On this page you will be able to check to see what speed your getting from your current connection and see if your getting the an acceptable amount for your line. there are 3 methods we use to check the performance of our connections and these are speed tests, latency tests and checking the sync rate (connection speed) in the router.

You will need your Sync Rate (Connection Speed/Rate) for Downstream/Upstream , the SNR Margin (Noise Margin) and the Line Attenuation.

Typical connection stats would look something like this:

ADSL Link Downstream Upstream
Connection Speed 16612 kbps 1295 kbps
Line Attenuation 27.0 db 13.7 db
Noise Margin 6.0 db 6.1 db

Connection Speed: This is the connection rate that your router is connected to the telephone exchange at, with overheads the actual speed you get will be slightly less.
Line Attenuation: This figure represents the quality and length of your line, the larger the number; the longer and/or worse quality the line is which result in lower connection speeds.
Noise Margin (SNR Margin): This figure represents the Signal-to-Noise Ratio Margin that is set to help keep a stable line and prevent dropouts (disconnections).

For more info about how it all works see the 'How Does It All Work?' page.

Once you have the figures above the first thing you need to do is check against the chart below to see if your getting a lower than average Connection Speed (Sync Rate) which would indicate a problem on the line, usual suspect is interfence (REIN) and bad wiring - if at this stage you have determined your speed is low and you do have a problem then visit the Speed Up Your Internet page to try and rectify, otherwise continue below.

The Chart above shows the average Connection Speed and Line Attenuation Figure over distance, you should match up your Line Attenuation to the speed on the chart to see what you should be getting, you should also use the color code to match to your connection type, if your on an 'upto 8Mb' package or less then your on ADSL (blue), if your on an 'upto 20Mb' (or 'upto 24Mb') package then your on ADSL2/ADSL2+ (green), if your not sure you can ask your provider. As you can see from the example above that the connection speed is about right, it doesnt have to be 'dot on' as these are just 'averages' as long as its within reasonable range, say if the connection speed in example above was 12,000Kbps or below then I would expect that something wasnt right and would look into it, you also have to bare in mind that someone lving relatively close to the exchange could have poor quality line with aluminium on it somewhere and/or bad rusty connectors making a potentially great line poor and thus giving someone who lives close to the exchange a higher Line Attenuation figure, there is little you can do about these situations unless it affects your telephone calls, or, your broadband is just about completely useless, it may be possible to get your route to the exchange changed (by changing the D-side and E-side cabling) to try and avoid bad wiring and gain some speed but it can be quite hard to get this done.

If your not getting what you expected then head over to the Speed Up Your Internet page to try and rectify, if everything looks OK on your Router Stats and your getting about the right speed then this indicates that the connection itself appears fine, what you need to check for now is the actual speed over the network, just because your router is 'synced' at said speed does not mean you will be getting that speed, you always get slightly less than the connection speed anyway due to overheads but then there is network traffic and other issues that can cause slow downs on your Broadband connection.

***Before you run these tests be sure nobody else is using your network or broadband and that you have no applications running on your computer that may be downloading files in the background or using the internet in anyway, its essential that when testing your connection there should be no activity on the line***

What we do now is test the line itself to see how it performs, we do this by running speedtests and latency tests, first of all make sure you are connected to your router by Ethernet LAN cable and not using Wi-Fi as this can affect results, also make sure no-one else is using Internet on your network (for e.g. from another laptop, PC, Xbox, PS3 or Mobile Phone etc in another room) and make sure their are no applications using internet on your laptop/PC (like torrent programs downloading files in background). You can use our speedtester to determine what your throughput is, the best thing to do of course is use at least two or three different testing sites to make sure the readings you are getting are accurate as speedtest websites may give varying results depending on their current load and distance from you to their testing servers, Speedtest websites that are reliable include speedtest.net , BBmax and of course our own speedtester. Your download throughput should be slightly less than your connection speed, how much less depends on type of connection and the acutal speed of it but its usually about 10% but can be anywhere from as little as 2-3% to as much as 15-20% depending on the type of connection itself, length of line and any SNR tweaking that may be going on, a proper download test result (for e.g.) on a line with 5,000k downstream rate would be something like 4.5Mbps (4,500k) or there-abouts.

If you test your line with the speedtesters and they report what you should be expecting then we will commence to the latency tests, but if they are not then visit the Speed Up Your Internet page to try and find out why and how to sort it out.
