- 🔘 Use a combination
Fn+ the corresponding key if the standard press does not produce a result. - 🔘 Check the LED on the key: white means the connection is active, orange means it is disconnected.
In some cases, the operating system may ignore a function key press due to the lack of specific control utilities. HP Wireless Button Driver — This is a component that ensures the correct operation of these buttons in the Windows environment. Without it, pressing a key may not produce a visible result, although the status may change in the BIOS.
⚠️ Attention: If the indicator on the key is orange and does not respond to pressing, the wireless module may be disabled in the BIOS settings or is missing from the Device Manager.
Setting up via Windows Control Center
If the hardware buttons don't respond, the next step is software control via the operating system interface. In Windows 10 and 11, the main settings are located in the taskbar. Click the globe or monitor icon in the lower right corner of the screen, next to the clock. The menu that opens should include a toggle switch. Wi-Fi.
In the deeper settings, accessible through the Settings menu, you can control additional features. Follow the path Start → Settings → Network & Internet → Wi-FiHere you'll see a list of available networks and a button to enable the module. If the slider is grayed out and inactive, the problem lies deeper—most likely with the drivers.
For users who prefer the classic interface or are using older versions of Windows, the Network and Sharing Center is available. To access it, click Win + R and enter the command ncpa.cplIn the window that opens, find the "Wireless Network" connection. If it's grayed out and labeled "Disabled," right-click it and select "Enable."
☑️ Check Windows settings
Installing and updating drivers
Lack of drivers is the most common reason why a laptop HP ProBook 635 It doesn't detect wireless networks. In Device Manager, it displays as "Unknown Device" or a device with an exclamation mark. For proper operation, you need a driver specifically for your wireless card's chipset, whether it's Realtek, Intel or Broadcom.
The manufacturer's official website provides the most compatible software versions. However, if you don't have internet access on your laptop, download the driver on another device and transfer it via USB. It's important to select the driver version that matches your system's bit depth (x64 or x86) and Windows version.
The installation process is generally standard: run the executable file and follow the wizard's instructions. After installation, be sure to restart your computer. If automatic installation doesn't help, you can try updating the driver manually through Device Manager by selecting "Update Driver" → "Browse my computer for driver software."
What to do if the driver is not installed?
If the installer returns a compatibility error, try running the file as administrator in compatibility mode for the previous version of Windows. Uninstalling the old driver via the command line may also help.
Diagnostics via Device Manager
Device Manager is the primary tool for diagnosing hardware issues. To open it, right-click the Start button and select Device Manager. Find the "Network Adapters" section. If your Wi-Fi module is listed but not working properly, it will have a yellow triangle next to it.
Double-click the device to open its properties. The error code will be listed on the General tab. For example, Code 10 or Code 43 Often indicate a hardware or driver failure. In such cases, removing the device from the list and then rebooting helps—the system will attempt to install it again.
It's also worth checking the "Power Management" tab. Make sure "Allow the computer to turn off this device to save power" is unchecked. This will prevent Windows from accidentally disabling the adapter to save battery power, which often happens on business-class laptops.
Comparison of activation methods
There are several levels of network adapter control, and it's important to understand which one is blocking your connection. Hardware disablement takes precedence over software disablement, and BIOS settings can block all other methods. Below is a table to help you determine the source of the problem.
| Management method | Priority | Typical symptom | Solution |
|---|---|---|---|
| Physical switch | Higher | The indicator lights up orange | Switch to the On position |
| BIOS / UEFI | High | The adapter is hidden in the system | Enable in the Built-in Device Options section |
| Device driver | Average | Error code in the dispatcher | Reinstalling software |
| Windows interface | Short | The slider is disabled | Enable in Settings |
As can be seen from the table, if the adapter is disabled in BIOS, no Windows actions will help. Therefore, if you have persistent problems, always start by checking your system's deep settings. Ignoring this rule will result in wasted time reinstalling drivers.
BIOS and UEFI settings
