I have been doing some work recently to try to resolve poor broadband performance. I though it would be worth recording my experience and the eventual outcome – if you are interested – read on!
In the village where I life it is possible to achieve a broadband speed in the region of about 14 – 17 Mbps download and about 1Mbps upload. The service I was working with was consistently running at .46 Mbps download and about .95 upload. Slower on upload than on download! Something was clearly not right. Also apparently when there was a telephone call active the broadband service would go down. This later issue was easy to fix – there was no ADSL filter on the secondary socket where a wireless phone base station was plugged in!!! Fitting a filter to the secondary socket fixed that problem 😉 But the speed performance remained poor.
I did a reboot of the ADSL router which was an old Netgear one. Same effect. Having been through this sort of situation before I removed the faceplate on the BT main telephone socket and plugged in to the main socket – thus connecting directly to the incoming telephone circuit. I expected that if there might be a problem with the internal telephone wiring that this would over come this and better speed would be possible. This made no difference. I examined the router management system and could see that the basic connection which was being made was 1.5 Mbps download and 1Mbps upload. I understood that this would mean that there was not way that the ADSL speed could be improved.
Diagnosis phase 2 – phone BT Business Broadband helpline
I dialed 151 armed with all the results of my tests so far! The operator went through the standard script that they follow and eventually conducted a line test. First when I was plugged into the line with with the faceplate in place and then with the faceplate removed. This revealed that there was interference on the line which was coming from the internal wiring. This needed to be fixed before things can improve. BT will attend but there will be a charge for the call out……. I wanted to avoid any unnecessary costs!!! The technician did a reset on the line and the speed went much higher when connected with the face plate removed but on replacing the face plate the speed deteriorated. We did notice that with wireless phone connected things were at their worst.
Diagnosis phase 3 – google for help!!!!
Learned a lot – check out these posts http://www.robertos.me.uk/html/ring-bell_wire.html and http://broadband-speedup.blogspot.co.uk/ just a couple many good sources I found! Bottom line is that it is suggested that on internal telephone wiring there are three wires normally connected 2, 5 , and 3 where 2 and 5 are the two blue/white wires (essential for the phone system to operate ) and 3 is the orange wire – 3 is sometimes referred to as the bell or ring wire. The orange wire is historical and would be needed unless you have very old telephone in your house!! Most people do not so this wire is not needed. Also it acts like an Ariel and can introduce noise in to your system which may not be noticeable when making voice calls – but can affect your broadband performance. Solution is to simply remove the orange wire from all sockets in the setup.
I did this and the contract BT to get them to reset the ADSL line again – result is that the broadband is not consistently connecting at much higher speeds with speed tests now demonstrating fairly consistently at around 14Mbps download and 1Mbps upload. This is a good result.
Note – Important of getting BT to do a reset
The line speed reset is a very important part of this process. It seems that when an ADSL service is first installed the exchange will adjust the line speed to achieve the most stable and reliable performance it does this be checking the statistics on the link performance lowering the speed until stable operation is achieved. When it gets to its optimum speed the link parameters are fixed. Interestingly even if the line quality improves the speed will never increase unless BT reset the line again. This reset process takes place over a period of 10 days and cannot be started again during this period. So it is important to get this reset done after all issues/faults on the wiring system have been removed. The above process took about 12 days to complete because of the 10 days needed to complete the line reset.
Interestingly the BT Broadband helpline did not recommend the removal of the bell wire this – their only offer was to send out an engineer at some cost – which I suppose makes some sense from their point of view as this will generate them some revenue 😉
Check this article out which provides details of a new dimension to clothing. The T Shirt featured cans sense if there is a WiFi network in the near vicinity and also indicate what the signal strength of it is.

Also linked into the article is another story about how BT is encouraging its broadband subscribers share their connection with other nearby WiFi users. The methodology sounds pretty feasible with a wireless router configured to have two WiFi network one which is private for the owners use and an open on which can be used by any member of the ‘Fon’ community. I would hope that this means that some one if tracking the use of this open service so that any misuse can be attributed to the visitor not the owner ( should any take place). Also how is the host user compensated for traffic usage if the visitor starts using the host bandwidth to perform large downloads – is this free??? There is scope for further investigation here.

In view of my previous posts about the quality of broadband service in some places in the UK I am not actually convinced that this would actually a very attractive approach. Lets face it if a home user is subscribed to an ADSL service then they are already contending for up stream bandwidth!!! I we know the sort of effect that this can have on the user experience. This could introduce another level of contention on the link up to the DSLAM at the Local Exchange. I don’t think I will be rushing to subscribe. Mind you I suppose this could be a good thing for friendly visitor to the home – but then I can give them access and already do without making my network open to all an sundry!
Further to my last post and in the interests of clarity fairness, see here what Ofcom have to say about UK Broadband as of 26/09/07
Here are the highlights
In general the picture for broadband take-up in the UK is good:
- over ninety-nine per cent of the UK is connected to a broadband enabled exchange;
- over half of UK households have taken up broadband;
- almost three quarters have a choice of at least two broadband (ADSL and/or cable) network providers;
- the average headline speed has doubled in a year to reach 4.6mb/s and
- broadband prices have fallen by 9% in the last twelve months.
Of course I would have to be sceptical about this against the back drop of my own experience.
I need to discover how these statistics were arrived at. Does the term ‘average headline speed’ mean the average of the best performance achievable?????
I was also interested to read the following in the same report
Bandwidth demands are rising
Operators of the current copper-based networks and technologies have already upgraded their technology to deliver faster broadband speeds.
Consumer demand continues for the applications and services supported by these upgrades. To date, the networks have been able to meet this demand and offer sustained improvements.
However, the development and consumption of high speed services means that current generation networks will at some point be unable to deliver the very high speed broadband service that may be demanded by customers.
In the UK operators are considering how best to respond to the continuing growth in demand for bandwidth and the commercial case for significant investment in these new technologies. Ofcom’s consultation highlights how the market and infrastructure conditions in the UK are very different to those countries where investment in fibre has already been strong. The reasons include the relatively mature pay TV market in the UK, the high speeds of current broadband enabled by shorter distances from exchanges and the comparatively high population densities in countries where fibre is advancing fastest.
While the exact nature and timing of demand for very high speed broadband is uncertain, as is the nature of the services that will drive this demand, there is growing agreement that these networks could have profound effects for UK citizens and consumers and the economy.
Seems to confirm my own view that the current generation infrastructure does need to be upgraded to facilitate the delivery of future broadband technology and services.
Thanks to Jack Davidson my colleague at Learning and Teaching Scotland for pointing out the following article which refers to the performance of Broadband Services compared to the rest of Europe.
To read the article click here.
The report to which the article refers is to be found here
The article does state that the average speed of Broadband in Finland is 21.7Mb/s whilst in the United Kingdom the average speed is 2.6Mbps. Also the report states that the average Subscribers per Household in the two are countries are .57 and .50 respectively so it would seem that in penetration terms the two countries are similar. Leaving Europe aside, Korea and Japan actually top the table on 45.6Mbps and 61Mbps with penetration figures of .9 and .52 SpH respectively.
The report by Robert D. Atkinson is actually concerned with “The Case for a National Broadband Policy” in an American context. But it does seems to raise some interesting issues in relation to the real drivers for further investment advanced broadband technologies. At the core of these policies should “focus on stimulating both the supply and the demand for high-speed broadband”. Robert then sets out a number of supply and demand side policies which are both needed to ensure that broadband provision can develop.
I attended a BT technology briefing event recently when I heard about BT’s plans for its 21st Century Network which features the deliver of a wide range of services over the Internet Protocol including voice and video. The interesting thing is that alongside this objective there was no indication of any plan to upgrade the basic network infrastructure over which this will be deliver. Seems to me that before the UK can move up the broadband ladder it needs to get some new policies in place which will stimulate both the Industry and Consumer to exploit the possibilities.
All of this of course is sat against the reality that I still regularly measure broadband download speeds of between 150 and 300 kbps when staying at my daughters house in Bishopbrigs in Glasgow. This is very frustrating performance and seems to be very consistent and is also made more so because of the fact that at 7am each day I can easily and consistently clock 6.5Mbps – clearly this is the effects of network contention.
After reading John Connells comment on my last post I decided to explore the situation in the Netherlands. I very quickly found the following site which provides information about the Citynet Amsterdam project. This project aims to deliver fibre connections to 40,000 homes. read more about it here.
Much of the site is written in Dutch but I could get enough information from it to appreciate this is an approach this has the potential to deliver serious amounts of bandwidth to the home.
I just wonder what the authorities here in the UK cannot see the longterm benefit to move towards this sort of infrastructure. In the UK we always seem to have the infrastructure lagging the needs of the media which are in demand.
I believe that this was true when the first digital services were introduced ( ISDN ) and continues to be the case now when in most cases the best we can get is ADSL – which is ofter heavily contended making performance almost as poor as and analogue modem connection! I have my self collected quite a bit of data that bears this out!
As I write this post a quick check on speedtest.net shows that my current link ( which is an up to 8Mbps service) is providing a 2341 kbps downlink this is actually very good for 8pm when it is not uncommon to experience download speeds of just a few hundred kbps
