Broadband speed checker

A broadband speed test is a useful way to find out if your broadband speed is within your expected range, a slow broadband or a high latency could mean that your internet connection has a fault.

Some broadband providers have their own preferred tool or website for conducting speed tests, below we’ll list the most common.

4. No other devices are connected to your router.

What can cause your speeds to be lower than expected?

Broadband speed can be affected by a huge number of things, the most common causes are:

Cables – If you’re using old or damaged cables then this could be causing your broadband speeds to be slower than they should be.

Time of day – The time of day can be a big factor for broadband speed if you have a contended service. A contended service means at peak times of the day when they’re a lot of users accessing the internet; you may experience slower speeds.

Multiple users – If you’ve got other users in your house using the internet such as downloading or watching movies then it will report a lower speed.

Router placement – If you’re issue is more to do with reliability rather than speed, your issue may be with your router placement instead. Many electrical appliances can cause interference with your broadband which could slow speeds. The material of the walls and the size of your home can also influence speeds, causing your WiFi to be intermittent.
