Start with the simplest fixes first

Most wireless internet problems go away after restarting your router — the box that broadcasts your Wi-Fi signal. Unplug it from power, wait 30 seconds, and plug it back in. This clears temporary errors that build up over time and usually takes less than two minutes. If your connection returns to normal, you are done.

If restarting does not work, check whether your device is actually connected to your network. On Windows, click the Wi-Fi icon in the bottom right corner of your screen. On Mac, click the Wi-Fi icon in the top right corner. You should see your network name listed and marked as "Connected". If it shows "Not Connected" or you see a different network name, click your own network and enter your password again.

The password is usually printed on a sticker on the bottom or back of your router. If you changed it and cannot remember it, you can reset the router to factory settings by holding a small button (usually recessed) on the back for 10 to 15 seconds. This erases your password and returns everything to the default, so you will need to set it up again from scratch.

Key Takeaways

  • Restart your router by unplugging it for 30 seconds, which fixes most temporary connection problems without any other action.
  • Check that your device is actually connected to your network name, not a neighbour's or a saved network from the past.
  • Move your router to a central, elevated location away from walls, metal objects, and other electronics that block the signal.
  • If your internet is slow everywhere in your home, the problem is usually your router or your internet service itself, not your device.
  • Restarting your modem (the device your router plugs into) fixes problems that come from your internet service provider's connection.

Move your router to a better location

Wireless signals travel in straight lines and bounce off hard surfaces. They do not pass through metal, water, or thick walls well. If your router sits in a closet, inside a cabinet, or behind a TV, move it to an open shelf in a central room — ideally elevated rather than on the floor. A hallway or living room usually works better than a bedroom corner.

Keep your router away from microwaves, cordless phones, baby monitors, and other wireless devices. These all use the same radio frequencies and interfere with each other. Metal objects like filing cabinets, refrigerators, and radiators also block the signal. If your router must sit near a metal object, angle it so the antenna points away from the metal.

Test your connection in different rooms. If it is strong in the kitchen but weak in the bedroom, your router is too far or blocked by walls. Moving it closer or to a more central location usually solves this. If the signal is weak everywhere, the problem is not location — move to the next section.

Restart your modem if the internet itself is down

Your modem is the device that connects to your internet service provider. Your router plugs into the modem. If your modem is not working, your router has no internet to broadcast, even though it may still show as "connected" on your device.

To restart your modem, unplug it from power, wait 30 seconds, and plug it back in. Wait another two to three minutes for it to fully restart — you will see lights on the front stop blinking and settle into a steady pattern. Then restart your router the same way. This order matters: modem first, then router.

If the modem does not come back online after five minutes, check that the cable from the wall outlet is plugged firmly into the port labeled "In" or "Internet" on the modem. If it is loose, push it in until you hear a click. Also check that the power cable is plugged in. If everything is connected and the modem still will not start, contact your internet service provider — the problem is on their end.

Check for too many devices or bandwidth-heavy activity

If your internet is slow but connected, the problem may be that too many devices are using the network at once, or one device is using most of the bandwidth. Streaming video, downloading large files, and online games all use a lot of bandwidth. If someone in your home is streaming video while you are trying to work, both of you will experience slowness.

Disconnect devices you are not using. Turn off Wi-Fi on phones, tablets, and laptops that are sitting idle. Ask others in your home whether they are downloading or streaming. If they are, ask them to pause or wait until you are finished. If the internet speeds up, your router is working fine — you just need more bandwidth or a different plan from your internet service provider.

You can also restart your router again. Over time, routers can become sluggish if they have been running for weeks without a restart. Unplug it for 30 seconds, plug it back in, and test your speed after it fully restarts.

Update your router's software or change the Wi-Fi channel

Routers have software that controls how they work. Manufacturers release updates to fix bugs and improve performance. To update your router, open a web browser and type the router's IP address into the address bar — this is usually 192.168.1.1 or 192.168.0.1, printed on the sticker on your router. Log in with the username and password (also on the sticker, usually "admin" and "admin" or "admin" and the Wi-Fi password).

Look for a section called "Administration", "System", or "Settings" and find the option to check for updates. If an update is available, read and install it. This can take several minutes. Do not unplug the router during an update.

If updating does not help, your router may be broadcasting on a Wi-Fi channel that is crowded with signals from neighbouring networks. Most routers automatically choose a channel, but you can change it manually in the same settings area. Look for "Wi-Fi Channel" or "Channel Selection" and try changing from the automatic setting to channel 1, 6, or 11 (these do not overlap with each other). Restart your router and test the connection.

When to contact your internet service provider

If you have restarted both your modem and router, moved your router to a better location, and the internet is still slow everywhere in your home, the problem is likely with your internet service itself, not your equipment. Contact your internet service provider and describe what you have already tried. They can run a test on their end to see whether the connection is working at full speed.

Also contact your provider if your modem will not restart, if the lights on the modem stay red or off after five minutes, or if you have no internet at all. These are signs that the problem is between the wall outlet and the modem, which is the provider's responsibility.

Have your account number ready when you call. The provider may ask you to restart your modem again while you are on the phone, or they may send a technician to check the connection at the wall outlet.

Frequently Asked Questions

Why does my Wi-Fi work in some rooms but not others?

Walls, especially thick ones or those with metal studs, block wireless signals. Distance also matters — the farther you are from the router, the weaker the signal. Move your router to a more central location or closer to the rooms where you need it most. If that is not possible, a Wi-Fi extender can boost the signal in distant rooms.

Should I restart my router every day?

No, you do not need to restart it daily. Restart it only when your connection drops or slows down, or if you have not restarted it in several weeks. Most routers are designed to run continuously without a restart.

What is the difference between Wi-Fi and internet?

Internet is the service you pay for from your provider. Wi-Fi is the wireless signal your router broadcasts. You can have internet without Wi-Fi (by plugging a device directly into the modem with a cable), but you cannot have Wi-Fi without internet. If your Wi-Fi is working but you have no internet, the problem is with your modem or service provider, not your router.

Can I improve my Wi-Fi speed by buying a new router?

Only if your current router is very old (more than five years) or damaged. A new router will not make your internet faster if your service plan does not support higher speeds. Contact your provider to find out what speed you are paying for, then test your actual speed using a free online speed test. If your actual speed matches your plan, a new router will not help.

Why does my connection drop at certain times of day?

This usually means too many devices are using the network at the same time, or someone is running a bandwidth-heavy task like downloading or streaming. It can also mean your router is overheating — make sure it has space around it and is not in direct sunlight or near a heat source. If it drops at the same time every day, ask others in your home what they are doing online at that time.
