Why won't my rrw wireless show up?

So i have roadrunner wireless by twc and it usually works but today it wouldnt show up on me or my dads android and my brothers iphone. It also won't show up on my laptop. What can i do i have restarted it and now i don't know what to do?

Added (1). it does have a password and i connected a desktop via cable and it works just fine so

Added (2). but the wireless part doesn't work still and i still don't know what to d o

It is possible it was not password protected and someone disabled the wireless network/signal.

Connect a device via a cable and test the internet. If it works, chances are that this is it. If the wi-fi is enabled, then your router's wi-fi adapter decided to break today.
