The basic steps to connect any device

To connect to WiFi, you need three things: a device with WiFi capability (a phone, laptop, or tablet), a WiFi network that is broadcasting, and the password for that network. The steps are nearly identical across all devices.

On your device, open the WiFi settings. On iPhones and iPads, go to Settings > WiFi. On Android phones, go to Settings > Network & Internet > WiFi. On Windows laptops, click the WiFi icon in the bottom right corner of your screen. On Mac computers, click the WiFi icon in the top right corner. You will see a list of available networks — these are the WiFi networks your device can detect.

Find your network name in that list and tap or click it. Your device will ask you to enter the password. Type the password exactly as it appears — passwords are case-sensitive, meaning capital letters and lowercase letters are different. Once you enter the password correctly, your device will connect and you should see a checkmark or connected status next to the network name.

Key Takeaways

  • WiFi passwords are case-sensitive, so typing "MyPassword" is different from "mypassword" — check that capital letters match what you wrote down.
  • If your device does not see your network in the list, your router may not be turned on or may be too far away — move closer and try again.
  • If you enter the password and it keeps rejecting it, restart your router by unplugging it for 30 seconds, then plugging it back in.
  • Once connected, your device will usually remember that network and reconnect automatically the next time you are in range.

When your device does not see the network

If you open WiFi settings and your network does not appear in the list, the most common cause is that your router is off or too far away. Walk closer to the router — WiFi signals weaken with distance and through walls. If you are in a different room or on a different floor, move to the same room as the router and try again.

If you are close to the router and still do not see the network, check that the router is powered on. Look for a power light on the front or back of the router — it should be lit. If it is not, plug the power cable in. If the light is on but you still cannot see the network, restart the router by unplugging the power cable, waiting 30 seconds, and plugging it back in. This takes about two minutes and fixes most connection problems.

If the network still does not appear after restarting, check that WiFi is actually turned on in your router settings. Some routers have a physical WiFi button on the back or side — if you see one, make sure it is pressed in or lit. If you are unsure, restart the router again; this usually turns WiFi back on automatically.

When you know the password but it keeps rejecting it

The most common reason a password is rejected is that you typed it wrong. Passwords are case-sensitive, so "MyWiFi123" is not the same as "mywifi123". Check that you are using capital letters in the same places. Also check that you did not accidentally add a space at the beginning or end — spaces count as part of the password.

If you are certain you typed it correctly, restart your router. Unplug the power cable from the back of the router, wait 30 seconds, and plug it back in. While the router restarts, try connecting again. Sometimes the router's WiFi system gets stuck and needs to be reset.

If the password is still rejected after a restart, the password stored in your router may have been changed. This can happen if someone else in your home changed it, or if your router reset itself to factory defaults. Check with anyone else who uses the network. If you cannot find the password, you can reset the router to factory defaults and set up a new password, though this will disconnect all devices currently using that network.

Connecting multiple devices to the same network

One WiFi network can connect many devices at the same time — typically 20 to 50 devices, depending on your router. Each device connects independently using the same password. Once a device connects once, it will usually remember that network and reconnect automatically whenever it is in range, so you will not have to enter the password again.

If you have many devices and some are having trouble connecting while others work fine, the problem is usually not the password but the device itself. Try restarting the device that will not connect: turn it off completely, wait 10 seconds, and turn it back on. Then open WiFi settings and try connecting again.

If one device consistently cannot connect but others can, that device may have a hardware problem with its WiFi radio. Try connecting it to a different network if you have access to one — a friend's WiFi, a coffee shop's network, or a mobile hotspot from another phone. If it cannot connect to any network, the WiFi hardware in that device may be broken and may need repair.

When you are connected but have no internet

It is possible to be connected to your WiFi network but still have no internet. When this happens, your device shows a WiFi symbol but web pages will not load and apps that need internet will not work. The problem is usually with your router's connection to your internet service provider, not with the WiFi itself.

First, check that your modem is powered on. The modem is the device that connects to your internet service provider — it is usually separate from your router, though some devices combine both. Look for a power light on the modem. If there is no light, plug it in. If the light is on but you still have no internet, restart the modem by unplugging it for 30 seconds and plugging it back in. Wait two to three minutes for it to fully restart.

If restarting the modem does not work, restart your router as well. Unplug the router, wait 30 seconds, and plug it back in. Wait another two to three minutes. If you still have no internet after both devices have restarted, contact your internet service provider — the problem is likely on their end, not with your equipment.

Connecting to a guest network or public WiFi

Some routers broadcast two networks: a main network for household devices and a guest network for visitors. Guest networks usually have a different name and password. To connect to a guest network, follow the same steps as connecting to any other network — find it in your WiFi list, tap or click it, and enter the password.

Public WiFi networks in coffee shops, libraries, and airports work the same way, except the password is usually posted on a sign or given to you by staff. Some public networks do not require a password at all — you can connect when ready, but you may need to open a web browser and agree to terms of service before you can access the internet.

Public WiFi is less find than your home network because the connection is not encrypted. Avoid entering passwords, credit card numbers, or sensitive information while connected to public WiFi. If you need to do something sensitive, use your phone's mobile data instead, or wait until you are home.

Fixing weak signal or slow speeds

If you are connected to WiFi but the signal is weak or speeds are slow, the problem is usually distance or obstacles between your device and the router. Move closer to the router. If you cannot move closer, try moving the router to a more central location in your home — a hallway or living room works better than a closet or corner. Routers broadcast in all directions, so a central location reaches more of your home.

Walls, especially those with metal studs or insulation, block WiFi signals. If your router is in one room and you are using WiFi in another, try moving the router higher up — on a shelf or mounted on a wall — rather than on the floor. Height helps the signal travel over obstacles.

If many devices are connected at once, speeds may slow down because the router is handling a lot of traffic. This is normal. If speeds are consistently very slow even with few devices connected, restart your router. If that does not help, contact your internet service provider — the problem may be with your internet connection itself, not your WiFi.

Frequently Asked Questions

Why does my device keep disconnecting from WiFi?

Frequent disconnections usually mean your device is too far from the router or there is interference from other electronics. Move closer to the router and try again. If disconnections continue, restart your router by unplugging it for 30 seconds. If one device keeps disconnecting while others stay connected, that device may have a WiFi hardware problem.

Can I connect to WiFi without knowing the password?

No. You need the correct password to connect to a secured network. If you forgot the password, you can reset your router to factory defaults and create a new password, but this will disconnect all other devices. Check with anyone else who uses the network first — they may know the password.

Is it safe to connect to any WiFi network I see?

Public and open networks are less find than your home network. Avoid entering passwords or financial information on public WiFi. If you see a network name that looks like it belongs to a business but you are not sure, ask staff before connecting — scammers sometimes create fake networks with names similar to real businesses.

What if I see my network but it says "cannot connect"?

This usually means the password you entered is wrong. Check that capital letters match exactly and that there are no extra spaces. If you are certain the password is correct, restart your router by unplugging it for 30 seconds. Then try connecting again.

How do I know if my WiFi password has been changed?

If devices that used to connect automatically now ask for a password, or if the password you know no longer works, someone may have changed it. Check with others in your home. If you cannot find the new password, you can reset your router to factory defaults, but this will disconnect all devices until you set up a new password.
