Wi-Fi Adapter Missing in Windows? Three Kinds of Gone

The Wi-Fi icon has vanished from the taskbar, or Settings has no Wi-Fi section at all, and the machine was fine yesterday.

Before you download a driver from anywhere, work out which kind of gone you have. There are three, and they need three different answers.

I checked this machine to see what a healthy one reports, because you cannot tell what is missing until you know what should be there.

The three kinds, and they are not the same fault

Work this out first. Everything else depends on it.

⭐ Gone from Settings, present in Device Manager. The hardware is fine and something above it has switched off. This is the commonest one.

⚡ Gone from Device Manager too, but shown under hidden devices. Windows still remembers the adapter and has stopped loading it.

Documented by Microsoft on its Wi-Fi troubleshooting page: "If your wireless network adapter isn't listed in Device Manager, then Windows doesn't detect it."

⛔ Gone from hidden devices as well. Windows cannot see the hardware at all. That is a physical fault or a firmware switch.

⚠️ Ten seconds of looking saves you an evening of driver hunting. Right-click Start. Open Device Manager. Expand Network adapters.

What a working machine reports

The baseline, read here, so you have something to compare against.

Read on this PC, with nothing changed. It lists two physical network devices, both reporting OK, and not one network device in an error state.

⚡ The wireless adapter shows as Up, and the service behind it is running and set to automatic.

⭐ That is what healthy looks like. Two devices. No warnings. One adapter up, one service running.

⚠️ Check yours the same way in one line. Open Terminal and run:

Get-NetAdapter | Select-Object Name, InterfaceDescription, Status

⛔ Nothing wireless in that list at all sends you straight to the hidden devices step.

The service almost nobody checks

One line, and it explains a whole class of these.

⭐ Windows has a service called WLAN AutoConfig, and Wi-Fi does not exist without it.

⚡ On this machine it is running and set to automatic, which is the normal state.

⚠️ Read yours with this:

Get-Service WlanSvc

⛔ Stopped, or set to disabled, and your Wi-Fi will be missing from Settings no matter how healthy the hardware is. Set it back to automatic and start it.

Show hidden devices, which is not obvious

The step that finds the adapter Windows has quietly parked.

⚡ In Device Manager, open the View menu and tick Show hidden devices.

⭐ A greyed-out wireless adapter appearing there means Windows knows the hardware exists. Microsoft states the fix in one line: make sure the adapter "isn't disabled in Device Manager" and "select Enable device".

⚠️ Ours, and it is worth knowing: a device that only appears when hidden devices are shown is not broken. It is disconnected or disabled. That is a very different job from replacing anything.

⛔ Nothing there either means the machine genuinely cannot see the hardware.

The switches that turn Wi-Fi off without telling you

Three, and all three catch people out.

⭐ Aeroplane mode. Obvious once you think of it. Easy to switch on by accident with a function key.

⚡ A physical wireless switch or an Fn key with a radio symbol on it. Microsoft lists it too: "The physical Wi-Fi switch on your laptop or tablet is turned off. Make sure it's turned on."

⚠️ And a power setting. In the adapter's properties, Windows is allowed to turn it off to save power. On some machines it never turns it back on.

⛔ A fast shutdown can leave the adapter in that state. Shut down is not a full shutdown any more, so restart instead.

Only now, the driver

Last, because it is the slowest and the most often wrong.

⚡ Let Windows fetch it. Device Manager, right-click the adapter, then Update driver. Search automatically.

⭐ If that fails, Microsoft says: "Uninstall the network adapter driver, and then restart your computer. Windows will automatically install the latest driver."

⛔ Do not download a wireless driver from a search result. You have no Wi-Fi, so you would be downloading it on another machine anyway, and the safe place to get it is your laptop maker's own support page.

⚠️ And if the adapter is listed with a warning triangle, the code on its properties page names the fault. Those codes are specific and worth reading.

When the adapter is genuinely gone

Three honest endings.

⛔ Nothing in Device Manager, nothing hidden, nothing after a restart. That is hardware or firmware.

⚠️ A desktop with a plug-in card can have it reseated. A laptop with a soldered module usually cannot, not cheaply.

⭐ A USB Wi-Fi adapter costs very little and sidesteps the whole problem, which is worth knowing before anyone quotes you for a repair.

⚡ And if the adapter is there and simply weak, that is a different page. Signal strength has its own fixes.

Status: read on this machine, 27 August 2026, on Windows 11. Network device count, adapter status and the WLAN service state were all read here. ⛔ Nothing was changed and no fault was reproduced.

Why has my Wi-Fi adapter disappeared from Windows?

There are three different versions of that. It can be gone from Settings while still present in Device Manager, gone from Device Manager but visible under hidden devices, or gone entirely. Only the third is a hardware problem, and the first two are fixed without downloading anything.

What is WLAN AutoConfig and does it matter?

It is the Windows service that makes Wi-Fi work at all. If it is stopped or disabled, Wi-Fi vanishes from Settings no matter how healthy your adapter is. Run Get-Service WlanSvc in Terminal to see its state, and set it back to automatic if it is not.

How do I show hidden devices in Device Manager?

Open Device Manager, click the View menu and tick Show hidden devices. A greyed-out wireless adapter that only appears there means Windows still knows about the hardware. Enable it, or uninstall it and restart so Windows sets it up again.

Should I download a Wi-Fi driver to fix this?

Not first, and never from a search result. Let Windows search for a driver, and if that fails uninstall the adapter and restart so Windows reinstalls it. If you genuinely need to download one, get it from your laptop maker's own support page on a different device.

The Short Version

• Work out which of three kinds of missing you have before doing anything.
• Gone from Settings but present in Device Manager is the easy one.
• Check WLAN AutoConfig. Wi-Fi does not exist without that service running.
• Turn on Show hidden devices in Device Manager's View menu.
• A greyed-out adapter there is disabled, not broken.
• Aeroplane mode, an Fn key and a power setting all turn it off silently.
• Let Windows fetch the driver, or uninstall the adapter and restart.
• A cheap USB Wi-Fi adapter sidesteps a dead built-in one entirely.

Where to Next

Open Device Manager and expand Network adapters before anything else. Which of the three kinds you have decides everything after it.

Then run the two one-line commands above. They take seconds and they tell you whether the hardware and the service are both alive.

Turn on Show hidden devices while you are in there. That single menu tick finds adapters people assume are dead.

Restart rather than shutting down when you have finished. A shutdown is not a full shutdown and it can leave the adapter parked.

If yours came back after something none of this covers, name it in the comments. Wireless adapters vanish for stranger reasons than most hardware.
