Plain English answers to your broadband questions.
You'll need a broadband modem (around £40 for a standard modem). Some ISPs provide this for free in exchange to signing up to a 12 month contract.
Most ISPs provide a free installation disc and 1 or 2 microfilters – small devices that plug into your phone points to let you receive calls and access the net at the same time. You can buy extra microfilters from around £4.
Once you've run the installation disc, just plug the modem into your computer's USB port and into the phone socket via a microfilter. Don't be put off if this sounds daunting – most members we've asked find broadband easy to install.
Installing cable broadband might require an engineer's visit but, if you already have cable TV, you can install broadband simply by linking your computer to your set-top box.
Broadband can be anything from 10 to 150 times faster than a dial-up internet connection. ISPs quote maximum download speeds: your service may be slower at busy times.
Data transfer speed is measured in Kbps (kilobits per second – one kilobit is 1,000 bits) and Mbps (megabits per second – a megabit is 1,000,000 bits).
The actual speed you will receive depends on a number of factors, such as how far your phone line has to stretch from the nearest telephone exchange, the quality of the line, and the contention ratio of the service (see below), so you may not always, or even ever, get the advertised speed, particularly for services advertised as up to 8Mbps or higher.
If you have a non-cable phone line, go to the Broadband ASDL Availability Checker and enter your phone number – it will give you a provisional guide on what broadband speeds your phone line should be able to support based on where you live.
To find out more about how to get the right internet connection speed have a look at our broadband speed report.

Onspeed costs £24.99 a year claims to increase dial-up and broadband (up to 2Mbps) speeds by compressing web pages and emails so they load faster.
Most home users download more than they upload, so it’s more important for download speeds to be faster, and this is the speed ISPs usually advertise.
The fastest upload speed we’ve seen is 1.3Mbps from high-speed broadband provider Be, but can be as low as 256Kbps, so check upload speeds in advance if you think you’ll find slow speeds restrictive.
With some broadband services, you're connected to the internet as soon as you turn on your computer. Others require you to log on. Either way, it's much quicker than dialling up.
Unlike dial-up packages, broadband services don't limit the time you spend online. Instead, most broadband ISPs charge a monthly fee and let you download or upload a certain amount of data.
Some providers offer unlimited use. These are usually subject to fair usage policies but are only likely to be restrictive to very heavy broadband users.
We provide details on more than 150 packages from around 30 broadband ISPs that we have customer satisfaction ratings for, plus a selection of other providers that offer services we think you should be aware of in order to make an informed decision.
Other packages may be similar in terms of price and features, but we have no evidence on what the service is like in practice.
Most contracts allow ISPs to increase prices by a certain amount, although there's often a clause to say they have to let you know in advance and allow you to break the contract if the increase is significant.
In the first instance you should go through the company’s internal complaints procedure.
If that fails, after 12 weeks from the date of the original complaint (verbal or written), you can take the matter to the telecommunications ombudsman (Otelo), the Communications & Internet Services Adjudication Scheme (Cisas) or the Internet Service Providers Association (ISPA), if your ISP is a member.
Keep records of all written and verbal communication.
You may be able to get broadband via cable, if you live in an area that has it – check if your area has cable.
Alternatively, you could consider mobile or satellite broadband. See 'Features explained' for more.
The contention ratio is the maximum number of people an ISP will allow to share a connection at the same time. The higher the contention ratio, the more people could be connected – and the slower your download speeds.
Residential services are most commonly capped at 50:1, which means you'll never share a connection with more than 49 other people.
One of the biggest risks of being online comes from files you download, which could contain computer viruses, but hackers are also finding increasingly innovative ways of getting access to your system.
So it's really important you protect yourself from these threats by installing anti-virus and firewall software on your computer and updating it regularly.
You should also look for an ISP that offers security features, such as spam filters.
If you want to switch ISP but aren’t quite sure where to start, take a look at our guide to switching ISP which explains how to change broadband provider or how to upgrade from dial-up to broadband.
