My Wi-Fi on my iPhone won't work?

I have an iPhone 5c and suddenly about an hour ago my Wi-Fi on only my iPhone (All other devices run the internet perfectly fine) and I've reset both my iPhone and internet multiple times. It will not show up the Wi-Fi at all and when I manually type the Wi-Fi username and password in it just says "No Wi-Fi found" please help.

Check on your iPhone if the data connection is on

Check your data connection.

Had you disabled Wi-Fi feature by accident? Try to reebable Wi-Fi. If it still couldn't work, restart your router or update the routers' firmware for solution. Or you can see more ways for solution here, http://www.mywifirouter.me/topic/six-useful-ways-help-to-solve-wifi-problems/
