Wireless WiFi network?

The exact model number of your system is needed in order to help diagnose the issue. In general though are you sure that you have a Wifi card installed and if so that function may be disabled in the BIOS.

In addition to what @JOcean asked, also Include version of Windows too.

1. If you see ^ symbol in Notification area, click it to see if Network icon is just hidden
2. If not hidden, right-click empty area of taskbar and select Task Bar Settings
3. Scroll down to Notification Area
4. Click Select which icons can appear in taskbar
5. On new screen, make sure Network has permission to appear
6. You may have to reboot before that icon appears, if you had to give it permission

• Press Win + I to open Settings.
• Go to Update & Security > Troubleshoot > Additional troubleshooters.
• Select Network Adapter and run the troubleshooter.

How are you using WiFi - USB dongle or PCIe card?  Are you signed in to your network?

Suggests a possible bot post, so don't waste electrons and your time here...
