Experiencing Wi-Fi connectivity issues on your Windows 10 laptop can be incredibly frustrating, especially when you need to work, stream, or simply browse the internet. Fortunately, most Wi-Fi problems are easily solvable with a bit of troubleshooting. This guide will walk you through a series of steps, from basic checks to more advanced solutions, to help you get your laptop back online.
Initial Checks: The Foundation of Troubleshooting
Before diving into complex solutions, it’s crucial to perform some basic checks to rule out simple causes. These initial steps often resolve the problem quickly and save you time.
Ensure Wi-Fi is Enabled
The most obvious, yet often overlooked, step is to confirm that Wi-Fi is actually enabled on your laptop. Look for the Wi-Fi icon in the system tray (usually located in the bottom-right corner of your screen). Click on the icon to open the network panel. Make sure the Wi-Fi toggle is switched to the “On” position. If it’s off, simply click it to turn it on.
You can also check the Wi-Fi status through the Settings app. Press the Windows key + I to open Settings, then go to “Network & Internet” and select “Wi-Fi.” Verify that Wi-Fi is enabled here as well.
Check Airplane Mode
Airplane mode disables all wireless communications on your laptop, including Wi-Fi. It’s easy to accidentally turn it on, so it’s important to check its status. Look for the Airplane mode icon in the system tray or access it through the Action Center (click the notification icon in the bottom-right corner). Ensure that Airplane mode is turned off. If it’s on, click the icon to disable it.
Airplane mode can also be disabled in the Settings app under “Network & Internet.”
Restart Your Router and Modem
Your router and modem are essential components of your home network, and sometimes they can experience glitches that affect Wi-Fi connectivity. A simple restart can often resolve these issues.
Unplug the power cords from both your router and modem. Wait for about 30 seconds to a minute. This allows the devices to completely reset. Plug the modem back in first, and wait for it to power on fully (the lights should be stable). Then, plug the router back in and wait for it to power on.
Once both devices are back online, check if your laptop can now connect to the Wi-Fi network.
Verify the Wi-Fi Password
Double-check that you’re entering the correct Wi-Fi password. Passwords are case-sensitive, so ensure you’re typing it accurately. If you’re unsure of the password, you can usually find it on a sticker on your router or by logging into your router’s settings page through a web browser (the instructions for accessing your router’s settings are usually found in the router’s manual).

If your Wi-Fi network isn’t showing up in the list of available networks, it indicates a more significant problem than just a weak signal. It could be due to a disabled Wi-Fi adapter, a driver issue, the network being hidden, or a problem with your router’s broadcasting capabilities. First, make sure your Wi-Fi adapter is enabled both physically (if your laptop has a physical switch) and in Windows settings.
To check in Windows, go to Settings > Network & Internet > Wi-Fi and ensure Wi-Fi is turned on. If it is on, try restarting your laptop. If that doesn’t work, go to Device Manager, find your Wi-Fi adapter under “Network adapters,” and check if it’s enabled. If it has a yellow exclamation mark, there’s likely a driver issue; try updating or reinstalling the driver. If your network is hidden, you’ll need to manually add it by going to Settings > Network & Internet > Wi-Fi and selecting “Hidden Network.” You’ll need to know the network name (SSID) and password.
How can I change my DNS server settings in Windows 10 to improve Wi-Fi performance?
Changing your DNS server settings can sometimes improve Wi-Fi performance, especially if your current DNS server is slow or unreliable. DNS servers translate domain names (like google.com) into IP addresses, which your computer uses to connect to websites. Using a faster or more reliable DNS server can speed up browsing and overall internet performance.
To change your DNS settings, open the Control Panel and go to Network and Internet > Network and Sharing Center. Click on “Change adapter settings.” Right-click on your Wi-Fi adapter and select “Properties.” In the properties window, select “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties.” Select “Use the following DNS server addresses” and enter your preferred DNS server addresses. For example, you can use Google’s public DNS servers (Preferred DNS server: 8.8.8.8, Alternate DNS server: 8.8.4.4) or Cloudflare’s DNS servers (Preferred DNS server: 1.1.1.1, Alternate DNS server: 1.0.0.1). Click “OK” to save the changes.
How do I reset my network settings in Windows 10?
Resetting your network settings can be a useful step when other troubleshooting methods have failed. This action removes all your saved Wi-Fi networks, VPN settings, and adapter configurations, returning them to their default state. It’s like giving your network a fresh start, which can resolve a variety of connection issues caused by corrupted or misconfigured settings.
To reset your network settings, go to Settings > Network & Internet > Status. Scroll down to the bottom of the page and click on “Network reset.” A warning message will appear, explaining that all your network adapters will be reset to their default configurations. Click “Reset now” to proceed. Your computer will restart automatically after the reset is complete. After the restart, you’ll need to reconnect to your Wi-Fi networks and reconfigure any VPN connections you were using.
