Start with the simplest fixes first
Most WiFi problems disappear after restarting your router and the device that won't connect. Power off your router completely — unplug it from the wall — and wait 30 seconds. While it restarts, restart the device you're trying to use: phone, laptop, or tablet. Turn it off, wait 10 seconds, and turn it back on. This clears temporary errors in both machines and often restores a working connection within two minutes.
If that does not work, move your device closer to the router. WiFi signal weakens with distance and through walls. If the connection works well in the same room as the router but fails in another part of your home, the problem is likely signal strength, not a broken connection. This tells you whether to try repositioning the router or whether something else is wrong.
Key Takeaways
- Restart your router by unplugging it for 30 seconds, then restart the device that won't connect — this fixes most temporary connection problems.
- Move closer to the router to test whether weak signal is the problem; if the connection works nearby but not in other rooms, reposition the router to a central location.
- Check that you are connecting to the correct network name and that you have entered the password correctly, including capital letters and numbers.
- If your device connects but the internet does not work, restart your modem (the device your internet provider gave you) separately from the router.
- If nothing works after these steps, contact your internet provider to check whether service is down in your area or whether your account has an issue.
Verify you are using the correct network and password
Your router broadcasts a network name, called the SSID, that appears in the list of available networks on your device. Check that you are connecting to the right one — if you live in an apartment or near neighbors, you may see several network names. The one you want is the name you set up when you first installed your router, or the default name printed on a sticker on the router itself.
Passwords are case-sensitive, meaning capital letters and lowercase letters are different. If you typed the password and it did not work, check whether Caps Lock is on. Numbers and special characters (like hyphens or exclamation marks) must also be exact. If you cannot remember the password, look for it on the sticker on your router, or log into your router's settings page to view or reset it. Your router's instruction manual or the manufacturer's website will show you how to access those settings.
Check whether your device is forgetting the network
Some devices disconnect and "forget" a WiFi network after a period of time, especially if the signal is weak. On most phones and laptops, you can tell the device to "forget" the network and then reconnect to it fresh. This clears out any corrupted connection information.
On an iPhone or iPad, go to Settings, then WiFi, find your network name, tap the information icon next to it, and select "Forget This Network." Then reconnect by selecting the network again and entering the password. On an Android phone, go to Settings, then WiFi, long-press your network name, and select "Forget." On a Windows laptop, go to Settings, then Network, then WiFi, select "Manage Known Networks," find your network, and click "Forget." On a Mac, hold Option and click the WiFi icon in the menu bar, then select "Manage Networks," highlight your network, and click the minus button.
Separate your modem from your router problem
Your internet provider gave you a modem — the device that connects to the wall outlet and brings internet into your home. Your router is the separate device (or sometimes built into the modem) that broadcasts WiFi. If your device connects to WiFi but cannot reach the internet, the problem is usually the modem, not the router.
Restart your modem by unplugging it from the wall and waiting 30 seconds, just as you did with the router. If you have both a separate modem and router, unplug the modem first, wait 30 seconds, plug it back in, and wait for all its lights to stop blinking (usually two to three minutes). Then unplug and restart the router. This order matters because the router depends on the modem to reach the internet.
If restarting the modem does not fix the problem, the issue may be with your internet service itself. Contact your internet provider to ask whether service is down in your area or whether there is a problem with your account.
Reposition your router for better signal throughout your home
WiFi signal travels best in straight lines and weakens through walls, metal, and water. Place your router in a central, elevated location — a shelf in a hallway or living room works better than a corner, a closet, or the floor. Avoid placing it inside a cabinet, behind a TV, or next to a microwave or cordless phone, all of which interfere with the signal.
If your home is large or has thick walls, one router may not reach every room. You can test coverage by walking around with your phone and watching the signal strength. If you see weak signal (one or two bars) in certain areas, those spots will have slow or unreliable connections. Moving the router closer to the center of your home usually helps. If that is not possible, you may need a second router or a WiFi extender, but start by repositioning the one you have.
Check for interference from other devices
WiFi operates on radio frequencies that other household devices also use. Microwaves, cordless phones, baby monitors, and some wireless speakers can interfere with WiFi, especially if they are close to your router. If your connection drops or slows down when you use the microwave, interference is likely the problem.
Move your router away from these devices, or move them away from the router. If that is not practical, you can try changing the WiFi channel your router uses. Most routers have a settings page where you can select a different channel — channels 1, 6, and 11 are the main non-overlapping options on the 2.4 GHz band. Your router's manual will show you how to access these settings. Changing the channel is a trial-and-error process: try one, test your connection for a few minutes, and switch to another if it does not improve.
Update your router's software if the problem persists
Router manufacturers release software updates that fix bugs and improve performance. If you have restarted everything, verified your password, and repositioned your router but still have problems, an outdated software version may be the cause.
Log into your router's settings page using the IP address printed on the router (usually something like 192.168.1.1) or through the router manufacturer's app. Look for a section labeled "Firmware," "Software Update," or "System." If an update is available, follow the on-screen instructions to install it. The router will restart during the update, so plan for a brief loss of internet. Do not unplug the router while an update is in progress.
Frequently Asked Questions
Why does my WiFi work fine sometimes but drop out randomly?
Random dropouts usually mean weak signal, interference from other devices, or an overheating router. Try moving closer to the router to test signal strength. If the connection is stable nearby but drops in other rooms, reposition the router to a more central location. If it drops everywhere, restart the router and check whether a microwave or cordless phone is nearby.
My device says it is connected but I cannot load websites or apps. What is wrong?
The connection to the router is working, but the internet itself is not. Restart your modem by unplugging it for 30 seconds. If that does not work, contact your internet provider to check whether service is down or whether there is a problem with your account.
Can I improve my WiFi speed by changing settings on my router?
You can try changing the WiFi channel to reduce interference, and you can make sure your router's software is up to date. However, speed is mostly determined by your internet plan and how far you are from the router. If you need faster speeds, contact your provider about upgrading your plan.
Should I restart my router regularly to prevent problems?
Restarting once a month can help prevent buildup of temporary errors, but it is not necessary unless you are having problems. If your connection is stable, you do not need to restart regularly.
What is the difference between 2.4 GHz and 5 GHz WiFi?
2.4 GHz travels farther through walls but is slower and more prone to interference. 5 GHz is faster but does not travel as far. Many routers broadcast both at once. If your device supports 5 GHz and you are close to the router, connecting to the 5 GHz network may give you better speed.
