What a hotspot does and why you might need one

A hotspot is a way to share your phone's or computer's internet connection with other devices nearby. When you turn on a hotspot, your device becomes a small wireless router — other phones, tablets, or laptops can connect to it the same way they would connect to home Wi-Fi. This is useful when you're away from home, when your home network goes down, or when you need to get a device online in a location without Wi-Fi.

The connection works through your phone's cellular data (the same data you use for calls and texts) or through your computer's existing internet. Other devices connecting to your hotspot will use that data, so if you have a limited data plan, watch how many devices connect and what they're doing — streaming video or downloading large files will burn through data quickly.

Creating a hotspot takes less than a minute once you know where to look. The steps differ slightly between iPhones, Android phones, Windows computers, and Macs, but the principle is the same on all of them.

Key Takeaways

  • On an iPhone, go to Settings > Personal Hotspot and toggle it on, then other devices will see it as a Wi-Fi network to join.
  • On Android, open Settings > Network and Internet > Hotspot and Tethering, tap Mobile Hotspot, and turn it on.
  • On Windows, go to Settings > Network and Internet > Mobile Hotspot, choose your internet source, and toggle it on.
  • On a Mac, open System Settings > General > Sharing, select Internet Sharing, choose your connection type, and check Wi-Fi Options to set a password.
  • All devices connecting to your hotspot will see it as a Wi-Fi network and will need the password you set or that your device creates automatically.

Creating a hotspot on an iPhone

Open the Settings app and tap Personal Hotspot near the top of the menu. If you don't see it, scroll down — it's usually between Bluetooth and VPN. Tap the toggle next to "Allow Others to Join" to turn it on. Your iPhone will now broadcast a Wi-Fi network that other devices can see.

By default, your hotspot uses your phone's name as the network name (the thing other devices see when they search for Wi-Fi). The password is generated automatically and shown on the same screen. Write it down or remember it — you'll need to give it to anyone connecting to your hotspot. If you want to change the password, you can't do it from the Personal Hotspot screen; instead, go to Settings > General > About and change your iPhone's name, which will change the hotspot name too. The password will stay the same unless you turn the hotspot off and back on.

Your iPhone will stay in hotspot mode until you turn it off manually. The battery will drain faster than normal because your phone is working harder, so plug it in if you're going to use it for more than an hour or so.

Creating a hotspot on an Android phone

Open Settings and look for Network and Internet or Connections — the exact name varies by manufacturer. Tap it, then look for Hotspot and Tethering or just Tethering. Tap Mobile Hotspot or Wi-Fi Hotspot. You'll see a toggle at the top — turn it on.

Android will create a network name and password automatically. Tap Hotspot Settings or the gear icon to see them and change them if you want. The network name can be anything you choose. The password should be at least 8 characters — if Android generated one that's too short or too straightforward, you can change it here. Once you've set it the way you want, go back and make sure the hotspot toggle is on.

Some Android phones let you choose whether the hotspot runs on 2.4 GHz or 5 GHz (or both). The 5 GHz band is faster but has shorter range; 2.4 GHz is slower but reaches farther. If you're not sure, leave it on the default. Like iPhones, Android hotspots drain battery faster, so charge your phone if you plan to use it for a while.

Creating a hotspot on a Windows computer

Open Settings and go to Network and Internet. On the left side, click Mobile Hotspot. At the top, you'll see "Share my internet connection with other devices." Before you turn it on, you need to tell Windows which connection to share.

Click the dropdown under "Internet connection" and choose the connection you want to share. If your computer is connected to Wi-Fi, you can share that connection. If it's connected by Ethernet cable, you can share that instead. Once you've chosen, toggle on "Mobile Hotspot" at the top. Windows will create a network name and password automatically and show them on the screen.

If you want to change the network name or password, click Edit under "Network name" or "Network password." You can make them anything you want — the password should be at least 8 characters. Once you've set them, toggle the hotspot back on if it turned off. Other devices will now see your computer as a Wi-Fi network they can join.

Creating a hotspot on a Mac

Open System Settings and click General on the left. Scroll down and click Sharing. In the list on the left, find Internet Sharing and click it. Before you turn it on, you need to tell your Mac which connection to share and how to share it.

At the top, click the dropdown next to "Share your connection from" and choose the connection your Mac is using — Wi-Fi if you're connected wirelessly, Ethernet if you're plugged in. Below that, check the box next to Wi-Fi to share the connection over Wi-Fi. Click Wi-Fi Options to set the network name and password. The network name is what other devices will see; the password should be at least 8 characters. Once you've set both, click OK.

Now click the checkbox next to "Internet Sharing" to turn it on. A dialog will appear asking if you're sure — click Start. Your Mac will now broadcast a Wi-Fi network with the name and password you set. Other devices can connect to it the same way they would connect to any other Wi-Fi network.

Connecting other devices to your hotspot

Once your hotspot is running, other devices will see it as a Wi-Fi network in their network list. On an iPhone or iPad, go to Settings > Wi-Fi and look for your hotspot's network name in the list. Tap it and enter the password. On an Android phone, open Settings > Network and Internet > Wi-Fi, look for the network name, tap it, and enter the password. On a Windows or Mac computer, click the Wi-Fi icon in the system tray or menu bar, find the network name, click it, and enter the password.

Once a device is connected, it will stay connected until you manually disconnect it or turn off the hotspot. If you're away from the device that's hosting the hotspot, the connection will drop — you can't use a hotspot from another room if the hosting device is out of range, just like regular Wi-Fi.

Troubleshooting when devices won't connect

If a device can see your hotspot but won't connect, the most common reason is a wrong password. Double-check the password on the device hosting the hotspot and make sure you're typing it correctly on the connecting device — passwords are case-sensitive, so "MyPassword" is different from "mypassword."

If the password is correct but the device still won't connect, try turning the hotspot off and back on. This resets the connection and often fixes temporary glitches. If that doesn't work, restart the device that's trying to connect. If you're still stuck, forget the network on the connecting device (go to its Wi-Fi settings, find the hotspot name, and tap "Forget"), then try connecting again and re-entering the password.

On older devices or devices far from the hotspot, connection can be slow or drop frequently. Move the hosting device closer, or if that's not possible, check whether your hotspot is set to 5 GHz (faster but shorter range) and switch it to 2.4 GHz if available.

Frequently Asked Questions

Does using a hotspot use my phone's data plan?

Yes. When other devices connect to your hotspot, they use your phone's cellular data the same way your phone does. If you have a limited data plan, watch what devices are doing — streaming video or downloading files will use data quickly. Check your data usage in your phone's settings to see how much you've used.

Can I use a hotspot if I don't have unlimited data?

You can, but you need to be careful. Each device using your hotspot counts against your data limit. If you have 5 GB per month and two devices are streaming video, you could run out in hours. Turn off the hotspot when you're not using it, and tell people connecting to it that they should avoid large downloads or streaming.

Why does my hotspot keep disconnecting?

The most common reason is that the hosting device went to sleep or locked. On phones, go to Settings and look for a screen timeout or sleep setting — set it to never sleep while the hotspot is on. On computers, disable sleep mode in your power settings. If it's still disconnecting, move the hosting device closer to the connecting devices, or restart both devices.

Can I password-protect my hotspot?

Yes, and you should. All hotspots create a password by default, but you can change it to something easier to remember. Go to the hotspot settings on the device hosting it and look for "Network Password" or "Wi-Fi Password." Make it at least 8 characters and something you won't forget, but don't use something obvious like your birthday.

What's the difference between a hotspot and tethering?

Hotspot and tethering are the same thing — they both mean sharing your phone's or computer's internet with other devices. Some phones use the word "hotspot," others use "tethering." The function is identical either way.
