Wi Fi Adapter Fix Windows 11

Fix a missing or broken Wi‑Fi adapter in Windows 11 by matching the symptom first: 1) adapter absent, 2) adapter disabled or erroring, or 3) connected with no internet, then apply the quickest fix for that case. Use the wrong fix and you can waste time, lose internet access, or keep reinstalling drivers that do nothing. This guide gives a roughly five-minute decision tree for Device Manager, network reset, drivers, and router checks.

Wi-Fi adapter triage table

Use the symptom that matches what Windows shows right now. That keeps you from treating a hidden adapter like a driver fault, or a DNS problem like a bad card.

Safe before rebooting or reinstalling: Airplane mode off, Device Manager checks, Show hidden devices, Scan for hardware changes, Enable device, and service checks are safe first passes. Uninstalling the adapter, resetting the network stack, and Network Reset are also safe, but they can interrupt connectivity.

What the symptom means

A missing adapter usually means Windows is not detecting the wireless network interface controller at all, or it is hiding the device and the driver stack is not loading cleanly. A disabled adapter usually points to a manual toggle, a power setting, or a laptop wireless switch. Code 10 and Code 43 usually mean the adapter is present but failing to start or talk to Windows. Connected but no internet is often a DNS, IP, or router-side problem, not a dead adapter.

Likely causes, from most to least common

Most often, the fix is simple: the adapter is disabled, Airplane mode is on, or the driver is stale after an update. Less commonly, the WLAN AutoConfig service is not running, the adapter is hidden in Device Manager, or Windows network settings need a reset. Hardware failure is the last stop if all software steps fail.

Say your laptop shows Intel Wi‑Fi in Device Manager, but it has a warning symbol after a recent update. That points to a driver problem first, not a router problem. Suppose the adapter disappears after wake. That points more toward power management or service startup than a broken card.

Why is my Wi-Fi adapter missing?

If the adapter is missing from Device Manager, start with the device list itself before you reinstall anything. That is the fastest way to separate a hidden adapter from a true detection failure.

1. Open Device Manager and expand Network adapters.
2. Choose View > Show hidden devices (per CloudHouse).
3. Select Action > Scan for hardware changes.
4. Look for Intel, Realtek, Qualcomm, Broadcom, or MediaTek entries that are faded or grayed out.
5. If the adapter still does not appear, check for a laptop wireless key, function key, or hardware switch.
6. Reboot only after the adapter is not simply hidden.

TechBaked lists 17 solutions for Wi‑Fi not showing in Windows 11, and also notes that the issue can appear after installing a Windows update. That makes the device view and recent changes the best first pass.

Why is my Wi-Fi adapter disabled?

A disabled adapter is usually fixable without a reinstall. If Windows still shows the device, the problem is often a toggle state or a power setting, not a dead controller.

1. Open Settings > Network & internet > Airplane mode and turn it off.
2. Open Device Manager > Network adapters, right-click the Wi-Fi adapter, and choose Enable device.
3. If it does not stick, right-click the adapter, choose Disable device, wait 60 seconds, then choose Enable device again (per GearTrouble).
4. Open the adapter’s Properties > Power Management tab and clear any option that lets Windows turn it off to save power.
5. Restart the PC if the adapter still drops back to disabled after sign-in or wake.

Microsoft support says to turn Airplane mode off, and that applies to Windows 10 and Windows 11 (per Microsoft support). If Wi‑Fi returns after wake but vanishes again, power management is a stronger suspect than the router.

How do I fix Code 10 or Code 43?

Code 10 or Code 43 usually means the adapter is present but the driver or device communication is failing. The quickest safe path is to remove the bad instance, then let Windows reload it or replace it with the right OEM package.

1. Open Device Manager > Network adapters.
2. Right-click the Wi-Fi adapter and choose Uninstall device.
3. Check Delete the driver software for this device only if you already have the correct OEM driver ready.
4. Restart the PC, or choose Action > Scan for hardware changes after uninstalling.
5. If the error returns after a recent update, use Roll Back Driver from the adapter’s Properties > Driver tab.
6. Install the manufacturer driver package for Intel, Realtek, Qualcomm, Broadcom, or MediaTek if Windows Update keeps bringing back the same bad build.

OEM drivers often perform better than the generic Windows Update driver for laptop Wi‑Fi parts. If the adapter is in a notebook, the laptop maker’s package usually matters more than a generic one.

How do I check if WLAN AutoConfig is causing Wi-Fi problems?

WLAN AutoConfig, or wlansvc, controls wireless discovery and connection initialization. If Wi‑Fi does not start after sign-in or wake, check that service before you assume the adapter has failed.

1. Press Win + R, type services.msc, and press Enter.
2. Find WLAN AutoConfig.
3. Confirm Status is Running and Startup type is Automatic (per CloudHouse).
4. If it is stopped, open its properties and start it.
5. Restart the service, then recheck the Wi‑Fi list and connection state.

This step matters most after sleep, sign-in, or a failed wake where the adapter is visible but no wireless networks appear.

What do I do if Wi-Fi is connected but there is no internet on Windows 11?

When Windows shows a connected Wi‑Fi network but traffic fails, treat it as a network stack or DNS problem first, not an adapter outage. The adapter has linked to the access point, but name resolution or IP traffic may be broken.

1. Run Settings > System > Troubleshoot > Other troubleshooters > Network and Internet, or open it in the Get Help app if prompted (per Microsoft support).
2. Open Windows Terminal as administrator.
3. Run the command sequence below.
4. Restart the PC after the stack reset completes.
5. If the connection still shows no internet, forget the Wi‑Fi network and reconnect.

ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh winsock reset
netsh int ip reset

SolvetechToday explicitly recommends netsh winsock reset and ipconfig /flushdns. If the router looks suspect, unplug it for 60 seconds before reconnecting devices.

How do I reset my Wi-Fi adapter on Windows 11?

Use reset steps after enable/disable does not hold, or when the adapter comes back with no internet after a stack change. Start with the least disruptive option, then move to Network Reset if needed.

1. Go to Settings > Network & internet > Advanced network settings.
2. Run Network and Internet troubleshooter first.
3. If the adapter still misbehaves, open Advanced network settings > Network reset (per Microsoft support).
4. Confirm the reset and let Windows reinstall the network adapters.
5. Afterward, reconnect to Wi‑Fi and test browsing again.

GearTrouble includes a network reset when restart does not work. Use it after the lighter fixes, because it clears and reinstalls network components.

Should I use Network Reset or update the driver first?

Use the driver first when Device Manager shows Code 10, Code 43, a warning symbol, or the failure began after an update. Use Network Reset first when the adapter connects but internet traffic fails, or when enable/disable and the troubleshooter do not recover the connection.

1. If the adapter errors in Device Manager, update or roll back the driver before Network Reset.
2. If the adapter is connected but traffic fails, run the troubleshooter, then reset DNS and TCP/IP.
3. If neither step helps, use Settings > Network & internet > Advanced network settings > Network reset.
4. After a reset, reinstall the correct OEM driver if Windows comes back with a basic or unstable adapter entry.

Prevention: after a working driver is in place, keep a copy of the OEM package for your exact laptop or desktop adapter. That helps if the affected PC cannot reach the internet after a bad update.

Still not working?

If the adapter is still missing, erroring, or dropping offline after all of that, move to a broader repair path. Try a clean reinstall of the OEM Wi‑Fi driver from a second device, then copy it over by USB. If the PC cannot get online, use another computer to download the exact package from the system maker or adapter vendor.

1. Download the correct Wi‑Fi driver on another device.
2. Copy it to the affected PC and install it locally.
3. If Device Manager still shows no adapter, test in Safe Mode or use a hardware-diagnostic path from the PC maker.
4. If none of that changes the symptom, hardware failure or a router-side problem becomes more likely.

Frequently asked questions

Why is my Wi-Fi adapter not working in Windows 11 after an update?

An update can replace a working OEM driver with one that does not behave well on that hardware. Start by rolling back the driver in Device Manager, then reinstall the manufacturer package if the adapter still shows a warning symbol or Code 10/43. That is faster than a full network reset when the problem began right after patching.

How do I reinstall a Wi-Fi driver in Windows 11?

Open Device Manager > Network adapters, right-click the adapter, and choose Uninstall device. Restart the PC, or use Action > Scan for hardware changes. If Windows keeps reinstalling the same bad driver, install the OEM package for Intel, Realtek, Qualcomm, Broadcom, or MediaTek from the system maker.

Why is my Wi-Fi adapter missing from Device Manager in Windows 11?

First check View > Show hidden devices and Action > Scan for hardware changes in Device Manager. If the adapter still does not appear, check a wireless hotkey, function key, or hardware switch on the laptop. Reboot after those checks, not before, so you do not miss a hidden device state.

How do I fix a Code 10 wi-Fi adapter in Windows 11?

Uninstall the adapter from Device Manager, restart, then roll back the driver if the code appeared after an update. If the error returns, install the exact OEM driver package instead of the generic Windows Update version. Code 10 often clears when the bad driver instance is replaced cleanly.
