prompt and input the correct password. How the heck do I do that??? I thought Join Other Network would work but it won't prompt the password box again. I'm stuck! Please help. Thank you.
