How to Connect a Computer to Wi-Fi Wirelessly: 5 Proven Methods

Connecting your computer to the internet wirelessly via Wi-Fi has become the de facto standard—even desktop PCs now come with built-in adapters, and inexpensive USB dongles are available for other devices. However, many users still encounter problems when first connecting: networks aren't visible, passwords aren't accepted, or the connection keeps dropping. This article will help you understand all the nuances—from choosing an adapter to setting up hidden networks and troubleshooting common errors.

We'll cover not only basic connection methods through the Windows interface, but also alternative methods for Linux/MacOS, as well as rare cases where standard solutions don't work. We'll pay special attention to troubleshooting: why a computer might not see the network, how to check adapter drivers, and what to do if the connection speed suddenly drops. At the end of the article, you'll find an FAQ with answers to the most frequently asked questions and a compatibility chart for adapters with different Wi-Fi standards.

1. Check hardware compatibility: Does your PC have a Wi-Fi adapter?

Before attempting to connect to the network, make sure your computer is physically capable of doing so. Modern laptops and all-in-one PCs almost always come with a built-in Wi-Fi module, but desktop PCs often require additional hardware. Here's how to check for an adapter:

• 🖥️ Windows 10/11: click Win + X → select device Manager → expand the tab Network adaptersLook for devices with names like Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA9377).
• 🐧 Linux: Enter the command in the terminal

  lspci | grep -i network

  or

  lsusb | grep -i wireless

  - if there is an adapter, you will see its model.
• 🍎 MacOS: click on the icon Apple → About this Mac → System Report → Net. In the section Wi-Fi Information about the adapter should be displayed.

If there is nothing mentioned in the list of devices Wi-Fi or Wireless, your PC requires an external adapter. These can be divided into three types:

⚠️ Attention: If you use USB extension cable For an adapter, its length should not exceed 1.5 meters, otherwise the signal will be lost. For stable operation, choose extension cords with shielded cable.

2. Connecting to Wi-Fi in Windows 10 and 11: Step-by-step instructions

The standard connection method through the Windows interface works for 90% of users. Here's how to do it correctly:

1. Activate Wi-Fi: Click the network icon in the lower right corner of the screen (next to the clock). If there is no icon, check whether the adapter is turned on with a physical button (on some laptops) or in Device Manager.
2. Select network: Find your network in the list of available networks. If it's not there, refresh the list using the button. Refresh or check if the network is hidden (more on that below).
3. Enter password: Click on the network name, enter the password and press NextIf the password is correct, the connection will be established automatically.

If an error appears after entering the password "Unable to connect to this network", try the following steps:

Make sure CAPS LOCK is off (password is case sensitive)

Reboot the router (turn it off for 30 seconds)

Forget the network in the settings and reconnect

Update your Wi-Fi adapter driver-->

To manually configure the network (for example, if the IP address is not assigned automatically):

1. Go to Settings → Network and Internet → Wi-Fi.
2. Select Managing known networks → click on your network → Properties.
3. Scroll down to IP settings and select Manually.
4. Enter the IP address (eg. 192.168.1.100), subnet mask (255.255.255.0), gateway (your router's IP) and DNS (you can use 8.8.8.8 from Google).

⚠️ Attention: If you are connecting to public network (in a cafe, airport), never choose the option "Make this computer discoverable" in network settings. This could expose vulnerabilities to hackers.

3. Connect to a hidden Wi-Fi network (SSID is not broadcast)

Some networks are set up so that their name (SSID) is not displayed in the general list. This is done for additional security, but it complicates the connection. To connect to such a network:

IN Windows 10/11:

1. Open Settings → Network and Internet → Wi-Fi.
2. Click Managing known networks → Add a new network.
3. Enter the network name (SSID), select the security type (WPA2-Personal or WPA3-Personal) and enter the password.
4. Check the box "Connect automatically" and save.

IN Linux (Ubuntu/Debian):

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

IN MacOS:

1. Open System Preferences → Network.
2. Select Wi-Fi → Other networks.
3. Enter Network name, select Security and enter the password.

4. Setting up Wi-Fi via the command line (for advanced users)

Sometimes the Windows GUI can crash and it's easier to connect to the network through command line or PowerShellThis method is also useful for automating connections (e.g. via scripts).

Here are the basic commands:

• 📡 View available networks:

  netsh wlan show networks

  If there are no networks, refresh the list:

  netsh wlan show networks mode=bssid

• 🔑 Network connection:

  netsh wlan connect name="NETWORK_NAME" ssid="NETWORK_NAME"

  For a network with a password, first save the profile:

  netsh wlan add profile filename="C:\path\to\file.xml"

  (the profile file can be created via netsh wlan export profile on another PC).

• 🔄 Deleting a network from memory:

  netsh wlan delete profile name="NETWORK_NAME"

For Linux (distributions based on systemd):

sudo nmcli dev wifi list # Show networks
sudo nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD" # Connect

5. Troubleshooting: Why your computer can't see Wi-Fi or connect

If your PC refuses to connect to the network, the cause could be software-related (drivers, settings) or hardware-related (failed adapter, interference). Let's look at some common scenarios:

Critical error: If the adapter stops working after a Windows update, the system most likely installed an incompatible driver. In this case, download the driver from the adapter manufacturer's official website (not through Windows Update) and install it manually through Device Manager.

To check signal quality in Windows:

1. Open Command line on behalf of the administrator.
2. Enter:

   netsh wlan show interfaces

3. Pay attention to the parameter Signal (signal). If it's below 60%, try moving the router or using repeater.

⚠️ Attention: If you use USB adapter and notice frequent breaks, try connecting it through USB 2.0 port (black) instead of USB 3.0 (blue). Some adapters don't work well with USB 3.0 due to interference.

6. Alternative wireless connection methods

If standard methods don't work, you can use workarounds. They're less convenient, but sometimes they can save you in critical situations.

• 📱 Sharing Internet from your phone: turn it on on your smartphone Access point (Android) or Modem mode (iPhone) and connect to it like a regular Wi-Fi network. The downside is limited data and rapid battery drain.
• 🖧 Wi-Fi Direct: If you have another computer with network access, you can create a direct network between the devices (in Windows: Settings → Devices → Add Bluetooth or other device → Everything else → Wi-Fi Direct).
• 🌐 Powerline adapters: If the router is far away, use adapters that transmit the Internet through electrical wiring (for example, TP-Link AV600). They are not wireless, but they eliminate the need to run a cable.

For Linux there is a unique way to connect through wpa_supplicant (Wi-Fi management utility):

1. Open terminal and enter:

   sudo wpa_passphrase "NETWORK_NAME" "PASSWORD" | sudo tee /etc/wpa_supplicant.conf

2. Connect to the network:

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

   (replace wlan0 to your interface, if necessary).

3. Get an IP address:

   sudo dhclient wlan0

7. Connection Optimization: How to Speed ​​Up Wi-Fi on Your Computer

Even if the connection is established, the speed may be slower than expected. Here's how to improve it:

• 📶 Change the channel on the router: use free utilities like Wi-Fi Analyzer (Android) or inSSIDer (Windows) to find the least crowded channel in the 5 GHz band.
• 🔄 Update your router firmware: go to the router control panel (usually at the address 192.168.1.1) and check for updates in the section System or Administration.
• 🖧 Configure QoS: enable it in your router settings Quality of Service (QoS) and set the priority for your PC by MAC address.
• 🛡️ Disable background updates: In Windows, disable automatic app updates via Settings → Update & Security → Advanced Options → Delivery Optimization.

For gaming PCs or streaming is recommended:

• Use range 5 GHz (less interference, higher speed).
• Enable the mode in the adapter settings 802.11ac or 802.11ax (if supported).
• Set a static IP address for the PC in the router settings (DHCP reservation).

⚠️ Attention: If you use VPN, it may be artificially limiting your speed. Try disabling your VPN and checking your speed without it. Speedtest.
