The basic steps to connect

To connect your PC to WiFi, open the network settings on your computer, find the wireless network you want to join, and enter the password. The exact steps depend on whether you use Windows or Mac, but both take less than a minute once you have your router's password.

Your PC has a WiFi receiver built in (unless it is a very old desktop without one). When you turn on WiFi, your computer scans for available networks and displays them in a list. You select the network name, type the password, and your PC connects automatically from that point forward.

Key Takeaways

  • Windows PCs connect through Settings > Network & Internet > WiFi, while Mac computers use the WiFi icon in the menu bar at the top right of the screen.
  • You need the network name (SSID) and password, which are usually printed on your router or in the paperwork that came with it.
  • Once connected, your PC remembers that network and reconnects automatically when you are in range.
  • If your PC does not see any networks, WiFi may be turned off in hardware settings or your router may not be powered on.

Connecting on Windows 10 and Windows 11

Click the network icon in the bottom right corner of your taskbar (it looks like a WiFi symbol or a computer screen). A panel opens showing all available networks. Find your network name in the list and click it.

A box appears asking for the network password. Type it exactly as it appears on your router — passwords are case-sensitive, so uppercase and lowercase letters matter. Click Next or Connect. Windows will show a spinning circle while it connects, then display "Connected" next to your network name.

If you do not see your network in the list, make sure your router is powered on and WiFi is enabled. Some routers have a physical WiFi button you may need to press. If the button has a light next to it, that light should be on or blinking.

Connecting on Mac

Look at the top right corner of your screen for the WiFi icon (it looks like a fan or curved lines). Click it. A dropdown menu shows all available networks. Click the network you want to join.

A password box appears. Type your network password and click Join. Your Mac connects and the WiFi icon changes to show signal strength. Your Mac will remember this network and connect to it automatically the next time you are in range.

Finding your network password

Your router's password is usually printed on a sticker on the back or bottom of the device itself. Look for a label that says "WiFi Password", "Network Key", "Passphrase", or sometimes just "Password". The password may also be in the paperwork or manual that came with your router.

If you cannot find the password, you can reset your router to its factory settings, but this erases all your custom settings. A safer option is to contact your internet provider — they can tell you the default password or help you reset it. If you set up the router yourself and forgot the password, you will need to reset it using the small reset button on the device (usually requires holding it for 10 seconds).

What to do if your PC will not connect

If you enter the password and get an error message, the most common cause is typing the password wrong. Passwords are case-sensitive and spaces count. Try typing it again slowly, or copy and paste it if you can see it on the router label.

If the password is correct but your PC still will not connect, restart your router by unplugging it for 30 seconds and plugging it back in. While the router restarts, restart your PC as well. Once both are back on, try connecting again.

If your PC does not see any networks at all, WiFi may be turned off. On Windows, check that the WiFi toggle in Settings > Network & Internet is turned on. On Mac, click the WiFi icon and make sure "Turn WiFi On" is not showing (if it is, click it to turn WiFi on). You can also check if your PC has a physical WiFi button or switch — some laptops have one on the keyboard or the side of the device.

Understanding network names and passwords

The network name is called the SSID (Service Set Identifier). This is what you see in the list when you search for networks. Your router broadcasts this name so nearby devices can find it. By default, routers use a name like "NETGEAR-5G" or "TP-Link-Guest", but you can change it to anything you want through your router's settings.

The password (also called the passphrase or network key) is what protects your network from strangers connecting to it. Without the password, anyone nearby could use your internet. Passwords are usually at least 8 characters long and often include a mix of letters, numbers, and symbols.

Connecting to public WiFi networks

Coffee shops, libraries, and airports offer free public WiFi. These networks usually have no password — you just click the network name and you are connected. Some public networks require you to open a web browser first, which shows a login page or terms of service you must accept.

Public WiFi is less secure than your home network because anyone can see what you are doing. Avoid entering passwords, credit card numbers, or sensitive information on public WiFi. If you must do these things, use a VPN (Virtual Private Network), which encrypts your data so others cannot see it.

Frequently Asked Questions

Why does my PC keep disconnecting from WiFi?

This usually happens because your PC is too far from the router, or something is blocking the signal (thick walls, metal objects, or other electronics). Try moving closer to the router. If that fixes it, you may need to move your router to a more central location or buy a WiFi extender. If you are close to the router and still disconnecting, restart both your PC and router.

Can I connect to WiFi without knowing the password?

No, you need the password to connect to a secured network. If you do not know it, check the router itself for a sticker with the password, check your router's manual, or contact your internet provider. The only exception is open public networks, which have no password.

What is the difference between 2.4GHz and 5GHz WiFi?

These are two different frequency bands your router may broadcast. 2.4GHz has longer range but slower speeds; 5GHz is faster but does not travel as far. Many modern routers broadcast both at once under the same network name, and your PC automatically picks the best one. If your router shows separate networks for each band, choose 5GHz if you are close to the router, or 2.4GHz if you are far away.

Will connecting to WiFi slow down my internet?

WiFi is slightly slower than a wired connection (ethernet cable), but for most people the difference is not noticeable. If you need maximum speed for gaming or video editing, use an ethernet cable. For everyday browsing, email, and streaming, WiFi is fast enough.

Can I connect multiple devices to the same WiFi network?

Yes, your router can handle many devices at once — typically 20 to 50 depending on the router model. Each device needs the password to connect, but after that they all share the same network. The more devices connected, the slower each one may be, but for normal use you will not notice a difference.
