Start with the simplest fixes first

Most WiFi problems go away after restarting your router and the device that won't connect. Unplug your router from power, wait 30 seconds, and plug it back in. While it restarts (usually 2 to 3 minutes), restart your phone, laptop, or tablet by turning it off and back on. This clears temporary glitches in both devices' memory and forces them to reconnect from scratch.

If that does not work, move your device closer to the router. WiFi signals weaken with distance and through walls, especially thick ones or those with metal pipes inside. If your device connects reliably when close but drops when you move away, the problem is signal strength, not a broken connection.

Key Takeaways

  • Restart your router by unplugging it for 30 seconds, then restart the device that will not connect — this fixes most temporary WiFi problems.
  • Move closer to the router to test whether the issue is weak signal or a broken connection.
  • Check that your device is connected to the correct network name (SSID) and that you entered the password correctly.
  • If your router is old or overheating, it may need replacement or better ventilation.
  • Interference from microwaves, cordless phones, and neighboring networks can disrupt WiFi on the 2.4 GHz band.

Verify you are connecting to the right network

Your router broadcasts a network name, called an SSID, that appears in your device's list of available networks. Make sure you are selecting the correct one — if you live in an apartment or near other homes, you will see multiple names. The SSID is usually printed on a sticker on your router itself.

Once you select the network, your device will ask for the WiFi password. Type it exactly as it appears on the router sticker, including capital letters and numbers. Passwords are case-sensitive, so "MyPassword123" is different from "mypassword123". If you are unsure whether you typed it correctly, delete the saved network from your device and reconnect, entering the password slowly and carefully.

Check whether your router is overheating or too old

Routers generate heat and need air circulation. If your router is in a closed cabinet, under a bed, or stacked under other electronics, it may overheat and drop connections. Move it to an open shelf or desk where air can flow around it. Feel the router after it has been on for an hour — it should be warm but not hot enough to be uncomfortable to touch.

If your router is more than 5 to 7 years old, it may simply be wearing out. Routers have a lifespan, and older models often lose the ability to hold a stable connection. If restarting and moving it do not help, and your device connects fine to other networks, the router itself may need replacement.

Reduce interference from other devices and networks

WiFi on the 2.4 GHz band (the older, slower standard) shares the same radio frequency as microwaves, cordless phones, baby monitors, and Bluetooth devices. If you use any of these near your router, they can jam the signal. Move your microwave, cordless phone base, or other wireless devices away from the router, or use them less frequently while you are trying to connect.

You can also check whether neighboring networks are crowding your channel. On Windows, open Command Prompt and type netsh wlan show networks mode=Bssid. On Mac, hold Option and click the WiFi icon in the menu bar. Look for other networks nearby and note which channels they use. If many networks use the same channel as yours, log into your router's settings (usually by typing 192.168.1.1 in a web browser) and switch to a less crowded channel.

Forget the network and reconnect from scratch

Sometimes your device remembers incorrect settings from a previous connection. On most phones and tablets, go to Settings, find WiFi, and look for your network name in the list of saved networks. Tap it and select "Forget" or "Remove". Then search for the network again and reconnect, entering the password fresh.

On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, find your network, and click "Forget". On Mac, go to System Preferences > Network > WiFi > Advanced, select your network from the list, click the minus button, and click OK. Reconnect to the network as if it were new.

Update your router's firmware or reset it to factory settings

Router manufacturers release firmware updates that fix bugs and improve stability. Log into your router's settings page (usually 192.168.1.1 or 192.168.0.1 — check the sticker on the router) and look for an Administration, System, or Settings section. If an update is available, install it and let the router restart.

If nothing else works, you can reset the router to its original factory settings. This erases all your saved settings, so you will need to set up the network name and password again. Most routers have a small reset button on the back that you hold down for 10 to 15 seconds with a paperclip or pen. After the reset, the router will restart and you can set it up as if it were new.

Check your internet service and contact your provider if needed

A working WiFi connection does not always mean you have internet. Your router may connect fine but have no signal from your internet service provider. Check whether the lights on your router show a connection to the internet — usually a light labeled "Internet", "WAN", or "Online" that is solid green or blue. If that light is off or red, restart the modem (the device that connects to your internet line) by unplugging it for 30 seconds.

If the modem light does not come back on, or if multiple devices connect to WiFi but none can reach the internet, contact your internet service provider. There may be an outage in your area, or the line itself may be damaged. Your provider can check the signal on their end and send a technician if needed.

Frequently Asked Questions

Why does my WiFi work fine sometimes but drop randomly?

Random drops usually mean weak signal, interference, or an overheating router. Try moving closer to the router or moving it to a more central location in your home. If the problem happens at certain times of day, interference from a microwave or cordless phone is likely — move those devices away from the router.

Can I use my phone's hotspot instead of fixing the WiFi?

Yes, but phone hotspots use your cellular data and are usually slower than WiFi. If you have a limited data plan, using hotspot instead of WiFi will count against your monthly limit. It is a temporary workaround, not a long-term solution.

What is the difference between 2.4 GHz and 5 GHz WiFi?

2.4 GHz is older and slower but travels farther and through walls better. 5 GHz is faster but does not reach as far. Many modern routers broadcast both at once. If your router offers both, try connecting to the 5 GHz network if you are close to the router, or 2.4 GHz if you are far away.

Should I leave my router on all the time?

Yes, routers are designed to run continuously. Turning it off and on repeatedly can shorten its lifespan. The only reason to unplug it is to restart it when you have connection problems.

How do I know if my router is broken or if it is just the WiFi?

Plug an ethernet cable directly from the router to your computer. If the internet works through the cable but not through WiFi, the router's WiFi hardware is the problem. If the internet does not work even through the cable, the router itself or your internet connection is broken.
