Example of searching by ID:VEN_10EC&DEV_8179 -> Realtek
VEN_168C&DEV_0032 -> Atheros
After downloading the installation file, run it as administrator. Follow the instructions of the installation wizard. Once the process is complete, be sure to reboot the system so that the changes in the registry and system libraries came into force.
What to do if there is no official driver?
If the HP website doesn't have a driver for your version of Windows (e.g., Windows 11), try installing the driver for Windows 8.1 or 10 in compatibility mode. Right-click the installer -> Properties -> Compatibility -> Run for Windows 8. This often helps activate older Wi-Fi modules on newer operating systems.
Setting up power options
The Windows operating system strives to save energy, and sometimes this leads to incorrect operation of network cards. Laptop HP 250 G4 may automatically turn off the Wi-Fi adapter to save battery power, after which it will not be able to activate it correctly.

Windows Services and Network Reset
A special system service is responsible for wireless networking in Windows. If it's stopped or malfunctioning, you won't be able to turn on Wi-Fi using any buttons. Checking the service's status WlanSvc (WLAN AutoConfig Service) is a mandatory step in deep diagnostics.
To check, click Win + R, enter services.msc and press Enter. Find "WLAN AutoConfig Service" in the list. Make sure the Startup Type is set to "Automatic" and the service status is "Running." If the service is stopped, click the "Start" button.
Modern versions of Windows also feature a full network reset. This drastic but effective method removes all network adapters and reinstalls them, resetting TCP/IP settings to factory defaults.
| Parameter | Default value | Recommended value | Influence |
|---|---|---|---|
| WlanSvc startup type | Automatically | Automatically | Critical for Wi-Fi operation |
| Service status | Works | Works | Provides connection |
| DHCP service | Automatically | Automatically | Obtaining an IP address |
| DNS service | Automatically | Automatically | Domain Name Resolution |
If manually configuring services doesn't help, use the built-in troubleshooter. Go to Settings -> Network & Internet -> Status -> Network Reset. The system will warn you that a reboot will take place in 5 minutes. This will clear the DNS cache and reset the Winsock socket settings.
