Read the symptom before changing settings
| What you observe | Where to focus |
|---|---|
| Wi-Fi absent but Ethernet works | The wireless adapter, service or driver is the likely layer. |
| Adapter appears disabled | Enable it and restart before changing drivers. |
| Adapter has a warning icon | Read the Device status code and use the manufacturer’s driver. |
| Adapter is absent even under hidden devices | Check BIOS/UEFI, a hardware switch and the PC maker’s diagnostics. |
Check controls that can hide wireless networking
Open Quick Settings with Windows + A and make sure Airplane mode is off. Some laptops also have a physical wireless switch or function-key combination. Use the manufacturer’s manual because the key differs by model.
Open Settings > Network & internet > Advanced network settings. If Wi-Fi is listed as disabled, select Enable and restart Windows.
1Inspect the adapter in Device Manager
- Open Device Manager and expand Network adapters.
- Look for a device whose name includes Wireless, Wi-Fi, WLAN or an 802.11 standard.
- Choose View > Show hidden devices only as a diagnostic check. A grey old entry does not prove that the current hardware is working.
2Read the device status before reinstalling
- Open the adapter’s Properties and read Device status.
- A code can indicate a driver, resource or hardware problem. Record it before making changes.
- If the device is disabled, enable it and restart.
Restore the supported service and driver
Press Windows + R, enter services.msc and find WLAN AutoConfig. Wi-Fi discovery depends on this service. It should normally be running with Automatic startup unless an organisation intentionally manages wireless access.
Download the correct Windows 11 wireless driver from the PC manufacturer using Ethernet or another device. Match the exact model and, when the manufacturer lists several adapters, identify the installed hardware before choosing a package.
1Try update or rollback first
- In the adapter’s Properties, check the Driver tab.
- If the Wi-Fi option vanished after an update and Roll Back Driver is available, use it and restart.
- Otherwise install the PC maker’s current Windows 11 package.
2Reinstall only with a driver backup
- Have the correct driver installer available locally.
- Uninstall the wireless adapter in Device Manager and restart; Windows may reinstall it automatically.
- If it does not return, run the saved manufacturer installer. Do not use anonymous driver-download sites.
When the adapter is completely absent
Shut down fully, disconnect external docks and start the PC again. For removable USB Wi-Fi adapters, test another port and another computer. For an internal adapter, run the manufacturer’s built-in hardware diagnostics.
If firmware settings expose wireless control, confirm it is enabled, but do not update firmware or reset security keys casually. A device that is absent from Windows and the manufacturer’s diagnostic environment may need hardware service.
Frequently asked questions
Why did the Wi-Fi button disappear after an update?
A wireless driver may have failed, rolled forward incorrectly or left the adapter disabled. Check Device Manager and use the PC maker’s supported driver or rollback option.
Can I fix missing Wi-Fi with Network reset?
It may help when the adapter exists but its configuration is broken. It is unlikely to help when the wireless device is absent from Device Manager or disabled in firmware.
Does a missing Wi-Fi option mean the adapter is dead?
Not necessarily. Airplane mode, a disabled adapter, stopped WLAN AutoConfig service or damaged driver can cause the same symptom. Hardware becomes more likely only after those checks fail.
