Forgot password for Airport Extreme

I'm using a Mac Air, and deduced from what I read online that I needed to download the app. I tried to do so on my laptop, but couldn't, so I downloaded it to my iPad. Currently, I have a call scheduled today with Apple Support to help be reset the Airport base station and fix the issue (I hope).

Actually, based on your reply, I found the Airport Extreme utility in my Mac Air's Applications, and was able to update the firmware and now the light is green and WiFi is connected (it scared me for a few minutes because it took so long, and there was an error message, but all seems to be OK - I will keep my phone appointment just to have help in checking that it's updated and properly reconnected.) Thanks, Bob!
