The basic steps to join a Wi-Fi network

To connect to your home Wi-Fi, open the Wi-Fi settings on your device, find your network name in the list, select it, and enter your password. On Windows, click the network icon in the bottom right corner of your screen. On Mac, click the Wi-Fi icon in the top right. On phones and tablets, go to Settings, then Wi-Fi, and look for your network name — usually something your internet provider set up or a name you chose yourself.

Your network name (called the SSID) appears as a broadcast signal that nearby devices can see. Once you select it, the device will ask for your Wi-Fi password. This is the password you created when you set up your router, or the default one that came with it. After you enter the password correctly, your device connects and you can use the internet.

Key Takeaways

  • Your Wi-Fi network name and password are usually on a sticker attached to your router, or in the paperwork your internet provider sent you.
  • Each device stores the password after you enter it once, so you only have to type it in the first time you connect.
  • If you forget your password, you can reset your router to factory settings, but this erases all your custom settings and requires you to set it up again from the beginning.
  • Some devices may show a weak signal even when you are close to the router — moving the router to a central location or away from metal objects and microwaves can improve the connection.

Where to find your network name and password

Your router has a sticker on the bottom or back that lists the default network name and password. If you changed these after setup, you will need to remember what you changed them to. Write down both pieces of information and keep them somewhere safe — you will need the password every time you connect a new device.

If your internet provider set up the router for you, they may have given you a card or printed sheet with this information. Check any paperwork that came with your router or in the box your internet service arrived in. If you cannot find it, you can log into your router's settings page (usually by typing 192.168.1.1 or 192.168.0.1 into a web browser) and look for the Wi-Fi settings there, though this requires knowing your router's admin password.

What to do if your password is wrong

If you enter a password and the device says it is incorrect, first check that you are typing it exactly as it appears — passwords are case-sensitive, meaning uppercase and lowercase letters are different. Look at the sticker on your router again and make sure you have not mixed up numbers that look similar, like 0 and O or 1 and l.

If you are certain the password is correct but the device still will not connect, try "forgetting" the network on that device and connecting again. On Windows, go to Settings > Network > Wi-Fi > Manage Known Networks, find your network, and click Forget. On Mac, go to System Preferences > Network > Wi-Fi > Advanced, select your network, and click the minus button. On phones, go to Settings > Wi-Fi, tap the network name, and choose Forget. Then try connecting again and re-enter the password.

Why your device connects but has no internet

Sometimes a device shows as connected to Wi-Fi but cannot actually reach the internet. This usually means your router itself has lost its connection to your internet provider. Restart your router by unplugging it for 30 seconds, then plugging it back in. Wait two to three minutes for it to fully restart — you will see lights on the front blink and then settle into a steady pattern.

If restarting does not fix it, check that the cable from your wall or modem is firmly plugged into the port labeled "Internet," "WAN," or "Uplink" on your router. If you have a separate modem (a device between the wall and your router), restart that first, wait for it to fully boot, then restart the router. If the modem has a light that shows internet connection status, make sure that light is on or green before you restart the router.

Improving a weak or slow connection

Wi-Fi signal gets weaker the farther you are from the router and when it has to pass through walls, metal, or water. If you notice slow speeds or frequent disconnections, try moving your router to a more central location in your home — ideally elevated and away from the floor. Keep it away from microwaves, cordless phones, and baby monitors, which broadcast on the same frequency and can cause interference.

If moving the router is not possible, you can buy a Wi-Fi extender or mesh system to expand coverage. A Wi-Fi extender picks up your existing signal and rebroadcasts it to reach farther. A mesh system replaces your router with multiple smaller units that work together to cover your whole home. Both cost money, so try repositioning your router first to see if that solves the problem.

Connecting multiple devices to the same network

Your home Wi-Fi network can support many devices at once — typically 20 to 50 depending on your router model and internet speed. Each device connects using the same network name and password. Once a device has connected once, it will automatically reconnect whenever it is in range, so you do not have to re-enter the password every time.

If you have so many devices that some are dropping off the network, the issue is usually not the number of devices but the internet speed your provider gives you. Too many devices streaming video or downloading large files at the same time can slow everything down. Restart your router to clear out old connections, or check your internet plan to see if you need a faster speed.

Resetting your router if you forget the password

If you have forgotten your Wi-Fi password and cannot find it anywhere, you can reset your router to factory settings. Look for a small reset button (usually recessed) on the back or bottom of the router. Press and hold it for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart.

After the reset, your network name and password will go back to the defaults printed on the sticker. You can then log in with those credentials and set up a new password. Keep in mind that resetting also erases any other settings you customized, such as parental controls or port forwarding. Write down your new password somewhere safe after you set it.

Frequently Asked Questions

Why does my device say "connected, no internet"?

Your device is talking to the router, but the router has lost its connection to your internet provider. Restart the router by unplugging it for 30 seconds. If you have a modem, restart that first, wait for it to fully boot, then restart the router. Check that all cables are firmly plugged in.

Can I change my Wi-Fi password?

Yes. Log into your router's settings page by typing 192.168.1.1 or 192.168.0.1 into a web browser. You will need your router's admin username and password (usually "admin" and "admin" or "admin" and blank, unless you changed them). Look for Wi-Fi settings or Wireless settings and change the password there. All your devices will need to reconnect using the new password.

Is it safe to use the default password that came on the sticker?

The default password is better than nothing, but changing it to something only you know is safer. Default passwords are printed on thousands of routers, so anyone with the same router model could potentially guess yours. Change it to something unique after you set up your router.

Why does my phone keep disconnecting from Wi-Fi?

This usually happens when your phone is far from the router or when the signal is weak. Try moving closer or repositioning the router. Some phones also disconnect to save battery when they are not actively using the internet. Check your phone's Wi-Fi settings to see if there is a battery-saving option that disconnects Wi-Fi automatically.

Do I need to restart my router regularly?

Restarting once a month can help clear out old connections and improve performance, but it is not necessary unless you are having problems. If your connection is stable, you do not need to restart it.
