Wi-Fi adapter missing on Windows

When the Wi-Fi toggle disappears entirely, Windows no longer sees the wireless adapter - usually a driver failure, a disabled device or (on laptops) a radio switched off at the hardware level. Work through the checks below in order.

Why this happens

  • The wireless adapter's driver failed to load or was removed during an update.
  • The adapter is disabled in Device Manager or by a laptop function key (Fn + radio key).
  • Airplane mode is stuck on.
  • Power management turned the adapter off and it didn't wake.
  • The adapter died or is loose (desktop USB/PCIe adapters).

Quick checks first

1Airplane mode and the physical switch

Check Settings → Network & internet: airplane mode off. On laptops also try the Fn key with the radio/airplane icon - some models disable the radio below the OS level.

2Is the adapter in Device Manager?

Win+X → Device Manager → Network adapters. Look for a device with Wireless/Wi-Fi/WLAN/802.11 in its name. If it's missing, check “Other devices” for an Unknown device - that's likely your adapter without a driver. View → Show hidden devices helps too.

3Network troubleshooter and adapter reset

Settings → Network & internet → Advanced network settings → Network reset. This reinstalls network adapters and resets configuration (you'll need to re-enter Wi-Fi passwords).

4Did it break after a Windows Update?

Settings → Windows Update → Update history. A driver update installed right before Wi-Fi vanished is the prime suspect - the rollback fix below targets exactly this.

If Wi-Fi is still gone after these checks, the next step is to identify the exact wireless adapter and check its driver - the Hardware ID reveals which chip is inside, even if the adapter shows no name.

Drivers most often behind this problem

Fixing it manually

Re-enable and power-cycle the adapter

  1. In Device Manager, right-click the wireless adapter → Enable device (if disabled).
  2. Properties → Power Management tab → uncheck “Allow the computer to turn off this device to save power”.
  3. Reboot the PC completely (Shut down, not Sleep).

Roll back or reinstall the Wi-Fi driver

  1. Device Manager → adapter Properties → Driver tab → Roll Back Driver (if active) - best option when Wi-Fi vanished after an update.
  2. If rollback is unavailable: Details → Hardware Ids, copy the PCI\VEN_… value.
  3. Find the exact driver in our database by that ID, download it from the official source (on another device or via Ethernet) and install it.

Know the exact device model?

Search the Wi-Fi driver database by adapter name, computer model or Hardware ID. Review matching Windows versions and available driver releases.

Wireless adapters are internal - the laptop model alone often isn't enough, because vendors ship the same model with different Wi-Fi chips (Intel, Realtek, Qualcomm, MediaTek). The Hardware ID (PCI\VEN_8086… for Intel, PCI\VEN_10EC… for Realtek) identifies the actual chip.

Try for example: Intel Wi-Fi 6 AX201 · read the Hardware ID guide · or browse the driver category

Frequently asked questions

▸Wi-Fi disappeared exactly after a Windows update - coincidence?

Not necessarily. Updates can replace the wireless driver with an incompatible version. Driver rollback (Device Manager → Driver → Roll Back) is the first thing to try.

▸Do I have to figure out which Wi-Fi chip I have myself?

No - the Hardware ID answers it for you. Even when the adapter shows as an unknown device, Device Manager → Properties → Details → Hardware Ids reveals a code that identifies the exact chip. Search that code in the database and the matching package (Intel, Realtek or MediaTek) appears - no guessing required.
