How to connect Wi-Fi to your computer: a step-by-step guide with photos and tips

Without a stable Wi-Fi connection, a modern computer loses half its functionality: no access to cloud services, online gaming, 4K video streaming, or remote work. But what if your PC or laptop can't see wireless networks and there's no way to run a cable? In this article, we'll look into the matter. all Wi-Fi connection methods — from basic setup of the built-in adapter to using external USB modules and even a smartphone as an access point.

We won't limit ourselves to standard tips like "click on the network icon." Instead, you'll get detailed instructions taking into account various scenarios: missing drivers, hidden networks, router problems, or specific Windows 11 settings. And if something goes wrong, there's a section at the end of the article with common mistakes and their solutions that save hours of googling.

Before you start, check two things: whether the Internet is working on other devices (for example, on a phone) and whether the Wi-Fi distribution mode is enabled on the router (the indicator WLAN or Wi-Fi (It should be green/blue.) If the network is there, but the computer doesn't detect it, the problem is with the computer. Let's move on.

1. Checking Wi-Fi hardware support on your computer

Not all desktop PCs and even some laptops come with a built-in Wi-Fi adapterTo avoid wasting time configuring something that doesn't physically exist, first make sure the module is present.

Laptops and all-in-one PCs usually have a wireless adapter built in—you can tell by the small antennas on the case or the inscription Wireless on the stickers. For desktop PCs, things are more complicated: if the motherboard doesn't have a built-in module (which is 90% of the time), you'll need USB adapter or PCIe card.

You can check the presence of the adapter in Windows via device Manager:

1. Click Win + X and select "Device Manager".
2. Expand the "Network adapters" branch.
3. Look for devices with words Wireless, Wi-Fi, 802.11 or brand names: Intel Wireless-AC, Qualcomm Atheros, Realtek RTL8xxx.

⚠️ Attention: If the list only Ethernet adapter (For example, Realtek PCIe GbE Family Controller) — there's no built-in Wi-Fi module. You'll have to buy an external one.

For users Linux or macOS The check is performed via the terminal:

• 🐧 Linux: enter the command

  lspci | grep -i network

  or

  lsusb

  for USB adapters.
• 🍎 macOS: Open System Information (Apple → About This Mac → System Report) and check the “Network → Wi-Fi” section.

2. Connect to Wi-Fi via the built-in adapter (Windows 10/11)

If the adapter is detected but the computer won't connect to the network, follow these instructions. The process is almost identical for Windows 10 And Windows 11, we will point out the differences separately.

Step 1: Turn on Wi-Fi

• 🔄 On your laptop keyboard, find the key with the antenna icon (often combined with F2–F12). Press it in combination with Fn (For example, Fn + F2).
• 🖱️ Desktop PCs: Enabled programmatically - via the notification panel or settings.
• 🔧 In Windows 11 The Wi-Fi icon may be hidden under the "Hidden icons" button (the up arrow on the taskbar).

Step 2: Find and connect to the network

1. Click on the icon Wi-Fi on the taskbar (in the lower right corner).
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 (security key). If you don't know the password, look it up on the router sticker or in the router's web interface (192.168.0.1 or 192.168.1.1).
4. Check the box "Connect automatically" and click "Next".

Check if Wi-Fi is enabled on your router (the indicator should be on)

Update your network adapter driver

Restart your computer and router

Try connecting to a different network (for example, from a phone)

-->

Step 3: Checking the connection

Once successfully connected, "Connected" will appear next to the network name. To verify that your internet connection is working:

1. Open your browser and try to load any website (for example, google.com).
2. If websites don't open, but the icon shows a connection, check your settings. DNS (more on this in the section on errors).

⚠️ Note: If you receive the error "Unable to connect to this network" after entering your password, try forgetting the network (right-click on its name → "Forget") and reconnecting. Sometimes changing the security type in your router settings helps. WPA3 on WPA2-PSK.

3. Setting up Wi-Fi via a USB adapter

If your computer doesn't have a built-in Wi-Fi module, the easiest way to add one is to buy one. USB adapterThey cost from 300 rubles (for example, TP-Link TL-WN725N) and connect like a regular flash drive. The main thing is to choose an adapter that supports modern standards (Wi-Fi 5 or Wi-Fi 6), if your router supports them.

Step 1: Connecting the Adapter

• 🔌 Insert the adapter into an available USB port. It is preferable to use a port USB 3.0 (blue connector) for stable operation.
• 💿 If Windows doesn't automatically recognize the device, install the driver from the disc (if included) or download it from the manufacturer's website.

Step 2: Installing Drivers

For most chip-based adapters Realtek or Ralink Drivers are installed automatically through Windows UpdateBut sometimes manual installation is required:

1. Download the driver from the official website (for example, for TP-Link — tp-link.com/ru/support).
2. Run the installer and follow the instructions.
3. Restart your computer.

Step 3. Connecting to the network

After installing the drivers, the USB adapter will appear in Device Manager as a network adapter. The next steps are identical to connecting via the built-in module (see Section 2).

4. Connecting to a hidden Wi-Fi network

Some networks (for example, in offices or hotels) may be hidden - their names (SSID) are not broadcast. Connecting to them is a bit more difficult, but the process takes no more than a minute.

Instructions for Windows:

1. Open Settings (Win + I) → “Network and Internet” → “Wi-Fi”.
2. Click "Manage known networks" → "Add new network".
3. Enter:
   • Network Name (SSID) - check with the administrator or look at the router.
   • Security type - usually WPA2-Personal or WPA3-Personal.
   • Security key (password).

Check the box "Connect automatically" and save.

For Linux (Ubuntu/Debian) use the command:

nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD" hidden yes

On macOS:

1. Open System Preferences → Network.
2. Select Wi-Fi → "Additionally".
3. In the Favorite Networks section, click "+" and add the hidden network details.

⚠️ Please note: Hidden networks do not provide additional security - they SSID It can still be determined using specialized utilities (for example, Wireshark or inSSIDer). Their main advantage is the reduction in the number of random connections.

5. Using your smartphone as a Wi-Fi hotspot

If you don't have a router handy but need internet urgently, you can share Wi-Fi from your smartphone. This method is suitable for temporary connections, as it quickly drains your phone's battery and may limit speed.

For Android:

1. Open Settings → Network & Internet → Hotspot & Tethering.
2. Select "Wi-Fi Hotspot" and turn it on.
3. Set up a network name (SSID) and password (usually by default 12345678).
4. On your computer, connect to this network as you would a regular network.

For iPhone (iOS):

1. Open Settings → Personal Hotspot.
2. Enable "Allow others" and set a password.
3. On your PC, select the network with the name of your iPhone (e.g. iPhone from Ivan).
How to save traffic when sharing from your phone?

Use data compression in your browser (for example, Lite mode in Chrome).

Turn off automatic app and Windows updates.

Disable background downloads in Steam, Epic Games, and other launchers.

Set a traffic limit in the hotspot settings (available on some Android devices).

Please note the limitations:

• 📶 Many operators block tethering or limit speeds. For example, Megaphone And Beeline may reduce speed to 64 Kbps after 10 GB.
• 🔋 Wi-Fi sharing puts a heavy strain on the battery—your phone's battery can run out in 2–3 hours.
• 🌐 Some websites (such as banking websites) may block access when a mobile IP is detected.

6. Solving common connection problems

Even after proper setup, Wi-Fi may be unstable or not connect at all. Let's take a look. top 5 mistakes and their solutions.

Problem 1: "No connections available" or "Wi-Fi is disabled"

• 🔌 Check if the adapter is turned on Device Manager (there should be no down arrow next to the name).
• 🔄 Reboot your router (pull the plug for 30 seconds).
• 🛠️ Update the adapter driver (download from the manufacturer's website, not through Windows Update).

Problem 2: There is a connection, but the Internet does not work

• 🌐 Check your settings IP and DNS:
  1. Open Control Panel → Network and Internet → Network and Sharing Center.
  2. Select your network → Properties → Internet Protocol Version 4 (TCP/IPv4).
  3. Set up automatic IP and DNS acquisition (if that doesn't help, enter Google's DNS: 8.8.8.8 And 8.8.4.4).
4. 🔒 Make sure that the router is not turned on parental control or blocking by MAC address.

Problem 3: Constant connection breaks

• 📡 Change the Wi-Fi channel in the router settings (for example, from auto on 6 or 11).
• 🔄 Disable power saving for the adapter:
  1. Open Device Manager → Network Adapters.
  2. Right-click on the adapter → “Properties” → “Power Management”.
  3. Uncheck "Allow the computer to turn off this device to save power."

Issue 4: Error: "The network settings saved on this computer do not meet the requirements of this network"

This error occurs when the security type does not match (for example, the router is configured to WPA3, and the computer tries to connect as WPA2). Solutions:

• 🔧 Go to your router settings (192.168.0.1) and change the security type to WPA2-PSK.
• 🗑️ Remove the network from known connections and reconnect.

Problem 5: Slow Wi-Fi speed

If the speed is below 10 Mbps with a 100+ Mbps tariff:

• 📶 Check which Wi-Fi standard your adapter uses. For example, 802.11n (Wi-Fi 4) is limited to 150 Mbps, and 802.11ac (Wi-Fi 5) - up to 1 Gbps.
• 🔌 Connect your computer to the router with a cable and check the speed. If it's still low, the problem is with your ISP.
• 🔄 Switch your router to a different range 5 GHz (if supported) - there is less interference.

7. Alternative ways to connect to Wi-Fi

If standard methods don't work, consider these options:

Method 1: Connecting via WPS

WPS (Wi-Fi Protected Setup) allows you to connect to your router without entering a password—just press a button on the router. Instructions:

1. Find the button WPS on the router (usually with an icon of two arrows forming a circle).
2. On your computer, select the network and click Connect via WPS.
3. Click the button WPS on the router within 2 minutes.

⚠️ Attention: WPS This feature is considered unsafe—attackers can guess your PIN code within a few hours. Disable this feature in your router settings after use.

Method 2: Connecting via Ethernet adapter with Wi-Fi bridge

If you have a free router, you can use it as bridge (repeater) for connecting a PC via cable:

1. Connect the bridge router to the main router via Wi-Fi (mode WISP or Repeater).
2. Connect your computer to the bridge via Ethernet cable.
3. Configure IP addressing manually if automatic acquisition does not work.

Method 3: Powerline adapters (Internet via electrical wiring)

If the Wi-Fi signal is weak, but there are sockets, use Powerline adapters (For example, TP-Link TL-PA4010). They transmit the internet signal through electrical wiring:

1. Connect one adapter to the router via Ethernet and plug it into the socket.
2. Plug the second adapter into a socket near the computer and connect them with a cable.
3. No setup required - devices sync automatically.

8. Wi-Fi Security: How to Protect Your Connection

Once you have successfully connected, don't forget to secure your network. Here 5 essential steps:

• 🔐 Change the default password for your router (usually admin/admin) to a complex one (for example, through a generator KeePass).
• 🔄 Update your router firmware—outdated versions contain vulnerabilities.
• 📡 Turn off WPS and a guest network if you don't use them.
• 🌐 Turn on firewall on the router (section Security → Firewall).
• 🔍 Check the connected devices in the router's web interface (section DHCP Clients or Connected Devices).

Important: If your router supports WPA3, turn it on instead WPA2 — is a new encryption standard that is resistant to most attacks.

For additional protection you can use VPN (For example, ProtonVPN or Windscribe), especially when connecting to public networks. This will hide your real IP address and encrypt your traffic.
