What "the internet is working" really means
When you ask "is the internet working," you are usually asking one of three different things, and the answer depends on which one. Your modem — the box that connects to your wall jack — might be powered on and lit up, but your router — the device that broadcasts WiFi — might be offline. Your router might be broadcasting a signal you can see and connect to, but data might not actually be moving. Or your connection might be moving data fine, but the website you want to visit might be down on their end.
Most people mean "can I browse the web right now," which is the hardest version to troubleshoot because it involves your equipment, your provider's equipment, and someone else's server all at once. This guide walks you through what each piece does and how to figure out which one is actually broken.
Key Takeaways
- Your modem and router are two separate devices, and one can be working while the other is not.
- A lit-up modem does not mean data is moving — you need to check whether you can reach your router and whether your router can reach the internet.
- If one website will not load but others do, the problem is on that website's end, not yours.
- Restarting your modem and router in the right order — modem first, then router — fixes most connection problems.
- Your internet provider's status page will tell you if there is an outage in your area before you spend time troubleshooting.
The difference between your modem and your router
Your modem is the device that talks to your internet provider. It usually sits near where the cable or fiber line enters your home. When the modem is working, you will see lights on the front — typically a power light, an internet light, and lights for each device connected to it. A solid green or blue light usually means that part is working; a red light or no light means it is not.
Your router is the device that takes the internet from the modem and broadcasts it as WiFi to your phone, laptop, and other devices. It is often a separate box, though some providers give you a combined modem-router unit. Even if your modem has a solid green light, your router could be offline or broadcasting a weak signal.
This matters because when something goes wrong, you need to know which device to restart. If your modem is fine but your router is frozen, restarting the modem will not help.
How to check if data is actually moving
A lit-up modem does not prove data is moving. To test whether your connection is actually working, try these steps in order:
- Open a web browser on your phone or computer and try to load a straightforward website like Google.com or BBC.com. If the page loads, your internet is working — you can stop here.
- If the page does not load, check whether you are connected to your WiFi. On your phone, go to Settings and look for WiFi. You should see your network name in the list. If it is not there, your router is not broadcasting. If it is there but says "connected with no internet," your router is on but not talking to the modem.
- If you are not connected to WiFi at all, look at your router. Most routers have a WiFi light on the front. If it is off or red, the router is not broadcasting. If it is on, try moving closer to the router and connecting again.
- If you are connected to WiFi but pages will not load, try opening a different website. If some sites load and others do not, the problem is not your connection — it is those specific websites.
This process narrows down whether the problem is your modem, your router, your provider's network, or the website you are trying to reach.
When one website works but another does not
If you can load Google.com but not Facebook.com, or if you can watch YouTube but not Netflix, the problem is not your internet connection. Your modem and router are working fine. The issue is on that website's end — their servers might be overloaded, they might be doing maintenance, or there might be a problem with their network.
You can check whether a website is down by opening a new browser tab and searching "[website name] down" or by visiting a site like DownDetector.com, which shows real-time reports of outages. If thousands of people are reporting the same website down, you know it is not your problem and you just have to wait.
If only one website is down and you need to know whether it is temporary, check back in 15 minutes. Most website outages last less than an hour.
Restarting your modem and router the right way
Restarting fixes most internet problems because it clears out stuck connections and forces your equipment to reconnect to your provider. The order matters: you restart the modem first, then the router.
- Unplug the power cable from the back of your modem. Wait 30 seconds. Plug it back in.
- Wait for the lights on the modem to stabilize. You should see a solid green or blue internet light. This usually takes 2 to 3 minutes.
- Once the modem is stable, unplug the power cable from your router. Wait 30 seconds. Plug it back in.
- Wait for the WiFi light on your router to turn solid. This usually takes another 2 to 3 minutes.
- Try loading a website again.
If restarting does not work, leave both devices unplugged for a full minute instead of 30 seconds, then plug the modem in first and wait for it to fully stabilize before plugging in the router.
Checking whether your provider has an outage
Before you spend 20 minutes restarting equipment, check whether your internet provider is having an outage in your area. Most providers have a status page you can reach from your phone using cellular data.
Search "[your provider name] status page" — for example, "Comcast status page" or "Verizon status page." The status page will show you whether there is a known outage in your zip code. If there is, you know the problem is not your equipment and you just have to wait for the provider to fix it.
If there is no outage listed but you still cannot connect, then you know the problem is your modem, your router, or your account. This is when restarting makes sense.
When to contact your internet provider
Contact your provider if restarting both devices does not fix the problem and there is no outage listed on their status page. Before you call, have this information ready: your account number (on your bill), the lights you see on your modem, and what happens when you try to connect (does the WiFi network appear, or is there nothing to connect to).
Most providers can run a test from their end to see whether your modem is talking to them. If the modem is not communicating with the provider's network, the provider might send a technician or mail you a replacement modem. If the modem is communicating fine, the problem is usually your router, and you may need to replace it.
If you rent your modem from the provider, they will replace it for free. If you own your router, you will need to buy a new one if it fails.
Frequently Asked Questions
Why do I need to restart the modem before the router?
The modem connects to your provider's network, and the router connects to the modem. If you restart the router first, it will try to reconnect to a modem that is still booting up, and they might not sync properly. Restarting the modem first ensures it is fully connected to your provider before the router tries to use it.
What does it mean if my modem has a red light?
A red light usually means the modem is not connected to your provider's network. This can happen if the cable line is loose, if there is an outage, or if the modem itself is failing. Check that the cable going into the modem is plugged in firmly, then restart the modem. If the light stays red after restarting, contact your provider.
Can I use the internet if I am connected to WiFi but it says "no internet"?
No. That message means your router is on and broadcasting, but it cannot reach the modem or the modem cannot reach your provider. Restart the modem first, wait for it to stabilize, then restart the router. If the message persists, the problem is likely between your modem and your provider's network.
Why does my internet work on my phone but not my computer?
Your phone might be using cellular data instead of WiFi. Check your phone's WiFi settings to see which network you are connected to. If your phone is on WiFi and your computer is not, try connecting your computer to the same WiFi network. If your computer will not connect to WiFi, the problem is your computer's WiFi adapter, not your internet connection.
Is it bad to restart my modem and router often?
No. Restarting is safe and does not damage the equipment. Most people restart their modem and router once every few months. If you find yourself restarting more than once a week, contact your provider — that usually means something is failing or your connection is unstable.
