If Windows setup only shows Ethernet, the Wi‑Fi adapter is usually not being detected or its driver is missing.
Try these steps:
- Check whether the Wi‑Fi adapter appears in Device Manager
- Press Win + X > Device Manager.
- Expand Network adapters.
- If only Ethernet items appear and no wireless adapter is listed, Windows is not detecting the Wi‑Fi device.
- Install the Wi‑Fi driver
- If an Ethernet connection is available, use it to download the latest WLAN/Wi‑Fi driver from the PC manufacturer’s support page.
- If Ethernet is not available, download the driver on another device and copy it with a USB drive.
- After installing the driver, restart the PC and check whether Wi‑Fi appears.
- Run Windows Update after getting any internet connection
- Once online, run Windows Update. Missing drivers are often installed automatically.
- Check BIOS/UEFI settings
- Restart the PC and open BIOS/UEFI.
- Make sure the wireless adapter / Wireless LAN setting is enabled.
- Use Network reset if the adapter exists but Wi‑Fi still does not appear
- Go to Start > Settings > Network & internet > Advanced network settings > Network reset.
- Select Reset now > Yes.
- Warning: this removes and reinstalls network adapters and resets their settings. VPN software or virtual switches may need to be set up again.
- If Wi‑Fi disappeared after an update, reinstall the network adapter driver
- Open Device Manager.
- Expand Network adapters.
- Right-click the adapter > Uninstall device > check Attempt to remove the driver for this device > Uninstall.
- Restart the PC.
- Windows will try to reinstall the driver automatically.
- Before uninstalling, download a backup driver from the PC manufacturer if possible.
- If the wireless adapter is completely missing even after driver and BIOS checks
- The adapter may not be recognized by the system.
- If the device vanishes from Device Manager entirely, accepted guidance in similar cases indicates the hardware may be faulty and need repair or replacement.
If the immediate goal is just to finish setup, the fastest path is usually:
- connect temporarily with Ethernet, or
- use another device to download the correct WLAN driver and transfer it by USB.
