How to connect to the Internet via Wi-Fi on a computer: 3 proven methods

Connecting your computer to the internet via Wi-Fi seems like a simple task—until you encounter missing drivers, hidden networks, or authentication errors. In practice, even modern PCs with Windows 11 Sometimes they refuse to recognize the router, and older laptops require manual configuration of security protocols. This article will help you understand all the nuances: from choosing an adapter to troubleshooting.

We will look at three main scenarios: connecting via the built-in Wi-Fi module, use of external USB adapter and setting bridge connections (If the internet comes via a cable, but you need to distribute it over the air). We'll pay special attention to typical errors—for example, when the network is visible but doesn't connect, or the speed drops to zero after 5 minutes of use. All instructions are relevant for Windows 10/11, macOS Ventura/Sonoma and popular distributions Linux (Ubuntu, Mint).

If your computer is not equipped with a Wi-Fi module, do not rush to buy a new one - an external adapter is 1500–2500 rubles (as of 2026) will solve the problem without any loss of speed. And desktop PC owners will find the section on choosing a PCIe card with support useful. Wi-Fi 6E.

1. Check if your computer has a Wi-Fi adapter

Before attempting to connect to the network, make sure your computer is physically capable of receiving Wi-Fi. Laptops typically have a built-in module, while desktop computers often don't, requiring a separate device.

To check if the adapter is available Windows:

1. Click Win + R, enter devmgmt.msc and press Enter.
2. IN Device Manager expand the tab Network adapters.
3. Look for lines mentioning Wireless, Wi-Fi, 802.11 or chip names (Intel AX200, Qualcomm Atheros, Realtek RTL8821CE).

If there are no such lines, your PC cannot catch Wi-Fi. macOS Checking is even easier: click on the icon Wi-Fi in the top panel (if it is not there, there is no adapter). Linux Run the following command in the terminal:

lspci | grep -i network

Modern adapters support the following standards:

• 📶 Wi-Fi 4 (802.11n) — up to 600 Mbps, becoming obsolete, but still found in budget routers.
• 🚀 Wi-Fi 5 (802.11ac) — up to 3.5 Gbps, optimal for most tasks.
• ⚡ Wi-Fi 6/6E (802.11ax) — up to 9.6 Gbps, low power consumption, less interference in apartment buildings.

2. Connecting to Wi-Fi on Windows 10 and 11

If you have an adapter but can't connect, follow these instructions. Windows 11 The interface has changed a little, but the logic remains the same.

Step 1: Open the list of networks. To do this:

• 🖱️ Click on the icon Wi-Fi in the lower right corner of the taskbar (next to the clock).
• 🔍 If there is no icon, click Win + A (notification center) and find the tile Wi-Fi.
• 🔄 If the tile is gray, click to turn it on.

Step 2: Select your network from the list and click ConnectIf there is no network:

• 🔍 Make sure your router is turned on and broadcasting the SSID (sometimes network name broadcasting is disabled in the settings).
• 📡 Check if you are too far from the router - concrete walls weaken the signal.
• 🔄 Reboot your router (unplug the power for 30 seconds).

Step 3: Enter your password. If an error appears "Unable to connect to this network":

Check the case of letters in your password (Caps Lock!)

Make sure your router isn't blocking your device by MAC address.

Try connecting from another device (phone) - if it doesn't work, the problem is with the router

Update your Wi-Fi adapter driver-->

3. Setting up Wi-Fi on macOS (Ventura, Sonoma, and later)

On MacBook And iMac Connecting to Wi-Fi is usually trouble-free, but there are some nuances. For example, after a system update, network settings are sometimes reset.

Step 1: Click on the icon Wi-Fi in the top panel (on the right). If it's not there:

• 🔧 Open System Preferences → Network.
• 🖱️ Click on the three dots at the bottom of the interface list and select Managing virtual interfaces.
• ➕ Add a new interface Wi-Fi, if it is not there.

Step 2: Select the network and enter the password. If macOS stubbornly refuses to connect:

• 🔄 Forget this network: Click on the Wi-Fi icon → Wi-Fi settings... → select a network → press "−" (delete). Then reconnect.
• 🛠️ Reset SMC (on MacBook with removable battery: turn off, remove the battery, press and hold the power button for 5 seconds).
• 📡 Check your router's Wi-Fi channel—macOS may be unstable on some channels (e.g., 12–14).

If Wi-Fi is lost after updating macOS, try creating a new one. network configuration:

1. Open System Preferences → Network.
2. Select Wi-Fi in the list on the left.
3. Click on the three dots below → Duplicate configuration.
4. Rename it (for example, to "Wi-Fi New") and apply.

4. Connecting to Wi-Fi on Linux (Ubuntu, Mint, Debian)

On Linux Connecting to Wi-Fi can be more complicated due to the variety of distributions and network managers. We'll look at two options: using a graphical interface and using a terminal.

Method 1: Graphical interface (NetworkManager)

• 🖱️ Click on the network icon in the upper right corner (next to the clock).
• 🔍 Select your network from the list.
• 🔑 Enter your password and confirm the connection.

If there is no network icon, install it NetworkManager:

sudo apt update && sudo apt install network-manager-gnome

Method 2: Terminal (if GUI doesn't work)

• 📋 View the list of available networks:

  nmcli dev wifi list

• 🔗 Connect to the network (replace SSID And password):

  nmcli dev wifi connect "SSID" password "password"

• 🔄 If it doesn't connect, restart the service:

  sudo systemctl restart NetworkManager

Common problems on Linux:

• 🚫 Driver missing for a Wi-Fi adapter (especially on newer laptops). Check the website for support for your chip. wireless.wiki.kernel.org.
• 🔌 RFKill Blocking (software-based Wi-Fi shutdown). Check the status:

  rfkill list

  If there is a block, unblock:

  sudo rfkill unblock wifi

network={
ssid="Your_network"
psk="your_password"
}

Then run:

sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
sudo dhclient wlan0

5. If your computer doesn't see Wi-Fi: diagnostics and solutions

It's common for an adapter to be present but no networks to be visible. The causes can be software-related (drivers, settings) or hardware-related (a broken antenna). Let's break this down step by step.

1. Checking drivers (Windows)

• 🔧 Open device Manager (devmgmt.msc).
• 🔍 Find your Wi-Fi adapter in the section Network adapters.
• 🔄 Right-click → Update driver → Search for drivers on this computer → Select from the list....
• 📥 If the update didn't help, download the driver from the manufacturer's website (Intel, Realtek, Qualcomm) and install manually.

2. Checking antennas (laptops)

• 📡 On most laptops, the Wi-Fi antennas are connected to the module via thin cables. If these are damaged (for example, when cleaning from dust), the connection will be lost.
• 🛠️ To check, open the back cover of the laptop and make sure the cables (usually black and white) are firmly seated in the module connectors.

3. Router problems

• 📡 Make sure that the router is in the enabled mode 802.11n/ac/ax (sometimes it is in the settings 802.11b/g, which is not seen by modern adapters).
• 🔒 Check if your router has filtering enabled MAC addresses (list of allowed devices).
• 📶 Try changing the Wi-Fi channel to 1–11 (channels 1–13 are allowed in Russia, but some devices do not support them).

netsh wlan show drivers

⚠️ Attention: If you recently updated your laptop's BIOS, Wi-Fi might be disabled in the settings. Go to the BIOS (usually by F2 or Del at boot) and check if the option is enabled Wireless LAN or WLAN.

6. How to connect a desktop PC to Wi-Fi without a built-in adapter

If your desktop computer can't connect to Wi-Fi, there are three possible solutions:

1. External USB adapter

• 🔌 The easiest way is to buy a USB adapter (starting at 800 rubles). Popular models:
• 🏆 TP-Link TL-WN823N (Wi-Fi 5, removable antenna).
• ⚡ ASUS USB-AX56 (Wi-Fi 6, speed up to 1.8 Gbps).
• 💰 Tenda U12 (budget option for basic tasks).
• ⚠️ Cons: Takes up a USB port and can slow down under heavy load (for example, when playing online games).

2. PCIe card (internal adapter)

• 🖥️ If you have a free slot PCIe x1 On the motherboard, you can install an internal card:
• 🔝 Intel Wi-Fi 6 AX200 (supports Bluetooth 5.2, speed up to 2.4 Gbps).
• 🎮 TP-Link Archer TX3000E (Wi-Fi 6, low ping for gamers).
• ✅ Pros: Doesn't take up USB space, better signal thanks to antennas.
• ❌ Cons: requires disassembling the system unit.

3. Powerline adapters (Wi-Fi alternative)

• ⚡ If the router is far away and the signal is weak, you can transmit the internet via electrical wiring:
• 🔌 Buy a set Powerline (For example, TP-Link AV1000).
• 📡 Connect one adapter to the router with a cable, and the second to a PC in another room.
• ⚠️ The speed depends on the quality of the wiring (in older houses it may be below 100 Mbps).

⚠️ Attention: When purchasing a USB adapter, pay attention to the supported standards. Cheap models are based on a chip. Realtek RTL8188 often slow down and lose connection. The best choice is adapters Intel or Qualcomm Atheros.

7. Security: How to secure your Wi-Fi connection

Connecting to the network is only half the battle. It's important to ensure your connection is secure against hacking and data leaks.

Basic router settings:

• 🔐 Change the default password for the router admin panel (usually admin/admin or admin/1234).
• 📡 Set the security type WPA3-Personal (or WPA2/WPA3 for compatibility). WEP And WPA unsafe!
• 🔄 Turn it off WPS - This protocol is vulnerable to brute force attacks.
• 📵 Hiding the SSID (disabling network name broadcasting) does not improve security—it only makes it more difficult for legitimate devices to connect.

Additional measures:

• 🛡️ Turn on guest network for friends' devices, it is isolated from your main network.
• 🔄 Update your router firmware regularly (there is a section in the admin panel Software update).
• 📊 Set up bandwidth control (QoS) to prevent some devices from clogging up the channel.

For Windows It is also recommended:

• 🔒 Disable automatic connection to open networks:

  Settings → Network & Internet → Wi-Fi → Manage known networks → Connection options → Disable "Connect automatically"

• 🛡️ Use a VPN (for example, ProtonVPN or Windscribe) in public networks.

8. Common mistakes and their solutions

Even after a successful connection, problems may arise. Let's look at the most common ones.

1. "No internet access" (there is a connection, but websites don't open)

• 🔧 Check your IP settings:

  ipconfig /all

  If the IP type is 169.254.x.x — The router isn't assigning an address. Reboot it.

• 📡 Manually enter DNS (for example, 8.8.8.8 And 8.8.4.4 from Google).

2. Low Wi-Fi speed (compared to cable)

• 📶 Check what frequency the network operates on: 2.4 GHz (longer range but lower speed) or 5 GHz (faster, but worse at passing through walls).
• 🔄 Switch your router to a free channel (use apps like WiFi Analyzer for Android).
• 🖥️ On Windows, disable TCP/IP Autoconfiguration:

  Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings → Wi-Fi Properties → Settings → Advanced → Disable "Automatic configuration"

3. Constant connection breaks

• ⚡ Check the adapter power: in Device Manager turn it off Allow power off to save power.
• 🔌 If you are using a USB adapter, try connecting it via USB hub with external power supply (Some adapters do not work reliably from a laptop port).
• 📡 Update your router firmware – software bugs often cause disconnections.

⚠️ Attention: If the problem appeared after a Windows update, try rolling back the Wi-Fi adapter driver. To do this, Device Manager Right-click on the adapter → Properties → Driver → Roll back.
