Hi,
Wi-Fi was disabled during setup because either Airplane mode is on, the wireless adapter is turned off, or drivers aren’t installed yet.
I recommend:
Turn off Airplane mode Settings → Network & Internet → Airplane mode.
Enable Wi-Fi in Settings → Network & Internet → Wi-Fi.
In Device Manager, right-click your Wi-Fi adapter → Enable device install drivers if missing.
If still disabled, check BIOS to ensure the wireless adapter is enabled.
I hope this helps!
