If your Steam download speed drops to 0 B/s, your internet connection may not be the problem. Steam sometimes pauses network transfers while it processes downloaded files, installs game data, or updates existing files. However, if the download stops making progress altogether, a connection issue, download setting, or installation error could be responsible.
Before trying random fixes, open Steam’s Downloads page and check whether disk activity or installation progress continues when network speed reaches zero. This simple check can help you decide whether to wait or troubleshoot the problem.
In this guide, you’ll learn how to identify the cause of a Steam download stuck at 0 B/s and which fixes to try first.
Why Does Steam Download Speed Drop to 0 B/s?
Steam downloads and installs game files as part of the same process. Depending on the game and the type of update, the client may need to unpack downloaded data, write files to your drive, or modify existing game files.
When that work takes time, network activity can temporarily fall to zero. This does not always mean the download has failed.
Other possible causes include:
An unstable internet connection or Wi-Fi interference.
A busy hard drive or SSD that is struggling with the current workload.
A Steam download speed limit or scheduled download restriction.
A slow or unreliable download region.
A problem with Steam’s download cache.
Insufficient storage space or a disk write error.
The best way to identify the cause is to check Steam’s current activity before changing its settings.
1. Check Whether Steam Is Still Downloading
Start with Steam itself. A download speed of 0 B/s does not necessarily mean that the entire process has stopped.
Follow these steps:
- Open Steam on your PC.
- Select Downloads from the bottom of the client, or open View > Downloads.
- Find the game that is downloading or updating.
- Check the network activity, disk activity, and installation progress.
- Wait briefly and see whether the progress changes.
Pay attention to what happens when the network speed drops to zero.
- Disk activity continues and installation progresses: Steam may be processing or writing game files. Give it time to finish.
- Network speed repeatedly drops while disk activity remains high: Your storage drive or another disk-intensive task may be contributing.
- Network, disk activity, and progress all stop: Check the displayed status and continue with the troubleshooting steps below.
- Steam displays an error: Follow the fix that matches the specific error instead of treating it as a normal download pause.
Do not judge the problem by the network graph alone. Check whether the game is actually making progress.
2. Check Your Disk and CPU Usage
If Steam repeatedly drops to 0 B/s during installation, your PC’s storage drive or processor may be busy handling game files.
Windows Task Manager can help you check whether Steam or another application is using too many system resources.
To check your PC:
Keep Steam open while the download is running.
Press Ctrl + Shift + Esc to open Task Manager.
Open the Processes tab.
Check the CPU and Disk columns.
Look for Steam or another application using significant resources.
If Steam is using the disk heavily and installation progress continues, allow it to finish. If another application is performing a large file transfer, backup, or update, let it finish if possible and check Steam again.
An older HDD may take longer than an SSD to process certain game installation workloads. However, a busy drive does not automatically mean it is faulty, and an SSD can also experience slowdowns.
When to move on: If Steam shows no meaningful progress, disk activity is low, or an error appears, continue with the following fixes.
3. Check Steam’s Download Settings
A download restriction or gameplay setting may explain why Steam is not downloading as expected.
Open Steam > Settings > Downloads and check the following options.
Check the download speed limit
Look for Limit download speed. If a limit is enabled, it may restrict how quickly Steam downloads game files.
Disable the limit for testing, or adjust it if you intentionally want to reserve bandwidth for other applications.
Valve’s official Steam download speed settings guide explains where to find this option.
Check download scheduling
If your Steam client displays a scheduled download option, make sure the current time falls within the permitted download period.
Check downloads during gameplay
If downloads stop when you launch a game, Steam may be configured to pause them during gameplay.
Check the relevant gameplay download setting in Steam’s Downloads preferences. Change it only if you want downloads to continue while playing.
Resume the download and watch its progress before trying another fix.
4. Restart Steam and Check Your Internet Connection
If the download is genuinely stuck, a restart is a sensible next step.
Pause the affected download.
Exit Steam normally using the Steam menu.
Open Steam again and resume the download.
If the problem remains, restart your PC and test again.
Next, check whether your internet connection is working normally.
Open a few websites or test another download.
If you’re using Wi-Fi, move closer to the router or test a wired connection if possible.
If other downloads also fail, investigate your internet connection before focusing only on Steam.
If other services work normally but Steam remains stuck, continue with Steam-specific troubleshooting.
Avoid repeatedly force-closing Steam while it is actively writing game files. Exit the client normally whenever possible.
5. Change Steam’s Download Region
Steam uses regional content servers to deliver game files. A server in your selected region may sometimes experience slowdowns or connection problems.
Testing another nearby region can help determine whether the current server is contributing to the issue.
Follow these steps:
Open Steam > Settings > Downloads.
Find Download Region.
Note your current region.
Select a different nearby region.
Restart Steam if needed, then resume the download.
Check whether the download becomes more stable. If the alternative region makes no difference, switch back to your original selection.
Do not assume that a distant region will always be faster. The best result depends on the server and your connection.
You can also consult Steam’s official slow-download troubleshooting guide for additional connection checks.
6. Clear Steam’s Download Cache
If the previous fixes do not help, clearing the download cache is worth trying. Steam’s official troubleshooting guidance recommends this for certain download and installation problems.
Before proceeding, make sure you know your Steam login details and can complete Steam Guard authentication if required.
Here’s how to clear the cache:
Open Steam > Settings > Downloads.
Find Clear Download Cache.
Select the option and confirm your choice.
Follow any prompts to sign in to Steam again.
Open Downloads and resume your game.
Clearing the download cache does not normally remove your installed games, but Steam may require you to sign in again.
Check whether the download resumes normally. If the same problem returns, investigate the installation drive or any error displayed by Steam.
7. Fix Disk Write Errors and Installation Problems
If Steam displays a message such as Disk Write Error or An error occurred while updating, the issue may involve the installation drive, folder permissions, or game files.
These errors need different troubleshooting from a temporary drop in network speed.
Check available storage space
Open File Explorer and select This PC. Check the drive where the game is being installed.
If space is running low, remove unnecessary files or move suitable files to another drive. Make sure there is enough free space for the game’s download and installation requirements.
Repair the Steam library folder
If Steam cannot write files to the library folder, repairing it may help.
Open Steam and go to Settings > Storage.
Select the drive or library containing the affected game.
Open its additional options menu, usually shown as three dots.
Select Repair Folder or the equivalent repair option available in your client.
The exact interface may vary by Steam version. Valve lists library-folder repair among its recommended installation troubleshooting steps.
Verify the game files
If the issue affects an installed game update, verifying its files may help identify damaged or missing data.
Open your Steam Library.
Right-click the affected game and select Properties.
Open Installed Files.
Select Verify integrity of game files, if available.
Wait for the verification process to finish.
File verification is useful for game-file problems, but it is not a general fix for every download slowdown.
For more guidance, visit Steam’s official Update and Installation Issues page.
How to Tell If Your Steam Download Is Fixed
After applying a fix, return to Steam’s Downloads page and check whether the game makes progress.
What you notice | What it means |
|---|---|
Downloaded data increases | Steam is transferring data successfully |
Network speed reaches zero, but installation continues | Steam may be processing or writing files |
Download resumes after changing regions | The previous download route may have contributed |
Download completes without errors | The immediate problem is resolved |
Download repeatedly stops with an error | Further troubleshooting is needed |
Test one change at a time where possible. This makes it easier to identify what helped instead of changing several settings without knowing which one mattered.
If the problem persists, note the affected game, installation drive, error message, and fixes you’ve already tried. These details can help when consulting Steam Support.
Conclusion
When Steam download speed drops to 0 B/s, check installation progress and disk activity before changing anything. Steam may simply be processing game files rather than experiencing an internet problem.
If the download genuinely stops, check your download restrictions, restart Steam, test your connection, and try another download region. Clearing the download cache or repairing the library folder may help when simpler checks fail.
The goal is not to maintain a perfectly steady download-speed graph. It is to identify what is stopping progress and get your game downloaded and installed successfully.
Frequently Asked Questions
Why does my Steam download speed drop to 0 B/s but then start again?
Steam may temporarily stop receiving data while processing downloaded files or installing an update. If the installation continues and the download resumes, the pause may be normal. If all progress repeatedly stops, investigate the connection, download settings, and installation drive.
Does Steam download speed dropping to zero mean my internet is disconnected?
No. Steam may pause network transfers while working on game files. Check other internet services and Steam’s disk activity before assuming your connection has failed.
Can an HDD cause Steam downloads to stop?
An HDD can slow certain installation and update operations, particularly when it is busy handling many files. However, storage speed is only one possible cause. Check Task Manager and Steam’s progress before deciding that the drive is responsible.
Will clearing Steam’s download cache delete my games?
Clearing the download cache does not normally remove installed games. However, Steam may ask you to sign in again. Make sure you can access your account before proceeding.
Why does my Steam download stop when I launch a game?
Steam may be configured to pause downloads while you play. Check the download settings for the option that controls downloads during gameplay and adjust it if needed.
