Wi-Fi adapter displays Code 10 or Code 43 in Device Manager
The operating system hardware manager halted the wireless network card because the device firmware or driver failed to initialize.
Internal desktop parts run on harmless 12V DC voltage and cannot shock you. Simply unplug the wall power cable first, then touch the unpainted metal case frame to ground static electricity.
Common Symptoms & Tells
- Device Manager shows yellow warning icon next to Wi-Fi adapter
- Device status: 'This device cannot start. (Code 10)' or 'Windows has stopped this device (Code 43)'
- Wi-Fi toggle disappears entirely from Windows settings
Interactive Fix Checklist
0 of 5 steps completedSafety isolation and power discharge
Shut down the PC, switch off the power supply rocker switch (O), and unplug the AC power cord from the wall. Press and hold the chassis power button for 5 seconds while unplugged to drain all residual capacitor energy before touching any internal hardware.
Perform a complete static discharge (Drain flea power)
Shut down PC. Disconnect AC power cord. Hold down chassis power button for 30 seconds to drain capacitors. Reconnect power and turn on. This fixes stuck firmware state in 90% of Intel Code 10 incidents.
Install clean Intel/Realtek OEM wireless drivers
Download the standalone Wi-Fi driver from Intel or motherboard manufacturer. Uninstall existing driver with 'delete driver software' checked, reboot, and run clean installer.
Reseat M.2 Wi-Fi card inside PC/laptop
If hardware is accessible, unscrew the M.2 2230 wireless card, clean gold contacts, reconnect tiny coaxial antenna cables firmly, and screw back into place.
Disable Fast Startup
Fast Startup skips cold hardware resets. Disable 'Turn on fast startup' in Control Panel Power Options.
