Secondly, IP packets don’t only contain useful ‘payload’ information and also contain headers about the information sent. This is because there is an overhead in getting the IP packets from the ISP to your modem, which is reflected in the so-called “IP Profile”. The actual throughput of your connection (which is the real speed for the applications that you use) will be lower than the connection speed. The connection speed is the speed at which your router communicates with the DSLAM equipment in the exchange or fibre broadband cabinet. For example, when broadband providers generally talk about broadband speeds (for example, up to 80 Mbps with fibre broadband) they are referring to the connection speed (synch speed). Please bear in mind that speed tests generally report what is known as the throughput of the connection, which is different to (and significantly lower than) the connection speed (otherwise known as the ‘synch speed’). Poor WiFi coverage or interference can often cause rapid fluctuations in speed test results. Try to avoid running an online speed test if connected to your router by WiFi (or a powerline adapter).

Below is our online speed test, provided by Ookla.Īs described in our article Online Speed Tests: how to use them and which are the best, be careful when using online speed tests to judge the speed of your broadband connection. Online speed tests are typically the easiest way to estimate the speed of your broadband connection, but beware inaccurate results.
