Start with the simplest fixes first

Most laptops that won't connect to WiFi are actually connected to it already — they just don't know it yet. Before you restart anything, check three things: whether WiFi is turned on at all, whether your laptop is in airplane mode, and whether you're looking at the right network name.

Open your WiFi menu (the network icon in your system tray on Windows, or the WiFi icon in the top-right corner on Mac). If you see "WiFi is off" or a crossed-out WiFi symbol, click it to turn WiFi back on. On Windows, also check the bottom-left corner of your screen for an airplane mode toggle — if it's on, your laptop blocks all wireless signals. On Mac, hold Control and click the WiFi icon, then select "Turn WiFi On" if it's off.

Once WiFi is on, look at the list of networks your laptop can see. Your network name (called the SSID) should appear there. If it doesn't, your router may be too far away, or the router itself may have stopped broadcasting. Move closer to the router and wait 10 seconds, then refresh the network list by clicking the WiFi icon again.

Key Takeaways

  • Check that WiFi is actually turned on in your system settings and that airplane mode is off before troubleshooting anything else.
  • If your network name doesn't appear in the available networks list, move closer to the router and restart it by unplugging it for 30 seconds.
  • If you can see the network but can't connect, forget the network in your WiFi settings and reconnect by entering the password again.
  • If your laptop connects but has no internet, restart your router first, then restart your laptop — most connection problems clear this way.
  • If nothing works after these steps, contact your internet provider to confirm your service is active and your router is working.

Restart your router when the network won't appear

If your network name isn't showing up in the available networks list, your router has likely stopped working properly. The fastest fix is to restart it. Unplug the power cable from the back of your router, wait 30 seconds, then plug it back in. The lights on the front will blink as it restarts — this usually takes 2 to 3 minutes.

While the router restarts, go back to your laptop's WiFi menu and refresh it by clicking the WiFi icon again. Your network name should reappear. If it does, try connecting to it. If it still doesn't appear after the router has fully restarted, move your laptop closer to the router — sometimes distance or walls between them block the signal — and try again.

Forget the network and reconnect if you see it but can't join

Sometimes your laptop remembers an old or corrupted version of your network and refuses to connect to the real one. The fix is to forget the network entirely and reconnect from scratch.

On Windows, go to Settings, then Network & Internet, then WiFi, then Manage Known Networks. Find your network name in the list, click it, and select "Forget". On Mac, go to System Settings, then WiFi, click the Details button next to your network name, then click "Forget Network".

After you've forgotten it, go back to your WiFi menu, find your network name in the list of available networks, and click it. Your laptop will ask for the password. Type it carefully — passwords are case-sensitive, meaning capital letters matter — and click Connect. If you don't remember your password, check the sticker on the back or bottom of your router; it's usually printed there.

Check your internet connection when WiFi connects but nothing loads

Your laptop can be connected to the WiFi network but still have no internet. This means your router is working, but your internet service isn't. First, restart your router again using the same method: unplug it for 30 seconds, plug it back in, and wait for the lights to stabilize.

While the router restarts, restart your laptop as well. Shut it down completely, wait 10 seconds, and turn it back on. Once both devices have fully restarted, try opening a website in your browser. If it still doesn't load, the problem is with your internet service, not your WiFi. Contact your internet provider and tell them your router is on but you have no internet — they can check whether your service is active and whether the router is communicating with their equipment.

Update or reinstall your WiFi driver on Windows

Your laptop's WiFi driver is the software that lets it talk to your router. If the driver is outdated or corrupted, your laptop may see the network but fail to connect. On Windows, you can update it through Device Manager.

Right-click the Start button and select Device Manager. Look for "Network adapters" and click the arrow next to it to expand the list. Find the entry that contains "Wireless" or "WiFi" — it usually says something like "Intel Wireless-AC" or "Realtek Wireless". Right-click it and select "Update driver". Choose "Search automatically for updated driver software" and let Windows search. If it finds an update, it will install it and may ask you to restart your laptop.

If updating doesn't work, try uninstalling the driver instead. Right-click the same WiFi adapter and select "Uninstall device". Restart your laptop. Windows will automatically reinstall the driver when it starts up. This often clears problems that updates alone won't fix.

Check for interference or distance problems

WiFi signals travel through walls and other objects, but they weaken as they travel. If your laptop is far from the router or separated by many walls, the signal may be too weak to connect reliably. Move your laptop closer to the router — ideally in the same room — and try connecting again.

Some devices also interfere with WiFi signals. Microwaves, cordless phones, baby monitors, and some older Bluetooth devices all use the same radio frequency as WiFi. If you're using any of these near your router or laptop, move them away and try again. If you have a 5GHz WiFi network available (separate from your regular 2.4GHz network), try connecting to that instead — it's less crowded and less prone to interference, though it doesn't travel as far.

Verify your router is working correctly

Before you assume the problem is your laptop, confirm that your router itself is functioning. Look at the lights on the front of your router. Most routers have a power light, an internet light, and WiFi lights. The power light should be solid. The internet light should be solid or blinking — if it's off or red, your internet service isn't connected to the router.

Check that all cables are plugged in firmly: the power cable into the router, and the cable from your internet provider (usually called a modem cable) into the port labeled "Internet" or "WAN" on the router. If any cable is loose, push it in until it clicks. Wait 30 seconds and check whether the internet light changes. If the internet light is still off or red after 2 minutes, restart the router and contact your internet provider.

Frequently Asked Questions

Why does my laptop connect to WiFi but then disconnect after a few seconds?

This usually means your router is too far away or the signal is weak. Move closer to the router. If that doesn't help, restart both your router and laptop. If disconnections keep happening, your WiFi driver may be outdated — update it through Device Manager on Windows, or check System Preferences > Network on Mac and look for a "Renew DHCP Lease" button.

My password is correct but my laptop says it's wrong. What do I do?

Passwords are case-sensitive, so check that Caps Lock is off. If you're still stuck, forget the network on your laptop, then look at the sticker on your router and type the password exactly as it appears — including any numbers or special characters. If the password on the sticker doesn't work, you may have changed it before. Contact whoever set up your WiFi or reset the router to factory settings by holding the reset button for 10 seconds.

Can I connect to WiFi on my phone but not my laptop?

This tells you the router and internet are working, so the problem is specific to your laptop. Forget the network on your laptop and reconnect. If that doesn't work, update your WiFi driver on Windows or restart your laptop entirely. If your phone connects fine but your laptop still won't, the issue is almost certainly your laptop's WiFi hardware or driver, not your network.

What if I've tried everything and my laptop still won't connect?

At this point, your laptop's WiFi hardware may be failing. On Windows, open Device Manager and look for any warning symbols (yellow triangles) next to your WiFi adapter — this indicates a hardware problem. On Mac, hold Option and click the WiFi icon to see detailed connection information. If you see errors there, your WiFi card may need replacement. Contact your laptop's manufacturer or a repair technician.
