speed test will only ever show the available bandwidth, so if you are on a 10Mb line, and you have a device using 4Mbps, then the speed test result will show up as approximately 6Mbps remaining.
Please make sure that there are no applications running when you do the test. This will include any PC’s or devices such as mobile phones, tablets or pc’s connected to the network as they could be downloading updates in the background.
Where possible please perform the speed test while connected to the router via LAN cable. Using a wireless device will not give you an accurate result as it is prone to interference. Please ensure the router is not placed near the microwave, cordless phones, fridge or any device that uses the same frequency. Having multiple wireless devices connected at the same time can also influence the outcome of the speed test as can your distance from the router.
Test at different times of the day, running multiple tests to obtain an average. Available bandwidth on the network can differ at certain times of day.
Please note that speed test servers can themselves also experience congestion if they receive multiple requests at the same time from multiple users which will ultimately affect the result.
Please note that there is a difference between Mb and MB – 10Mb = 1MB (1.25MB). Network speeds are measured in Mbps while download speeds are measured in MBps
