Hi @Daydreamer,
We definitely need more information on this one, but a common fix to most Wi-Fi issues is to remove and reconnect to the Wi-Fi connection.
To do this go to Settings > Wi-Fi > Tap and hold on your Wi-Fi connection > Remove. Then, reconnect to your Wi-Fi.
"No wi-fi connection shows up, it just says no network's available"
Try following, before procceding:
1.) Enable/Disable Wifi and see, if your Smartphone connects.
If that's not working

2.) Start your Smartphone in Safe-Mode.

3.) Look, if Wi-Fi is Enabled from your Network Device (The router in that case) by using your laptop or another Smartphone
If that's not working

4.) Please go to Settings-->About-->Diagnose-Wireless-->Wi-Fi
