WiFi adapter missing from Device Manager
The WiFi adapter is probably disabled in BIOS or Device Manager, or the driver is missing. First, restart your computer completely. Sometimes this is all it takes. If that doesn't work, check Device Manager to see if the adapter is listed as disabled or unknown.
Your WiFi adapter is a small piece of hardware that picks up WiFi signals. If it's not showing in Device Manager, Windows can't see it at all. This means no WiFi. This happens when your computer got disabled by accident, the driver goes missing, or the adapter isn't getting power. A full restart fixes it sometimes, but if the adapter is disabled or unknown, you'll need to enable it or reinstall the driver.
- ✓Check if an Ethernet cable will work as a backup while you fix this
- ✓Check if your computer has a WiFi on/off switch or key combination that can be turned off
- ✓Check if Device Manager shows any unknown devices or devices with warning symbols

Skip, I just want a technicianCommon mistakes to avoid
- Not waiting long enough for the adapter to enable. It can take 10 seconds to show up
- Trying to fix BIOS settings without reading your computer manual. Different brands use different keys and menus
- Assuming the adapter is broken when it's just disabled in software
Signs you need professional help
- You've enabled the adapter and restarted, but it still won't show WiFi networks. BIOS shows WiFi disabled but you can't enable it. Device Manager shows the adapter but it still can't connect. You've tried downloading the driver but it won't install.
