Can Downloading Slow Down Wi-Fi? (Explained & Solved)

You’ve probably noticed that when you have many devices connected to your Wi-Fi network, the internet runs slow.

The truth is, there are many reasons why this may happen. Downloading can definitely slow down your Wi-Fi speed, but it’s not the only reason behind the slow connection.

In this article, we will answer the question “Can downloading slow down Wi-Fi?” and show you how to possibly solve this problem.

Short Answer To How Downloading Affect Wi-Fi Speed

Downloading can slow down Wi-Fi. A high amount of traffic can slow down your Internet connection, but a poor wireless signal will also affect your speeds. Everyone on a Wi-Fi connection will be affected when one user is downloading large files.

If you’re downloading a large file and notice that your Wi-Fi is slowing down, it’s probably because the router is being overwhelmed by the size of the file.

If you’re downloading multiple files at once or playing an online game while downloading something, you might notice that it takes longer to download.

The same goes for uploading files.

Uploading a large video or image to the cloud? Don’t be surprised if your Wi-Fi slows down.

In general, using your home internet for normal activities should not affect your Wi-Fi speed. This includes:

  • Emailing,
  • streaming Netflix (at normal HD),
  • using social media.
  • etc. 

However, if you have multiple people in your household using the Internet at once, all performing different tasks, it could slow things down.

Note, if you’re using a VPN that might also slow down your Internet.

How Come My Wi-Fi Is Slower When Downloading?

There are a few reasons why your Wi-Fi might be slower when you’re downloading files.

It’s natural to assume that by downloading files, you’re only using the internet, but the opposite is true: you’re actually taking up valuable bandwidth on two networks at once.

When you download files from the internet, they’re transferred from one computer (the server) to another (your computer).

In order for this transfer to happen quickly and efficiently, it needs ample bandwidth on both of these networks.

If some of your bandwidth is being taken up by someone else in your house streaming Netflix, then there isn’t as much left over for your downloads when you have multiple devices downloading at once — or even one device downloading multiple things — your available bandwidth gets split up into smaller chunks and they can take longer to complete.

Downloading is different from streaming because the data isn’t being used immediately—these files are instead stored on your device so that they can be accessed later.

Let’s Take A Look At How Downloading Works

While you may be downloading files on several devices at once, the actual download happens one file at a time on a single device.

So when you’re downloading a TV episode to watch offline, the download goes through only one device—your iPhone or Android phone, tablet, laptop, or desktop computer.

On that particular device, the download might slow down your internet speed. But this has nothing to do with your Wi-Fi connection or router.

That’s because Wi-Fi is a shared network connection: multiple devices connect to the same router and share its available bandwidth.

Can Downloading Directly Affect My Wi-Fi Speed?

When you download anything on your computer—a picture, a song, a video or even an app—you’re using data.

This is true even if you’re downloading something to your phone and not a laptop or desktop. When you use data, it affects your Wi-Fi speed.

If the only thing that’s accessing the internet in your home is one device that’s downloading something, then yes: Downloading can affect your Wi-Fi speed. It won’t make the connection slower; it will just slow down the amount of bandwidth available for other devices on that network.

If you’re streaming a movie on Netflix while someone else is trying to stream YouTube videos, for example, it’s going to be more difficult for both of those streams to work properly (hence why “buffering” messages pop up).

How Do I Check If It Interferes With My Wi-Fi Connection?

One of the easiest ways to check this is to go to a website like and run a speed test. If your speeds are really slow, it could be due to downloading.

Another way is to check your router’s logs for any signs that devices are connecting/disconnecting from the network or if there are any errors.

You can also try unplugging all devices except for one and check again, then try another device and check again.

How Much Bandwidth Does Downloading Use?

Bandwidth is the amount of data that can be transmitted in a fixed amount of time. It refers to how much “stuff” your internet connection can send at once. The more bandwidth you have, the faster your Wi-Fi will be.

One way that downloading can slow down your Wi-Fi is by consuming bandwidth.

Downloading uses a lot of bandwidth because it involves sending large amounts of data over the internet. When you download things, the more data you receive, the more bandwidth you use up in your home network.

The second way that downloading slows down your Wi-Fi is when it causes other devices on the same network to compete for bandwidth—the competition for limited resources results in slower Wi-Fi speeds for everyone involved.

Both types of downloads use up a lot of bandwidth and affect other devices on your home network, which slows down WiFi speed for all connected devices, not just one specific device.

The main difference is that peer-to-peer downloads are usually faster than traditional downloads—but they also require more bandwidth and therefore significantly affect other devices on your home network

Can You Stop Downloading From Interfering With Your Wi-Fi?

It’s not a secret that downloading takes up some of your bandwidth.

That said, downloading is a perfectly normal thing to do with your internet. Everything from videos to text files takes some of your bandwidth when you download them.

So can it be prevented?

Not really: no matter what, downloading will take up some of your bandwidth.

While you can still download all the things that you need and want, keep in mind that if there are other people on your Wi-Fi connection then they will have to share the limited bandwidth with all of them.

This can slow down everything else on the network – if someone is watching Netflix while someone else is downloading a file at full speed (or torrenting or uploading), then both connections will be slower than they would otherwise be.

Is there any way around this problem?
There’s not much you can do about downloads taking up part of your bandwidth.

But there are things you can do to improve your internet connection in general: for example, you could upgrade your package for faster speeds or get a better router.

The best solution would depend entirely on what kind of setup and what kind of usage habits each specific household has.

How To Reduce The Effects Of Downloading On Your Wi-Fi?

If you’re experiencing slow Wi-Fi speeds while downloading, you can take steps to reduce their effect on your internet connection.

Here’s how:

  • Use a download accelerator.
    If a third party is hosting your files, consider using a download accelerator like Internet Download Manager or Free Download Manager.
    These programs use multiple connections to the same server to accelerate downloads.
    This reduces the impact of downloading on other computers connected to your network.
  • Use a download manager.
    Many browsers include free software that assists with downloads, such as the Chrome Downloader or the Firefox Downloader. These programs may be able to increase download speed and make it easier for you to manage multiple files at once.
  • Use a download scheduler.
    If you know when people are less likely to need Wi-Fi in your home, set up a program that schedules large downloads for those times of day or night—for example, after everyone has gone to bed or during school hours!
    This will help prevent congestion and improve network performance overall by decreasing peak usage time periods while increasing off-peak usage time periods (when fewer devices are competing for bandwidth).


We’ve reached the end of this article, and you should now know that downloads can slow down your Wi-Fi connection.

This is because they use a large amount of bandwidth and reduce the amount available for other devices to use. If a lot of people are downloading on your network at once, it can affect the speed of your Wi-Fi.

However, if you are the only one downloading something on your network, it will usually have a limited effect on your Wi-Fi speed.
