What actually slows down your internet

Your internet speed depends on three things: what your provider is sending you, what your equipment is doing with it, and what else is using the connection right now. Most people blame their provider when the real problem is one of the other two. Before you call them, check whether your router is in the right place, whether something is downloading in the background, and whether your device is too far from the wireless signal.

Speed tests measure what reaches your device in that exact moment. If you run one while someone else is streaming video, the test will show a slower speed than you actually pay for. This is normal and not a problem with your service — it just means the connection is being shared. The real question is whether you have enough speed for what you actually do.

Key Takeaways

  • Restart your modem and router by unplugging them for 30 seconds, which fixes most speed problems without any other work.
  • Move your router to a central, elevated location away from walls and metal objects, since distance and obstacles slow wireless signals significantly.
  • Check what is using your connection right now — streaming, downloads, and video calls all compete for the same bandwidth.
  • Run a speed test on a device close to your router to see whether the problem is your wireless signal or your actual service.
  • If your speed is consistently lower than what you pay for, contact your provider with the test results and ask them to check your line.

Restart your modem and router

Unplug your modem (the device that connects to your wall outlet and your provider's network) and your router (the device that broadcasts wireless signal) for at least 30 seconds. Plug the modem back in first and wait for the lights to stop blinking and settle into a steady pattern — this usually takes two to three minutes. Then plug in the router and wait another two to three minutes for it to fully start up.

This clears the temporary memory both devices use and forces them to reconnect to your provider's network fresh. It fixes slow speeds about half the time, especially if you have not restarted in several weeks. After the restart, run a speed test to see whether things improved. If they did, you are done. If not, move to the next step.

Check what is using your connection

Open the Settings app on your device and look for a section called Network, Internet, or Data Usage. This shows you what programs are currently downloading or uploading. Common culprits are Windows Update, cloud backup services like OneDrive or Google Drive, and streaming services running in the background. Close or pause anything you are not actively using.

If you share your internet with other people, ask whether anyone is streaming video, playing online games, or downloading large files. These activities use most of your available speed. If someone is doing one of these things, your own speed will be noticeably slower until they finish. This is not a problem — it is how shared internet works. If the slowness happens even when no one else is using the connection, the issue is with your service or your equipment.

Move your router to a better location

Your router broadcasts a wireless signal in all directions, but walls, metal objects, and distance weaken it. Place your router in a central location in your home, elevated off the floor (on a shelf or mounted on a wall), and away from metal filing cabinets, microwaves, and thick walls. If your router is in a back corner or inside a cabinet, moving it to an open, central spot can noticeably improve speed.

Wireless signal gets weaker the farther you are from the router. If you are in a different room or on a different floor, your speed will be slower than it would be standing next to the router. This is normal. If you need fast speed in a room far from your router, consider moving the router closer, using a mesh system (multiple small routers that work together), or running an ethernet cable from the router to that room.

Run a speed test near your router

Visit speedtest.net or fast.com on a device (phone, tablet, or computer) and stand within a few feet of your router. Run the test and write down the download speed. This tells you what your actual service is delivering. Compare it to the speed your provider says you are paying for — you can find this on your bill or by logging into your account online.

If the speed test shows close to what you pay for, your service is working correctly and the slowness you feel is either because something else is using the connection or because you are far from the router. If the test shows significantly less than what you pay for — for example, you pay for 100 Mbps but the test shows 30 Mbps — then something is wrong with your service or your equipment.

Contact your provider if the problem is your service

If your speed test near the router shows less than 50 percent of what you pay for, contact your provider's support line. Have your speed test results ready and tell them the exact numbers. Ask them to check whether there is a problem with your line or your modem. They can often see this from their end without you doing anything.

Providers sometimes throttle (intentionally slow down) your connection if you have used a very large amount of data in a month, though this is less common than it used to be. Ask whether you have hit a data limit. If you have, the slowness will return to normal after your billing cycle resets. If you consistently use a lot of data and want faster speeds, you may need a plan with a higher data limit or a different type of service altogether.

Consider your device and browser

Older devices and browsers sometimes cannot use the full speed your connection offers. If you are using a phone or computer more than five years old, or if you are using an older version of your browser, update to the latest version. This is especially true for wireless devices — older phones and laptops have older wireless technology that is slower than what newer equipment supports.

If you are using a wired connection (ethernet cable directly from router to device), you should see faster and more stable speeds than wireless. If you are having trouble with wireless speed, try plugging in with an ethernet cable to see whether the problem is your wireless signal or your actual service. If the wired speed is fast but wireless is slow, your router placement or an older device is the issue.

Frequently Asked Questions

How often should I restart my modem and router?

Restart them once a month as routine maintenance, or whenever you notice your speed has dropped. If you need to restart more than once a week to get normal speeds back, contact your provider — something may be wrong with your equipment or line.

Will upgrading to a faster plan actually make things faster?

Only if your current speed test shows you are getting less than what you pay for. If you are already getting the speed you pay for but want faster speeds, then yes, upgrading will help. If you are not getting what you pay for, upgrading will not fix it — the problem is with your service, not your plan.

Is it better to use wireless or plug in with a cable?

Wired connections (ethernet cables) are faster and more stable than wireless. If you need the fastest possible speed for something important like a video call or online game, plug in with a cable. For everyday browsing and email, wireless is fine if your router is reasonably close.

What speed do I actually need?

For one person browsing and checking email, 10 to 25 Mbps is enough. For streaming video, you need 5 to 25 Mbps depending on quality. For multiple people using the internet at once, 50 to 100 Mbps is more comfortable. Online gaming needs less speed than you might think — usually 5 to 10 Mbps — but needs a stable connection.

Can I speed up my internet without calling my provider?

Yes, if the problem is your router placement, what is using your connection, or your device. Restart your modem and router, move the router to a better spot, close programs that are downloading, and run a speed test near the router. If the test shows you are getting what you pay for, you have fixed it. If not, you will need to contact your provider.
