Now you know more about broadband in Cardiff you can check if your connection is up to scratch by running a speed test.
Use our fast and accurate speed test to check what speeds you're getting in Cardiff.
It's possible the speed test will display results which differ from the advertised speed of your broadband package.
Many factors come into play when looking at speed test readings including: peak time usage, provider issues, router issues, computer viruses and property location.
Broadband providers are obliged to advertise their average speeds which at least 50% of their customers receive. Unfortunately, if you're receiving speeds below the advertised, it's likely that your property is only capable of receiving below average speeds.
What is a good speed for broadband?
Faster broadband speed can play a huge role in our day to day life. It's important to have an understanding of what the speeds you see advertised by broadband providers for Cardiff convert to in the real world.
Generally, the more people using the internet, the slower your connection will become. However, this isn't a hard and fast rule and does depend on how many devices are connected to the internet at any one time. Let's compare broadband speeds:
This speed will suffice for smaller households with few devices simultaneously connected. Occasional buffering may occur during streaming.
This is the ideal speed for a standard household. It can cope with multiple people streaming or downloading at any given time. This bracket is likely to offer affordable prices and a suitably fast connection.
This final speed bracket is worth considering for households looking for lag-free connections for several devices. 50-100Mbps is a brilliant broadband option for streaming 4K and shouldn't encounter any connection issues when gaming online.
Broadband above 100Mbps will provide fast speeds for any household and cope easily with streaming and gaming. Speeds above 300Mbps are classified as Ultrafast connections. Ultrafast broadband is not necessary for the majority of UK households however, the incredibly fast speeds can prove tempting for those who rely heavily on their broadband speeds. Gigabit (1000Mbps) connections are also now becoming increasingly common across the UK with speeds above 1Gbps. These types of speeds eclipse older broadband technology.
But how fast is 100Mbps broadband?

Everything else you might need to know
Now you've got all the information you could ever need to know about broadband in Cardiff, we've compiled some helpful information to help you understand your Cardiff based broadband better.
A popular form of broadband that uses your pre-existing phone line. Nothing more than a phone line is needed to install an ADSL connection. This type of connection is practical and common in the UK however rural homes might face limitations. ADSL broadband is the least expensive option but this will likely be reflected in connection speed.
Fibre (FTTC or FTTP)
Fibre optic connections are designed to be incredibly fast and stable. This is often the preferred choice for busy homes with several connected devices that require fibre speeds. Like ADSL, fibre optic connections are accessible across the country however rural households may experience issues. The two kinds of fibre broadband plans are called fibre to the cabinet (FTTC) and fibre to the premises (FTTP).
Just as it sounds - unlimited broadband connections have no cap on the amount of data you can use.
An unlimited broadband package ensures that you can never use too much data but will cost more as a consequence.
While fibre broadband is offered by numerous ISPs to supply superfast and ultrafast broadband speeds, cable broadband is something specific to certain providers such as Virgin Media broadband who function on their own network.
Frequently picked as an alternative to ADSL or cable for rural properties. Unsurprisingly, you'll require a physical satellite dish set up in order to have a satellite broadband connection. The cost of satellite internet tends to be more than fixed line broadband.
Advertised vs Real Speeds
The way in which broadband speeds are advertised changed drastically in May 2018. Thanks to the Advertising Standards Authority, broadband providers must now market their 'average' speed rather than their 'up to' speed.
In simpler terms, your speed is now more likely to match or maybe exceed the marketed broadband speed than it was a couple of years ago. In order to be described as 'average', more than 50% of users should get these speeds in between peak usage hours (8 pm to 10 pm).
Broadband providers can also still market their top speeds in addition to their average speeds. However, keep in mind that these speeds are unlikely to match the speed you would receive if you sign up for that specific package or provider. Top speeds are just available to a select few.
There is no guarantee that you will get the marketed average speed so it is well worth checking what the minimum speed provisions are.
If, for whatever reason, your speeds do not stack up to this minimum speed, you might be eligible for money back or a free cancellation. Make sure to read through contracts with care. This will give you the best indication of what your broadband speed is most likely to be and will provide details on your minimum expectations.
The world of broadband can be confusing at times so we've created a handy glossary of commonly used terms that you might come across when looking for a broadband package.

The capacity of a broadband connection. Things that use a lot of bandwidth are using a lot of your broadband data transfer capacity. This, in turn, can slow down other activities that need the use of your broadband connection.
Byte, KB, MB, GB
A byte is a unit of data. KB means 'kilobyte' which is equivalent to 1000 bytes. MB stands for 'megabyte' which is equal to 1000 KB. GB means 'gigabyte' which is equal to 1000 MB.
A high-speed internet connection. What makes it 'high-speed' varies from country to country.
A cap imposed by a broadband provider. Used to either refer to a data limit or when discussing throttling. Exceeding your cap can lead to additional charges.
An internet connection that utilises a modem. Primarily only used outside the UK as broadband has made this technology dated. Connection speeds are substantially slower with dial-up internet.
The speed at which your internet connection is able to receive data. This figure is greatly showcased by internet service providers on their broadband deals. This speed will be shown in one of three ways - kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).
A wired connection supported by home broadband routers. Ethernet cables are usually yellow and are believed to be more reliable than a Wi-Fi connection. They have fast connection speeds and are usually the connection of choice for online gamers.
Fair use policy. A data cap put in place by the broadband provider. Not all packages will have one and those that do need to make their limits clear thanks to Advertising Standards Authority regulations.
Fibre Optic Broadband
A data transferal approach utilising pulses of light transmitted throughout plastic/glass cables. Ultrafast fibre broadband is gradually becoming the dominant type of connection in the UK as outdated copper wiring is changed out. Fibre optic broadband speeds differ depending on kind of connection with fibre to the cabinet (FTTC) being slower than fibre to the premises (FTTP).
A means of distributing files such as images, music, videos, and software. Can be conducted peer-to-peer (P2P) or via a network. In some cases connected with piracy but not fundamentally illegitimate.
Fixed Line Broadband
Internet provided through a physical link like fibre optic cables or ADSL. Often used to distinguish between fixed line broadband and wireless mobile broadband or satellite internet.

Local area network. A network that covers a small area like a house or building. LANs tend to use network cables or Wi-Fi.
A telephone line that comes into your property. Typically required to get broadband however alternatives such as mobile broadband and satellite internet are sometimes available.
