What "internet working" actually means

Your internet works if data can move between your device and the wider internet. That sounds simple, but there are actually three separate things that need to happen: your device needs to connect to your router or modem, your router needs to connect to your internet service provider's network, and that network needs to reach the destination you're trying to reach. A problem at any of these three points will feel like "the internet is down," even though only one piece is broken.

Most of the time when you think your internet isn't working, it's actually just one of these connections that's failed. Knowing which one is broken tells you what to fix — and whether you need to call your provider or just restart something yourself.

Key Takeaways

  • Your device connects to your router, your router connects to your modem, and your modem connects to your internet service provider — a break at any point stops everything.
  • Check the lights on your modem and router first: no lights usually means no power, and red lights usually mean no connection to your provider.
  • If your device shows it's connected to the router but nothing loads, the problem is between your modem and your provider, not your device.
  • Restart your modem by unplugging it for 30 seconds, then your router, then wait two minutes before testing — this fixes most connection problems.
  • If restarting doesn't work and your modem lights show red or no connection, contact your internet service provider to report an outage.

Check the lights on your modem and router first

The lights on these devices tell you where the problem is. Your modem is the box that connects to the cable or phone line coming into your home — it's usually provided by your internet service provider. Your router is the separate device that broadcasts WiFi, or it may be built into the modem as one unit.

Look for a light labeled "Internet," "Online," "WAN," or "Connection." If that light is off or red, your modem is not connected to your provider's network. If it's green or blue, that connection is working. A light labeled "Power" should be on; if it's off, the device isn't getting electricity. Lights labeled "WiFi" or "Wireless" show whether your router is broadcasting — if those are off, WiFi devices won't see the network, but wired devices plugged into the router may still work.

Write down what you see: which lights are on, which are off, and what color they are. This information is what your provider will ask for if you need to call them.

Test whether your device is connected to the router

On a Windows computer, open Settings, go to Network & Internet, and look for your WiFi network name in the list. If it shows "Connected," your device is talking to the router. On a Mac, click the WiFi icon in the top right and look for a checkmark next to your network name. On a phone or tablet, go to Settings and look for your network name with a checkmark or "Connected" label.

If your device shows it's connected to the router but nothing loads when you try to visit a website, the problem is not between your device and the router — it's between the modem and your provider. This is important because it tells you the issue is not on your side of the connection.

If your device doesn't see the router at all, or shows "No Internet Connection" even though it's connected, try moving closer to the router. If that fixes it, you have a WiFi range problem, not an internet outage. If it doesn't help, move to the next step.

Restart your modem and router in the right order

Most internet problems go away after a restart. The order matters: restart the modem first, then the router, because the router needs the modem to be working before it can reconnect.

Unplug the modem from power and wait 30 seconds. Plug it back in and wait for the lights to stabilize — usually two to three minutes. Then unplug the router, wait 30 seconds, and plug it back in. Wait another two minutes before testing. Don't skip the waiting time; the devices need time to fully restart and reconnect to each other and your provider.

After the restart, check the lights again. If the Internet or Connection light is now green or blue, try loading a website. If it works, the problem is solved. If the light is still red or off, or if nothing loads, move to the next step.

Test your connection with a simple website

Sometimes a website is down on the other end, not your internet. To tell the difference, try visiting a very basic website that almost never goes down. Google.com is a good choice because it's simple and reliable. If Google loads, your internet is working — the problem is with the website you were trying to reach.

If Google doesn't load either, try opening a new browser tab and typing a different address, like example.com. If multiple websites don't load, your internet connection is the problem. If one website loads but others don't, the issue is with those specific websites, not your connection.

You can also test your connection speed and stability by visiting speedtest.net. This will show you whether data is moving at the speed your provider promised and whether the connection is stable. Write down the results if you need to call your provider.

When to contact your internet service provider

Contact your provider if the Internet or Connection light on your modem is red or off after you've restarted both devices and waited the full time. Also contact them if the light is green but nothing loads, and you've tested multiple websites. Have ready: the color and status of the lights on your modem, what you see when you try to load a website, and the results from speedtest.net if you ran it.

Your provider can see from their end whether there's an outage in your area, whether your modem is connecting to their network, and whether data is flowing correctly. They may ask you to restart again while they watch the connection on their side, or they may send a technician. If there's a widespread outage, they'll tell you when service is expected to return.

Before you call, check your provider's website or social media to see if they've already posted about an outage in your area. Many providers have a status page you can visit without internet — you can access it on your phone using mobile data.

Wired vs. WiFi — which one to test first

If you have both a wired connection (a cable plugged directly into your router or modem) and WiFi, test the wired connection first. Plug a computer directly into the router with an ethernet cable. If that works but WiFi doesn't, the problem is your WiFi, not your internet connection. If the wired connection doesn't work either, the problem is your modem or provider.

WiFi problems are usually easier to fix than modem problems: move closer to the router, restart the router alone, or check whether other WiFi networks are interfering. Modem problems usually require a provider call. Testing wired first tells you which category you're in.

Frequently Asked Questions

What does it mean when my modem light is blinking?

Blinking usually means the device is working but actively sending or receiving data. A steady light means the connection is stable. A blinking light that never stops or a light that blinks very slowly might mean the connection is unstable or the device is having trouble. Try restarting if the blinking doesn't settle into a steady pattern after a few minutes.

Can I test my internet without a computer?

Yes. Use your phone on WiFi and try loading a website or opening an app that needs internet. If your phone works but your computer doesn't, the problem is your computer or its connection to the router, not your internet. If nothing works on any device, the problem is your modem or provider.

Why do I need to wait 30 seconds when restarting?

The device needs time to fully power down and clear its memory. Unplugging for less than 30 seconds sometimes leaves the device in a confused state. Thirty seconds is the standard wait time used by technicians and usually solves the problem.

Is my internet slow or is it broken?

Broken means nothing loads at all. Slow means things load but take a long time. If websites load, your internet is working — it's just slow. Run speedtest.net to see your actual speed and compare it to what your provider promised. If you're getting much less, contact your provider.

What if restarting doesn't fix it and my provider says there's no outage?

Ask your provider to check whether your modem is connecting to their network and whether data is flowing. If the modem isn't connecting, it may need to be replaced. If data is flowing but you still can't reach websites, the problem may be your device's settings or a problem between your router and modem — your provider can walk you through checking these.
