Laptop HP ProBook 4520s — This is a classic business model that remains in demand due to its reliability. However, users often encounter difficulties when trying to connect to a wireless network, as the hardware switches and software settings in this series have their own unique features. Unlike modern Ultrabooks, wireless module controls are located on a separate physical panel.
The problem of no internet connection may be due to a simple disabled button, missing drivers, or a conflict between system services. Turning on Wi-Fi This device requires a comprehensive approach: from checking the physical condition of the module to correctly installing the software. Below, we'll discuss all possible solutions to this problem.
It's important to note that the operating system may not detect the adapter if it's disabled at the BIOS level or physically damaged. Therefore, it's important to check each setup step by step, starting with a visual inspection of the case and ending with Device Manager.
Physical switch and touchpad Wireless
The first thing the owner needs to do is ProBook 4520s, is to inspect the work area above the keyboard. In this model, HP engineers implemented a touchscreen control panel for wireless connections. It's located at the top of the case, usually on the right or center, and is marked with an antenna icon.
If the indicator is blue, the module is active. Orange indicates that the wireless connection is disabled by software or hardware. Touch button The device may not respond to touch if the system is frozen or the control driver is not loaded. In this case, simply pressing the button may not produce any results.
⚠️ Attention: The touch panel is on HP ProBook 4520s The button is sensitive to static electricity. If the button stops responding, try turning off the laptop completely, disconnecting the battery and power supply, and then reassembling it after a minute.
Sometimes activation requires not just a tap, but holding your finger on the sensor for 1-2 seconds. Also, check if the function is blocked by a key combination. Some models use a combination Fn + F12 (or another key with an image of an antenna), which duplicates the function of the touch panel.
Checking the adapter status in the operating system
After checking the physical buttons, you should make sure the operating system sees the wireless device. In Windows 7, which is often installed by default on these laptops, or in newer versions, management is carried out through the Network and Sharing Center. Go to Control Panel → Network and Internet → Network and Sharing Center.
In the left part of the window, select the item Changing adapter settings. The icon should be displayed here. Wireless network connection. If it's grayed out and labeled "Disabled," right-click it and select "Enable." If the icon is completely missing, the problem lies deeper—in the drivers or hardware.
The absence of the Wi-Fi icon may also mean that the wireless network service has stopped. Click Win + R, enter services.msc and find the service WLAN AutoConfigMake sure it is running and the startup type is set to "Automatic".
- 📡 Check for the Wi-Fi icon in the tray near the clock.
- 🔌 Make sure there are no yellow exclamation marks in Device Manager.
- ⚙️ Restart the service WLAN AutoConfig through the services menu.
- 🔄 Reset network settings via command line.
It's important to note that the interface may differ in Windows 10 and 11, but the logic remains the same: the adapter must be activated in the system. If the system displays "No connections available," this often indicates the radio module is disabled.
Installing and updating wireless network drivers
The most common reason for Wi-Fi not working on HP ProBook 4520s - missing or incorrectly functioning drivers. This laptop was equipped with various modules: Atheros And Broadcom to Intel And RalinkThere is no universal driver, so it is important to determine the exact model of the device.
Open device Manager (through devmgmt.msc (or the "My Computer" context menu). Expand the "Network Adapters" branch. If you see a device with a yellow triangle or "Unknown Device," a driver is definitely required. Also check the "Other Devices" section.
To find the correct software, it's best to use the hardware ID. Right-click the unknown device → Properties → Details → Select "Hardware ID" from the list. Copy the top line and enter it into a search engine.
Where can I download drivers if I don't have internet access?
Use another computer or smartphone to download drivers from the official HP website in the Support section for the ProBook 4520s. Save the file to a flash drive and transfer it to your laptop. Alternatively, you can use driver packs, but proceed with caution.
When installing drivers, be sure to follow the manufacturer's recommended order. Chipset drivers should be installed first, followed by power management drivers, and only then the wireless adapter drivers. Reboot after each installation is mandatory.
| Module manufacturer | Typical device models | Driver Features |
|---|---|---|
| Intel | Intel Pro/Wireless 6200, 1000 | The most stable, frequently updated |
| Atheros | Atheros AR9285, AR9485 | Requires a specific software version for the button to work |
| Broadcom | Broadcom 4313, 802.11bgn | Often conflict with antivirus software |
| Ralink | Ralink RT3090 | Unstable operation in Windows 10 |
BIOS setup and power management
If software methods don't help, the wireless module may be disabled at the BIOS level. When turning on the laptop, press the F10 To enter BIOS settings, use the arrow keys to navigate.
You need to find the section System Configuration or Advanced. Look for a subsection Boot Options or Device ConfigurationThe parameter responsible for Wi-Fi may be called Wireless Button, Internal WLAN or Network Adapter. Make sure there is a value next to it. Enabled.
It's also worth checking your power management settings. In Windows Device Manager, find your Wi-Fi adapter, go to Properties, and open the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power."
⚠️ Warning: Changing BIOS settings may affect the operation of other components. Remember or take a photo of the original settings before making any changes.
After changing the BIOS settings, be sure to save by selecting Save Changes and Exit (usually a key F10). The laptop will reboot and the system will attempt to initialize the hardware again.
Diagnostics via command line
For advanced users and system administrators, tersedia offers the ability to diagnose and reset network settings via the command line. This method is effective when the Windows graphical interface is malfunctioning.
Run Command Prompt as administrator. Enter the command netsh wlan show driversIt will display information about the driver and its status. If the "Supported network types" line says "Not supported," the driver is incorrect.
netsh int ip resetnetsh winsock reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew
This sequence of commands resets the TCP/IP and Winsock stacks and renews the IP address. Be sure to restart your computer after running all commands. Reset network settings often solves problems with connecting to specific routers.

Common problems and their solutions
Owners ProBook 4520s We often encounter a specific problem: after installing Windows 10, the Wi-Fi power button stops working, even though the adapter itself is detected. This is due to the old drivers controlling the button (HP Wireless Button Driver) are incompatible with the new OS.
A possible solution is to install Windows 8.1 drivers in compatibility mode. To do this, right-click the driver installation file → Properties → Compatibility → Run in Windows 8 compatibility mode.
Another common issue is the Wi-Fi module falling out of the Mini PCIe slot. If the laptop has been subjected to shock or vibration, the connection may be broken. In this case, you'll need to disassemble the bottom case and reconnect the antennas and the module itself.
- 🛠 Check the integrity of the antenna wires inside the case.
- 💻 Try rolling back the system to a restore point.
- 🔌 Use a USB Wi-Fi adapter as a temporary solution.
- 📀 Install the original HP Support Assistant software.
If all else fails and the adapter isn't visible even in the BIOS, the wireless module itself may be faulty. In this case, the simplest and cheapest solution is to purchase an external USB Wi-Fi adapter.
