But, it's important to make the most of it!
Your broadband speed determines how fast you can download and upload data. If your internet feels slow, it could be due to a variety of factors. This can include network congestion, outdated equipment, or even an issue with your ISP. Testing your speed can help you diagnose the issue and optimise your connection. Here's how:
Choose the right device Start with a modern device that supports high speeds. Older laptops, phones, or TVs may have speed caps, so double-check your device's specifications if results seem low.
Get connected For the most reliable results, use a CAT6 Ethernet Cable to connect your device directly into the router, clise any unnecessary apps or programs running on the device, and disable any VPNs (especially on work devices), as they can interfere with speed test results.
Disconnect other devices To avoid other devices using bandwidth during the test, temporarily disconnect all other devices from the network and ensure no one else is online at the time.
Run the test multiple times Run your speed test at various times of the day to get an accurate understanding of your connection's performance during peak and off-peak hours.
Troubleshooting tips
If your results are lower than expected, verify your device supports high-speed connections, check your Ethernet cable and router set-up, and ensure no other devices are using the bandwidth. Still seeing issues? Get in touch with our Tech Support team for expert help.

Where can I run a speed test
It’s important to choose a reliable speed test tool. There’s several out there, including:
Each of these tools measures your download speed, upload speed, and ping. Still seeing issues? Contact our support team for expert help.

How does wi-fi reach every room?
Your router pushes out radio waves, transmitting millions of bits of data per second, to your devices – like smart phones, computers or tablets.
It’s through these airwaves and technology that you are able to stream your favourite shows, battle your opponents online and work from home. But, there are some interfering elements that could make your connection slow and ruin your downtime, keep reading below to see what they are.

Why does my wi-fi feel slower in some rooms?
Walls, floors, and large objects can block signals. Have you considered using a wi-fi extender for better coverage? Find out more.

What household items are causing interference?
There’s a number of unexpected things that could be slowing down your wi-fi signal, as they have the ability to absorb or reflect wireless signals.
- Mirrors. They don’t just reflect light. Mirrors with even a thin metal backing can reflect wi-fi signals, causing them to bounce around and potentially create dead zones or electromagnetic interference.
- Bluetooth devices. Bluetooth devices, such as speakers, keyboards, and headphones, can operate on similar frequencies as wi-fi and might cause interference if they’re in close proximity. Our recommendation? If you’re not using it, switch it off!
- Fluorescent lights. Believe it or not, certain types of fluorescent lights can emit electromagnetic interference that can impact your connection, especially in the 2.4 GHz range. If possible, give alternative lights a go – like LED.
- Water. It’s bad news for your family goldfish. Water can absorb and weaken wi-fi signals. Large containers of water like fish tanks, or even a crowded room of people, can reduce performance.
- Microwaves. They’re a recipe for disaster! That’s right, microwaves also operate in the 2.4 GHz frequency range and can cause temporary interference when in use.
- Corded electronics. Some corded electronics, especially those with motors or transformers, can generate electromagnetic interference that might impact wi-fi performance.
- Walls and floors. As you would have guessed, thick walls made of concrete or brick, as well as floors with metal reinforcement, can significantly weaken wi-fi signals as they absorb or reflect the wireless signals.

How do I know I'm on the right frequency?
One travels further, and the other faster. Make sure your devices are on the right frequency for their needs. Our service transmits both 2.4GHz (further at lower speeds) and 5GHz (closer range but faster speeds).
Each device might have a preferred frequency, and you can check on the settings. We recommend putting your laptops, tablets and mobiles on 5GHz.
