How to Connect to the Internet via Wi-Fi on a Laptop: A Complete Guide

Connecting a laptop to Wi-Fi seems like a simple task—until you encounter errors like "No connections available" or "Unable to connect to this network." Even if your laptop is new and your router is configured according to the instructions, problems can arise due to outdated drivers, incorrect network settings, or conflicts with other devices. In this article, we'll cover these issues. all possible connection methods — from basic password entry to manual IP address configuration and troubleshooting.

We will pay special attention to Windows 10/11, macOS Sonoma/Ventura and popular distributions Linux (Ubuntu, Mint). We'll also look at what to do if your laptop doesn't see the network, constantly loses connection, or connects but the internet doesn't work. For convenience, we've added table with error codes and their solutions - it will help you quickly navigate without diving deep into the settings.

1. Basic Wi-Fi connection on Windows

On most laptops with Windows 10/11 Connecting to Wi-Fi takes just a few clicks. Here's the standard procedure:

1. Click on the icon Wi-Fi in the lower-right corner of the taskbar (near the clock). If the icon is not there, click the up arrow to expand the hidden icons.
2. Select your network from the list of available networks. If your network isn't listed, check that your Wi-Fi adapter is turned on (more on that below).
3. Click Connect, enter the password (if the network is protected) and confirm.

If you receive the error "Can't connect to this network" after entering your password, try:

• 🔄 Reboot the router (unplug it from the outlet for 30 seconds).
• 📶 Check the distance — if the signal is weak (1-2 bars), move closer to the router.
• 🔑 Make sure your password is correct (Case-sensitive!) To see the characters you've entered, click the eye icon 👁️ next to the field.

On Windows 11 The interface has changed slightly: now, when you first connect, the system may ask for permission to exchange data with other devices on this network. Select Yes, if you want to use printers or files from other gadgets.

⚠️ Attention: If the internet doesn't work after connecting, but there's an exclamation mark (!) next to the Wi-Fi icon, the problem may be in the settings. IP/DNSMore on this in the section on manual configuration.

2. Connecting on macOS: Features and Nuances

On laptops MacBook (and other devices Apple With macOS) Connecting to Wi-Fi is even simpler, but there are some pitfalls. For example, the system may "forget" networks after an update or block the connection due to security settings.

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 your network from the list. If it's not there, click Other networks... and enter the name (SSID) manually.
3. Enter your password and click Connect.

If macOS It stubbornly won't connect, try:

• 🍎 Reset network settings: go to System Preferences → Network, select Wi-Fi, press “-” (remove), then “+” (add again).
• 🔒 Remove network from saved: in the same menu, select More → Delete (find your network in the list).
• 🛠️ Update software: sometimes bugs are fixed in new versions macOS.

On MacBook with chips M1/M2/M3 There may be a problem connecting to older routers (for example, with the standard 802.11n). In this case, changing the Wi-Fi channel in the router settings will help (optimally - Channel 6 for 2.4 GHz).

3. Connecting on Linux: Terminal vs. GUI

nmcli dev wifi list # View a list of networks
nmcli dev wifi connect "NETWORK_NAME" password "PASSWORD"

If an error occurs Device not managed, which means the network is managed by another service (for example, wpa_supplicant). To fix:

sudo nano /etc/NetworkManager/NetworkManager.conf

Make sure the line managed=true not commented out (no symbol) # before it). Then restart the service:

sudo systemctl restart NetworkManager

⚠️ Attention: On some distributions (for example, Arch Linux) instead of NetworkManager can be used netctl or iwdIn this case, the commands will be different.

4. Laptop doesn't detect Wi-Fi: causes and solutions

If your laptop does not detect any networks, the problem may be:

• 🖥️ Disabled Wi-Fi adapter (hardware or software).
• 🔌 Outdated drivers (especially relevant for Windows after the update).
