Wireless internet has long been the standard, but the connection Wi-Fi on your computer It still raises questions, especially for those switching from a wired connection or encountering problems after reinstalling Windows. Unlike smartphones, where everything is configured automatically, on a PC or laptop, manual driver setup, network selection, or even hardware diagnostics are sometimes required.
In this article you will find step-by-step instructions For all versions of Windows (from 7 to 11), methods for checking hardware compatibility and solving errors - from a missing Wi-Fi icon to IP address problems. And if you have a desktop PC without a built-in Wi-Fi adapterWe'll tell you which external module to choose and how to connect it. We'll start with the simplest part—checking the basic settings.
1. Check if your computer has a Wi-Fi adapter
Before setting up a connection, make sure your computer supports wireless networks. Laptops usually have a built-in Wi-Fi module, but desktop computers often require a separate purchase.
To check if the adapter is present:
- 🖥️ On Windows 10/11: click
Win + X→ select device Manager → open the tabNetwork adaptersLook for devices with names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377). - 🔍 On Windows 7/8: go to
Control Panel → System and Security → Device Manager. - 💻 On MacOS (if you have Mac): click on the icon Apple →
About This Mac → System Report → Networks. ChapterWi-Fimust contain information about the adapter.
If there are no wireless adapters in the list, then:
- 🛠️ On a laptop - maybe, The Wi-Fi module is disabled physically (there is a button or switch on the case) or in the BIOS.
- 🖥️ On a desktop PC, you'll have to buy it USB or PCIe Wi-Fi adapter (we will talk about the choice below).
⚠️ Attention: On some laptops (eg. Lenovo or HP) Wi-Fi can be disabled with a keyboard shortcutFn + F2orFn + F12Check the indicator on the case - if it is not lit, press the combination.
2. Enabling Wi-Fi in Windows: Step-by-Step Instructions
If you have an adapter but can't connect to the internet, first check whether Wi-Fi is enabled in your operating system. The steps vary depending on your Windows version.
Windows 11
1. Click on the icon networks in the lower right corner of the taskbar (next to the clock).
2. In the menu that opens, find the block Wi-Fi and move the slider to the right if it is gray.
3. Select your network from the list and enter the password.
Windows 10
1. Click on the icon networks in the tray → Wi-Fi.
2. If the button Wi-Fi inactive, click Network parameters → Wi-Fi → turn on the slider.
3. Return to the list of networks and connect to the one you need.
Windows 7/8
1. Open Control Panel → Network and Sharing Center.
2. In the left menu, select Changing adapter settings.
3. Find Wireless network connection and right-click → Turn on (if disabled).
If Wi-Fi still doesn't work after these steps, the problem may be with the router drivers or settings. More on that in the following sections.
Is Wi-Fi enabled on the router (WLAN indicator is on)?
Is the adapter detected in Device Manager?
Is Wi-Fi enabled in Windows settings?
The network password is entered correctly (case sensitive!)-->
3. Installing and updating Wi-Fi drivers
A common cause of connection problems is missing or outdated drivers for the network adapter. Even if Windows automatically installed the driver, it may not work correctly.
How to update the driver manually:
- Open
device Manager(as in the previous section). - Expand the tab
Network adapters, find your Wi-Fi module (for example, Realtek RTL8821CE or Broadcom 802.11ac). - Right click →
Update driver→Automatic search. - If Windows does not find an update, download the driver from the website of the laptop or adapter manufacturer (for example, intel.ru For Intel Wi-Fi or realtek.com For Realtek).
For your convenience, here is a table with links to the official pages of popular brands (open in a browser):
| Adapter manufacturer | Support page |
|---|---|
| Intel | downloadcenter.intel.com |
| Realtek | www.realtek.com/en/downloads |
| Broadcom | www.broadcom.com/support |
| Qualcomm Atheros | www.qualcomm.com/products/wi-fi |
| TP-Link (USB adapters) | www.tp-link.com/ru/support/download |
⚠️ Attention: If after updating the driver Wi-Fi stops working completely, roll back to the previous version:Device ManagerselectProperties → Driver → Roll Back DriverThis will only work if the driver was already installed before the update.
4. Connecting Wi-Fi to a desktop PC (without a built-in adapter)
If you have desktop computer Without a Wi-Fi module, you'll need to purchase an external device. There are three options:
- 🔌 USB Wi-Fi adapter — the simplest and cheapest method. It plugs into any USB port and doesn't require opening the system unit. Examples: TP-Link TL-WN725N, ASUS USB-AC56.
- 🖥️ PCIe Wi-Fi card - installed in a slot
PCI Expresson the motherboard. Suitable for gaming PCs where high speed is required (for example, Intel Wi-Fi 6 AX200). - 📶 M.2 Wi-Fi + Bluetooth module — a compact solution for mini-PCs or systems with a free slot
M.2 Key E.
Which adapter should I choose?
| Criterion | USB adapter | PCIe card | M.2 module |
|---|---|---|---|
| Speed | Up to 300–1200 Mbps | Up to 2400–5000 Mbps (Wi-Fi 6) | Up to 2400 Mbps |
| Convenience | ⭐⭐⭐⭐⭐ | ⭐⭐ (requires opening the case) | ⭐⭐⭐ (requires M.2 slot) |
| Price | From 500 ₽ | From 2000 ₽ | From 1500 ₽ |
| Bluetooth support | A number of models (for example, TP-Link Archer T3U Plus) | Often included in a set | Almost always |
After purchasing the adapter:
- Connect it to your PC (USB or slot-in).
- Install the drivers from the disk (if included) or download them from the manufacturer's website.
- Restart your computer and connect to the network as described in Section 2.
How to check if a PCIe adapter is compatible with a motherboard?
Open the documentation for your motherboard (look for the model on the manufacturer's website, for example, ASUS or Gigabyte) and check:
1. Availability of a free slot PCIe x1 or PCIe x4.
2. Support of the standard M.2 Key E (if you choose M.2 module).
3. On some boards you may need to disable the integrated network card in the BIOS (Onboard LAN Controller → Disabled).
5. Troubleshooting Wi-Fi connection issues
If Wi-Fi is turned on and the drivers are installed, but the internet is not working, check the following:
🔴 No networks available
- 📡 Make sure that the router is turned on and broadcasts the network (the indicator is on)
Wi-FiorWLAN). - 🔄 Reboot your router (unplug the power cord for 30 seconds).
- 🛠️ Check your router settings: go to the web interface (usually
192.168.0.1or192.168.1.1) and make sure the option is enabledEnable WirelessorBroadcast SSID.
🔴 There is a connection, but there is no internet access
- 🌐 Check if the internet works on other devices (phone, tablet). If not, the problem is with your provider.
- 🔧 Run diagnostics in Windows: click on the network icon →
Troubleshooting. - 📝 Check your settings
IPAndDNS:- Open
Control Panel → Network and Sharing Center → Change adapter settings. - Right click on Wireless connection →
Properties. - Select

- Open
🔴 The connection keeps dropping out
- 📶 Check the signal strength: if it is weak (1-2 bars), try moving the router closer or using signal amplifier.
- 🔄 Change the Wi-Fi channel in the router settings (for example, from
Autoon6or11). - 🛡️ Update your router firmware (instructions are usually available on the manufacturer's website, for example, TP-Link or ASUS).
⚠️ Attention: If after connecting to Wi-Fi Windows writes"Unidentified network" without internet access, and the Internet works on other devices, try entering it manuallyDNSfrom Google:8.8.8.8And8.8.4.4(in settingsIPv4, as described above).
6. Setting up Wi-Fi on a Linux computer (Ubuntu, Mint)
If you use Linux, the process of connecting to Wi-Fi is slightly different. Let's look at an example. Ubuntu 22.04 LTS:
1. Click on the network icon in the upper right corner → select your network → enter the password.
2. If the network is not listed, check if Wi-Fi is enabled:
sudo rfkill unblock wifi
3. Install proprietary drivers (if the adapter is not recognized):
sudo ubuntu-drivers autoinstall
sudo reboot
4. For manual configuration, use the utility nmcli:
nmcli dev wifi list # Show available networks
nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD"
If Wi-Fi still doesn't work after these steps, check the command output:
dmesg | grep -i wifi
It will show errors related to drivers or hardware.
7. Security: How to protect your Wi-Fi connection
Once you have successfully connected, be sure to check your security settings to avoid network hacking or data leakage:
- 🔒 Use WPA3 (or at least WPA2-PSK) instead of the outdated one
WEPorWPAThis is configured in the router's web interface (192.168.0.1or192.168.1.1). - 🔑 Complex password: at least 12 characters with numbers, capital letters and special characters (e.g.
K7#pL9!mQ2$v). - 📡 Turn off
WPS- this function is easy to hack (find it in the router settings)WPS → Disable). - 👤 Change the default login/password for your router (
admin/admin) to unique ones. - 🌐 Turn on guest network For friends, it is isolated from your main network.
- Log into your router's web interface.
- Find the section
DHCP Clients List,Connected DevicesorLocal area network. - Check the list of devices. Unknown
MAC addresses- a sign of a break-in.
We also recommend periodically checking who is connected to your Wi-Fi. To do this:
FAQ: Frequently asked questions about connecting Wi-Fi to your PC
🔹 Why can't my computer see Wi-Fi networks, but my phone can?
There are several reasons:
- On the computer the Wi-Fi adapter is disabled (physically or in BIOS).
- The driver is not installed or outdated (check in Device Manager).
- The router is operating in the mode
802.11ac(5 GHz), and your adapter only supports802.11n(2.4 GHz). Try enabling support in your router settings.2.4 GHz. - It's disabled in the router.
Broadcast SSID(hidden network). To connect to such a network, enter its name and password manually in Windows settings.
🔹 How to connect to a hidden Wi-Fi network?
1. Open Settings → Network and Internet → Wi-Fi.
2. Click Manage known networks → Add new network.
3. Enter the network name (SSID), security type (WPA2-Personal) and password.
4. Save and connect.
If you don't know SSID, look it up in your router settings or on the sticker on the device itself.
🔹 Is it possible to connect to Wi-Fi without a password?
Technically yes, but that's unsafeIf your router is configured for an open network (no password), you'll be able to connect, but:
- Your traffic will be unencrypted (risk of data interception).
- Your neighbors will be able to connect to your network, which will slow down the speed.
- Your provider may block such networks (especially in public places).
It's better to ask the router owner for the password or set up a guest network with limited access.
🔹 Why is Wi-Fi slow on my computer but fast on my phone?
Possible causes and solutions:
- Outdated adapter: if your Wi-Fi module only supports
802.11n(up to 300 Mbps), and the router operates in the mode802.11ac(up to 1300 Mbps), the speed will be limited. The solution is to buy a modern adapter (for example, Intel AX200). - Interference on the channel: If the router has automatically selected a congested channel, change it manually (for example, with
6on11in the settings2.4 GHz). - Drivers: Update your Wi-Fi adapter driver (see Section 3).
- Background programs: check if torrents, cloud services or Windows updates are loading the network (open
Task Manager → Network Connections).
🔹 How do I share my computer's Wi-Fi with other devices?
If you have wired Internet, you can turn your PC into an access point:
- Open
Command lineas administrator (Win + X → Command Prompt (Administrator)). - Enter the command to create the network:
netsh wlan set hostednetwork mode=allow ssid=MyWiFi key=12345678 keyUsage=persistent(replace
MyWiFiAnd12345678to your network name and password). - Start the distribution:
netsh wlan start hostednetwork - Allow sharing: open
Control Panel → Network and Sharing Center → Change adapter settings, right click on Ethernet (wired connection) →Properties → Access→ check the boxAllow other network users to share your Internet connectionand select the created network (Local Area Connection* X).
To stop seeding, run:
netsh wlan stop hostednetwork
For continuous distribution, use programs like Virtual Router Plus or Connectify.
