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

Wireless internet has become an integral part of everyday life, but connecting to Wi-Fi on your computer can sometimes be challenging. This is especially true if you're setting up your laptop for the first time or encountering issues after a system update. This article will help you understand all the nuances, from basic connection steps to troubleshooting complex errors.

We'll cover not only the standard methods through the control panel, but also alternative options for different operating systems. You'll learn how to check adapter drivers, what to do if your network isn't listed, and how to boost a weak signal. The instructions are adapted for Windows 10/11, Linux And macOS taking into account the latest updates of 2026.

1. Preparing for connection: checking the equipment

Before attempting to connect to Wi-Fi, make sure your computer is physically capable of doing so. Modern laptops come with built-in Wi-Fi adapters, and for desktop PCs an external module may be required.

To check if the adapter is available Windows:

1. Click Win + R, enter devmgmt.msc and press Enter
2. Expand the Network Adapters section.
3. Find devices with names Wireless, Wi-Fi or 802.11

Look for antennas on the laptop case.

Check the Network Adapters section in Device Manager.

Make sure the adapter is not disabled in BIOS.

Connect an external adapter if there is no built-in one-->

If the adapter is not listed, it may be disabled in the BIOS or drivers may need to be installed. Linux check the presence of the adapter with the command:

lspci | grep -i network

⚠️ Note: On some motherboards ASUS And Gigabyte In 2023-2026, the Wi-Fi adapter may be disabled by default in the BIOS under the name "Wireless LAN Radio Control".

2. Standard connection via the control panel

The easiest way to connect to Wi-Fi in Windows 10/11:

1. Click on the network icon in the lower right corner of the taskbar
2. Select the desired network from the list
3. Enter your password and click "Connect"

On macOS the process is similar:

1. Click on the Wi-Fi icon in the top bar
2. Select a network
3. Enter your password when prompted.

For Linux (for example Ubuntu):

1. Click on the network icon in the upper right corner
2. Select "Edit Connections"
3. Add a new network by entering the SSID and password.

Windows 10/11|macOS|Linux|Other-->

If the network does not appear in the list, try refreshing the list of networks using the "Refresh" button or rebooting the router. In urban areas with a large number of access points (more than 20), some adapters may not show networks on channels 12-14 due to regional restrictions..

3. Connection via command line

An alternative method for advanced users is to connect via netsh V Windows:

netsh wlan connect name="Network_Name" ssid="Network_Name"

For Linux use nmcli:

nmcli device wifi connect "Network_Name" password "password"

These commands are useful when:

• 🖥️ The GUI is unresponsive
• 🔄 Need to quickly reconnect according to a schedule
• 🛠️ Automation via scripts is required

⚠️ Warning: When using the command line in Windows The network name (SSID) is case-sensitive. If the network is called "MyWiFi" and you enter "mywifi," you won't connect.

4. Troubleshooting driver issues

A common reason for connection failure is outdated or missing drivers. Windows:

1. Open Device Manager (devmgmt.msc)
2. Find the adapter in the "Network adapters" section.
3. Right-click → "Update driver"

For Linux You may need to install proprietary drivers:

sudo apt install firmware-iwlwifi

5. Connecting to hidden networks

Some networks don't broadcast their network name (SSID) for increased security. To connect to such a network:

IN Windows:

1. Open Settings → Network & Internet → Wi-Fi
2. Click "Manage known networks"
3. Select "Add New Network"
4. Enter the network name, security type, and password.

IN macOS:

1. Open System Preferences → Network
2. Select Wi-Fi → "Advanced"
3. In the Preferred Networks section, add a new network.

For Linux through nmcli:

nmcli connection add type wifi con-name "Connection_Name" ifname wlp3s0 ssid "Hidden_Network_Name"
nmcli connection modify "Connection_Name" wifi-sec.key-mgmt wpa-psk
nmcli connection modify "Connection_Name" wifi-sec.psk "Password"
nmcli connection up "Connection_Name"

6. Troubleshooting connection issues

If the connection fails, try these steps:

• 🔄 Restart your router and computer
• 🔑 Make sure you are entering the correct password (check the case)
• 📡 Check if the router is in "5 GHz Only" mode with the old adapter
• 🛡️ Temporarily disable your firewall and antivirus
• 🔧 Reset network settings: netsh winsock reset And netsh int ip reset

For diagnostics in Windows use:

ping 8.8.8.8
nslookup google.com
tracert ya.ru

⚠️ Note: On some corporate laptops (Dell Latitude, HP EliteBook) software for managing wireless networks can be installed (for example, Intel PROSet), which blocks the default Windows settings. In this case, use the manufacturer's connection utility.

7. Signal and speed optimization

A weak signal or slow speed may be caused by:

• 📶 Long distance to the router
• 🏢 Obstacles (walls, furniture)
• 📡 Channel overload with other devices
• 🔋 Saving energy on your laptop

To improve your connection:

1. Move the router to the central part of the room
2. Use the 5 GHz band for closely spaced devices
3. Configure QOS on your router to prioritize traffic
4. Disable power saving mode for your Wi-Fi adapter

IN Windows Disabling power saving:

1. Open Device Manager
2. Find your Wi-Fi adapter
3. In the properties, on the "Power Management" tab, uncheck "Allow the computer to turn off..."

8. Alternative connection methods

If Wi-Fi isn't working at all, consider these alternatives:

• 🌐 Connection via Ethernet (cable)
• 📱 Using your phone as a hotspot
• 📡 4G/5G USB modem
• 🔗 Powerline adapters (Internet via electrical wiring)

To connect via Android-telephone:

1. Activate the modem mode in the settings
2. Connect your phone to your PC via USB
3. Select "USB Modem" in the hotspot settings

This temporary solution will help you stay connected until you resolve the issue with your main Wi-Fi connection.
