We'd also recommend using another speed test such as this Broadband Speed Test to compare your results, and testing at several different times of the day and night to see how peaktime network congestion affects your service. We recommend running the test more than once to make sure there wasn't some sort of blip during your first test. Some Internet connected audio-video equipment or services designed to allow access to video content in other countries can also have an affect on our test results. Our test uses the HTTP protocol over TCP port 80, if you're having trouble with the test make sure that this traffic isn't handled by a proxy or blocked by a firewall. This can artificially increase your test speed or even prevent the test from completing. If possible, avoid using proxies, VPNs, and 'Turbo' features, some browsers or broadband providers offer features designed to speed up your connection by processing the data that goes through your connection before you receive it. If you're on a mobile device or have to use wireless, try to stay relatively close to your router, preferably within line of site, and avoid running equipment that can cause interference such as microwave ovens or unshielded flashing lights. Wireless networks can get slower the further away from the router you are and can suffer interference from thick walls or metal objects. If possible, connect by cable rather than wirelessly. If possible turn these off or turn off the wifi connection.
#SPEEDTEST BY OOKLA EXTENSION TV#
Make sure that no other devices are using your network, this could include a TV box or games console in the living room or the smartphone in your pocket. This is especially important if you have a slow computer or you're running the test on a tablet or mobile phone and tend to wait a long time for apps to load.
#SPEEDTEST BY OOKLA EXTENSION WINDOWS#
If possible close all other apps, browser windows and tabs and try to run the speed test alone. If your virus checker is in the middle of a scan or you're busy copying files or converting a video, this is likely to slow down your computer and so affect how accurately the speed test can run. Make sure that nothing intensive is running on your computer. It can also include online radio, background downloads and updates to your virus checker or operating system. This includes other apps on your computer like your email client, instant messenger or browser tabs running Facebook or other constantly updating sites. Make sure that nothing else is using your Internet connection. Some providers "throttle" their networks at peak times which can cause broadband connections to slow, but testing your connection regularly you can find out if your supplier is doing this to you.Īs well as testing your broadband speed, we'll also let you know how your speeds compare to those of other broadband customers and let you know if there are faster providers in your area. Without broadband speed test tools there would be no way of holding your supplier to account, you just wouldn't know if you were getting the service you are paying for. Your test results will help us compile our monthly speed test results which show the fastest and slowest broadband providers in the UK.


These are recorded by a different method involving equipment installed in the home to record speeds during day-to-day usage. Ofcom have also published average broadband speeds recorded across the UK, including individual figures for the largest providers, different types of broadband and different types of neighbourhood.

Mobile broadband providers and those that only serve business customers are not counted towards the national average figure. Broadband provider is detected by IP address rather than self selection.

We record hundreds of thousands of test results every month.
