How to connect to Wi-Fi on a computer: 5 connection methods + troubleshooting

Connecting a computer to Wi-Fi is a basic task faced by every user. However, even in 2026, many people still encounter difficulties: the network adapter isn't visible, the password doesn't work, or the signal keeps dropping. This article will help you figure out how to properly connect to a wireless network. Windows 10/11, MacOS And Linux, and what to do if standard methods don't work.

We will consider not only the basic methods of connecting through the control panel, but also alternative options - for example, using command line or PowerShell For experienced users. We'll pay special attention to diagnosing common errors, from missing drivers to IP address conflicts. If you want to do more than just connect, you'll need to as safe and stable as possible — read on.

1. Connect to Wi-Fi via the Windows Control Panel

The easiest way is to use the built-in tools of the operating system. Windows 10 And Windows 11 The algorithm is almost identical, but there are nuances in the arrangement of interface elements.

First, make sure you have it on your PC or laptop. Wi-Fi adapterOn desktop computers it is often missing out of the box - in this case, an external USB adapter will be required (for example, TP-Link TL-WN725N or ASUS USB-AC53 Nano). Laptops usually come with a built-in module.

• 🖥️ Click the network icon in the lower-right corner of the taskbar (next to the clock). If it's not there, check if Airplane Mode is enabled.
• 🔍 In the list of available networks, find the name of yours (for example, TP-Link_5G_1234). If there is no network, refresh the list with the button Refresh.
• 🔒 Click on the network name, enter the password and press ConnectIf you've lost your password, look for it on the router's sticker or in the router's web interface.
• ✅ After a successful connection, a message will appear next to the network name. Connected.

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

1. Reboot the router (turn off the power for 30 seconds).
2. Make sure that the MAC address filter is not activated on the router.
3. Try connecting from another device (smartphone) to check the network's functionality.

2. Connecting via the command line (CMD) or PowerShell

This method is useful if the Windows graphical interface is not working correctly or you prefer to automate the process. It is also useful for problem diagnostics - for example, when the network is visible, but you can’t connect.

Open Command line as administrator (click Win + X → Terminal (Administrator)) and run the following commands:

netsh wlan show interfaces

This command will show the current status of the Wi-Fi adapter. Note the line "State" - if there Disabled, enable the adapter with the command:

netsh interface set interface "Wi-Fi" enable

To connect to the network, use:

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

Replace NETWORK_NAME to the actual name of your network (in quotation marks!). If the network is hidden (doesn't broadcast the SSID), add the parameter hidden=yes.

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

For PowerShell similar actions are performed through the module NetAdapter:

Get-NetAdapter -Name "Wi-Fi" | Enable-NetAdapter
Connect-Wifi -SSID "NETWORK_NAME" -Password "PASSWORD"

⚠️ Attention: Passwords in the command line must be entered in clear text! Make sure no one is nearby before entering any data.

3. Connecting on MacOS: Features and Nuances

On computers Apple The Wi-Fi connection process is slightly different. The main difference is a stricter security policy and automatic network management.

To connect:

1. Click on the Wi-Fi icon in the top bar (on the right). If the icon is not there, check your settings in System Preferences → Network.
2. Select a network from the list. If it is hidden, click Connect to another network and enter the SSID manually.
3. Enter your password and click Connect.

If MacOS keeps losing connection or connecting to the "wrong" network (such as a neighbor with a stronger signal), try the following:

• 📱 Open System Preferences → Wi-Fi → Advanced.
• 🔄 In the section Preferred Networks Delete unnecessary networks or drag your network to the first place in the list.
• 🛡️ Disable the option "Automatically join this network" for unnecessary access points.

On MacBook Pro/Air with a chip Apple Silicon (M1/M2/M3) there may be a problem connecting to networks on the frequency 5 GHzIn this case:

1. Reboot your router and select the mode 802.11a/n/ac (turn off ax, if it is enabled).
2. Set the channel width in the router settings 20/40 MHz instead of 80 MHz.

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

In distributions Linux Wi-Fi connection depends on the desktop environment you are using (GNOME, KDE, XFCE) and network manager (NetworkManager, wpa_supplicant). Let's consider a universal method via the terminal.

First, check if your Wi-Fi adapter is detected:

iwconfig

The output should show an interface like wlan0 or wlp3s0If it is not there, install the driver (for example, for adapters) Realtek RTL8821CE a package will be required rtl8821ce-dkms).

To connect to an open network:

sudo iwconfig wlan0 essid "NETWORK_NAME"

For a secure network (WPA/WPA2) use wpa_supplicant:

1. Create a configuration file:

   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

3. Get an IP address:

   sudo dhclient wlan0

If you use Ubuntu or Debian With NetworkManager, it’s easier to use the graphical interface:

• 🖥️ Click on the network icon in the upper right corner.
• 🔍 Select a network and enter the password.
• ⚙️ If the network is not displayed, check if Wi-Fi is enabled in the settings (nmcli radio wifi on).

⚠️ Attention: In some distributions (for example, Arch Linux) NetworkManager It is not installed by default. Install it with the command sudo pacman -S networkmanager and activate the service: sudo systemctl enable --now NetworkManager.

5. Solving common connection problems

Even if you've done everything correctly, errors can still occur. Let's look at the most common ones and how to fix them.

ipconfig /release
ipconfig /renew
ipconfig /flushdns

If the problem persists, check:

• 🔌 Is the router receiving a stable power supply (try a different power supply).
• 📶 Are there any physical obstacles between the router and the computer (walls, metal structures).
• 🔄 Is the router in the offline mode? "Only for devices with MAC filtering".

Check if the Wi-Fi indicator on your router is on.

Restart your computer and router

Update your network adapter driver

Try connecting from another device-->

6. Configuring the router for a stable connection

Sometimes the problem isn't with your computer, but with incorrect router settings. Optimizing your router settings can improve connection speed and stability.

To get started, log into your router's web interface. The address typically looks like this: 192.168.0.1 or 192.168.1.1 (check the device sticker for details). The default login and password are often admin/admin or admin/password.

Basic settings for optimization:

• 📡 Opening hours: Select 802.11n/ac (For 5 GHz) or 802.11b/g/n (For 2.4 GHz). Disable legacy standards (802.11b).
• 🔒 Safety: Use WPA2-PSK (or WPA3, if all devices support it). Disable WEP - This protocol is not secure.
• 📶 Channel: Manually select the least loaded channel (use apps like Wi-Fi Analyzer for ether analysis).
• 🔄 DNS: Replace DNS provider with 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) to speed up page loading.

If your router supports the technology MU-MIMO or Beamforming, be sure to activate these features - they will significantly improve coverage and speed for multiple devices simultaneously.

⚠️ Attention: After changing the router settings, save the configuration (button Save or Apply) and reboot your device. Some changes (such as changing the channel) are only applied after a reboot.

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

Connecting to open or poorly secured networks can lead to data leaks, man-in-the-middle attacks, and other security risks.MITM) or even hacking your devices. Follow these rules to minimize the risks:

For home network:

• 🔐 Change your router's default password to a complex one (at least 12 characters, with numbers and special characters).
• 🛡️ Turn it off WPS - This protocol is vulnerable to brute force attacks.
• 📱 Set up MAC filtering, if you want to restrict access only to your devices.
• 🌐 Hide the SSID (network name) if you don't want it to be displayed in the public list.

For public networks (cafes, airports):

• 🛡️ Use VPN (For example, ProtonVPN or Windscribe) to encrypt traffic.
• 🔒 Turn off file and printer sharing in Windows settings (Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settings).
• 🚫 Do not access your bank or payment system accounts without a VPN.

If you suspect that someone else has connected to your network, check the list of devices in the router's web interface (section DHCP Clients or Connected Devices). Strangers MAC addresses can be blocked.
