What "the internet is on" actually means
When you ask "is the internet on," you are really asking one of three different things, and the answer depends which one you mean. You might be asking whether your modem — the device that connects your home to your internet provider — has power and is receiving a signal. You might be asking whether your router — the device that broadcasts WiFi — is working. Or you might be asking whether you can actually reach websites and services, which is the only answer that really matters when you are trying to get something done.
These are not the same thing. Your modem can have power and your router can be broadcasting a signal you can connect to, but you still cannot load a webpage. Your WiFi can be on and working, but your phone might not be connected to it. The internet being "on" in the way that matters — the way that lets you do something — requires all three pieces working together.
Key Takeaways
- Your modem, router, and actual connection to websites are three separate things, and all three have to work for you to use the internet.
- A lit-up modem and router do not mean you can reach websites — you need to check by actually trying to load one.
- If your modem has no lights or they are all red, restart it by unplugging it for 30 seconds, then plugging it back in.
- If your router is on but you cannot connect to WiFi, restart the router the same way, or press its reset button if restarting does not work.
- If you can connect to WiFi but cannot load websites, the problem is usually with your internet provider's service, not your equipment.
How to check if your modem is working
Your modem is the box that connects directly to the cable or phone line coming into your home. It usually sits near where that line enters the wall. Look at the lights on the front of it. A working modem should have at least one light that is solid green or solid white — usually labeled "online," "internet," "link," or "status." If all the lights are off, the modem has no power. If the lights are red or blinking red, the modem is powered but not receiving a signal from your provider.
If the modem has no lights or they are red, unplug it from the power outlet for 30 seconds, then plug it back in. Wait two to three minutes for it to fully restart. The lights should go through a sequence of blinking and then settle into a solid green or white. If they do not, and you have waited a full three minutes, the modem itself may be broken or your provider's service may be down in your area. You can call your internet provider to ask whether they are experiencing an outage.
How to check if your router is working
Your router is usually a separate device that sits on a shelf or table, though some providers combine the modem and router into one box. The router broadcasts the WiFi signal that your phone, laptop, and other devices connect to. Like the modem, it should have lights on the front. A working router usually has a solid green or white light labeled "power" or "status," and often a separate light for WiFi that may be solid or blinking.
If your router has no lights, check that it is plugged in and the power switch is on. If it is plugged in and powered on but has no lights, try unplugging it for 30 seconds and plugging it back in. If the lights come on but are red, or if you can see the WiFi network name on your phone but cannot connect to it, restart the router the same way. If restarting does not fix it, look for a small reset button on the back of the router, press it with a pen or paperclip for 10 seconds, and wait for the lights to restart. Be aware that pressing the reset button will erase your WiFi password and network name, so you will have to set them up again.
How to actually test if you can use the internet
The only real test of whether the internet is on is whether you can reach a website. Open your web browser — Safari, Chrome, Firefox, or Edge — and try to go to a website you know well, like Google.com or BBC.com. If the page loads, your internet is working. If you get an error message like "cannot reach this page" or "no internet connection," then something is broken, even if your modem and router lights look fine.
If you cannot load a website, first check that you are actually connected to your WiFi. On your phone or laptop, look at the WiFi icon in the top corner or settings menu. It should show the name of your network and say "connected." If it says "not connected" or shows no networks, select your network name and enter your WiFi password. Then try loading a website again. If you are connected to WiFi but still cannot load websites, restart your modem and router as described above, wait three minutes, and try again.
What to do if the modem and router are on but websites will not load
If your modem has a solid green light, your router is on and broadcasting WiFi, you are connected to the WiFi, but you still cannot load any websites, the problem is almost certainly with your internet provider's service, not with your equipment. This is called an outage. You can check whether your provider is having problems by calling their customer service number — it is usually on your bill or on the back of your modem.
When you call, have your account number ready — it is also on your bill. Tell them you can connect to WiFi but cannot reach any websites. They can tell you whether service is down in your area and when it is expected to be restored. If service is down, there is nothing you can do except wait. If they say service is up, they may walk you through additional troubleshooting steps, or they may send a technician to check your equipment.
Understanding the lights on your modem and router
Different modems and routers use different light colors and labels, but the pattern is usually the same. A solid green or white light means that part is working. A blinking light usually means data is being sent or received — this is normal and you will see it when you are loading a webpage. A red light or no light means that part is not working. Some devices have separate lights for power, internet connection, and WiFi, so you need to check all of them.
If you are not sure what the lights mean on your specific modem or router, look at the label on the back or bottom of the device. It usually lists what each light represents. You can also search online for the model number — it is printed on the device — plus the word "manual" to find a guide that explains the lights. The manual will also tell you where the reset button is if you need to find it.
When to restart versus when to call your provider
Restart your modem and router if the lights are off, red, or if you cannot connect to WiFi even though the router is on. Unplug the modem first, wait 30 seconds, plug it back in, and wait three minutes. Then do the same with the router. This fixes most problems because it clears out temporary errors in the devices' memory. If restarting does not work after you have waited a full three minutes, try it one more time — sometimes devices need two restarts.
Call your internet provider if restarting does not fix the problem, if the modem light stays red after restarting, or if you can connect to WiFi but cannot load any websites. Have your account number ready and tell them exactly what you see — for example, "the modem light is red" or "I can see my WiFi network but cannot connect to it." They have tools to check your service from their end and can tell you whether the problem is on their side or yours.
Frequently Asked Questions
Why do the lights on my modem keep blinking?
Blinking lights usually mean data is being sent or received, which is normal. If the lights blink constantly even when you are not using the internet, restart the modem. If they keep blinking after restart, call your provider — there may be a problem with the connection.
Can I restart my modem and router at the same time?
You can, but it is better to restart the modem first, wait for it to fully restart (about three minutes), then restart the router. This way you know which device fixed the problem if one of them was the issue. If you restart both at once, you will be without internet for longer.
What does it mean if my WiFi network name does not show up on my phone?
It usually means your router is off or not working. Check that it is plugged in and powered on, and look for lights on the front. If there are no lights, restart it. If lights come on but your network still does not appear, try restarting again or pressing the reset button on the back.
Is it safe to press the reset button on my router?
Yes, it is safe, but it will erase your WiFi password and network name. You will have to set them up again from scratch. Only press it if restarting the router does not fix your problem, or if you have forgotten your WiFi password and need to start over.
How long should I wait after restarting before I know if it worked?
Wait at least three minutes. The modem and router need time to fully restart and reconnect to your provider's service. If you try to use the internet before three minutes have passed, it may not work even though the restart is still in progress.
