Fast.com

Speedtest by Ookla

It might sound like some kind of Jazz Funk album from the seventies, but Speedtest by Ookla is another excellent way to gauge the performance of your network. When you visit the site, you’re greeted with a large button marked Go, so it’s hardly a complicated user experience.

As the test runs you’ll see a graphic akin to a speedometer in a car, the needle of which will hopefully remain high. Once the download speed is calculated it moves onto upload speeds while also letting you know the Ping rate, which is an essential factor for online gaming.

Should you prefer, Ookla offers free apps for Android, iOS, Windows, macOS and others so you can launch a test straight from your desktop or home screen.

Speedof.me

One tester that takes a more modern approach is Speedof.me, which uses HTML 5 rather than the normal Flash or Java to conduct its analysis. This can make the process a little bit quicker but is probably more appealing for those who want to use their mobile devices to measure the network performance. Most smartphones and tablets don’t run Flash anymore, so Speedof.me offers a great alternative.

The interface is easy to understand, with a large wave graphic indicating the speed and consistency of the signal, but of course there are numbers given so you can make sense of it all.

ISP tests

As well as the independent services listed above, you will also find that your ISP (Internet Service Provider) will also have a speed test available online. This can a useful way of showing them that your connection is not running as efficiently as it should, but we’d also recommend running all of the ones above before you go to the ISP as it will give you additional results to use in your discussion.

You’ll usually find the feature by Googling the name of your provider and speed test together or visiting its website and doing a search there. There’s a good chance you may need to log into your account before accessing the test, so be sure to have your details to hand.

In the UK, there are tests available from BT, Virgin, Talk Talk, Sky and others, while most US and European services also offer the feature.
