If you updated to Windows 11 version 25H2 and the WiFi toggle simply vanished from Settings > Network & Internet -- no adapter listed, no "WiFi" entry at all, just Ethernet or nothing -- you are not alone. This is one of the most widely reported networking regressions of the 25H2 rollout, and it has a specific, identifiable root cause rather than a generic "reinstall your drivers" answer.
What Is Actually Happening
The 25H2 update shipped with a broken power-transition handler inside the Microsoft Wi-Fi Direct Virtual Adapter -- the virtual network adapter Windows uses internally for Miracast wireless display and mobile hotspot features. On many laptops, this virtual adapter fails to resume correctly from a sleep/hibernate power-state transition during or shortly after the 25H2 upgrade. When it fails, Windows Network Setup Service can lose track of the physical WiFi adapter's registration entirely, which causes the entire WiFi section to disappear from Settings -- not just show as disconnected, but disappear completely.
This is distinct from a driver corruption issue (where WiFi shows as disabled or missing in Device Manager with a yellow warning icon) and distinct from a simple airplane-mode toggle problem. In this specific bug, Device Manager will often still show your physical WiFi adapter as functioning normally, while Settings shows nothing.
Step 1: Confirm the Adapter Is Physically Present
Before touching anything else, verify Windows still sees the hardware:
- Right-click the Start button and select Device Manager.
- Expand Network adapters.
- Look for your physical WiFi adapter (e.g. Intel Wi-Fi 6E AX211, Killer AX1690, Realtek RTL8852BE, MediaTek MT7921).
If it is listed with no warning icon, the hardware and base driver are fine -- this confirms you are dealing with the Settings/registration bug rather than a driver failure, and you can skip straight to Step 3.
If it shows a yellow triangle or is missing entirely, right-click it, choose Update driver > Search automatically for drivers, and if that fails, go to your laptop manufacturer's support site and download the chipset-specific WiFi driver directly (generic Windows Update drivers frequently do not fully support 25H2's new power management model on older Intel and Realtek chips).
Step 2: Remove the Broken Virtual Adapter
This is the actual fix for the missing-toggle bug, and it is safe -- it does not touch your real WiFi hardware:
- In Device Manager, click View > Show hidden devices.
- Expand Network adapters again and look for entries named Microsoft Wi-Fi Direct Virtual Adapter (there may be two, sometimes greyed out).
- Right-click each one and select Uninstall device. Do not check "delete driver software" -- just uninstall the device instance.
- Restart the PC. Windows will recreate a clean virtual adapter instance during boot, and in the vast majority of reported cases the WiFi option reappears in Settings immediately after sign-in.
If you rely on Miracast wireless display or Mobile Hotspot, test those features after the restart -- they are rebuilt automatically and should work exactly as before.
Step 3: Reset the Network Setup Service Registration
If Step 2 does not bring the WiFi toggle back, the Network Setup Service's internal adapter registry needs to be forced to re-enumerate. Open Command Prompt as Administrator and run:
netsh winsock reset
netsh int ip reset
netcfg -dnetcfg -d is the deeper reset -- it removes all networking components (including hidden filter drivers) from the registry so Windows rebuilds them from scratch on reboot. It requires a restart to take effect, and you should expect to briefly lose network profile settings (WiFi passwords may need re-entry).
After reboot, confirm the physical adapter registered correctly:
netsh wlan show interfaces
ipconfig /allYou should see your WiFi adapter listed with a state of "connected" or "disconnected" (not absent entirely).
Step 4: Check for a Stuck WiFi Group Policy or Airplane Mode Service Fault
A secondary cause seen alongside this bug: the Radio Management service can get stuck in a state that hard-disables WiFi hardware entirely, mimicking the missing-adapter symptom.
- Press Win + R, type
services.msc, press Enter. - Find WLAN AutoConfig. Right-click > Restart.
- Also restart Network Setup Service and Network Location Awareness.
If WLAN AutoConfig is set to Disabled (some third-party network managers change this), set its Startup type to Automatic and start it manually.
Step 5: Roll Back the WiFi Driver If the Bug Persists
If none of the above resolves it, the specific WiFi driver version installed during the 25H2 upgrade may itself be incompatible with the new power management stack:
- Device Manager > Network adapters > right-click your WiFi adapter > Properties.
- Go to the Driver tab.
- If Roll Back Driver is available (greyed out means no previous version is stored), click it and restart.
If rollback is unavailable, uninstall the driver entirely (check "Delete the driver software for this device"), restart, and let Windows Update reinstall a fresh copy -- or install the manufacturer's latest chipset-specific driver package rather than the generic Windows Update version.
Step 6: Full Network Reset as a Last Resort
If the toggle is still missing, use Windows' built-in full reset:
Settings > Network & Internet > Advanced network settings > Network reset > Reset now.
This removes every installed network adapter and reinstalls them from a clean state, restoring all networking components to Windows defaults. Your PC will restart automatically; you will need to re-enter WiFi passwords afterward.
Why This Bug Specifically Affects 25H2 and Not Earlier Builds
Windows 11 25H2 introduced a revised Modern Standby power model that changes how virtual network adapters negotiate their power state with the underlying Wi-Fi hardware. Earlier builds (24H2 and prior) used a looser handshake that tolerated a slow or failed response from the Wi-Fi Direct Virtual Adapter. The 25H2 power orchestration layer is stricter: if the virtual adapter does not acknowledge its resume state within the expected window, the Network List Service can mark the entire wireless adapter group as unavailable rather than just the virtual adapter. This is why the symptom presents as "WiFi missing" rather than "hotspot broken" -- the failure cascades upward into the primary adapter's visibility in Settings, even though the physical radio and driver stack are completely healthy.
This also explains why the bug is intermittent for some users and consistent for others. Laptops that frequently sleep and resume (rather than shutting down fully) are far more likely to trigger the failed power transition, which is why many affected users report the WiFi option "just disappearing one day" rather than immediately after the update finished installing.
Confirming the Diagnosis with Event Viewer
If you want to verify this is the exact bug before making changes, check Event Viewer for a fast, reliable signal:
- Press Win + X and select Event Viewer.
- Navigate to Windows Logs > System.
- Filter for Event ID 27 or Event ID 5002 from source e1dexpress, Netwtw, or NetAdapterCx, occurring shortly after a sleep/wake cycle.
Seeing repeated power-transition failures tied to a virtual adapter GUID (rather than your physical adapter's GUID) confirms this is the Wi-Fi Direct Virtual Adapter bug rather than a hardware fault.
PowerShell Alternative for Faster Diagnosis
If you prefer PowerShell over the Device Manager GUI, you can identify and remove the broken virtual adapter directly. Open Windows Terminal as Administrator and run:
Get-PnpDevice -FriendlyName "*Wi-Fi Direct Virtual Adapter*"
Get-PnpDevice -FriendlyName "*Wi-Fi Direct Virtual Adapter*" | Disable-PnpDevice -Confirm:$false
Get-PnpDevice -FriendlyName "*Wi-Fi Direct Virtual Adapter*" | Enable-PnpDevice -Confirm:$falseThis disables and re-enables the virtual adapter without a full uninstall, which resolves the issue in many cases without requiring a restart. If the WiFi toggle does not reappear within a minute, proceed to the full uninstall in Step 2 above.
Preventing a Repeat After the Fix
Once WiFi is restored, two settings reduce the odds of the bug recurring on the next sleep cycle:
- Open Device Manager, right-click your physical WiFi adapter > Properties > Power Management tab, and uncheck Allow the computer to turn off this device to save power.
- Run
powercfg /systemsleepdiagnosticsin an elevated Command Prompt to generate an HTML report of any devices flagged as blocking or delaying sleep transitions -- if your WiFi adapter appears, update its driver to the manufacturer's latest chipset-specific release rather than the generic Windows Update version, since OEM drivers generally have more mature power-state handling for the 25H2 model.
When to Escalate to a Professional
Most reports of this specific 25H2 bug resolve at Step 2 or Step 3. If you have gone through every step above and WiFi is still missing entirely, the issue may involve a corrupted OEM driver package, a BIOS-level wireless radio fault, or a deeper Windows component store corruption that needs targeted diagnosis rather than trial and error. In those cases it is faster and safer to get a technician to remote in and fix it directly rather than keep guessing. CloudHouse's Pay-Per-Ticket remote support team handles exactly this class of Windows networking failure on a single-ticket basis, with no ongoing contract required.
Frequently Asked Questions
Why did my WiFi option disappear completely after updating to Windows 11 25H2?
The most common cause is a broken power-transition handler in the Microsoft Wi-Fi Direct Virtual Adapter shipped with 25H2. When this virtual adapter fails to resume correctly, it can cause Windows to lose the registration for your real WiFi adapter in Settings, even though the hardware and driver are still functioning normally underneath.
Will uninstalling the Microsoft Wi-Fi Direct Virtual Adapter disable my real WiFi?
No. The Wi-Fi Direct Virtual Adapter only supports Miracast wireless display and Mobile Hotspot sharing. Uninstalling it is safe -- Windows automatically recreates a clean instance on restart, and your physical WiFi adapter is unaffected.
Does netcfg -d delete my saved WiFi passwords?
It can. Running netcfg -d resets all networking components including saved adapter configuration, so you should be prepared to re-enter WiFi passwords for your saved networks after the required restart.
Is this the same issue as WiFi showing 'no adapters found'?
It can look identical in Settings, but the underlying cause differs. If Device Manager shows your physical adapter as healthy, you are almost certainly dealing with the Wi-Fi Direct Virtual Adapter registration bug, not a hardware or driver failure. If Device Manager shows the adapter missing or flagged with an error, start with a driver update instead.
Should I roll back the entire 25H2 update instead of fixing WiFi individually?
Rolling back a full feature update is disruptive and only possible within Windows' 10-day rollback window, and it does not guarantee the underlying driver conflict won't recur on a later update. Fixing the specific virtual adapter and driver issue is faster, safer, and does not sacrifice the security and feature improvements in 25H2.
