The Basic Steps to Connect

To connect your computer to WiFi, you need to find the network name (called an SSID), select it from your available networks list, and enter the password. On Windows, this takes about one minute. On Mac, the process is nearly identical. The connection stays saved after the first time, so your computer will reconnect automatically when you're in range.

Your computer has a WiFi antenna built in—you don't need to buy anything extra. The wireless signal comes from a router, which is the device your internet provider installed or that you bought separately. If you don't see any networks listed, your WiFi is either turned off on your computer or the router is not powered on.

Key Takeaways

  • Open your network settings, find the WiFi icon in the system tray (Windows) or menu bar (Mac), and click it to see available networks.
  • Select your network name from the list, enter the password exactly as it appears (passwords are case-sensitive), and click Connect.
  • Once connected, your computer remembers that network and will join it automatically the next time you're in range.
  • If you don't see your network listed, restart your router by unplugging it for 30 seconds, then plugging it back in.
  • The password is usually printed on a sticker on your router or in the paperwork that came with it.

Connecting on Windows 10 and Windows 11

Look for the WiFi icon in the bottom right corner of your screen, in the system tray next to the clock. It looks like a fan or curved lines. Click it once. A panel will slide out showing all the WiFi networks your computer can detect.

Find your network name in that list. If you don't know your network name, check the sticker on the bottom or back of your router—it's usually labeled "SSID" or "Network Name." Click on your network name. A box will appear asking for the password. Type the password carefully, letter by letter. Passwords are case-sensitive, meaning capital letters are different from lowercase letters. The password is also on the router sticker, usually labeled "Password," "WiFi Password," or "Key."

Click the "Connect" button. Windows will try to join the network. This usually takes 10 to 20 seconds. Once it succeeds, the WiFi icon will show a filled-in signal indicator instead of an empty one. Your computer is now connected and will stay connected as long as you're in range of the router.

Connecting on Mac

Look for the WiFi icon in the top right corner of your menu bar—it looks like a fan or curved lines. Click it. A dropdown menu will show all available networks.

Click your network name. A dialog box will ask for the password. Type it exactly as it appears on your router sticker, paying attention to uppercase and lowercase letters. Click "Join." Your Mac will connect within 10 to 20 seconds. The WiFi icon will fill in with a solid signal indicator when you're connected.

What to Do If You Can't Find Your Network

If your network name doesn't appear in the list, the router may not be broadcasting it, or it may be turned off. First, check that your router is plugged in and powered on. Look for a light on the front or back—most routers have a power light that glows when they're running.

If the router is on, restart it by unplugging the power cable for 30 seconds, then plugging it back in. Wait two to three minutes for it to fully restart. The lights on the front will blink as it boots up. Once the lights settle into a steady pattern, try searching for your network again.

If you still don't see it, your router may have WiFi disabled. Check whether there's a physical WiFi button on the router—some routers have a small button you press to turn WiFi on and off. Press it if you find one. If there's no button, restart your computer and try again. Sometimes a computer's WiFi adapter needs to be reset.

Entering the Password Correctly

The most common reason a connection fails is a password typed incorrectly. WiFi passwords are case-sensitive, which means that "MyPassword" is not the same as "mypassword." Check the sticker on your router carefully. If the password contains the number zero, make sure it's not the letter O. If it contains the number one, make sure it's not the letter l (lowercase L).

If you're not sure what the password is, you can usually find it in your router's settings. Open a web browser and type the router's IP address into the address bar—this is usually 192.168.1.1 or 192.168.0.1, and it's printed on the router sticker. You'll be asked to log in with a username and password, which are also on the sticker. Once logged in, look for a WiFi or Wireless settings page where the password is displayed.

Staying Connected and Reconnecting

After you connect once, your computer saves that network and password. The next time you're in range, your computer will join automatically without asking for the password again. You don't have to do anything—it just happens in the background.

If your connection drops, your computer will try to reconnect on its own. If it doesn't, open the WiFi menu again and click your network name. Sometimes you'll need to enter the password again if your computer forgot it. This can happen after a major system update or if you've reset your network settings.

If you move to a new location and want to forget a network so your computer stops trying to connect to it, right-click the network name in the WiFi list (Windows) or click the information icon next to it (Mac) and select "Forget." This removes the saved password and connection history.

Checking Your Connection Speed and Strength

Once connected, you can see how strong your signal is by looking at the WiFi icon. More filled-in bars mean a stronger signal. If you're far from the router or there are walls between you and it, the signal will be weaker. Moving closer to the router usually improves the connection.

To see more details about your connection on Windows, right-click the WiFi icon and select "Open Network and Internet settings." Scroll down and click "Advanced network options," then look for "WiFi" in the list. Click it to see your current network name, connection speed, and signal strength.

On Mac, hold down the Option key and click the WiFi icon. A menu will show your network name, signal strength, and the channel your router is using. This information is mostly for reference—you don't need to change anything unless you're troubleshooting a connection problem.

Frequently Asked Questions

Why does my computer keep disconnecting from WiFi?

Disconnections usually happen because you're too far from the router, there's interference from other devices, or your router needs to be restarted. Move closer to the router and try again. If the problem continues, restart your router by unplugging it for 30 seconds. If disconnections keep happening, your router may be failing and may need to be replaced.

Can I change my WiFi password after I connect?

Yes. Log into your router's settings by typing its IP address (usually 192.168.1.1) into a web browser. Use the username and password on the router sticker. Look for WiFi settings or Wireless settings and change the password there. Your computer will ask for the new password the next time it tries to connect.

What if I forgot my WiFi password?

Check the sticker on your router first—the password is usually printed there. If the sticker is missing or worn, you can reset the router to its factory settings by holding down a small reset button on the back for 10 seconds. This erases all your settings, and you'll need to set up the router again from scratch using the instructions that came with it.

Do I need to connect every time I turn on my computer?

No. Once you connect and your computer saves the network, it will join automatically whenever you turn it on and it's in range of the router. You only need to enter the password once, unless you change the password or reset your network settings.

Can I connect multiple computers to the same WiFi network?

Yes. Every computer, phone, and tablet in your home can connect to the same network using the same password. There's no limit to how many devices can connect, though too many devices using the network at once may slow down the connection for everyone.
