This article will help you understand how to properly set up Wi-Fi on laptops. Lenovo under control Windows 10/11, and also troubleshoot common problems.

We will consider not only the standard procedure for connecting to a router, but also the nuances specific to different laptop series. LenovoFor example, the owners Legion often encounter conflicts between network adapters due to gaming utilities, and in Yoga Power-saving modes may be active, blocking Wi-Fi. We'll pay special attention to diagnostics—from checking the physical switch to analyzing system logs.

If your laptop can't detect the network, constantly loses connection, or displays the error "Unable to connect to this network," you'll find step-by-step solutions here. And for those looking to optimize speed, we've prepared recommendations for selecting a router channel and setting up traffic priority.

1. Preparation: Checking the hardware components

Before delving into Windows settings, make sure the problem isn't hardware-related. Laptops Lenovo Wireless devices often come equipped with physical Wi-Fi switches or key combinations to control wireless modules. Skipping this step can leave you spending hours fiddling with software settings when a simple switch on the case would suffice.

On most models IdeaPad And ThinkPad The Wi-Fi switch is located on the side panel (usually next to the USB ports). Legion And Yoga It may not be there - a key combination is used instead. Try pressing Fn + F7 (or F5, depending on the model). On some devices, the Wi-Fi indicator lights up orange when the adapter is disconnected.

• 🔍 Check the indicators: The blue or white LED next to the antenna symbol on the laptop should be lit. If it's red or inactive, the adapter is disabled.
• 🔧 Inspect the switch: on models ThinkPad X1 Carbon And IdeaPad Flex It can be hidden under a cover or integrated into the key.
• 🔌 Connect the power: some laptops Lenovo Disable Wi-Fi in power saving mode when running on battery power.

⚠️ Attention: If the laptop has been dropped or subjected to mechanical impact, check the integrity of the Wi-Fi antennas. In models Lenovo Legion They are often attached to the screen cover - if the connection is damaged, the signal will be unstable.

2. Basic Wi-Fi setup in Windows 10/11

If the hardware is OK, we move on to software settings. Windows 10 And Windows 11 The Wi-Fi connection process is almost identical, but there are some nuances in the menu layout. Let's look at both options.

IN Windows 11 Click the network icon in the lower right corner of the taskbar (next to the clock). A panel with available networks will open. Select your network, enter the password, and click ConnectIf the network is not listed, click Network troubleshooting — the system will automatically check drivers and settings.

IN Windows 10 the path is a little longer: Start → Settings (⚙) → Network & Internet → Wi-FiHere you can not only connect to the network, but also manage known connections. Note the option Random hardware addresses — It is better to disable it if the router blocks devices with frequently changing MAC addresses.
