Hi David, this is Bryll
Thank you for writing us here in Microsoft Community.
Please consider in checking on this link for limitations of OneDrive related to downloading of files: Download files and folders from OneDrive
To identify the source of the issue, a few questions we need to ask:
- Is the problem the same when connecting to a different internet network like a mobile data internet?
- Do you experience the same 1 MB/s download speed on other platforms or websites, or is it only on OneDrive?
- Are you facing issues with download all files or just specific ones?
- What is the size and file type you are trying to download?
- How do you download files in OneDrive, is it via OneDrive.com on the web or OneDrive desktop client?
- What is the username domain of your OneDrive account? Is it @Gmail @Outlook or work/school domain of the company?
- Are you using a personal OneDrive or a work/school SharePoint?
There are several potential reasons why your upload speed might be faster than your download speed:
- Asynchronous connection:
- Most internet plans are asymmetrical, meaning they offer a higher download speed and lower upload speed. This is because typical internet usage involves more downloading then uploading.
- Network congestion:
- During peak hours, your neighborhood or ISP network might be congested, causing the download speeds to slow down while upload speeds remain unaffected. This is similar to a traffic jam on highway, where it is easier to send data out than receive it.
- Bandwidth throttling:
- Some ISP's might throttle download speeds during specific activities. This can also lead to a disparity between upload and download speeds.
- Background applications:
- Certain applications running in the background might be using up more download bandwidth than you realize, leading to slower download speeds.
While we wait for your answers to our questions, try these strategies in a sequential manner:
- Try using a different internet environment or connection. If your mobile phone's internet data is strong and stable, try to check its download speed for OneDrive and other platforms or website.
- Make sure your antivirus software, VPN or firewall is not blocking or slowing down OneDrive.
- Try using a different browser or an incognito window to access OneDrive and download the folder. You can also download the folder in smaller batches instead of as a single zip file.
- Check your OneDrive settings and make sure the download rate is not limited. You can find this option in the Network tab of the OneDrive settings.
Should problem remain, we will recommend other strategies once we receive your response to our questions. If possible, please share some screenshots or video of the problem.
Yours truly,
Bryll
