Buying a new computer is always exciting, but the first step to getting it up and running is connecting to the internet. Nowadays, a stable wireless network is essential for installing updates, drivers, and necessary software. However, users often encounter a situation where, after turning on a new device, the Wi-Fi icon is missing or the network can't be found at all.
There could be several reasons for this, ranging from a simple adapter being disabled in the BIOS to a lack of specific drivers that weren't pre-installed by the manufacturer. It's important to understand that wireless module A security card is hardware, just like a video card or sound card, and it requires the correct software to function. In this article, we'll cover every step, from physically inspecting the hardware to fine-tuning security settings.
Don't panic if you don't see a list of available networks immediately after unpacking. Even the latest Windows operating system may not have drivers for the latest networks. Wi-Fi modules, especially if your computer was built several months ago. We'll walk you through all possible scenarios to get you online as quickly and securely as possible.
Checking the presence and status of the wireless adapter
First, you need to make sure your computer has a built-in wireless module. While Wi-Fi is standard on modern laptops, the situation is different for desktop PCs. Many system units are sold without a built-in adapter, requiring a separate card or USB dongle to connect to the network.
You can check for the presence of the device through Device Manager. To do this, right-click the Start button and select the appropriate item from the menu. In the window that opens, find the "Network Adapters" section. If you see a device with the words Wireless, Wi-Fi, 802.11 or brand names like Intel, Realtek, Qualcomm Atheros, which means the module is physically present.
- 📡 If the adapter is present, but marked with a yellow exclamation mark, the problem is with the drivers.
- 🚫 If the adapter is not listed, but it is stated in the specification, it may be disabled in the BIOS.
- 💻 If the list only shows an Ethernet controller (Realtek PCIe GBE), then there is no built-in Wi-Fi.
It's also worth paying attention to the back panel of the system unit. If antennas (usually black or silver "horns") extend from it, the module is definitely installed. The absence of antennas on a desktop PC often indicates that an external adapter will be required for Wi-Fi functionality.
⚠️ Note: On some motherboards, antennas must be screwed in even for Bluetooth to work, as the modules are often combined. Without the antennas screwed in, the signal may be unstable or completely absent.
In rare cases, the module may be disabled programmatically. Check this via the command line. Win + R, enter cmd and press Enter. In the black window, enter the command:
netsh wlan show interfacesIf you receive a response stating that the interface is not found, then the system does not see the device. If the status is "Disabled," you can enable it with the command netsh interface set interface name="Wireless Network" admin=enabled (interface name may differ).
Installing and updating network card drivers
The most common problem when setting up Wi-Fi on a new computer is a lack of drivers. Windows 10 and 11 have a huge driver base, but they're not all-powerful. If your computer is equipped with the latest standard, Wi-Fi 6E or a specific chipset, standard OS tools won't be enough.
To install the drivers, you'll need a temporary internet connection. The easiest way is to connect your smartphone to your computer via a USB cable and enable "USB tethering" in your phone's settings. Once you have internet access, Windows will attempt to find and install the missing components automatically. Update Center.
If automatic installation doesn't work, you'll have to do it manually. You'll need to find out the exact model of your motherboard (for PCs) or laptop. This information can be found on the box, in the documentation, or on a sticker on the case. Then, visit the manufacturer's official website.
On the website, find the "Support" section, enter your device model, and go to the list of drivers. Select your operating system version. You need a file with ".exe" in the name. WLAN, Wireless or Wi-FiDownload it, run the installation, and restart your computer.
It's important to follow the installation order. If the manufacturer offers a chipset driver and a separate Wi-Fi driver, install the chipset first. This will ensure proper operation of the bus to which the wireless module is connected.
⚠️ Please note: Manufacturers' website interfaces change frequently. If you can't find the driver for your model, check the exact model name in your account or on the sticker underneath the device, as modifications may vary.
Setting up a wireless network connection
After the drivers are successfully installed, a Wi-Fi icon (resembling radiating waves) should appear in the system tray in the lower right corner of the screen. Clicking it will display a list of available networks. Select your network from the list. If there are multiple networks, use the SSID (Service Set Identifier) as a guide, which is usually listed on the router.
When you first connect, the system will ask if you want to make this computer visible to others. For a home network, select "Yes"; for public places (cafes, hotels), select "No." This network profile setting affects how easily other devices can discover your PC.
Next, you'll be asked to enter a password. Be careful when entering it: passwords are case-sensitive. After entering, click "Next." If the password is correct, Windows will apply the security settings and establish the connection.
- 🔒 The security type is usually detected automatically (WPA2-Personal or WPA3).
- 📶 The signal strength is displayed as a bar next to the network name.
- 🌐 The “Connected” status means successful authorization and obtaining an IP address.
Some corporate networks or older routers may require manual IP address and DNS configuration. To do this, go to Settings → Network & Internet → Wi-Fi → Configure adapter settingsRight-click your connection, select "Properties", then "Internet Protocol Version 4 (TCP/IPv4)" and enter the information provided by your network administrator.
Solving network visibility issues
Sometimes the driver is installed, the adapter is listed in Device Manager, but the network list is empty. This may indicate issues with the frequency range or power saving settings. Modern routers often operate in two bands: 2.4 GHz and 5 GHz. If your adapter is older, it may not see 5 GHz networks.
Check your adapter's power settings. Go to Device Manager, find your Wi-Fi adapter, right-click it, and select "Properties." Go to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power."
Why does the adapter turn off?
Windows can aggressively save power by cutting off power to USB ports or PCIe slots where the Wi-Fi module is located, which can lead to connection drops or the adapter disappearing.
It's also worth checking your WLAN service. Click Win + R, enter services.mscFind "WLAN AutoConfig Service" in the list. Make sure its startup type is set to "Automatic" and the service is running. If it is stopped, click "Start."
If all else fails, try resetting your network settings. In Windows 10 and 11, this can be done through the menu. Settings → Network & Internet → Advanced network settings → Network resetThe computer will restart and all network components will be reinstalled.
Using external USB adapters
If there's no built-in module or it's burned out, an external USB adapter is the solution. They come in a variety of form factors, from tiny "nano" adapters that barely protrude from the case to larger models with external antennas for signal boosting.
When choosing an adapter, pay attention to the support standards. For modern internet connectivity, it's best to choose devices that support the standard. AC (Wi-Fi 5) or AX (Wi-Fi 6)USB port speed is also important: the adapter should be connected to a USB 3.0 port (blue) to achieve maximum speeds, although it will also work on USB 2.0.
The installation process is simple: plug the adapter into the port. Windows will attempt to find the driver automatically. If that fails, use the included disc or download the driver from another device (phone or laptop) and transfer it via USB.
| Adapter type | Speed (max) | Antenna | What is it suitable for? |
|---|---|---|---|
| Nano USB | up to 150 Mbit/s | Internal | Laptops, office work |
| Standard USB | up to 433 Mbps | Built-in | Home, watching videos |
| High Gain | up to 1200 Mbps | External removable | Games, remote work |
| Wi-Fi 6 AX | up to 2400 Mbps | Two antennas | Professional gaming |
It's important to position the adapter correctly. Don't hide it behind the system unit if the reception there is poor. Use a USB extension cable to expose the adapter to an open area, especially if it's small and doesn't have an external antenna.
☑️ Check before purchasing an adapter
Optimizing and securing your Wi-Fi connection
Once your internet connection is up and running, it's time to think about security and stability. Make sure your network uses an encryption protocol. WPA3 or at least WPA2. Older protocols like WEP and WPA are vulnerable and easily cracked.
To improve speed, choose a clear channel. If you live in an apartment building, the airwaves are clogged with signals from your neighbors. Use analyzer apps on your smartphone (for example, WiFi Analyzer) to find the least congested channel and configure the router to operate in this range.
Also, don't forget to update your router's firmware. Manufacturers regularly release updates that patch security holes and improve compatibility with new devices. This can be done through the router's web interface, accessible at the address listed on the bottom of the device (usually 192.168.0.1 or 192.168.1.1).
Regularly check the list of connected devices in your router settings. If you notice an unfamiliar device, change the Wi-Fi password immediately. This will prevent unauthorized access to your network and data theft.
What should I do if my computer sees the network but doesn't connect?
A common cause is an IP address conflict or an incorrectly saved network profile. Try "Forgetting" the network in the Wi-Fi settings and reconnecting by entering the password. Clearing the DNS cache with the command also helps. ipconfig /flushdns in the command line.
Is it possible to share Wi-Fi from a computer to a phone?
Yes, Windows 10 and 11 have a "Mobile Hotspot" feature. If your PC has Wi-Fi, it can broadcast the internet connection received via a cable to other devices. This setting is located in the "Network & Internet" menu.
Does antivirus software affect Wi-Fi performance?
Third-party antiviruses and firewalls may block connections to new networks, considering them public. If other methods don't help, try temporarily disabling your antivirus's firewall to test.
Do I need to change my router settings for a new PC?
Usually no. The new computer should pick up the settings automatically. The exception is if the router is configured for MAC address filtering. In this case, the MAC address of the new device must be whitelisted in the router settings.
