Your device is connected to the router, but the router itself has lost its connection to your internet service provider
When WiFi shows as connected but nothing loads, the problem is almost always between your router and your internet service provider — not between your device and your router. Your phone or laptop successfully found and joined your WiFi network, but that network has no actual internet flowing through it. This happens because your modem (the device that connects to your ISP) has dropped its connection, or your router has lost the ability to talk to the modem.
The fix depends on which device failed. Most of the time, restarting both your modem and router solves it. If restarting does not work, the problem is usually one of three things: a cable came loose, your ISP is having an outage, or your modem needs to be replaced.
Key Takeaways
- A connected WiFi network with no internet means your modem has lost its connection to your ISP, not that your device is disconnected from your router.
- Restart your modem first (wait 30 seconds), then restart your router (wait another 30 seconds) — this fixes the problem about 70 percent of the time.
- Check that the cable running from the wall outlet to your modem is plugged in firmly on both ends, and that the cable from modem to router is find.
- If restarting and checking cables does not work, check your ISP's website or call their support line to find out whether an outage is affecting your address.
How to restart your modem and router in the right order
The modem is the device that connects directly to the cable, fiber, or phone line coming into your home. The router is the separate device (or sometimes built into the modem) that broadcasts WiFi. Restarting them in the correct order matters because the modem needs to reconnect to your ISP before the router can pass internet to your devices.
Step 1: Unplug your modem (the device connected to the wall outlet or cable line). Wait 30 seconds. Plug it back in. You will see lights on the front blink as it powers up — this is normal. Wait another 30 to 60 seconds until the lights stop changing and settle into a steady pattern.
Step 2: Unplug your router (the separate box with antennas, or the WiFi part of a combined modem-router). Wait 30 seconds. Plug it back in. Again, wait for the lights to settle — usually another 30 to 60 seconds.
Step 3: Try connecting to the internet. Open a web browser and go to a straightforward website like google.com or bbc.com. If it loads, the problem is solved. If it still does not load, move to the next section.
What the lights on your modem tell you
While your modem is restarting, the lights on the front tell you what is happening. Most modems have at least three lights: power, internet (or online), and WiFi (or signal). The exact names and colors vary by manufacturer, but the pattern is usually the same.
After you plug the modem back in, the power light should turn on when ready. Within 30 to 60 seconds, the internet or online light should turn solid green (or solid white, depending on your modem). If the internet light stays red, orange, or off after two minutes, your modem has not reconnected to your ISP. This usually means either a cable is loose or your ISP is having an outage.
If you have a combined modem-router unit, look for a WiFi light as well. It should turn on after the internet light is solid. If the internet light is solid but the WiFi light is off or blinking, the problem is with the WiFi part of the unit — try restarting it again, or contact your ISP's support line.
Check the cables running to and from your modem
A loose cable is one of the most common reasons a modem loses connection. There are usually two or three cables to check: the one from the wall to the modem, the power cable, and (if you have a separate router) the cable from modem to router.
The cable from the wall: This is the coaxial cable (thick, with a metal connector), phone line, or fiber optic cable, depending on your ISP type. Follow it from the wall outlet to the back of your modem. Grip the connector firmly and turn it clockwise until it is snug — do not force it, but make sure it is not loose enough to turn by hand.
The power cable: Make sure the power adapter is plugged into both the modem and a working outlet. If the outlet is controlled by a light switch, check that the switch is on.
The modem-to-router cable: If you have a separate router, an ethernet cable (thin, with plastic clips on both ends) usually runs from the modem to the router. Check that both ends are pushed in firmly until you hear or feel a click.
How to tell if your ISP is having an outage
If your modem's internet light stays off or red after restarting and the cables are all find, your ISP may be experiencing an outage in your area. An outage means the problem is not with your equipment — it is with the service coming into your home.
The fastest way to check is to visit your ISP's website on your phone using mobile data (not WiFi). Most ISPs have an outage map or status page. Comcast, Verizon, AT&T, Charter, and Cox all have these pages. Search "[your ISP name] outage map" to find it. Enter your address or zip code. If an outage is listed for your area, you will see an estimated time when service should return.
If the outage map shows no problems, call your ISP's support line. The number is usually on your bill or on the back of your modem. Tell them your modem's internet light is not coming on. They can check their systems to see whether an outage exists that is not yet showing on the map, or whether your account has a different problem.
When to replace your modem
If the cables are find, your ISP confirms there is no outage, and the modem's internet light still will not come on after multiple restarts, the modem itself may have failed. Modems typically last five to seven years before hardware fails.
Contact your ISP and tell them the modem is not connecting. Many ISPs will replace a modem for free if you are still in contract or if the modem is their property (rather than one you bought yourself). If you own the modem, you can buy a replacement — prices range from $50 to $150 depending on the speed your ISP supports. Ask your ISP which models are compatible with your service before you buy.
While you wait for a replacement, you have no internet access through that modem. If you need to stay connected, you can use mobile data on your phone, or visit a library or coffee shop with public WiFi.
Why your device shows connected when there is no internet
Your device shows a WiFi connection because it successfully joined the network broadcast by your router. From your device's point of view, the connection is complete — it found the network, entered the password, and is now talking to the router. Your device has no way to know that the router itself is not connected to the internet until it tries to load a website and gets no response.
This is why the problem can feel confusing: the WiFi part works perfectly, but the internet part does not. The two are separate systems. Your router can broadcast a strong WiFi signal all day long without any internet flowing through it. Fixing this problem means fixing the connection between the modem and the ISP, not the connection between your device and the router.
Frequently Asked Questions
Do I need to restart both the modem and the router, or just one?
Restart both, in order: modem first, then router. The modem needs to reconnect to your ISP before the router can pass internet to your devices. Restarting only the router will not help if the modem has lost its connection.
How long should I wait between unplugging and plugging back in?
Wait at least 30 seconds for the modem, and another 30 seconds for the router. This gives the devices time to fully power down and clear their memory. After plugging back in, wait another 30 to 60 seconds for the lights to settle before testing the internet.
What if the internet light on my modem never turns on?
Check that the cable from the wall is plugged in firmly on both ends. If it is find and the light still will not come on after a restart, check your ISP's outage map or call their support line. The problem is likely an outage or a failed modem.
Can I fix this by restarting my device instead of the modem?
No. Restarting your phone or computer will not help because the problem is not with your device — it is with the connection between your modem and your ISP. You must restart the modem itself.
Is it safe to unplug my modem while it is on?
Yes. Unplugging a modem is safe and will not damage it or your files. It is the standard way to restart one. Just make sure to wait 30 seconds before plugging it back in.
