How to connect a computer to Wi-Fi wirelessly: all the methods and solutions

Wireless internet has long been the standard for smartphones and laptops, but desktop computer owners often face the hassle of running cables across their entire apartment. Meanwhile, connecting a PC to Wi-Fi wirelessly is possible in 10-15 minutes—even if your motherboard doesn't support wireless networks out of the box. In this article, we'll explore all possible methods: from using USB adapters to hidden Windows features that can help boost your signal.

We'll cover not only basic instructions for beginners, but also advanced methods for those looking to optimize their connection. For example, you'll learn how to connect to a hidden network, why a computer might not "see" a router, and what settings to use. adapter drivers affect speed. And if you already have experience setting up networks, at the end of the article you'll find a comparison table of popular Wi-Fi adapters, showing their actual speeds in a home environment.

1. Checking for a built-in Wi-Fi module

Before purchasing additional hardware, make sure your computer does not come with built-in Wi-Fi adapterThis is true for many modern motherboards (especially the form factor mATX And ITX), as well as for all-in-one PCs. You can check this in two ways:

The first is a visual inspection. On the back panel of the system unit, look for antennas (thin plastic "horns" 5-10 cm long) or connectors with labels. Wi-Fi or WLANIf they are not there, proceed to the software check.

• 🔍 Via Device Manager: click Win + X → Select "Device Manager" → Expand the "Network Adapters" section. Look for devices with the words Wireless, Wi-Fi, 802.11ac or Dual Band.
• 📋 Via the command line: open CMD as administrator and enter:

  netsh wlan show drivers

  In the results, look for the line Hosted Network Support - if it is there, your adapter is theoretically capable of working with Wi-Fi.

⚠️ Attention: On some motherboards (eg. ASUS Prime or MSI MAG series) The Wi-Fi module may be disabled in the BIOS. If the adapter is not detected, enter the BIOS (button Del or F2 when booting) and check the section Advanced → Onboard Devices Configuration.

2. Selecting a Wi-Fi adapter for your PC

If there's no built-in module, you'll need an external adapter. There are three types:

1. USB adapters — the simplest and cheapest (starting at 500 rubles). They plug into any available USB port, but can become hot during prolonged use. Examples: TP-Link TL-WN725N (budget), ASUS USB-AC56 (dual-band).
2. PCIe adapters - are installed in the slot PCI Express On the motherboard. They provide better speed and stability, but require disassembling the system unit. Popular models: TP-Link Archer T6E (up to 1300 Mbps), Gigabyte GC-WB1733D-I (with Bluetooth support).
3. M.2 adapters - miniature modules for boards with a connector M.2 Key ESuitable for compact cases. Example: Intel Wireless-AC 9260.

When choosing, pay attention to:

• 📶 Wi-Fi standard: 802.11ac (up to 1300 Mbps) or new 802.11ax (Wi-Fi 6, up to 2400 Mbps). For full functionality with the router Keenetic Ultra or ASUS RT-AX88U Get an adapter with support AX.
• 🔄 Dual-band: adapters with support 2.4 GHz + 5 GHz allow you to avoid busy channels.
• 🖥️ OS compatibility: some budget models (for example, Realtek RTL8188EU) require manual installation of drivers on Linux.

⚠️ AttentionCheap chip adapters Realtek RTL8188 often lose connection under heavy load (for example, during online games). If you plan to use Wi-Fi for streaming or gaming, choose models with chips. Intel or Broadcom.

3. Connecting the USB adapter and installing drivers

The process of connecting a USB adapter is extremely simple:

Insert the adapter into a USB port (preferably 3.0 for high-speed models)|Wait for the drivers to install automatically (Windows 10/11)|If the driver is not installed, download it from the manufacturer's website|Restart your computer|Connect to Wi-Fi via the taskbar

-->

If Windows does not recognize the device:

1. Open device Manager (Win + X → Device Manager).
2. Find the adapter with an exclamation mark in the list (usually under "Other devices").
3. Right-click → "Update driver" → "Browse my computer".
4. Specify the path to the downloaded driver (usually this is a folder with the extension .inf).

For chip adapters Realtek or Mediatek may be required manual setting of the operating mode:

• 🔧 Go to "Network Connections" (Win + R → ncpa.cpl).
• Find the new wireless connection → right-click "Properties".
• Settings tab → Advanced button.
• Set the parameters:
  • Wireless Mode → 802.11ac (if supported)
  • Roaming Aggressiveness → Lowest (for a stable connection)
  • Transmit Power → Highest (if the signal is weak)

4. Connecting to Wi-Fi in Windows 10 and 11

Once the adapter is ready, all that remains is to connect to the network:

1. Click on the network icon in the lower right corner of the taskbar (next to the clock).
2. Select your network from the list of available networks. If there is no network, click "Hidden network" and enter the name (SSID) manually.
3. Enter the password (if the network is secured) and click "Connect".

If Windows gives an error "Unable to connect to the network":

• 🔄 Reboot your router (pull the plug for 30 seconds).
• 🔐 Check your password: sometimes the problem is in the case of characters or spaces.
• 📡 Change Wi-Fi channel in the router settings (for example, with Auto on 6 or 11 For 2.4 GHz).
• 🛡️ Temporarily disable the firewall (Antivirus may block the connection).

If your router supports WPS (the button on the router with the 🔄 symbol), you can connect without entering a password: press the WPS button on the router, then select "Connect using WPS" in Windows. This method only works if the adapter supports it. WPS (check its specifications).

⚠️ AttentionSome corporate networks use authentication 802.1X (For example, in universities or offices). To connect to such networks, you'll need a certificate issued by the network administrator. This protocol is not used at home.

5. Setting up Wi-Fi on Linux (Ubuntu, Mint, Debian)

Most Linux distributions detect Wi-Fi adapters automatically, but additional drivers may be required. If the network doesn't appear after connecting the adapter:

First, check if the system sees the adapter:

iwconfig

In the results, look for an interface of the type wlan0 or wlp3s0If it is not there, install the driver.

For chip adapters Realtek (For example, RTL8812AU) execute:

sudo apt update
sudo apt install realtek-rtl88xxau-dkms

To connect to the network:

1. Click on the network icon in the upper right corner.
2. Select your network and enter the password.
3. If the network is not in the list, try manually:

   sudo nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD"

6. Troubleshooting connection problems

Even after a successful connection, problems may still arise: slow speed, connection drops, or the inability to connect to certain websites. Here are the most common causes and solutions:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

If the problem persists, check:

• 📊 Channel loading: use the app Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to analyze the airwaves. If the channel is overloaded, change it in the router settings.
• 🔌 USB port powerSome adapters require additional power. Try connecting them through a powered USB hub.
• 🛠️ Power saving mode: In Windows, open Power Options → Advanced settings → find your adapter and uncheck the "Allow the computer to turn off to save power" option.

7. Alternative connection methods without an adapter

If you don't want to buy an adapter, you can use other devices as a "bridge":

• 📱 Smartphone as a modem:
  1. On Android: Settings → Hotspot & Tethering → Tethering & Hotspot.
  2. On iPhone: Settings → Tethering.
  3. Connect your phone to your PC via USB or Bluetooth.

⚠️ AttentionMany carriers block USB/Bluetooth internet tethering without a separate option in their plan. Check the terms in your personal account.

netsh wlan show profile name="NETWORK_NAME" key=clear

ping -n 50 server.address.com
