Start with the simplest fixes first

Most WiFi connection problems on a PC come down to something you can fix yourself in under five minutes. Before you assume the router is broken or call your internet provider, check whether WiFi is actually turned on at the device level, whether you are in range of the signal, and whether you have selected the correct network name and entered the password correctly.

On Windows, look for the WiFi icon in the bottom right corner of your taskbar—it looks like curved lines or radiating dots. If it shows an X or a crossed-out symbol, WiFi is disabled. Click it and toggle WiFi back on. On a Mac, click the WiFi icon in the top right corner of the menu bar and select your network from the list. If you see "WiFi: Off", click it to turn it back on.

If WiFi is on but you do not see your network name in the list, move your PC closer to the router. WiFi signals weaken with distance and through walls. If you still cannot see it after moving, the router itself may have an issue—we will cover that next.

Key Takeaways

  • Check that WiFi is turned on at the device level by looking for the WiFi icon in your taskbar or menu bar and toggling it if it shows as off.
  • Restart your router by unplugging it for 30 seconds, then plugging it back in and waiting two to three minutes for it to fully boot.
  • Forget the network on your PC and reconnect by selecting it again and re-entering the password, which fixes most connection drops and slow speeds.
  • Update your WiFi driver through Device Manager on Windows or System Update on Mac, since outdated drivers cause many connection failures.
  • If your PC connects to other networks but not yours, the router may need a restart or a password reset through its admin panel.

Restart the router to clear temporary connection problems

A router that has been running for weeks or months can develop temporary glitches that block new connections or drop existing ones. Restarting it clears these glitches without erasing your settings or password.

Unplug the power cable from the back of your router. Wait 30 seconds—this matters, because the router needs time to fully discharge. Plug it back in and wait two to three minutes for all the lights to stabilize. During this time, the router is booting up and reconnecting to your internet provider. Do not try to connect yet.

Once the lights stop changing, try connecting your PC to the network again. If you still cannot see the network name, or if you see it but cannot connect, move to the next step.

Forget the network and reconnect with the correct password

Your PC stores the password for each network it has ever connected to. If the password is wrong in that stored record, or if the connection settings got corrupted, your PC will fail to connect even if you type the password correctly in the moment.

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

Now reconnect: select your network from the available list and enter the password again. Make sure you type it exactly as it appears on your router or in your account—passwords are case-sensitive, and spaces or special characters matter. If you do not know the password, look on a sticker on the back or bottom of your router, or log into your router's admin panel through a web browser on another device.

Update your WiFi driver on Windows or Mac

Your PC uses a piece of software called a driver to communicate with the WiFi hardware inside it. If that driver is outdated or corrupted, your PC may not connect even though the hardware works fine.

On Windows, 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 WiFi or wireless—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 for and install the latest version. Restart your PC when prompted.

On a Mac, click the Apple menu and select "System Settings". Go to "General" > "Software Update" and install any available updates. Mac drivers update through the operating system, not separately. Restart your Mac after the update finishes.

Check if the router is broadcasting the network name

Some routers have a setting that hides the network name from the list of available networks. If your network is hidden, you will not see it when you look for it, but you can still connect if you know the name and password.

On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks > Add a New Network. Select "Enter the network name and other information manually". Type your network name exactly as it appears, select the security type (usually WPA2 or WPA3), enter the password, and click "Next".

On a Mac, click the WiFi icon in the menu bar, scroll to the bottom of the network list, and select "Join Other Network". Type your network name and password and click "Join".

If you do not know whether your network is hidden, log into your router's admin panel. Open a web browser and type the router's IP address—usually 192.168.1.1 or 192.168.0.1—into the address bar. Log in with the admin username and password (often "admin" and "admin", or printed on the router). Look for a setting called "SSID Broadcast" or "Hide Network" and make sure it is enabled or turned on.

Restart your PC if nothing else works

A restart clears temporary memory problems and resets the connection process from the beginning. It sounds basic, but it solves a surprising number of connection issues.

Save any open work, then restart your PC normally through the Start menu or Apple menu. Do not use sleep mode or hibernate—a full restart is what matters. After your PC boots back up, try connecting to WiFi again.

If you still cannot connect after a restart, and you have already tried the steps above, the problem may be with the router itself, your internet provider's service, or the WiFi hardware inside your PC. At that point, contact your internet provider to check whether your service is working, or take your PC to a repair shop to have the WiFi hardware tested.

When to contact your internet provider or a repair technician

If your PC connects to other WiFi networks (at a coffee shop, library, or friend's house) but not to your home network, the problem is your router or your internet service, not your PC. Restart the router again, and if that does not work, contact your internet provider—they can check whether your service is active and whether the router needs to be replaced.

If your PC does not connect to any WiFi network, even after updating the driver and restarting, the WiFi hardware inside your PC may be failing. A repair technician can test the hardware and replace it if needed. This is more common on older PCs or ones that have been dropped or exposed to liquid.

If you see your network in the list but get an error message like "Cannot connect to this network" or "Incorrect password", try forgetting and reconnecting one more time. If the error persists, your router may need a full reset—this erases all settings and returns it to factory defaults. Check your router's manual for the reset button location, or contact your internet provider before resetting, because you will need to set up the network name and password again afterward.

Frequently Asked Questions

Why does my PC connect to WiFi but then disconnect after a few minutes?

This usually means the router is dropping the connection, not that your PC is failing to stay connected. Restart the router, and if the problem continues, move your PC closer to the router to rule out a weak signal. If it still disconnects, the router may be overheating—make sure it has space around it and is not in a hot closet or cabinet.

My password is correct, but Windows says it is wrong. What do I do?

Forget the network and reconnect, typing the password slowly and carefully. Make sure Caps Lock is not on. If you still get an error, reset the router to factory defaults and set up the network again with a new password. Write down the new password so you have it for next time.

Can a VPN or firewall block WiFi connections?

A VPN will not block WiFi itself, but some firewalls can interfere with connection attempts. If you have third-party antivirus or security software installed, try temporarily disabling it to see if the connection works. If it does, add your WiFi network to the software's trusted list or contact the software maker for help.

What if I see my network but it says "Can't connect to this network"?

This error usually means the password stored on your PC is wrong. Forget the network, restart the router, and reconnect with the password written down from the router itself. If the error continues, the router may need a restart or a full reset.

Does restarting the router erase my WiFi password?

No. A straightforward restart (unplugging and plugging back in) keeps all your settings. Only a factory reset erases the password and settings. You can restart the router as many times as you need without losing anything.
