Which Speed Test

The speed test has been built to test broadband download speeds up to - and above - 100Mbps. It works with the UK's fastest broadband services, including Virgin Media, BT Infinity and fibre.

Upload Speed is the second basic value that you will get when you perform a speed test. Just like the download speed, the upload speed is also measured in Mbps. Upload Speed means that how fast your internet can upload data to the Internet. Google Fiber, RCN, and Verizon have the fastest tested internet speeds in the US, according to our fastest internet providers 2020 report, which is based on more than 2.4 million results from our internet speed test. Xfinity also offers fast internet speeds, and it performs well in every tested region in the country.

Our free to use speed test gives an accurate calculation of the speed of your internet connection at the time the test was taken. The test uses the most modern methodology rigorously tested over a number of years of development and has been shown to be accurate from low speed (sub 1 Mbps) through to high speed (over 7 Gigabites Per Second) connections.

Any speed test is a 'snapshot' of the speed of the internet connection at the particular time the broadband speed test is run. There are a number of interconnecting elements that will affect the result of the speed test, including the processor load on the computer, the load on your home network, the load on the local exchange, the load on your ISP and the load on the speed test Servers.

To get the most accurate result it is recommended that the test is taken on a device connected by wired ethernet cable to the router. However, this is not always realistic as most people and devices connect to the router (hub) via WiFi. So if the test is being run over WiFi it is recommended that the device is in the same room as the router and the device WiFi strength indicator shows the maximum connection to the router.

It is also recommended that in order for the test result not be affected by other the devices the network that it ensured that no other devices are performing high bandwidth actions such as playing games, watching BBC iPlayer or downloading data files (such as photos, movies, applications, etc). Also look out for software updates (such as Windows Update) running as these can consume a large amount of bandwidth.

Differing times of the day can produce different speed test results as there may be more users of the internet via the local exchange depending on the time of day. eg late afternoon as children come home from school and start using their home internet connection.

Additionally, some older computers and mobile devices may not be able to achieve the maximum possible speed of the internet connection. This can be down to older CPU's or limited network interfaces - some older generation network interfaces will be limited to 100 Mbps.
