What to do before you run your speed test
There are a few things you can do before you start the speed test to get more accurate results, for example, cancelling downloads and running the test at different times of the day.
Our guide What broadband speed do you need? covers the full checklist and offers ways to improve your broadband speed.
What do my results mean?
Your speed test results show how fast you can download or upload content on the device you’re testing and how much of a delay there is.
Many factors affect recorded speeds, including:
- time of day
- device type
- location
- your browser
What is a good speed?
Check your results against the advertised speed of your broadband service. A good speed is one that closely resembles what your provider has advertised.
Bear in mind that “Speed (average)” shows the speed available to at least 50% of customers. “Speed (absolute)” shows the speed available to customers for the advertised plan.
Where a provider has not given an “average speed or absolute” speed, the maximum possible speed for the advertised plan is usually shown as “Up to”. Few people get this speed, which is a maximum, not a guarantee.
What does Mbps stand for?
Mbps stands for megabits per seconds and one megabit is equal to one million bits of information.
What does Jitter mean?
This is the variation in ping or latency, and it’s an average of the lowest and highest response times in milliseconds. It’s also known as Packet Delay Variation (PDV).
Ideally, the jitter should be below 30ms as higher readings are likely to result in buffering and lagging.
What does Ping mean?
Ping is like latency and measures the time (in milliseconds) it takes for your device to respond after you’ve sent a request.
The higher the ping, the more lagging or buffering you’ll experience. If you’re into gaming, this is particularly frustrating but even for general browsing, pages will take a long time to load.
As a guide, a ping below 50ms is good and above 150ms will result in lagging.
Stuck with a slow speeds?
If you’re still struggling with a slow connection after ruling out the possible causes in our guide How to speed up slow broadband, you could switch to a new provider.
Our guide to switching broadband providers walks you through the process step by step and can help answer many of your queries.
