Wireless Internet has long been the standard for most devices, but sometimes users encounter problems: Wi-Fi on my computer won't turn on, even though the router is working properly. The causes could be various, ranging from accidentally pressing a key to a disabled adapter in the system. This article will help you figure it out. where exactly is Wi-Fi turned on? On different types of computers, what hardware and software activation methods exist, and what to do if standard methods don't work.
We will consider all possible scenarios: from the obvious (a button on the laptop case) to hidden (settings in BIOS/UEFI or device manager). We will pay special attention Windows 10 and 11, since these OS versions have the most up-to-date interfaces. If you are using Linux or macOS, the principles will be similar, but the menu paths may differ - we will also mention this.
Before you begin tweaking settings, make sure the problem is with your computer and not your router. Try connecting to the network from another device (e.g., a smartphone). If the internet works, the issue is with your PC settings. If not, check the settings. section on router diagnostics at the end of the article.
1. Hardware methods for turning on Wi-Fi: buttons and switches
Many laptops and some desktop PCs with Wi-Fi adapters have physical switches or key combinations for turning the wireless network on/off. These are easy to miss, especially if you recently purchased a device or reinstalled the system.
Where to look:
- 🔘 Separate button on the case (usually on the side panel or next to the keyboard). On some models Lenovo, HP or Acer It could be a small slider.
- 🔑 Key combination (usually
Fn + F2,Fn + F5orFn + F12). The exact combination depends on the manufacturer - look for it on the keysF1-F12antenna icon (📶). - 🖥️ Switch on the back panel (Applicable to some desktop PCs with built-in Wi-Fi, such as Apple iMac or monoblocks ASUS).
If you're unsure whether your device has a hardware switch, check the documentation or search for model information. For example, on laptops Dell Latitude a combination is often used Fn + PrtScn, and on MSI - a separate button with backlight.
⚠️ Attention: On some devices (especially business class ones), a hardware switch blocks Wi-Fi at theBIOSIf the button doesn't work, check your settings.UEFI— more about this in section 4.
2. Turn on Wi-Fi via the Windows taskbar
The fastest way to activate Wi-Fi is to use notification center in Windows. This method works on Windows 10 And Windows 11, as well as on most assemblies Linux with a graphical interface (for example, Ubuntu or Mint).
Step-by-step instructions for Windows:
- Click on the icon networks (📶 or 🌐) in the lower right corner of the taskbar (next to the clock).
- If Wi-Fi is disabled, you will see a gray icon that says
No internet connectionorWi-Fi: off. - Click on the tile Wi-Fi (in Windows 11 it may be called
Wireless network). - Select the desired network from the list and enter the password (if required).
If the network icon is not on the taskbar:
- 🔍 It might be hidden. Click the arrow.
^next to the notification area to expand hidden icons. - 🔧 If there is no icon at all, check your taskbar settings:
Settings → Personalization → Taskbar → Notification area.
☑️ Check the taskbar
On macOS The process is similar: click the Wi-Fi icon in the top bar (📶) and select a network. If you don't see the icon, check your settings in System Preferences → Network.
3. Turn on Wi-Fi via Windows Settings
If hardware switches don't help and the Wi-Fi icon is missing from the taskbar, try turning on the adapter via system settingsThis method is universal and works even if the drivers are not installed correctly (although in this case, additional configuration may be required).
Instructions for Windows 10/11:
- Open
Parameters(keyboard shortcutWin + I). - Go to the section
Network and Internet→Wi-Fi. - Move the slider Wi-Fi in position
On. - Click
Show available networksand choose yours.
If the slider is gray and inactive:
- 🛠️ Check if the Wi-Fi adapter driver is installed (more on this in section 5).
- ⚙️ The adapter may be disabled in
Device Manager. - 🔒 On some corporate PCs, access to Wi-Fi may be blocked by security policies (this applies to domain networks).
On Linux The path may differ depending on the distribution. For example, in Ubuntu you need to go to Settings → Wi-Fi and turn on the wireless network. In some builds (for example, Arch Linux) manual configuration may be required via nmcli or iwconfig.
4. Checking BIOS/UEFI settings
It's rare, but there are cases when Wi-Fi is disabled at the level BIOS/UEFIThis can happen after a factory reset, a firmware update, or if someone intentionally disconnected the adapter. Checking this is easy, but it will require a computer restart.
How to enter BIOS/UEFI:
- 🖥️ Laptops: usually a key
F2,Del,EscorF12(Depending on the manufacturer). Press it immediately after turning on the PC, before the Windows logo appears. - 💻 Desktop PCs: more often
DelorF2.
Inside BIOS search sections:
Advanced → WirelessorOnboard Devices.Configuration → Network.Security → I/O Port Access.
The parameter can be named differently:
| Manufacturer | Possible option name | Recommended value |
|---|---|---|
| Lenovo, Dell | Wireless LAN, WLAN Radio |
Enabled |
| HP, Acer | Wi-Fi Adapter, Wireless Device |
On |
| ASUS, MSI | Onboard WLAN, WiFi Controller |
Enabled |
| Apple (Hackintosh) | Wi-Fi/Bluetooth |
Auto or Enabled |
After changing the settings Be sure to save their (usually a key F10) and reboot your computer. If there is no option at all, then your Wi-Fi adapter is not managed via BIOS, and the problem lies elsewhere.
⚠️ Attention: On some motherboards (eg. Gigabyte B550) The Wi-Fi option may be hidden in the advanced settings. If you can't find it, check the sectionChipsetorPeripherals.
5. Device Manager: Checking and activating the adapter
If Wi-Fi does not turn on using any of the listed methods, the adapter may be disabled in the system or the drivers for it are not installed. You can check this through device Manager.
How to open:
- Click
Win + Xand selectdevice Manager. - Or type in Windows search
devmgmt.mscand pressEnter.
Next steps:
- Expand the branch
Network adapters. - Find the device with the names
Wireless,Wi-Fi,802.11or adapter model (for example, Intel AX200, Qualcomm Atheros, Realtek RTL8821CE). - If there is a down arrow (↓) next to the adapter, right-click on it and select
Activate the device. - If the adapter is marked with an exclamation mark (!), update the driver (right-click →
Update driver).
Critical information: If your Wi-Fi adapter isn't listed at all, it may be disabled in the BIOS, physically damaged, or not recognized by the system (for example, after a Windows update). In this case, check the adapter's connectors (on laptops, it's often connected via a port). M.2 or mPCIe) or try connecting an external USB adapter.
For Linux The adapter is checked using the command:
lspci | grep -i network
iwconfig
If the adapter is not displayed, you may need to install proprietary drivers (for example, for chips Broadcom).
6. Driver Problems: Diagnosis and Solution
One of the most common sources of Wi-Fi problems is incorrect or outdated driversThis is especially true after major Windows updates (for example, switching from Windows 10 on Windows 11) or after a clean installation of the system.
Signs of driver problems:
- 🔴 The Wi-Fi adapter is displayed in
Device Managerwith an exclamation mark. - 🔄 Networks are detected, but the connection keeps dropping.
- 🖥️ The list of networks is empty, although the router is working.
- 🔍 In
Propertiesadapter specifiedThe device is not working properly (code 10).
How to update the driver:
- Open
device Manager(see section 5). - Find your Wi-Fi adapter, right click and select
Update driver. - Select
Automatic searchIf Windows doesn't find updates, download the driver from the manufacturer's website:
| Adapter manufacturer | Support link (download section) | Example of a model |
|---|---|---|
| Intel | downloadcenter.intel.com |
AX200, AX210, 7265 |
| Qualcomm Atheros | qualcomm.com/support |
QCA6174, QCA9377 |
| Realtek | realtek.com/en/downloads |
RTL8821CE, RTL8188EE |
| Broadcom | broadcom.com/support |
BCM4352, BCM4360 |
If automatic update does not help:
- 🔧 Uninstall the current driver (right click →
Remove device), then restart your PC. Windows will try to install the driver again. - 📥 Download the driver from the manufacturer's website laptop (For example, Lenovo, HP), not the adapter - sometimes they are better optimized.
- 🛠️ For Linux install the package
firmware-iwlwifi(For Intel) orbroadcom-sta-dkms(For Broadcom).
What to do if the driver is not installed?
If Windows gives an error "The driver is not designed for this platform.", try downloading the 64-bit (x64) or 32-bit (x86) version depending on your system. Also, check if your antivirus software is blocking the installation (e.g. Kaspersky or Avast Sometimes drivers are removed as "suspicious files").
7. Diagnosing router problems
If everything is configured correctly on your computer, but Wi-Fi still isn't working, the problem may be with your router. Here's what to check:
Basic steps:
- 🔌 Restart your router (unplug it from the power outlet for 30 seconds and plug it back in).
- 📡 Make sure the Wi-Fi indicator on your router (usually marked with a 📶 icon) is on.
- 🔒 Check if your network password has changed (perhaps someone reset the router settings).
- 📱 Try connecting to the network from another device (smartphone, tablet).
Advanced settings:
- 🛡️ Check if it is enabled on your router
MAC filter(it may block your computer). - 🔄 Make sure your router is in wireless mode
802.11n/ac/ax(and not only802.11b/g), otherwise modern adapters may not see the network. - 📶 If the signal is weak, try changing the Wi-Fi channel in the router settings (for example, from
caron6or11).
To access your router settings:
- Find out its IP address (usually
192.168.0.1,192.168.1.1or10.0.0.1). - Enter the address in your browser and log in (default logins:
admin/admin,admin/blank password). - Go to the section
WirelessorWi-Fiand check the settings.
⚠️ Attention: If you're unsure of your router settings, don't change them randomly—this could result in internet loss. It's best to consult your device's manual or your internet provider.
8. Alternative ways to connect to Wi-Fi
If the standard methods don't work, there are several workarounds:
1. USB Wi-Fi adapter
If the built-in Wi-Fi module does not work, you can buy an external adapter (for example, TP-Link TL-WN725N or ASUS USB-AC53 Nano). It plugs into a USB port and is usually automatically recognized by the system. Pros:
- 💰 Low price (from 500 rubles).
- 🔌 Does not require opening the laptop/PC.
- 📶 Often supports more modern standards (eg.
Wi-Fi 6).
2. Sharing the Internet from a smartphone
A temporary solution if you urgently need to get online:
- On Android:
Settings → Network & Internet → Hotspot & Tethering → Wi-Fi Hotspot. - On iPhone:
Settings → Tethering. - Connect your computer to the created network.
3. Ethernet via Powerline adapter
If Wi-Fi is fundamentally not working, but there is access to an outlet, you can use Powerline adapters (For example, TP-Link AV600). They transmit the internet signal through electrical wiring. The downside is the high price (from 2,000 rubles per set).
4. Connection via cable
If the router is nearby, the easiest way to connect is through Ethernet-cable. The speed will be more stable, and the delays (ping) will be lower. Cable categories Cat 5e or Cat 6 provides speeds up to 1–10 Gbps.
FAQ: Frequently asked questions about turning on Wi-Fi on your computer
