Any wifi network didn't detected

Good morning, Everyone!
It's started yesterday whan i tried to connect my phone to Wifi network at my workplace. I thought the wifi was connected.
After 30 minutes i realized that wifi network at my workplace didn't detected to my device. So, i restarted my device, and tried it. Didn't working at all.
Do anyone know what happen to my device?

Hi @okuma_24

Were other devices connecting and working OK with your work's WiFi network?

Can your phone detect other WiFi networks - maybe not connect to them, due to password requirements but detect them? Not sure if you said that it did or not.

Try using the phone as close as possible to your WiFi network router i.e. <15cm, and check if the phone detects, connects and maintains a stable WiFi connection.

Has the phone been dropped or gotten wet, prior to the problem occurring?
