How can I troubleshoot slow downloads or connections within Steam?
Internet and other network connection speeds are typically measured in multiples of bits per second. However, Steam downloads, like many other file downloads, are measured in multiples of bytes per second. A byte is a group of 8 bits.
To compare your Steam download speed to your connection speed, multiply your Steam download speed by 8. For example, if you are getting 768KB/s (kilobytes per second) as your Steam download speed, you are getting 6144Kb/s (kilobits per second) or 6 megabits per second download speed according to most Internet service providers.Example download speed conversions
|Advertised Connection Speed||Est. Max Steam Download Speed|
|3 megabits/second||384 KB/S|
|5 megabits/second||640 KB/S|
|15 megabits/second||1.9 MB/S|
|20 megabits/second||2.5 MB/S|
|30 megabits/second||3.75 MB/S|
|50 megabits/second||6.25 MB/S|
The speed displayed in your System Tray or network connection properties is typically the speed you are connected to your local area network (LAN) and does not represent the speed you are connected to the Internet at. Please refer to the materials for your connection plan or contact your Internet service provider (ISP) for information on your connection speed. You can also use one of the numerous speed testing sites available online such as SpeedTest or DSLReports to test your connection speed.
Steam uses content servers that are located all over the world. Steam attempts to select the best content server based on your location. If Steam downloads are going slower than expected, please double check your current download region:
Some third-party applications such as ESET NOD32 Anti-Virus can cause Steam to use incorrect content servers. Any sort of Internet security and/or packet filtering software may have a similar affect. This can also lead to connection issues.
If you are not using NOD32 but a different program might be causing the issue, please follow the Programs Which Interfere with Steam guide to test the issue.
For NOD32, there is a work-around that may help:
Please follow these directions to make sure the correct ports are open and double check the list of ISP's that are known to have issues with Steam: Troubleshooting Network Connectivity.
Ensure that your Steam connection rate is set appropriately. For more information, please see Setting Client Rates.
