The most common reasons your device can't connect

Your device can't connect to WiFi for one of a few specific reasons: the router isn't broadcasting the network name, your device has the wrong password, the router has stopped responding, your device's WiFi hardware isn't working, or the router is too far away or blocked by walls. Most of the time it's the password or the router needs to be restarted. Start by checking those two things before moving to the others.

The error message you see matters. "Can't connect to this network" usually means the password is wrong or the router isn't broadcasting. "Connected but no internet" means your device found the router but the router itself has no connection to your internet service provider. "Can't find the network" means your device isn't seeing the router at all.

Key Takeaways

  • Restart your router by unplugging it for 30 seconds, then plugging it back in — this fixes most connection problems.
  • Check that you are typing the WiFi password correctly, including capital letters and special characters exactly as they appear on your router's label.
  • Move closer to the router and away from thick walls, metal objects, and other electronics that can block the signal.
  • If your device still won't connect after restarting the router and checking the password, restart your device itself.
  • If only one device can't connect while others can, the problem is with that device's WiFi hardware, not your router.

Restart your router first

Restarting the router fixes the majority of WiFi problems. Unplug the power cable from the back of the router, wait 30 seconds, then plug it back in. The lights on the front will go dark, then come back on one by one. Wait until they stop changing — usually two to three minutes — before trying to connect again.

A restart clears the router's memory, closes stuck connections, and forces it to re-establish contact with your internet service provider. It costs nothing and takes five minutes. If your internet comes back after a restart, you are done. If it doesn't, move to the next step.

Check your WiFi password

The password is case-sensitive, meaning capital letters are different from lowercase letters. Look at the label on the bottom or back of your router — it usually shows the network name (called the SSID) and the password printed together. Type the password exactly as it appears, including capitals, numbers, and special characters like hyphens or underscores.

If you don't have the label, you can reset the password through your router's settings page. Open a web browser on a device that is connected to the router, type 192.168.1.1 or 192.168.0.1 into the address bar, and log in with the username and password printed on the router (often "admin" and "admin" or "admin" and the router's serial number). From there you can change the WiFi password to something you will remember. Write it down and keep it somewhere safe.

Move closer to the router and remove obstacles

WiFi signal weakens with distance and gets blocked by walls, especially thick concrete or plaster walls, metal objects, and other electronics. If your device is far from the router or separated by multiple walls, move it closer and try again. Even moving from one room to the next can make a difference.

Keep the router away from microwaves, cordless phones, baby monitors, and metal filing cabinets — these devices broadcast on the same frequency and can interfere. If your router is in a closet or cabinet, move it to an open shelf or the center of a room. Routers work best when they are elevated and in the open.

Restart your device

If the router is working and other devices can connect, but one specific device cannot, restart that device. Power it off completely, wait 10 seconds, then power it back on. This clears the device's WiFi memory and forces it to reconnect from scratch.

After the device restarts, go back to your WiFi settings, find your network name, and connect again using the correct password. If it still won't connect, try "forgetting" the network first: go to your WiFi settings, find the network name, and select "Forget" or "Remove". Then reconnect by selecting the network again and entering the password.

Check if your device's WiFi hardware is working

If your device still won't connect after restarting both the router and the device, the problem may be with your device's WiFi hardware. Check whether WiFi is turned on — many laptops and phones have a physical switch or keyboard shortcut to disable WiFi. Look for an airplane mode setting and make sure it is off.

If WiFi is on but your device won't connect to any network, not just yours, the WiFi card or antenna inside your device may be damaged. This is a hardware problem that usually requires a repair shop. If your device is old or has been dropped, this is more likely. If your device is new and this is the first time you are trying to connect, contact the device manufacturer's support line.

Verify your internet service is actually working

If your device says "connected but no internet" or if multiple devices can connect to the router but none of them have internet, the problem is not your WiFi — it is your connection to your internet service provider. Check whether the lights on your router are the normal color. Most routers have a light that shows internet status — if it is red, orange, or off, your service is down.

Restart the modem (the device that connects your router to your internet service provider). It is usually a separate box with cables running to it. Unplug it for 30 seconds, plug it back in, and wait for the lights to stabilize. If the internet light is still not green or blue, contact your internet service provider — they can tell you whether there is an outage in your area or whether your account has an issue.

Frequently Asked Questions

Why does my password keep saying it's wrong when I know it's correct?

Passwords are case-sensitive, so "MyPassword" is different from "mypassword". Check the label on your router and match the capitals exactly. If you still can't get it right, reset the password through the router's settings page at 192.168.1.1 or 192.168.0.1, then use the new password you create.

My device connects but then disconnects after a few seconds. What's wrong?

This usually means the signal is weak or unstable. Move closer to the router and away from walls and metal objects. If that doesn't work, restart the router and your device. If disconnections keep happening, your device may be too far away or the router may need a firmware update — check the router manufacturer's website for updates.

Can I connect to WiFi if I don't know the password?

No, you need the correct password to connect. If you don't have it, you can reset the router to factory settings by holding the reset button for 10 seconds, but this will erase all your settings. It is easier to log into the router at 192.168.1.1 and change the password there if you know the admin login.

Why can some devices connect but others can't?

If your phone connects but your laptop doesn't, the problem is with the laptop's WiFi hardware or settings, not your router. Try restarting the laptop, forgetting the network, and reconnecting. If multiple devices of the same type won't connect, check whether they are all using the same password or whether one of them has an older WiFi standard your router doesn't support.

How far away can I be from my router and still connect?

Most home routers work reliably within 100 to 150 feet in open space, but walls and obstacles cut that range in half. If you need WiFi further away, move the router to a more central location or add a WiFi extender or mesh system to expand coverage.
