Wifi intel driver is down

Windows 11 error 43 means a device has reported a problem, often due to driver corruption, outdated drivers, or a hardware malfunction.

If you tried to update drivers via the device manager, that doesn't work very reliably.

For drivers, you might find something here https://www.catalog.update.microsoft.com... or search for "[hardware ID] drivers".

You can find the hardware ID in the Device manager.

If you find a new one delete the old one b4 you try to install the new one.

If that doesn't work, the next step would be to replace the WiFi daughter board.

Ah yes, the classic ‘I deleted it, reinstalled it, cursed at my laptop, and it still won’t work’ scenario.

Here’s what I’ve learned the hard way: Windows Update is usually wrong about Wi-Fi drivers. Go straight to the manufacturer’s website and get the official driver. Uninstall, reboot, install.

Also, sometimes the Wi-Fi card just wants a nap — check Power Management settings in Device Manager. After I did that, mine came back to life like nothing happened.
