WiFi name not showing in available networks

[procrastination_foundation]

My wifi wasn't working one day, so I rebooted the router. Before, the wifi was still there, although it didn't provide internet connection. Since I've rebooted the router, all lights on the router indicate that everything is working (still green lights, no flashing) but my TV, my Samsung galaxy s7 and my mom's droid won't connect. I am assuming that there's nothing wrong with a peticular device because there are multiple devices not able to connect. I've tried unpludding and plugging back in too, btw.

How exactly did you reboot the router?
