How to connect a laptop to a new Wi-Fi network: instructions for Windows, macOS, and Linux

Connecting a laptop to a new wireless network for the first time can often be a headache—especially if you've moved, changed providers, or purchased a new router. Even experienced users sometimes encounter authentication errors, limited network access, or a complete lack of signal. In this article, we'll cover all connection methods, from basic password entry to manual network configuration in different operating systems.

We won't limit ourselves to the standard "find the network and enter the password" instructions. We'll look at the nuances: what to do if Wi-Fi is not showing up in the list.How to connect to a hidden network, why a laptop might "see" the network but not connect, and how to check if your antivirus is blocking your connection. Also, how to protect yourself from data leaks when connecting to public networks.

The instructions are valid for Windows 10/11, macOS Sonoma/Ventura and popular distributions Linux (Ubuntu, Mint, Fedora). If you have a rare laptop model (for example, with a non-standard Wi-Fi module) or a specific router (like ASUS RT-AX88U Pro with proprietary settings), some steps may differ - we will warn you about this separately.

1. Preparation: What to check before connecting

Before attempting to connect your laptop to a new network, make sure the problem isn't with your router hardware or settings. Here's 4 key points, which are worth checking in advance:

• 🔌 The router is turned on and working.The power indicator should be green or blue (white on some models). If it's blinking orange, the device is booting or has experienced a failure.
• 📶 Wi-Fi is being distributedThe wireless network light on the router body should be on (usually indicated by wavy lines). If it's off, press the button. WPS/Wi-Fi or check the settings.
• 🔐 You know the correct passwordUsers often confuse their ISP account password with their Wi-Fi password. The latter is usually found on the router's sticker (field Wi-Fi Password or Network Key).
• 💻 The laptop's Wi-Fi adapter is turned on.. On some models (Lenovo ThinkPad, HP EliteBook) there is a physical switch or a key combination (Fn + F2, Fn + F12) to disable wireless modules.

If you are connecting to the network for the first time, pay attention to its safety standardModern routers usually use WPA3, but some older devices (eg. TP-Link TL-WR841N versions before 2018) can only work with WPA2This is important because Windows 11 by default tries to connect via WPA3, and if the router does not support it, the connection will not be established.

⚠️ Attention: If you are connecting to public network (In cafes, airports, hotels), never use automatic connection features. Attackers can create a fake network with a similar name and intercept your data.

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

In most cases, the connection is Windows This happens automatically, but sometimes manual adjustments are required. Let's consider both options.

Method 1: Standard connection via the taskbar

This is the simplest method that works in 90% of cases:

1. Click on the icon Wi-Fi in the lower right corner of the taskbar (next to the clock).
2. In the list of available networks, find the name of yours (SSID) and click on it.
3. Enter your password and click Connect.
4. If you are asked "Allow other devices on this network to find your PC?", select Yes (for home network) or No (for public).

If the network does not appear in the list, try refreshing it by clicking Refresh (round arrow at the top of the list). If this doesn't help, move on to Method 2.

Method 2: Connecting via Settings (if the network is hidden)

Some chains (especially corporate or hotel ones) may be hidden — their name isn't broadcast, and you can only connect to them manually. Here's how:

1. Open Start → Settings → Network & Internet → Wi-Fi.
2. Click Managing known networks → Add a new network.
3. Enter:
   • 📡 Network name (SSID) — the exact name (case is important!).
   • 🔒 Security type - usually WPA2-Personal or WPA3-Personal.
   • 🔑 Security key — Wi-Fi password.

Check the box Connect automatically and press Save.

If you receive the error "We can't connect to this network" after entering your password, check:

• 🔤 The correctness of the entered password (sometimes letters O And 0 or I And 1 (they are confused).
• 📡 Network range: if the router only works in 5 GHz, and your laptop only supports 2.4 GHz (relevant for older models), you won’t be able to connect.
• 🛡️ Firewall settings: temporarily disable it (Control Panel → Windows Defender Firewall → Turn on or off) and try connecting again.

Make sure Airplane mode is turned off

Check if the Wi-Fi adapter is enabled in Device Manager.

Update your network card driver (if the network is not visible)

Reboot the router (unplug for 30 seconds)-->

3. Connecting on macOS (MacBook, iMac)

On devices Apple The Wi-Fi connection process is as simple as possible, but there are some nuances with security settings and ranges.

Standard connection

To connect to a new network:

1. Click on the icon Wi-Fi in the top panel (on the right).
2. Select the desired network from the list.
3. Enter your password and click Connect.

If the network is secure WPA3, and yours MacBook released before 2018, may need to be updated macOS to the latest version or temporarily switch the router to WPA2.

If the network is not visible or the connection is reset

Here are common causes and solutions:

MacBooks with the M1/M2 chip may experience issues connecting to 6 GHz networks (Wi-Fi 6E). If your router supports this band, try disabling it in the router settings or updating macOS to version 13.3 or later.

4. Connecting on Linux (Ubuntu, Mint, Fedora)

In distributions Linux The connection process depends on the desktop environment you are using (GNOME, KDE, XFCE) and network manager (NetworkManager, Wicd). Let's consider a universal method via the terminal and graphical interface.

Method 1: Via the GUI (NetworkManager)

If you use Ubuntu or Linux Mint:

1. Click on the network icon in the upper right corner.
2. Select the desired network and enter the password.
3. If the network is not listed, click Connect to a hidden network and enter SSID manually.

If the Internet doesn't work after connecting, check your settings. DNS:

sudo nano /etc/resolv.conf

Add the following lines:

nameserver 8.8.8.8
nameserver 8.8.4.4

Method 2: Via the terminal (for advanced users)

If the graphical interface is not available or you prefer the console, use the command nmcli:

# View available networks
nmcli dev wifi list

Connecting to the network
nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD"

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

If an error occurs Activation of network connection failed, check:

• 🔌 Is the service working? NetworkManager (sudo systemctl status NetworkManager).
• 🔧 Does your Wi-Fi adapter support the selected encryption type (iw list | grep "Cipher").
• 📡 Doesn't it block? rfkill wireless connections (rfkill list).

⚠️ Note: In some distributions (for example, Arch Linux) NetworkManager is not installed by default. If the commands nmcli No, install it via package manager: sudo pacman -S networkmanager.

5. Solving common 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.

Problem 1: "Connected, no internet access"

This means the laptop is connected to the router, but it can't access the network. Reasons:

• 🔌 Problems with the provider — Check if your internet connection is paid for or call support.
• 🔧 Incorrect IP settings — try to get IP automatically:
  1. On Windows: Settings → Network → Wi-Fi → Manage known networks → Properties → IP Settings → select Automatic (DHCP).
  2. On macOS: System Preferences → Network → Advanced → TCP/IP → select Use DHCP.

🔄 Router failure - reboot it (pull the plug for 30 seconds).

Problem 2: The laptop does not see the network, but other devices do

Possible causes and solutions:

Problem 3: Constant connection drops

If your Wi-Fi keeps disconnecting, try:

• 🔋 Disable adapter power saving (Windows):
  1. Open Device Manager → Network Adapters.
  2. Find your Wi-Fi adapter (e.g. Intel Wi-Fi 6 AX200), right-click → Properties.
  3. Go to the tab Power management and uncheck the box Allow the computer to turn off this device to save power.

📡 Change the Wi-Fi channel on your routerIf neighboring networks are on the same channel, interference may occur. Go to your router settings (192.168.1.1 or 192.168.0.1) and select the channel manually (for example, 6 or 11 for 2.4 GHz).

🔄 Update your router's firmwareOutdated software may cause instability.

How do I know which Wi-Fi channel is the freest?

Use network analysis applications such as:

- WiFi Analyzer (Android)

- NetSpot (Windows/macOS)

- linssid (Linux)

They will show the channel load and help you choose the freest one.

6. Security: How to protect yourself when connecting

Connecting to a new Wi-Fi network always carries a security risk, especially when it comes to public hotspots. Follow these guidelines to minimize threats:

• 🔐 Use a VPNEven if the network is secure, a VPN encrypts all traffic. Free options: ProtonVPN, Windscribe (with traffic limit).
• 🛡️ Turn off file sharing:
  • On Windows: Settings → Network → Wi-Fi → Manage known networks → Properties → Set "Make this PC undiscoverable".
  • On macOS: System Preferences → Sharing and uncheck all the boxes.
• 🚫 Do not use automatic connection functionsIn your Wi-Fi settings, disable the "Connect automatically" option for public networks.
• 🔄 Update your operating system. Outdated OS versions are vulnerable to attacks via Wi-Fi (for example, the vulnerability Kr00k V WPA2).

If you are connecting to guest network (for example, at a hotel or airport), never enter personal information on websites without HTTPS (Check the lock icon in your browser's address bar.) Attackers can spoof login pages and steal logins and passwords.

⚠️ Note: Some public networks require registration through port protocols (For example, PPPoE). If, after connecting, a page opens with login/password fields, but you don't know these details, check with the establishment's administrator. Do not enter your social media or email information!

7. Additional settings for advanced users

If standard methods don't work, you can try manually configuring network settings. This is relevant for corporate networks where specifying IP, DNS or safety certificates.

Setting up a static IP

Sometimes the provider or network administrator requires you to use a fixed IP addressHere's how to ask it:

On Windows:

1. Open Settings → Network → Wi-Fi → Manage known networks.
2. Select your network → Properties.
3. In the section IP settings select Manually.
4. Turn on IPv4 and enter:
   • IP address: For example, 192.168.1.100 (the last digit must be unique within your network).
   • Subnet mask: usually 255.255.255.0.
   • Gateway: router address (for example, 192.168.1.1).
   • DNS: can be specified 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).

On macOS:

1. Open System Preferences → Network → Wi-Fi → Advanced.
2. Tab TCP/IP → select Manually.
3. Enter the same parameters as for Windows.

Connecting to a network with Enterprise security (WPA2/WPA3-Enterprise)

These networks are used in universities and offices and require a login/password or certificate. Setup:

On Windows:

1. In the list of networks, select the desired one and click Connect.
2. In the field Security type select WPA2-Enterprise or WPA3-Enterprise.
3. Enter your authentication details (usually PEAP or TTLS).

On Linux (via nmcli):

nmcli connection add type wifi con-name "UnivWiFi" ifname wlo1 ssid "UnivWiFi"
nmcli connection modify "UnivWiFi" wifi-sec.key-mgmt wpa-eap
nmcli connection modify "UnivWiFi" 802-1x.eap peap
nmcli connection modify "UnivWiFi" 802-1x.phase2-auth mschapv2
nmcli connection modify "UnivWiFi" 802-1x.identity "your_login"
nmcli connection modify "UnivWiFi" 802-1x.password "your_password"

⚠️ Attention: Settings Enterprise-networks are often tied to MAC address devices. If the internet doesn't work after connecting, check with the network administrator to see if you need to register your MAC.
