You were downloading a video, game, software update, or media file on Windows, and then this message appeared: “A network error caused the media download to fail part-way.” The file stopped. Maybe it was 80% done. Maybe 10%. Either way, it is frustrating, and you want to fix it fast.
This guide explains exactly what causes this error, how to fix it step by step, and how to stop it from happening again.
What Does This Error Actually Mean?
This error means the connection between your device and the download server was interrupted before the file finished downloading. Windows (or the app you were using) detected the break and stopped the process to avoid saving a broken or incomplete file.
It is not always your fault. The problem can be on your end, the server’s end, or somewhere in between.
Why Does This Error Happen?
Understanding the cause helps you pick the right fix. Here are the most common reasons:
Network-side causes:
- Your Wi-Fi signal dropped or fluctuated mid-download
- Your router disconnected briefly (even for a second)
- Your ISP had a temporary outage or packet loss
- You switched between Wi-Fi and mobile hotspot during the download
System-side causes:
- Windows network adapter reset itself
- Power saving mode put the adapter to sleep
- A VPN or proxy interrupted the connection
- Firewall or antivirus blocked the download mid-way
- DNS failed to resolve mid-session
Server-side causes:
- The download server timed out
- The server had a spike in traffic
- The CDN (content delivery network) had a routing issue
- The download link expired
How to Fix “A Network Error Caused the Media Download to Fail Part-Way” on Windows
Work through these fixes in order. Start simple, then go deeper.
Fix 1: Restart the Download Immediately
Before doing anything else, try restarting the download right away. Many apps (like Microsoft Store, Steam, or browsers) support partial downloads and will resume from where they stopped.
- In a browser, click the download again
- In Microsoft Store, go to Library and click the retry/resume button
- In Steam, right-click the game and choose Resume
If it works, you are done. If not, keep going.
Fix 2: Check Your Internet Connection
A quick check can save you a lot of time.
- Open a browser and load a few different websites
- Run a speed test at fast.com to check for speed drops or packet loss
- If results look weak, restart your router: unplug it, wait 30 seconds, plug it back in
- Reconnect your device to Wi-Fi and try again
If your connection is unstable, switching to a wired Ethernet connection almost always solves the problem. Ethernet is far more reliable than Wi-Fi for large downloads.
Fix 3: Disable VPN or Proxy
VPNs reroute your traffic. If the VPN server has issues, your download can die mid-way.
- Turn off your VPN completely
- Go to Settings > Network and Internet > Proxy and make sure no manual proxy is enabled
- Try the download again without VPN
If the download works without VPN, the issue is with your VPN provider. Try a different server or contact their support.
Fix 4: Reset Your Network Adapter
Windows can develop network stack issues that cause intermittent drops. A reset clears them.
- Open Command Prompt as Administrator (search “cmd,” right-click, run as administrator)
- Type each command and press Enter after each:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /flushdns
ipconfig /renew
- Restart your PC
- Try the download again
This fixes a surprising number of random download failures.
Fix 5: Disable Network Adapter Power Saving
Windows sometimes puts your network adapter to sleep to save power. During a long download, this kills the connection.
- Right-click the Start button and open Device Manager
- Expand Network Adapters
- Right-click your adapter (Wi-Fi or Ethernet) and choose Properties
- Go to the Power Management tab
- Uncheck “Allow the computer to turn off this device to save power”
- Click OK and restart
This is especially common on laptops.
Fix 6: Temporarily Disable Antivirus or Firewall
Security software can interrupt downloads if it suspects the file or blocks the connection.
- Open your antivirus dashboard
- Look for a “disable temporarily” or “pause protection” option
- Also check Windows Defender Firewall: go to Control Panel > Windows Defender Firewall > Turn Windows Defender Firewall on or off
- Temporarily turn it off for private networks
- Start the download
- Re-enable everything once done
Never leave your firewall off for long. This is just a test to find the cause.
Fix 7: Change Your DNS Server
A slow or failing DNS can drop connections mid-download. Google and Cloudflare DNS are faster and more reliable than most ISP defaults.
- Go to Settings > Network and Internet > Change adapter options
- Right-click your connection and choose Properties
- Select “Internet Protocol Version 4 (TCP/IPv4)” and click Properties
- Choose “Use the following DNS server addresses”
- Enter:
- Preferred: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
- Alternate: 8.8.4.4 or 1.0.0.1
- Click OK and retry the download
Fix 8: Update or Reinstall Network Drivers
Outdated or corrupt network drivers cause all kinds of connection problems.
- Open Device Manager
- Expand Network Adapters
- Right-click your adapter and choose “Update driver”
- Select “Search automatically for drivers”
- If no update is found, go to your PC or motherboard manufacturer’s website and download the latest driver manually
After updating, restart your PC and try the download.
Fix 9: Use a Download Manager
If your browser keeps failing, a dedicated download manager handles interruptions much better. Tools like Free Download Manager (available at freedownloadmanager.org) can pause, resume, and retry failed downloads automatically. They also split files into chunks and download them in parallel, making failures less likely.
Fix 10: Check if the Server or Platform Is Down
Sometimes the problem is not on your end at all.
- For Microsoft Store issues, check https://status.microsoft.com
- For Steam, check their status page
- For YouTube or streaming platforms, check Downdetector
- Wait 30 minutes and try again if there is a known outage

Conclusion
The error “a network error caused the media download to fail part-way” on Windows is almost always fixable. Start with the simplest steps: restart the download, check your connection, and switch to Ethernet. If that does not work, reset your network stack, disable power saving on your adapter, and check whether your antivirus or VPN is interfering.
Most people fix this issue within the first three or four steps. The more persistent cases usually involve outdated drivers or power management settings. Work through the list, and you will find the fix.
Frequently Asked Questions
Why does my download keep failing at the same percentage?
This usually points to a corrupted section of the file on the server, a CDN routing issue, or your firewall blocking something in that packet range. Try changing your DNS, use a different network if possible, or contact the platform’s support team with the error details.
Does this error mean my file is corrupted?
Not necessarily. Windows stopped the download to prevent saving an incomplete file. The file on your device may be incomplete, but it is not automatically corrupted. Delete the partial file and restart the download cleanly.
Can my ISP cause this error?
Yes. Some ISPs throttle large downloads or have intermittent routing issues. Run a packet loss test using a tool like PingPlotter to see if your ISP is dropping packets. If it confirms packet loss, contact your ISP or use a VPN to route around the problem.
Why does this only happen on Wi-Fi?
Wi-Fi is unstable compared to wired connections. Even minor signal interference, distance from the router, or network congestion can cause brief disconnections that interrupt downloads. Switch to Ethernet for any download over a few hundred megabytes.
Is there a way to resume a failed download automatically?
Yes. Use a download manager like Free Download Manager or Internet Download Manager (IDM). These tools automatically retry and resume failed downloads without losing progress.
