That's a pretty poor sync speed, even for the relatively high attenuation figure of 59dB.

Has house wiring been eliminated as an issue? The easiest way to test that is, assuming it's a standard master socket, is to use the test socket. Unscrew the faceplate (which should disconnect any extensions) and then plug the modem into the test socket underneath. Then check the sync stats. (This is assuming all the wiring has been done properly).

Note that don't worry if you have to use a temporary set-up with an extension lead to power the modem/router. It's just to baseline the performance.

Of course if there are no extensions, then this won't be necessary. But if their are any (including unused ones), then it will almost certainly degrade performance. If it does, there are some fixes (at least one of which is simple and free).

DY4 7LU is not a current postcode

http://labs.thinkbroadband.com/local/?postcode=DY4%2... shows what we know is available on the exchange and for specific postcodes

It also has a lot of the altnet providers on it

DY4 7DB

My daughter's postcode is DY4 9FD. Yes, the first thing I did was to unplug the faceplate and plug straight in, un power the DECT cordless phone in case of RFI, re-start the router etc. I did the BT test and it came up at around 1.5Meg to 2 Meg max which is pretty bad, although better than now! I did the tests Friday, I'm back home now so don't have access to the line at present (I live in Hampshire!). This has been ongoing for some time, and Sky identified the DLM set to 300k previously, cleared this, speed went up to around 2 Meg for a few days then back down again!

Sorry, I edited my post and for some reason it posted both the incorrect original and the corrected version. Only just noticed. The correct post is the DY4 9FD one, please ignore the other one!

Even stranger, the edited version shows an earlier time stamp?

An update on this one. After a promise for BT Openreach to attend in the mean time, they failed to turn up. The download speed reduced again to 90K.

The visit was re-scheduled again for today. This time the engineer arrived, and followed the pair back to the distribution panel, and then right back to the Tipton exchange. He found that one wire was loose and intermittent at the exchange end, and tightened it up. The speed has gone up to around 2 Meg straight away, he said that due to the line length it is unlikely to be much better than that. My daughter is sticking with Sky for the moment, and asked them to monitor the line stats for a while. Many thanks for all the comments.

Once it settles it might be worth checking the Ring wire.

best isp depends on requirements, there is sadly no such thing as a perfect isp.

so

to deal with BT regarding faults. - AAISP
for cheap prices - one of those providers who doesnt specialise in broadband and as such usually sells it dirt cheap.
for performance - imo, sky in a LLU area, however people will have different opinions. Talktalk business based isp's seem rated highly as well for performance. (not to be confused with talktalk retail).
for best supplied hardware - maybe BT or virgin media.
for best access speed (not to be confused with throughput) - virgin media
