How to Fix Missing Wi-Fi and Bluetooth Options in Windows & macOS

Nothing disrupts your workflow faster than opening your quick settings only to find both your Wi-Fi and Bluetooth icons completely missing. When both wireless connections vanish simultaneously, the culprit is usually a shared internal component, a system driver glitch, or an aggressive power management feature rather than two separate hardware failures.

Here is a step-by-step troubleshooting guide to get your wireless connections back online.

​The Instant Reset: Run Airplane Mode & Cold Boot

Before digging into technical settings, start with a hardware-level power reset to clear corrupted volatile memory (RAM) on your wireless card.

1. Toggle Airplane Mode: Turn Airplane Mode ON, wait 10 seconds, and turn it OFF. This forces the OS to re-initialize wireless radios.
2. Perform a Cold Shut Down:

• Do not just select Restart.
• Select Shut Down.
• Once powered off, unplug the power cable (and remove the battery if using a laptop with a removable battery).
• Hold the power button down for 30 seconds to drain residual power from the motherboard.
• Plug everything back in and boot up normally.

​Check Device Manager (Windows)

On many modern laptops, Wi-Fi and Bluetooth share a single Combo M.2 Card (e.g., Intel Wi-Fi 6 AX200/AX211 or Realtek PCIe cards). If the card loses connection or crashes, both features vanish together.
​
Step 1: Reveal Hidden Devices

1. Press Win + X and select Device Manager.
2. Click View in the top menu and check Show hidden devices.
3. Expand the Network adapters and Bluetooth sections.

Step 2: Spot the Errors
​

• Yellow Exclamation Mark: Indicates a driver crash or Code 10/43 error. Right-click the adapter, select Disable device, wait 5 seconds, and select Enable device.
• Faded/Greyed Out Icons: Means the operating system cannot physically detect the hardware.

Uncheck Power Management Savings

Windows frequently disables network cards to save power, occasionally failing to wake them back up after sleep mode.

1. In Device Manager, right-click your wireless adapter under Network adapters.
2. Select Properties and navigate to the Power Management tab.
3. Uncheck the box next to "Allow the computer to turn off this device to save power."
4. Click OK and restart your computer.

Reset Network & Bluetooth Services

If the physical hardware is fine, background system services responsible for broadcasting network and Bluetooth protocols may have stopped.

Reset System Services

1. Press Win + R, type services.msc, and hit Enter.
2. Locate Bluetooth Support Service.
3. Right-click it, select Properties, change Startup type to Automatic, and click Start if the service is stopped.
4. Locate WLAN AutoConfig, and ensure its startup type is also set to Automatic.

Perform a Windows Network Reset
​

1. Go to Settings > Network & internet > Advanced network settings.
2. Click Network reset and select Reset now.
3. This reinstalls all network adapters and restores networking settings to their factory defaults.

​Solutions for macOS Users

If you are experiencing missing Wi-Fi or Bluetooth icons on a Mac (often showing as "Wi-Fi: No Hardware Installed" or "Bluetooth: Not Available"), try these Mac-specific fixes:
​

• Reset NVRAM / PRAM (Intel Macs): Shut down your Mac, turn it on, and immediately press and hold Option + Command + P + R for about 20 seconds.
• Kill the Bluetooth Daemon via Terminal: Open Terminal and enter sudo pkill bluetoothd, then hit Enter and type your password.
• Delete Preference Files:
  1. Open Finder > Go > Go to Folder...
  2. Type /Library/Preferences/SystemConfiguration/
  3. Locate and back up (move to desktop) com.apple.bluetooth.plist and NetworkInterfaces.plist.
  4. Restart your Mac to let macOS regenerate clean preference files.

What If Nothing Works? (Hardware Checklist)

If neither Wi-Fi nor Bluetooth appears after a clean driver reinstallation and system reset, you may be facing a physical issue:
​

• Reseat the Wi-Fi/Bluetooth Card: If you use a desktop PC or an upgradeable laptop, open the chassis, remove the M.2 Wi-Fi card, clean the gold contacts with isopropyl alcohol, and firmly re-seat it.
• Use a USB Dongle Temporary Fix: If your internal card has failed, a cheap Wi-Fi/Bluetooth combo USB adapter can get you connected instantly while you arrange a repair.
