With this broadband speed booster guide, you’ll discover how to improve broadband speed to get the very fastest speeds that your line is capable of. Below are ten top tips. A page is provided for each tip, so you can choose to read them all (recommended) or just go to the ones you are particularly interested in.

TIP 1: Determine your actual connection speedtip1
Before you start, you need to know what speed you are achieving and online speed tests can be very inaccurate. You can find this information by connecting to your modem via your browser.

Go for superfast broadbandTIP 2: Opt for a fibre broadband service. To maximise speeds, opt for a fibre broadband service (sometimes referred to as ‘superfast broadband’) if available. The availability of fibre broadband is increasing rapidly, although this may not be widely advertised in your area, and prices may be lower than you think.

ADSL2+TIP 3: Opt for ADSL2+ over basic ADSL. In the absence of fibre broadband, opt for an ADSL2+ service if available to you, since ADSL2+ offers superior download and upload speeds compared with basic ADSL. Note that ADSL2+ will not necessarily be automatically provided even if available from your exchange.

tip4TIP 4: Ensure you have an NTE5 BT master socket installed. Many properties, particularly older ones, may not have a proper BT master socket installed, limiting your options to improve broadband speed since you cannot fit a faceplate (described in Tip 5, below). We recommend having one fitted.

Fit a faceplateTIP 5: Fit a filtered faceplate. A filtered faceplate (costing less than £10) can substantially increase broadband speeds, particularly if you have telephone extension sockets in your home. The filters faceplate fits on the NTE5, and ensures that your broadband signal is not carried around your house.

Don't use long extension cablesTIP 6: Connect your modem to the master socket. It is very important that you avoid using long extension cables between the master socket and your modem, and don’t connect your modem to an extension socket. For best performance, connect your modem to the master socket with a short modem cable.

Adjust target SNR marginTIP 7: Optimise the target SNR margin. Ensure the optimum target SNR margin is used on your line, tweaking (if necessary) the target SNR margin if your modem supports this. Only a small number of modems support this feature. Reducing the target SNR margin can substantially increase download speeds.

Use EthernetTIP 8: Optimise WiFi, connecting by Ethernet where possible. WiFi can often be the weak link in your broadband chain, and it needs careful set-up to avoid interference and range issues. Ethernet is always the best way to connect devices (for example, set-top boxes and desktop PCs) that don’t move.

Billion modemTIP 9: Consider replacing your existing modem router. Your broadband connection may be limited by the performance of your current modem router, particularly on challenging lines, and the best modem routers support enhancements such as SNR adjustment, G.INP and multicast.

Multiple connectionsTIP 10: Consider a second line. If you have squeezed out the maximum possible performance from your broadband connection, consider getting a second line. Multiple lines can be bonded together to improve speeds. So, two slow 3 Mbps lines can be converted into a quicker 6 Mbps connection, for example.


Following all these tips will ensure you achieve the very best speeds from your broadband connection.
