What can I do to make sure I have Wi-Fi again?

I've been on my laptop since last night, no Wi-Fi reception, so I did a network diagnostics. Problems were found, but since I have no idea of anything, I would need someone to tell me what to do now.

"Problems Found: The adapter (Realtek RTL8723B Wireless Lan 802.11n USB 2.0 Network Adapter) has driver or hardware related issues."

Since you copy the error times and look, whether something comes, that helps you.

I would first turn off the modem router briefly and then turn it back on, so it restarts.
