Start with the simplest fixes first
Wireless internet fails for a handful of reasons, and most of them are fixable in under five minutes. Before you call your internet provider or buy new equipment, check four things in this order: whether your router is powered on, whether you are in range of the signal, whether the network name appears in your device's list, and whether you entered the password correctly.
If your router has lights on the front, look for one labeled "power" or "internet" — it should be solid or blinking, not off. If it is off, plug the power cable in firmly or try a different outlet. If the lights are on but you see no wireless networks when you search, restart the router by unplugging it for 30 seconds, then plugging it back in. This clears temporary errors that prevent the radio from broadcasting.
Walk closer to the router. Wireless signals weaken with distance and through walls. If the network appears when you are near the router but not in another room, the signal is too weak to reach that far — this is a coverage problem, not a broken connection.
Key Takeaways
- Restart your router by unplugging it for 30 seconds before trying anything else, because most wireless failures clear on their own.
- Check that your device is connecting to the correct network name and that you entered the password without typos.
- Wireless signals weaken through walls and distance, so moving closer to the router tests whether the problem is range or a real fault.
- If your router shows no internet light or your modem is unplugged, your internet service itself is down — contact your provider.
- Interference from microwaves, cordless phones, and neighboring networks can slow or drop your connection even when the signal appears strong.
Verify your device is actually connected to your network
Many people think they are connected when they are not. On your phone or computer, open the list of available wireless networks. Look for your network name — this is the SSID, usually printed on a sticker on your router. If you see it, tap or click it and enter your password. If the password is wrong, the device will say "incorrect password" or "cannot connect to this network."
If you do not see your network name in the list at all, the router is not broadcasting. Restart the router. If the name still does not appear after two minutes, the wireless radio inside the router may be off — some routers have a physical button or switch labeled "WiFi" or "wireless" that you can toggle. Check the back or sides of the device.
Once your device shows it is connected, open a web browser and try to load a website. If the page does not load, you are connected to the network but the network has no internet. This means the problem is between your router and your internet provider, not between your device and the router.
Check whether your internet service is actually working
Your router needs two things to give you wireless internet: power and an active internet connection from your provider. If the router is on but you have no internet, look at the modem — the separate box that connects to your wall outlet or cable line. The modem should have a light labeled "internet," "online," or "WAN." If that light is off or red, your service is down.
Restart the modem by unplugging it for 30 seconds, then plugging it back in. Wait two minutes for it to fully restart — the lights will blink and then settle. If the internet light comes back on, your service is restored. If it stays off, your internet provider has an outage or your account has an issue.
Check your provider's website or call their support line to see if there is an outage in your area. If there is no outage, the problem is usually a loose cable, an unpaid bill, or a modem that needs replacement. Your provider can tell you which one over the phone.
Move the router to a better location
Wireless signals travel poorly through metal, water, and thick walls. If your router is in a closet, inside a cabinet, or on the floor behind a couch, move it to an open, elevated spot — a shelf or table in a central room works best. Signals bounce off hard surfaces, so a router in the middle of your home reaches more rooms than one in a corner.
Keep the router away from microwaves, cordless phones, baby monitors, and Bluetooth speakers. These devices use the same radio frequencies as WiFi and can jam the signal when they are close by. If your internet slows down when someone uses the microwave, this is the problem — move the router at least six feet away.
If you live in an apartment or dense neighborhood, your router may be competing with dozens of other networks on the same channel. This is called interference. You can change your router's channel through its settings page — usually accessed by typing 192.168.1.1 or 192.168.0.1 into a web browser. Look for a setting called "channel" or "WiFi channel" and try switching from channel 1, 6, or 11 (the non-overlapping channels on the 2.4 GHz band). If you have a newer router with 5 GHz, that band has more channels and usually less interference.
Restart your device and forget the network
Sometimes your phone or computer holds onto old connection settings that prevent it from connecting properly. Restart your device completely — turn it off and back on. Then, in your network settings, find your wireless network and select "forget this network" or "remove." Search for the network again and reconnect by entering your password fresh.
On Windows, open Settings, go to Network & Internet, then WiFi, and select "Manage known networks." Find your network and click "Forget." On Mac, open System Settings, go to WiFi, click the details icon next to your network, and select "Forget." On iPhone, go to Settings, WiFi, tap the info icon next to your network, and select "Forget This Network." On Android, long-press your network name in the WiFi list and select "Forget."
After forgetting the network, search for it again and reconnect. This forces your device to re-authenticate with the router and often clears connection problems that restart alone does not fix.
Check for router or modem problems that need replacement
If you have restarted both the router and modem, verified your device is connected, and confirmed your internet service is active, but you still have no internet, the router or modem hardware may be faulty. Look at the lights on both devices. A modem should show lights for power, internet, and read activity. A router should show lights for power, internet, and wireless activity.
If the lights are off or stuck in one state (not blinking), the device may have crashed. Try unplugging it for a full minute, then plugging it back in and waiting three minutes for it to fully boot. If the lights still do not respond normally, the device is likely broken and needs replacement.
Contact your internet provider. If the modem is theirs (rented, not purchased), they will replace it for free. If you own the modem, you will need to buy a new one — ask your provider which models work with your service. If the router is the problem, you own it and will need to replace it yourself, or you can rent a combined modem-router unit from your provider.
Understand when to contact your internet provider
Call your provider if the modem's internet light is off after a restart, if you see no internet outage but your service is still down, or if you have done all the steps above and still have no connection. Have the following information ready: your account number (on your bill), the model number of your modem (on the device itself), and a description of what you have already tried.
Your provider can run a line test from their office to see if the problem is on their side or yours. They can also push a restart signal to your modem remotely, which sometimes works when a manual restart does not. If the line test shows your service is working but your modem is not responding, they will send a replacement or a technician.
If you are told a technician needs to visit, ask how long the appointment window is and whether there is a fee. Some providers charge for in-home visits if the problem is determined to be your equipment, not theirs.
Frequently Asked Questions
Why does my wireless internet work in one room but not another?
Wireless signals weaken with distance and through walls. If you are more than 50 feet from the router or separated by multiple thick walls, the signal may be too weak to connect. Move the router to a more central location or buy a WiFi extender to boost the signal in distant rooms.
My internet is slow but not completely down. What causes that?
Slow wireless is usually caused by interference from other networks or devices, too many devices connected at once, or your device being far from the router. Try moving closer, restarting the router, or switching to a less crowded WiFi channel. If only one device is slow, restart that device.
How do I know if the problem is my router or my internet service?
Plug a computer directly into the modem with an ethernet cable. If the internet works on the wired connection, your service is fine and the router is the problem. If the wired connection also does not work, your service is down and you need to contact your provider.
Can I fix my wireless by changing the password?
Changing the password will not fix a connection that is already broken, but it can help if you suspect someone else is using your network and slowing it down. Change the password through your router's settings page, then reconnect your devices with the new password.
What should I do if my router keeps disconnecting me?
Restart the router first. If disconnections continue, move the router away from interference sources like microwaves. If the problem persists, the router may be overheating — make sure it has space around it and is not in direct sunlight. If none of that helps, the router hardware may be failing and needs replacement.
