Estimated cable length certainly no more than 0.6 of a mile ... BUT accross a motorway and with old cable. I am told it need replacing but as it serves only 4 houses the chances are slim.

old or not if it passes the quality benchmark it will be perfect..its usually the joints that cuase issues not the cable itself

In reply to a post by Thermal:
HI RobertoS.

Data requested is

ADSL line status
Connection information
Line state Connected
Connection time 2 days, 22:43:48
Downstream 544 Kbps
Upstream 448 Kbps

And comes as a shock to me as it is much better than I thought. BUT ... why is it so different from the Thinkbroadband speed test. ?

Unfortunately you have selected what you think I need to know. Basic stats include the attenuation and noise margin in both directions, and fuller stats include a host of error stats and other details.

If you can include those it is possible to get some idea of the state of your line. All we know so far is that it connects at a low speed. From the full stats we can see what speed is to be expected, which may be the same or it may be much higher.

As to why the connection speed and the tbb speed test are so much different, the speed reported by tbb is good for the connection speed. BT Wholesale has an IP Profile system, and if you look at the table on that page you will see your top throughput speed has to be below 350kbps.

They aren't really taking that big a chunk out of you though. On ADSLx there are overheads of 13%-18% from the packaging of the data, and a large part of those overheads is accounted for in the difference between the connection speed and the IP Profile.

means you're a long way from any where.

Sorry thermal, this one slipped through my radar today.

As orly says, you are a long way from the exchange as you already know. The attenuation figures show that, but it's also a sad fact that the true attenuation is almost certainly much higher as those are the highest numbers many routers can display.

There is a possibility that you connection speed could be improved in two ways.

First you seem to have connected at night which always results in a lower connection speed than if you connect during daylight. Try reconnecting fairly close to mid-day at this time of year, but don't do more than two or three tries in an hour. The probable trigger point for the BT system to think your line is unstable is 10 in an hour, but given where you are starting from we don't want to go anywhere near that, in case something else on your line makes it more sensitive. The system could slow you down even more if this happens.

If you connect at 576kbps which is only a fraction more than now, then a few days later your BT IP Profile will rise to 500kbps, and you will get a bit more actual speed as a result. If you strike really lucky and get 864kbps or more (it goes in 32kbps steps) your profile would become 750kbps, more than double what you have now.

The second way is to make sure your connections and phone wiring are optimised. Do you have a split-face master socket where the bottom half will come off after undoing two screws? If so, is your router connected to it using just a short ADSL cable and a filter?

If not, please can you describe what you have connected to the phone where smile.

Thanks to both Orly and RobertoS and very interesting.

I would agree that I am some way from the exchange ... about 6/7 kilometers away to be precise ... but only circa 600 meters from the cabinet but that would affect "Infinity" only.

I was so keen to get the best result I could that I have had a new dedicated line installed with split face master socket and the router is the only thing connected to it ... so I doubt if that can be improved.

I am very intrigued about "resetting" the router at the best time as I used to get 864 when I first started. I had no idea that I could "encourage" BT to increase my profile. This I will try and report back.

Thanks again for all your help.
