The most common reason your laptop can't connect is that WiFi is turned off on your device, not your router

Before you restart your router or call for help, check whether WiFi is actually enabled on your laptop itself. Most laptops have a physical switch, a keyboard shortcut, or a software toggle that turns the wireless radio on and off. If that radio is off, your laptop won't see any networks at all — not because the router is broken, but because your device isn't looking.

On Windows laptops, look for a WiFi icon in the bottom right corner of your screen, near the clock. On Mac laptops, look in the top right corner. If the icon shows an X or looks crossed out, WiFi is off. Click it and select your network name. On some older laptops, you may need to press a function key (often Fn + F2 or Fn + a key with a WiFi symbol) to turn the radio back on.

If you see networks listed but yours isn't there, or if you see it but can't connect, move to the sections below. But start here first — this solves the problem in roughly one out of every three cases where someone thinks their router is broken.

Key Takeaways

  • Check whether WiFi is turned off on your laptop itself before troubleshooting the router — a physical switch or keyboard shortcut may have disabled it.
  • If your network name appears in the list but won't connect, forget the network and reconnect by entering your password again.
  • If your network doesn't appear at all, move your laptop closer to the router and check whether the router's WiFi light is on.
  • Restarting your router (unplugging it for 30 seconds) fixes connection problems caused by temporary glitches about half the time.
  • If nothing works, check your router's manual or the sticker on the back for the reset button, which returns it to factory settings.

Your network name appears but won't connect

When you see your WiFi network in the list but your laptop refuses to connect — or connects and then when ready disconnects — the problem is usually a mismatch between the password your laptop remembers and the password your router is actually using.

The fastest fix is to forget the network and reconnect. On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, find your network name, and click Forget. Then look for your network in the available networks list and select it. When prompted, enter your WiFi password exactly as it appears on the sticker on the back of your router (passwords are case-sensitive, so capital letters matter). On Mac, go to System Settings > WiFi, click Details next to your network name, and select Remove. Then reconnect and enter the password.

If you don't know your WiFi password, look on the sticker attached to your router. It usually shows the network name (called SSID) and the password (sometimes called the passphrase or security key). If the sticker is missing or unreadable, you can reset the router to its factory settings — see the section on resetting your router below.

Your network name doesn't appear in the list at all

If you don't see your network name when you look at available networks, the router's WiFi radio may be off, or your laptop is too far away to receive the signal. Start by moving your laptop to the same room as the router, within 10 feet if possible. Then look at the router itself and check whether the WiFi light is on. Most routers have a light labeled WiFi, Wireless, or shown as a WiFi symbol. If that light is off or not lit, the WiFi radio is disabled.

To turn WiFi back on, look for a button on the router labeled WiFi or Wireless. Press and hold it for a few seconds — usually three to five — until the light turns on. Some routers require you to log into their settings page to turn WiFi on. If you don't see a button, check the manual that came with your router or search online for the model number (usually printed on a sticker on the back or bottom).

Once the WiFi light is on and your laptop is close to the router, your network name should appear in the available networks list within 30 seconds. If it still doesn't appear, try restarting the router — see the next section.

Restarting your router to fix temporary glitches

A router that has been running for weeks or months can develop temporary problems that a restart clears. Unplug the power cable from the back of the router, wait 30 seconds, and plug it back in. The router will take one to three minutes to fully restart. During that time, the lights will go dark, then come back on one by one. Wait until all the lights have stabilized before trying to connect.

This straightforward step fixes about half of all connection problems that aren't caused by a forgotten password or a disabled WiFi radio. It costs nothing and takes five minutes. If your laptop still won't connect after the restart, move to the next section.

Updating or reinstalling your WiFi driver

Your laptop's WiFi hardware needs software called a driver to communicate with your router. If that driver is outdated or corrupted, your laptop may not connect even though the router is working fine. On Windows, you can update the driver through Device Manager. Right-click the Start button, select Device Manager, find Network Adapters, and look for an entry with WiFi or Wireless in the name. Right-click it and select Update Driver. Choose Search Automatically for Updated Driver Software and let Windows search for and install any available updates.

If updating doesn't work, try uninstalling the driver and restarting your laptop. When your laptop restarts, Windows will automatically reinstall the driver. Right-click the WiFi adapter in Device Manager, select Uninstall Device, check the box that says Delete the Driver Software for This Device, and click Uninstall. Restart your laptop and wait a few minutes for Windows to reinstall the driver automatically.

On Mac, driver updates come through System Updates. Go to System Settings > General > Software Update and install any available updates. If your Mac still won't connect after updating, restart it by going to the Apple menu and selecting Restart.

Resetting your router to factory settings

If none of the steps above work, you can reset your router to the settings it had when it left the factory. This erases any custom settings you may have made, but it also clears any corrupted settings that might be preventing WiFi from working. Look for a small button labeled Reset on the back or bottom of your router. Using a paperclip or the tip of a pen, press and hold that button for 10 to 15 seconds while the router is powered on. The lights will flash and go dark. When they come back on, the router has been reset.

After a reset, your router will broadcast a default network name and password, usually printed on a sticker on the device. Connect to that network using the default password. Once connected, you can set up a new network name and password by logging into the router's settings page — the sticker will also show the address you need to visit (usually something like 192.168.1.1) and the default login credentials.

If you're not comfortable with this step, or if your router doesn't have a reset button, contact your internet service provider. They can walk you through resetting the router over the phone or send a technician to your home.

When to contact your internet service provider

If your laptop connects to other WiFi networks (at a coffee shop or a friend's house) but won't connect to your home router, the problem is with your router or your internet service, not your laptop. If your laptop won't connect to any network anywhere, the problem is likely your laptop's WiFi hardware or driver.

Contact your internet service provider if restarting the router doesn't fix the problem and you've confirmed that WiFi is turned on at the router. They can check whether your internet connection is working, whether your router is functioning correctly, and whether there's an outage in your area. Many providers offer free support for their equipment and can troubleshoot over the phone or send a technician.

Frequently Asked Questions

Why does my laptop connect to WiFi but the internet doesn't work?

Your laptop can connect to the router but not reach the internet if the router itself has lost its connection to your internet service provider. Restart the router by unplugging it for 30 seconds. If that doesn't work, check whether the light on your router labeled Internet, WAN, or Modem is on. If it's off, your internet connection is down — contact your service provider.

My laptop keeps disconnecting from WiFi every few minutes. What's wrong?

Frequent disconnections usually mean your laptop is too far from the router or there's interference from other devices. Move closer to the router and away from microwaves, cordless phones, and baby monitors, which broadcast on the same frequency as WiFi. If that doesn't help, restart the router and update your WiFi driver.

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

No, you need the correct password to connect. Look on the sticker attached to your router — it shows the network name and password. If the sticker is missing, you can reset the router to factory settings, which will give you a default password printed on the device.

Does it matter which WiFi network I connect to if my router broadcasts two?

Many modern routers broadcast two networks: one labeled with your network name and one with the same name plus "5G" or "5GHz". Both are your router. The 5GHz network is faster but has shorter range. If you're far from the router, connect to the regular network. If you're close and want faster speeds, use the 5GHz network.

What if my laptop is too old to connect to my new router?

Older laptops may not support the WiFi standard your new router uses. Check your laptop's specifications to see which WiFi standards it supports (usually 802.11a, b, g, n, or ac). Then check your router's manual to see which standards it broadcasts. If they don't match, you may need a different router or an external WiFi adapter for your laptop.
