How to Fix Wi-Fi That Disappeared After a Windows Update

October 15, 2026 · LuxuriousComputers Repair Marion OH

After a Windows update, your Wi-Fi is completely gone. The Wi-Fi icon in the taskbar has been replaced by a globe or ethernet icon, the Wi-Fi toggle has disappeared from the quick settings panel, and Settings shows no wireless network options. The Wi-Fi adapter may have vanished from Device Manager entirely. Your computer had working Wi-Fi before the update, and now it acts like it does not have a wireless card at all. This happens because the update removed or replaced the Wi-Fi driver with an incompatible version, disabled the wireless adapter, or corrupted the wireless service.

Check if Wi-Fi is just disabled

Software toggle

1. Click the network icon in the taskbar. In Windows 11, click the area showing Wi-Fi/Sound/Battery icons to open the quick settings panel. Look for a Wi-Fi tile. If it exists but is grayed out, click it to enable Wi-Fi
2. Open Settings, Network and Internet, Wi-Fi. If the Wi-Fi page exists, make sure the toggle at the top is On
3. If there is no Wi-Fi section at all in Settings, the adapter is either disabled, missing, or the driver is not installed

Airplane Mode

• Check if Airplane Mode was accidentally enabled. Settings, Network and Internet, Airplane Mode — make sure it is Off. Airplane Mode disables all wireless radios including Wi-Fi and Bluetooth
• Some laptops have a physical wireless switch or a keyboard shortcut (usually Fn + F2, F3, or a key with a wireless icon). Check that the physical wireless switch is in the On position

Check Device Manager for the Wi-Fi adapter

1. Open Device Manager (right-click Start, Device Manager)
2. Expand Network Adapters. Look for your Wi-Fi adapter — it typically has Wireless, Wi-Fi, WLAN, or 802.11 in the name. Common names include Intel Wi-Fi 6, Realtek Wireless, Qualcomm Atheros, Broadcom, MediaTek
3. If the adapter is listed with a yellow triangle: the driver has an error. Right-click it, select Update Driver, Search Automatically. If that does not work, right-click and select Uninstall Device, then restart the computer
4. If the adapter is listed but has a down arrow (disabled): right-click it and select Enable Device
5. If the adapter is not listed at all: click View, Show Hidden Devices. If it appears grayed out, the driver was uninstalled. Right-click and select Update Driver. If it does not appear even as hidden, click Action, Scan for Hardware Changes

Reinstall the Wi-Fi driver

From Device Manager

1. If the adapter is visible (even with an error): right-click, Uninstall Device, check Delete the Driver if that option appears
2. Restart the computer. Windows attempts to automatically install a driver on boot
3. If Windows installs a driver and Wi-Fi returns, the problem was a corrupted driver that the reinstall fixed

Download the correct driver manually

Since Wi-Fi is not working, you need another way to get the driver file onto the computer:

• Use Ethernet: If your computer has an Ethernet port, connect it to the router with a cable. Ethernet usually works even when Wi-Fi does not. Then download the driver normally
• Use another device: Download the driver on your phone or another computer, transfer it to a USB drive, and install it on the affected computer
• Where to find the driver: For laptops — go to the manufacturer's support site (Dell, HP, Lenovo, ASUS, Acer), enter your model number, and download the Wireless LAN or Wi-Fi driver. For desktops with a Wi-Fi card — check the motherboard manufacturer's site or the Wi-Fi card manufacturer's site

Roll back the driver

1. Device Manager, Network Adapters, right-click the Wi-Fi adapter, Properties, Driver tab
2. Click Roll Back Driver to revert to the pre-update driver
3. If this option is grayed out, the old driver was removed by the update and cannot be reverted from here. Use the manual download method above

Check the WLAN AutoConfig service

The WLAN AutoConfig service manages all wireless connections. If the update disabled it, Wi-Fi disappears completely:

1. Press Windows+R, type services.msc, press Enter
2. Scroll down to WLAN AutoConfig
3. Check its Status — it should say Running. Check Startup Type — it should say Automatic
4. If it is stopped: right-click, Start. If the startup type is Disabled: right-click, Properties, change Startup Type to Automatic, click Apply, then Start
5. After starting the service, the Wi-Fi option should reappear in Settings and the taskbar within seconds

Reset network components

1. Open Command Prompt as Administrator
2. Run these commands:
   • netsh winsock reset
   • netsh int ip reset
   • netsh interface set interface name="Wi-Fi" admin=enable (this re-enables the Wi-Fi interface if it was disabled at the network level)
3. Restart the computer

Use Network Reset

1. Settings, Network and Internet, Advanced Network Settings, Network Reset (Windows 11) or Settings, Network and Internet, Status, Network Reset (Windows 10)
2. Click Reset Now. This removes all network adapters and reinstalls them from scratch, resetting all network components to their default configuration
3. The computer restarts. After restart, Windows reinstalls network adapters. You will need to reconnect to Wi-Fi (enter the password again) and reconfigure VPN or proxy settings

Uninstall the Windows update

If the Wi-Fi driver situation is too corrupted to fix, removing the update is the cleanest solution:

1. Settings, Windows Update, Update History, Uninstall Updates
2. Uninstall the most recent update. Restart and check Wi-Fi
3. If you cannot reach Settings because you have no network and no desktop: boot into Windows Recovery Environment (force shutdown three times during boot), Troubleshoot, Advanced Options, Uninstall Updates
4. After the update is removed and Wi-Fi works again, pause updates for a few weeks to avoid the same update reinstalling immediately

Check BIOS settings

• Some laptop BIOS configurations include a setting to enable or disable the wireless adapter at the hardware level. A BIOS update (sometimes bundled with Windows updates) can reset this setting
• Enter the BIOS (press F2 or Del during boot), look for Wireless or WLAN settings under Advanced, Built-in Device Options, or similar. Make sure the wireless adapter is Enabled

System Restore

If no other fix works, System Restore rolls back the entire system to before the update:

1. Search for System Restore in the Start menu (or access it from Windows Recovery Environment if you cannot reach the desktop)
2. Select a restore point from before the update. System Restore reverts system files, drivers, and registry changes without touching your personal files
3. After the restore, Wi-Fi should work as it did before the update. You can then manually install the update later after downloading the correct Wi-Fi driver from the manufacturer
