An error may result from having the speed test open in more than one browser tab or window. Please try again later. To prevent this error, and get the most accurate test results, close all other browser tabs and windows before running. If you continue to get a socket error message, or another type of error message, please provide feedback by emailing us at speedtestfeedback fusionconnect.
Why is the location I usually pick missing from the City list? We first complete a latency test to our servers, and if a server does not respond within a specified time frame, it is not included in the City list. A slow response can be caused by latency or packet-loss between the client and server, or particularly high Internet usage during peak hours. Do try the test again in a little while. In which browsers does the Speed Test work best? For best results, use the most recent version of your favorite browser.
If you are unable to see Speed Test, though other content appears on the speed test page, check your browser's security setting. Try lowering the setting from High to Medium-High, or even a bit lower, to allow the broadband test application to load.
In some cases, firewall and security software can prevent the test from running and generate a "could not connect" error. Temporarily lowering the severity should allow the broadband test to run. Be sure to turn it back on before leaving our website. Our Speed Test automatically detects the optimal server host location for testing, which is not necessarily the closest server host.
This is due to real-time network circumstances like number of hops, or current traffic load on each test server. Change the selection using the Change City drop down function directly underneath the Start Test button. Why is my speed lower than expected? Several factors may slow your connection, resulting in lower-than-expected speeds. Try these simple suggestions below. But if your slower speeds persist, contact your broadband service provider to see if they can determine the issue.
There are many factors that impact your speed test results. Throughput problems in your local area network, IP or access overhead, and network design all play a role. Please read the definitions and examples below to learn more about these factors. An Example of Throughput You have Ethernet 8. But it will actually take longer as the total information that needs to be transmitted is more than 1MB.
The total information is called Payload. The channel needs to not only transmit the payload but also some addressing details like where it is coming from and where it is destined to. The device that sends this email will break down the message into smaller pieces and package them into what are called IP Packets.
The size of these packets is usually determined by your Local Area Network. Some have smaller size, so the message will take more IP Packets to transmit; while others may have larger size which needs fewer IP Packets. This is where the information like the source IP Address, the destination IP Address and additional information about the payload is included. IP Header is usually 20 Bytes Bits long. And that 1MB message will have to be broken down into 10, payload pieces.
Again multiple connections are opened to the test server. Instead of downloading a file, a large file of random data is created on your device and pushed through all connections to the server.
Pushing the data to the server over the network via multiple streams ensures that the maximum throughput is measured.
Again, recording the data throughput against time yields the available internet speed for uploading data. During the ping test, the device sends a small data package over the network to the test server on the internet.
When the server receives this package, it will send it back to the device, completing the roundtrip. The time it takes the data package to complete the roundtrip is called latency, also known as ping. To achieve an accurate reading, multiple ping tests are conducted consecutively, with the final result being the average of all these tests.
All these are automatically handled for you when using Speedcheck. But you should take one crucial aspect into account to test speed accurately. Choose the right tool. This depends on the device you want to use, being a phone or tablet, or a computer.
To check internet speed on a computer, use your browser and the app on this website. To achieve accurate results on mobile devices, you should download our iOS or Android app, respectively. Gbps Gigabits per second. Faster connections are measured this way. GBps Gigabytes per second. No currently operating consumer networks utilize this measurement. Bandwidth You can think of bandwidth as the total capacity a given network has in terms of data.
During certain times of peak traffic, you may experience slower speeds. Throughput Throughput is very similar to bandwidth, in that it is a measurement of the amount of data that passes from one point to another within a certain amount of time. Unlike bandwidth, however, this is a measurement of volume, not speed. Ping Ping simply refers to a signal that is sent from a given device to a server, and back again. This measurement is reflected as latency on a network.
Not necessarily. There are many reasons why you may not be getting the results you expected from your speed test. Once again, make sure you run the test multiple times to rule out any random dips in speed.
Also be sure to double check that no one else is using their device on your network when you run the test. Even a single smartphone can measurably alter your results if it is downloading a large update or streaming content at the same time as your speed test.
Our first recommendation is always to contact your service provider directly for help. They will be able to alert you to any network outages or other issues in your area, and can often troubleshoot your individual connection over the phone or via a live chat service.
Disconnect any VPN service that could be effecting your connection during tests. If it does help, you may be experiencing signal issues with your WiFi.
