Why Your PC Won't Connect to WiFi — and How to Fix It

Start with the simplest fixes first

Most WiFi connection problems on a PC come down to three things: the WiFi is actually off, the password is wrong, or the router needs to restart. Before you assume something is broken, check whether airplane mode is on (look for a plane icon in your system tray or settings), whether you typed the network password correctly, and whether your router has power and shows lights on the front.

If your PC connected to this WiFi before and suddenly stopped, restart the router by unplugging it for 30 seconds, then plugging it back in. While it restarts, restart your PC as well. This clears temporary connection problems that build up over time and fixes the majority of WiFi issues without any other work.

Key Takeaways

Airplane mode, a wrong password, or a router that needs restarting causes most WiFi problems and takes less than five minutes to fix.
If your PC sees the network but cannot connect, the password is the first thing to check, followed by restarting both the router and your PC.
If your PC does not see the network at all, the WiFi adapter may be turned off in Device Manager or the router may not be broadcasting the network name.
Updating or reinstalling the WiFi driver solves connection problems that persist after restarting, especially after a Windows update.
If nothing works, a factory reset of the router or a call to your internet provider may be necessary, but this is rarely the first step.

Check whether your PC can see the network at all

Open the WiFi menu on your PC by clicking the network icon in the system tray (bottom right of your screen). If you see your network name in the list, your PC can see the router. If you do not see it, the problem is either that the router is not broadcasting the network name or your WiFi adapter is off.

To check the WiFi adapter, open Device Manager by right-clicking the Start button and selecting Device Manager. Look for "Network adapters" and expand it. Find the adapter with "Wireless" or "WiFi" in the name. If there is a down arrow or X on it, the adapter is disabled. Right-click it and select "Enable device." If there is no down arrow, the adapter is on and the problem is likely the router.

If the router is not broadcasting the network name, you will need to log into the router itself. Open a web browser and type 192.168.1.1 or 192.168.0.1 into the address bar. Log in with the username and password on the back of the router (often "admin" and "admin" or "admin" and the router's serial number). Look for a setting called "SSID" or "Network Name" and make sure it is not hidden or turned off.

Verify the password and reconnect

Click on your network name in the WiFi menu and select "Connect." When prompted, enter the WiFi password. The password is usually on a sticker on the back or bottom of the router. Type it exactly as it appears, paying attention to capital letters, numbers, and special characters—WiFi passwords are case-sensitive.

If you have changed the password since you last connected, use the new one. If you do not remember the password, you can reset it by logging into the router (using the 192.168.1.1 address above) and looking for a WiFi or Security section. You can also factory reset the router by holding the reset button on the back for 10 seconds, which returns the password to the default on the sticker.

Update or reinstall the WiFi driver

If your PC sees the network and the password is correct but the connection keeps dropping or fails to establish, the WiFi driver may be outdated or corrupted. A driver is the software that tells Windows how to talk to your WiFi adapter.

Open Device Manager again, find your WiFi adapter under "Network adapters," right-click it, and select "Update driver." Choose "Search automatically for updated driver software." Windows will search for a newer version online and install it if one is found. Restart your PC when prompted.

If updating does not work, right-click the adapter again and select "Uninstall device." Restart your PC. Windows will automatically reinstall the driver on startup. This clears out corrupted driver files and often fixes connection problems that started after a Windows update.

Check for interference and signal strength

WiFi signals travel through walls and air, but they can be blocked or weakened by physical objects and other wireless devices. Microwaves, cordless phones, baby monitors, and other WiFi networks all broadcast on the same frequencies and can interfere with your connection.

Move your router away from the microwave and other electronics, and move your PC closer to the router if possible. If your router is in a closet or cabinet, move it to an open space. If you live in an apartment or dense neighborhood, your router may be picking up interference from neighboring networks. You can check this by opening a WiFi analyzer app (search "WiFi analyzer" in the Microsoft Store) to see which channels nearby networks are using, then log into your router and switch to a less crowded channel.

Restart your PC in Safe Mode with Networking

If the driver update did not work, Safe Mode with Networking can help you figure out whether a third-party program is blocking the connection. In Safe Mode, Windows loads only the essential drivers and services, so if your WiFi works there, something else on your PC is the problem.

Restart your PC and press F8 repeatedly as it starts up (before the Windows logo appears). Select "Safe Mode with Networking" from the menu. Try to connect to WiFi. If it works in Safe Mode, a program you installed is interfering. Restart normally and uninstall recently installed security software, VPN apps, or network utilities one at a time, restarting after each one, until the connection works.

Reset the network settings or factory reset the router

If nothing above has worked, you can reset your PC's network settings, which clears out corrupted connection profiles. Open Settings, go to System, then Recovery. Click "Reset this PC" and choose "Keep my files." This removes all network profiles and forces Windows to rebuild them from scratch.

Alternatively, factory reset the router by holding the reset button on the back for 10 to 15 seconds until the lights blink. This returns the router to its original settings. You will need to set up the network name and password again using the setup wizard that appears when you first connect, or by logging into 192.168.1.1 with the default credentials on the sticker.

If the PC still cannot connect after a factory reset, the router itself may be failing, or there may be a problem with your internet service. Contact your internet provider to check whether the router is working correctly.

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 your PC. Restart the router and check whether it is overheating (feel the back—it should be warm but not hot). Move it to a location with better airflow. If it keeps dropping, update the router's firmware by logging into 192.168.1.1 and looking for a System or Administration section with a Firmware Update option.

My phone connects to the WiFi fine, but my PC does not. What is different?

Your phone and PC use different WiFi adapters and drivers, so a problem on one does not mean the other is broken. The issue is almost always the PC's WiFi driver or adapter. Update the driver in Device Manager, and if that does not work, uninstall and reinstall it by restarting your PC.

I see my network but it says "can't connect to this network" when I try. What does that mean?

The password is wrong, the router is blocking your PC's MAC address, or the driver is corrupted. First, double-check the password character by character. If that is correct, restart the router. If it still fails, update the WiFi driver in Device Manager.

Can a Windows update break my WiFi connection?

Yes. Windows updates sometimes install a driver that does not work with your adapter. Open Device Manager, right-click your WiFi adapter, and select "Update driver." If that does not help, uninstall the adapter and restart your PC to force Windows to reinstall the driver from before the update.

What if I need to call my internet provider—how do I know?

Call them if the router is powered on and showing lights, your PC can see the network and you have entered the correct password, but the connection fails or drops constantly even after restarting both devices and updating the driver. They can check whether the router is working and whether there is a problem on their end.
