Start with the simplest fixes first
Most internet connection problems come from something turned off, unplugged, or set to the wrong mode — not from broken hardware or your internet service itself. Before you call your provider or take your computer in for repair, spend five minutes checking the physical things: whether your modem and router are plugged in and powered on, whether airplane mode is accidentally turned on, and whether your Wi-Fi is actually broadcasting.
The fastest way to know if the problem is your computer or your internet is to test another device. If your phone connects to Wi-Fi but your laptop does not, the problem is your laptop. If nothing connects, the problem is your modem, router, or internet service.
Key Takeaways
- Restart your modem and router by unplugging them for 30 seconds, then plugging them back in — this fixes most connection problems.
- Check whether airplane mode is on in your computer's settings, and whether your Wi-Fi network appears in your available networks list.
- If your modem has no lights on or shows a red light, your internet service may be down in your area or your modem may need a restart.
- If one device cannot connect but others can, the problem is that device's Wi-Fi settings or driver, not your internet.
- Your internet provider's support line can tell you in seconds whether service is down in your area.
Check your modem and router lights
Your modem and router each have lights on the front that tell you their status. A modem should show a solid green or white light for internet connection — if it shows red, orange, or is completely dark, your internet service is either down or your modem is not powered on. A router should show a solid or blinking light for Wi-Fi — if there is no light at all, it is not powered on.
Unplug both your modem and router from the wall outlet, wait 30 seconds, then plug them back in. This is called a power cycle and fixes the majority of connection problems. Wait two to three minutes for them to fully restart — you will see the lights change and stabilize. Try connecting again.
If your modem still shows no light or a red light after restarting, your internet service may be down. Call your internet provider's support line and tell them what color light you see. They can check whether service is down in your area and whether your account is active.
Turn off airplane mode and check Wi-Fi settings
Airplane mode disables all wireless connections on your computer. On Windows, look in the bottom right corner of your screen for a Wi-Fi icon — if it has a line through it or shows "airplane mode on," click it and turn airplane mode off. On Mac, click the Wi-Fi icon in the top right corner and make sure "Wi-Fi" is checked, not grayed out.
After airplane mode is off, look at your available Wi-Fi networks. On Windows, click the Wi-Fi icon and look for your network name — it should appear in the list. On Mac, click the Wi-Fi icon and your network should be listed. If you do not see your network name, your router may not be broadcasting or may be too far away. Move closer to the router and wait 10 seconds, then check again.
If you see your network, click it and enter your Wi-Fi password. The password is usually on a sticker on the back or bottom of your router. If you enter the password and it says "incorrect password," try again slowly — passwords are case-sensitive, meaning capital letters matter.
Forget the network and reconnect
Sometimes your computer remembers incorrect settings for your Wi-Fi network and will not reconnect even with the right password. Forgetting the network and reconnecting from scratch often fixes this.
On Windows, go to Settings, then Network and Internet, then Wi-Fi, then Manage Known Networks. Find your network name, click it, and click Forget. Then go back to your available networks, click your network name again, and enter the password.
On Mac, go to System Settings, then Wi-Fi, then click Details next to your network name. Click Forget Network, then go back and select your network again and enter the password.
Check your internet provider's service status
Before spending time troubleshooting your computer, find out whether your internet service itself is down. Most internet providers have a service status page on their website or a phone number you can call. Search "[your provider name] service status" or look at your bill to find the support number.
When you call, tell them your address and account number. They can tell you in under a minute whether service is down in your area, whether your account is active, and whether your modem is registered on their network. If service is down, there is nothing to fix on your end — you wait for them to restore it.
Update or reinstall your Wi-Fi driver
Your computer's Wi-Fi driver is software that lets your computer talk to your Wi-Fi card. If the driver is outdated or corrupted, your computer may not see any networks or may disconnect constantly.
On Windows, right-click the Start button, click Device Manager, and look for Network Adapters. Click the arrow next to it to expand the list. Find the one with "Wireless" or "Wi-Fi" in the name, right-click it, and click Update Driver. Choose "Search automatically for updated driver software" and let Windows search. If an update is found, install it and restart your computer.
If updating does not work, right-click the same device and click Uninstall Device. Restart your computer — Windows will automatically reinstall the driver. This often fixes connection problems that updates alone do not solve.
On Mac, driver updates happen automatically through System Updates. Go to System Settings, click General, then Software Update, and install any updates available. Restart your computer when prompted.
Check your router placement and interference
Wi-Fi signals weaken when they travel through walls, metal, or water. If your router is in a closet, behind a filing cabinet, or in a basement corner, move it to a central, open location in your home. Place it on a shelf or table rather than on the floor, and keep it away from microwaves, cordless phones, and baby monitors — these devices broadcast on the same frequency and can interfere with Wi-Fi.
If you are far from the router, move closer and test the connection. If it works better nearby, your router may not have enough range for your space. You may need a Wi-Fi extender or a new router with better range, but first confirm that distance is actually the problem.
Frequently Asked Questions
What does it mean when my modem light is blinking instead of solid?
A blinking light usually means your modem is working but is still connecting or is sending data. Wait a few minutes — if it stays blinking and you still cannot connect, restart the modem by unplugging it for 30 seconds. If it never becomes solid, call your internet provider.
My computer says "no internet, secured" even though I am connected to Wi-Fi. What does that mean?
Your computer is connected to the Wi-Fi network but cannot reach the internet. Restart your modem and router. If that does not work, restart your computer. If the problem continues, call your internet provider to check whether service is down or whether your modem is registered correctly on their network.
Why does my internet work on my phone but not my laptop?
The problem is your laptop, not your internet. Try forgetting the network on your laptop and reconnecting with the password. If that does not work, update your Wi-Fi driver. If you still cannot connect, your laptop's Wi-Fi card may be damaged and need replacement.
Can I fix this without restarting my modem?
Most connection problems require a modem restart to fix. Restarting takes three minutes and solves the majority of issues without any other work. It is always the first step to try.
My internet keeps dropping and reconnecting. What causes that?
Constant disconnections usually mean your modem is overheating, your router is too far away, or your Wi-Fi driver is outdated. Restart your modem, move closer to the router, and update your Wi-Fi driver. If disconnections continue, call your internet provider — the problem may be on their end.
