Start with the simplest fixes first
Most laptop connection problems come from something turned off, not broken hardware. Before you assume the worst, check three things in this order: whether your Wi-Fi is actually on, whether you are connected to the right network, and whether airplane mode is active.
On Windows, look for the Wi-Fi icon in the bottom right corner of your screen. If it shows an X or a crossed-out symbol, Wi-Fi is off. Click it and select your network. On Mac, click the Wi-Fi icon in the top right corner and choose your network from the list. If you see "Wi-Fi: Off", click it to turn it on. On both systems, check whether airplane mode is enabled — it disables all wireless connections at once. On Windows, swipe in from the right edge or press Windows key + A to open Quick Settings. On Mac, click Control Center in the top right and look for Airplane Mode.
Key Takeaways
- Check that Wi-Fi is turned on, you are connected to the correct network, and airplane mode is off before troubleshooting anything else.
- Restart your router by unplugging it for 30 seconds, then plug it back in and wait two minutes for it to fully boot.
- If other devices connect fine, the problem is your laptop's Wi-Fi hardware or driver, not your internet service.
- Forgetting and reconnecting to your network fixes most connection problems that happen after your laptop was working fine.
- If nothing works, contact your internet provider to confirm your service is active and your router is broadcasting correctly.
Restart your router and modem
A router that has been running for weeks without a restart often stops responding to new connection requests, even though devices already connected keep working. Unplug your router from power for 30 seconds, then plug it back in. Wait two full minutes before trying to connect — the router needs time to boot up and establish a connection with your modem.
If you have a separate modem (a box between your wall outlet and router), unplug that too. Unplug the modem first, wait 30 seconds, plug it back in, wait for its lights to stabilize, then unplug and restart the router. This order matters because the modem needs to connect to your internet service before the router can distribute that connection.
Check whether other devices can connect
Open your phone or tablet and try to connect to the same Wi-Fi network. If it connects and works, your internet service and router are fine — the problem is your laptop. If your phone cannot connect either, the problem is your router or internet service, not your laptop.
If your phone connects but your laptop does not, your laptop's Wi-Fi hardware or the software that controls it (called a driver) is the issue. This is fixable but requires different steps depending on whether you use Windows or Mac.
Forget and reconnect to your network on Windows
Windows sometimes stores incorrect information about a network and refuses to connect even though the network is working. Forgetting the network and reconnecting tells Windows to start fresh. Right-click the Wi-Fi icon in the bottom right corner and select "Wi-Fi" or "Network and Internet settings". Click "Manage known networks" or "Wi-Fi" depending on your Windows version. Find your network name in the list, click it, and select "Forget". Now click "Show available networks", find your network again, and click "Connect". Enter your Wi-Fi password when prompted.
If you do not remember your Wi-Fi password, you can find it on your router. Look for a sticker on the bottom or back of the router — it usually shows the network name and password. If the sticker is missing, you may need to reset the router to its factory settings, which erases your custom password and returns it to the default one printed on the sticker.
Forget and reconnect to your network on Mac
Mac stores network information in a similar way. Click the Wi-Fi icon in the top right corner and select "Open Network Preferences" or "Network Settings". Click "Wi-Fi" on the left side. Find your network name in the list on the right, click the information icon next to it, and select "Forget". Close the settings window, click the Wi-Fi icon again, and reconnect to your network by selecting it and entering your password.
If you still cannot connect after forgetting and reconnecting, restart your Mac completely. Shut down from the Apple menu, wait 30 seconds, and turn it back on. This clears temporary files that sometimes interfere with Wi-Fi.
Update or reinstall your Wi-Fi driver on Windows
Your laptop's Wi-Fi hardware needs software called a driver to communicate with Windows. If the driver is outdated or corrupted, your laptop may not connect even though the hardware works. 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 mentions Wi-Fi or wireless — it usually contains words like "802.11" or "Wireless". Right-click it and select "Update driver". Choose "Search automatically for updated driver software". Windows will search for a newer version online.
If updating does not work, right-click the same device and select "Uninstall device". Restart your laptop. Windows will automatically reinstall the driver when it boots back up. This often fixes connection problems that started after a Windows update.
Check your internet service status
If no devices can connect to your Wi-Fi, or if your phone connects but has no internet, the problem is your internet service or the connection between your modem and the internet. Look at the lights on your modem. Most modems have lights that indicate whether they are receiving a signal from your internet provider. The exact lights vary by modem type, but usually a solid green or blue light means the connection is active, and a red light or no light means it is not.
Check your internet provider's website or call their customer service number to confirm your service is active and there are no outages in your area. You can usually find the customer service number on your bill or on the provider's website. Have your account number ready when you call. If there is an outage, you will need to wait for the provider to fix it. If there is no outage but your modem shows no signal, the problem may be a loose cable between the wall and your modem, or a problem with the line itself — the provider can walk you through checking cables and may need to send a technician.
Frequently Asked Questions
Why does my laptop connect to Wi-Fi but have no internet?
Your laptop is connecting to the router but the router has no internet. Restart your modem and router using the steps above. If other devices have internet, the problem is your laptop's network settings — try forgetting and reconnecting to the network. If no devices have internet, contact your provider to check whether your service is active.
My laptop was working yesterday but will not connect today. What changed?
Your router may have restarted or lost its connection overnight. Restart it by unplugging for 30 seconds. If that does not work, your Wi-Fi password may have changed, or Windows may have corrupted its network settings — forget the network and reconnect. If you recently updated Windows, a driver update may have broken your Wi-Fi — try updating or reinstalling the driver.
How do I know if my Wi-Fi hardware is broken?
If other devices connect fine but your laptop never connects, and you have tried forgetting the network, restarting, and updating drivers, your hardware may be failing. Check whether your laptop has a physical Wi-Fi switch or keyboard shortcut to turn Wi-Fi on and off — make sure it is on. If you still cannot connect, contact your laptop manufacturer's support line with your model number.
Can I use a wired connection instead of Wi-Fi?
If your laptop has an Ethernet port (a rectangular socket larger than a USB port), you can plug in an Ethernet cable connected to your router. This bypasses Wi-Fi entirely and often works when wireless does not. Most newer laptops do not have Ethernet ports, but you can buy a USB adapter that adds one for about twenty to forty dollars.
What if I reset my router and forgot my Wi-Fi password?
Check the sticker on the bottom or back of your router — it shows the default network name and password. Write down both before you reset. To reset, hold the small reset button on the back of the router for ten seconds while it is powered on. The router will restart and return to factory settings. You can then set a new password through your router's settings page, which you access by typing the router's IP address (usually 192.168.1.1) into a web browser.
