Check your connection status in seconds

The fastest way to know if your device is connected to the internet is to look at the network icon in your system tray or menu bar. On Windows, this is the small icon in the bottom right corner of your screen. On Mac, it's in the top right. On phones and tablets, it's at the top of the screen. A filled-in icon or a checkmark means you're connected; a crossed-out or empty icon means you're not.

If the icon shows you're connected but nothing is loading, your device may be linked to a network that doesn't actually reach the internet. This happens often with public WiFi that requires you to log in first, or with home networks where the router has lost its connection to your internet service provider.

Key Takeaways

  • The network icon in your system tray (Windows) or menu bar (Mac) shows your connection status at a glance.
  • Being connected to a network is not the same as being connected to the internet — you may need to log in or troubleshoot your router.
  • Opening a website or using a speed test tells you whether data can actually reach you, not just whether you're linked to a network.
  • On phones, airplane mode turns off all wireless connections; if it's on, you won't connect to anything.
  • Restarting your router and device fixes most connection problems and takes less than two minutes.

Test your connection by opening a website

The most reliable test is to open a web browser and try to load a simple website. Google.com, Wikipedia.org, or your email provider all work. If the page loads, you have an active internet connection. If you see an error message like "No internet" or "Cannot reach server," you don't.

This test is better than just checking the network icon because it confirms that data can actually flow between your device and the wider internet. You might be connected to your home WiFi but unable to reach the internet if your router isn't working properly or your internet service is down.

Run a speed test to measure your connection strength

If you want to know not just whether you're connected, but how fast your connection is, use a speed test website. Speedtest.net and Fast.com are both free and take about one minute to run. They measure how quickly data travels to and from your device.

A speed test tells you whether your connection is fast enough for what you're trying to do. Video streaming usually needs at least 5 Mbps. Video calls need about 2.5 Mbps. Browsing and email work on much slower connections. If your speed test shows you're getting far less than what your internet plan promises, contact your internet service provider — something may be wrong with your connection.

Check your WiFi or cellular connection on phones and tablets

On iPhones and iPads, swipe down from the top right corner to open Control Center. Look for the WiFi symbol. If it's filled in, you're connected to WiFi. If it's crossed out or missing, you're not. Next to it, look for the cellular bars — if they're filled in, cellular data is available.

On Android phones, swipe down twice from the top to open Quick Settings. You'll see WiFi and mobile data icons. A filled WiFi symbol means you're connected to WiFi. Bars next to the mobile data icon show your cellular signal strength. If airplane mode is turned on (it looks like a plane), all wireless connections are off — turn it off to reconnect.

If you're connected to WiFi but nothing loads, try opening a website to confirm the WiFi actually reaches the internet. Many public networks require you to open a browser and log in or accept terms before they let data through.

Restart your router and device to restore a lost connection

If your device shows it's connected to your network but you can't reach the internet, restart your router. Unplug it from power, wait 30 seconds, and plug it back in. Wait another two minutes for it to fully restart. Then try loading a website again.

If that doesn't work, restart your device. Power it off completely, wait 10 seconds, and turn it back on. Most connection problems — especially temporary ones — are fixed by restarting. If restarting doesn't help and your router's lights show it's working normally, contact your internet service provider to check whether the problem is on their end.

Understand the difference between network and internet connection

A network connection means your device is linked to a WiFi network or has cellular signal. A internet connection means that network is actually connected to the wider internet. You can have one without the other.

For example, you might connect to your home WiFi network, but if your router's internet cable is unplugged, you're connected to the network but not the internet. Or you might connect to a public WiFi at a coffee shop that requires you to log in through a browser first — until you do, you're on the network but can't reach most websites.

The network icon tells you about the network. A website test tells you about the internet. If they disagree, the website test is the accurate one.

Troubleshoot when you can't connect at all

If your device won't connect to any network, start with the obvious: is airplane mode on? On phones and tablets, swipe down to check Quick Settings or Control Center. On Windows, check the network icon in the system tray. On Mac, check the WiFi icon in the menu bar. If airplane mode is on, turn it off.

Next, make sure the network you're trying to connect to actually exists. On your device, look at the list of available networks. If you don't see your home WiFi network listed, your router may be off or too far away. Move closer to the router and try again. If you still don't see it, restart the router.

If you're trying to connect to a public network and it's not working, ask the business for the correct network name and password. Many places have multiple networks, and you might be trying to connect to the wrong one.

Frequently Asked Questions

What does the WiFi symbol with an exclamation mark mean?

It means your device is connected to the WiFi network but the network doesn't have internet access. You're on the network but can't reach websites or online services. Try restarting your router, or if you're on public WiFi, look for a login page that appears when you open a browser.

Can I have internet without WiFi?

Yes. Phones and tablets with cellular plans can use mobile data instead of WiFi. Computers can use an ethernet cable plugged directly into a modem or router. Both methods connect you to the internet without WiFi.

Why does my device say it's connected but nothing loads?

Your device is connected to the network but the network isn't connected to the internet. Restart your router by unplugging it for 30 seconds. If that doesn't work, the problem may be with your internet service provider's connection, not your device.

How do I know if my internet is down or if it's just my device?

Try connecting a different device to the same network. If the second device also can't reach the internet, your network or internet service is down. If only one device has the problem, restart that device or move it closer to your router.

What's a good internet speed?

It depends on what you're doing. Browsing and email work on 1 Mbps. Video calls need about 2.5 Mbps. Streaming video needs at least 5 Mbps. If you're paying for a certain speed, run a speed test to see if you're getting what you're paying for.
