Slow BB speed

I�ve recently moved home, and I�m not getting the broadband speed of 2 meg I was told I would get by Plusnet and that was shown on the BTw broadband availability checker when I initially moved. I�ve been getting around 1 meg ever since the line became active around 14 days ago. The strange thing is I�ve been regularly checking what speed I should be expecting to get on the BTw broadband availability checker, which originally told me I would be getting 2 meg but this has now change in the last few days to show 1 meg � does anyone know why this would change?

Results from http://www.speedtester.bt.com/
Download speedachieved during the test was - 879 Kbps
For your connection, the acceptable range of speeds is 200-1000 Kbps.
Additional Information:
Your DSL Connection Rate :1280 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 1000 Kbps

Unfortunately Plusnet have told me there is nothing more they can do as I am getting download speed that is within my IP profile which is set at 1000 kbps but I suspect that I should be getting speeds approaching 2 meg. Looking at my router stats I�m getting a down attenuation of 57db which if I plug into the calculator here http://www.kitz.co.uk/adsl/max_speed_calc.php suggests I should be getting an IP profile of 2500kbps. I am right to expect this sort of speed rather than the 1 meg that I am getting?

When I type my postcode in here http://www.kitz.co.uk/adsl/adslchecker.php it shows that my exchange should be Balham which is 1.84km (direct), 3.06km (by road); and I should a DSL Max speed of 1.5Mb. However if I type in my phone number it seems that my phone line is connected to the Wimbledon exchange which is 3.11km (direct) and 4.35km (by road) and DSL Max of 1Mb. So it seems that I�m not connected to the nearest exchange (Balham).

Even more strange when I spoke to Plusnet they told me that my immediate neighbours (I live on a development of 6 houses on a new build development) are connected to the Balham exchange. Any idea why I would be connected to a different exchange to my neighbours?

In addition to this when I moved, my line had a fault, which took 10 days to resolve and I was told that this was because of rewiring works at the Balham exchange. I have a sneaky suspicion that my line was connected to Wimbledon to just get a working line but maybe this has meant that my broadband speed has suffered because the exchange is relatively far away from the property. Is this possible?

Switch the power to your router off and unplug it from the mains, after an hour reconnect the power supply unit and switch the router back on, hopefully the router will sync at a higher rate with the exchange which if high enough will increase the IP profile.

I've tried power cycling the router a number of times, but the sync speed doesn't increase.

Is it a fairly new-build house?

Have you got a master socket where the bottom half of the faceplate comes off after undoing two screws, as in this pic.

If so, see what stats you get using the test socket on the wall at the back. Do not use a plug-in extension cable to reach it though, just router >> short ADSL cable >> filter >> test socket.

You had the same thought as me!

In reference to community.plus.net/forum/index.php/topic,88610.msg736938.html#msg73...:

Given your attenuation your sync speed seems a bit low.

Have you tried connecting the router to the test socket inside the master socket to compare the router stats?

You obviously didn't read the reply under your post.

I haven't got a split master socket with a test plug, so I can't test using that.
