Preliminary Checks: The Easy Wins
Before diving into more complex solutions, let’s cover the basic checks that often resolve the problem quickly. These are the “low-hanging fruit” of Wi-Fi troubleshooting.
Is Wi-Fi Enabled?
It might sound obvious, but accidentally disabling Wi-Fi is a common mistake. Look for the Wi-Fi icon in your system tray (usually located in the bottom-right corner of your screen). Click on it to see if Wi-Fi is turned on. There’s also usually a physical switch or function key (Fn key + a function key) on your laptop that toggles Wi-Fi on and off. Make sure this switch is in the “on” position.
Airplane Mode is a Culprit
Airplane mode disables all wireless communication on your laptop, including Wi-Fi. Ensure Airplane mode is turned off. You can usually find the Airplane mode setting in the system tray or in your laptop’s settings app. Look for an airplane icon; if it’s highlighted or turned on, click it to disable Airplane mode.
Restart Your Laptop
A simple restart can often fix temporary glitches that might be preventing your Wi-Fi from showing up. Restarting your laptop clears the system’s memory and restarts all running processes, which can resolve software conflicts or driver issues that might be affecting your Wi-Fi connection.
Restart Your Router
Just like your laptop, your router can also experience temporary issues. Restarting your router can resolve problems with the router’s firmware or configuration that might be preventing it from broadcasting its Wi-Fi signal properly. Unplug your router from the power outlet, wait for about 30 seconds, and then plug it back in. Allow the router a few minutes to fully restart before checking if your laptop can now see the Wi-Fi network.

Why is my Wi-Fi network not showing up on my laptop, even though other devices can connect?
There are several reasons why your laptop might not be detecting your Wi-Fi network while other devices can. It could be an issue with your laptop’s Wi-Fi adapter being disabled, outdated drivers, incorrect network settings, or even interference from other devices. Another possibility is that your laptop’s Wi-Fi adapter isn’t configured to use the same wireless standard as your router (e.g., 802.11ac vs. 802.11n) or is experiencing compatibility issues with the router’s broadcast settings.
To troubleshoot this, start by checking if Wi-Fi is enabled on your laptop. Look for the Wi-Fi icon in your system tray or network settings. Then, try restarting both your laptop and your router. If the problem persists, consider updating your Wi-Fi adapter drivers or checking your router’s settings to ensure it’s broadcasting on a compatible channel and using a common wireless standard that your laptop supports.
How do I check if my laptop’s Wi-Fi adapter is enabled?
The method for checking if your Wi-Fi adapter is enabled varies slightly depending on your operating system. On Windows, you can usually find this setting by going to Settings > Network & Internet > Wi-Fi. Make sure the Wi-Fi toggle is switched to the “On” position. You can also check in the Device Manager by searching for “Device Manager” in the start menu, expanding the “Network adapters” section, and ensuring your Wi-Fi adapter is not disabled or showing any error symbols.
On macOS, you can check if Wi-Fi is enabled by clicking the Wi-Fi icon in the menu bar at the top of the screen. A dropdown menu will appear showing available networks and a Wi-Fi toggle. Ensure that Wi-Fi is turned on. You can also access more detailed Wi-Fi settings by going to System Preferences > Network and selecting your Wi-Fi adapter in the left sidebar to view its status.
What does it mean to update my Wi-Fi adapter drivers, and how do I do it?
Wi-Fi adapter drivers are software that allow your operating system to communicate properly with your laptop’s Wi-Fi hardware. Outdated or corrupted drivers can cause various Wi-Fi connectivity issues, including the inability to detect networks. Updating these drivers ensures optimal performance and compatibility. A driver update resolves potential incompatibility problems between older software versions and updated operating systems.
To update your Wi-Fi adapter drivers, you can use Device Manager on Windows or System Information on macOS to identify your Wi-Fi adapter’s manufacturer and model. Then, you can either use Windows Update to automatically search for and install updated drivers, or you can manually download the latest drivers from the manufacturer’s website (e.g., Intel, Broadcom, Qualcomm). After downloading, follow the installation instructions provided by the manufacturer.
My Wi-Fi network is hidden. How can I connect to it if it’s not showing up?
If your Wi-Fi network is intentionally hidden (not broadcasting its SSID), it won’t appear in the list of available networks on your laptop. To connect, you need to manually add the network to your laptop’s network settings. This requires knowing the network’s SSID (name), security type (e.g., WPA2, WPA3), and password.
On Windows, go to Settings > Network & Internet > Wi-Fi and click “Manage known networks” or “Add a network.” Enter the SSID, security type, and password, and select the option to connect automatically if desired. On macOS, click the Wi-Fi icon in the menu bar and select “Join Other Network.” Enter the required information and click “Join.” Make sure you type the SSID and password correctly, as they are case-sensitive.
Could interference be preventing my laptop from seeing the Wi-Fi network?
Yes, interference can definitely prevent your laptop from detecting a Wi-Fi network. Wireless signals can be disrupted by various sources, including other electronic devices (microwaves, Bluetooth devices, cordless phones), physical obstructions (walls, metal objects), and even other Wi-Fi networks operating on the same channel. These interferences can weaken the signal strength, making it difficult for your laptop to detect or connect to the network.
To minimize interference, try moving your laptop closer to the router or relocating the router to a more central location, away from potential sources of interference. You can also use a Wi-Fi analyzer app or software to identify less congested channels and configure your router to use one of those channels. Experiment with different channels in your router settings to find the channel with the least interference.
What if the Wi-Fi troubleshooter on my laptop isn’t fixing the problem?
The built-in Wi-Fi troubleshooter can often automatically identify and resolve common network issues. However, if it’s not fixing the problem, it indicates that the issue may be more complex than what the troubleshooter is designed to handle. This doesn’t mean it’s useless; the troubleshooter may still provide clues about the root cause of the problem that you can investigate further.
If the troubleshooter fails, try more advanced troubleshooting steps, such as manually resetting your TCP/IP stack, flushing your DNS cache, and checking for conflicting IP addresses. You can do these tasks via the command prompt. Also, consider temporarily disabling your firewall or antivirus software to see if they’re interfering with the Wi-Fi connection. If none of these steps work, it might be a hardware issue with your Wi-Fi adapter, requiring professional repair or replacement.
Is there a way to reset my network settings to default?
Yes, both Windows and macOS offer options to reset network settings to their default configurations. This can be a useful troubleshooting step when you’ve made changes to your network settings that are causing problems, and you’re unsure how to revert them. Resetting your network settings will remove all saved Wi-Fi passwords and network configurations, so you’ll need to re-enter them after the reset.
On Windows 10 and 11, you can reset network settings by going to Settings > Network & Internet > Advanced network settings and clicking “Network reset.” This will reinstall your network adapters and reset networking components to their default settings. On macOS, you can create a new network location in System Preferences > Network, effectively resetting network settings to their default values for that location.
