he seems to be in that shop alot outside of working hours.

He certainly does,particularly after he shuts shop for the day he typically will be in the shop going through paperwork(seeing how much profit he can/has made)Ka-ching ,with all or most of the lights on including some in the windows needlessly burning away some of that precious profit and more importantly stopping me using my adsl connection,lol
He may be due to go an his holidays soon (if he ain't too tight fisted) maybe then i'll get the opportunity to see how the internal telephone extensions are routed as one or two of the workers seem chatty enough,And if i was able to identify a problem and the cable could not be simply re-routed in a not so obvious way, then i could substitute the cable with a shielded type ,lol, that's assuming things are straight forward enough,

no updates?

here I still have interference however I am now syncing low and putting up with it.

Interesting to note my upload is defenitly also affected, not by a huge amount but its down by about 50kbit and is a consistent loss.

Not anything to update, still more or less the same,except the downstream SNR seems to be affected in that it will decrease by 1db sometimes a bit more at the times the interference is present, last night well just after 12 my connection went down for around 15 mins, dunno why, and i lost around 100kbits on my d/load sync,i'm sure i'll get it back though eventually,lol packet loss today has been less than it was yesterday, but still has the adverse effect on throughput the upload speed seems to be affected on speedtest results, but if i use an ftp or the rs upload tool it still seems to max it out,except on the rare occasion of 50%+ packet loss
I'm waiting for the shop owner to go off on his holidays, then i can get a proper look at the wiring setup(internal phone extensions) i have been told that the master socket is positioned next to the mains supply fuse box or meter , and that the shop wiring is a mess never seen an electrician for years,though how true this is i don't know, but the bt master socket surely should never be positioned near the incoming mains electric supply,???

Today there have been some development's in that ii had several losses of sync or ppp sessions, after each,the d/s sync reduced so at the minute i have lost nearly 1 mbit the other changes are that the d/s seems to be a static 4db and the u/s snr appears to of been lowered by 1db so i see 5db instead of 6db (but should be 4db)
but on the plus side of things the packet loss and the high error rate seem to be gone, so throughput also not as fast as before, is back to normal, but however it could be just some co-incidence ,only time will tell,
But i do re call a brief period after my line fault was fixed it was a tuesday ,i suffered next to no problems for the rest of that week, but the following Monday i did ? so i'm not convinced as yet that this is fixed

Interesting thing on my line I just noticed and probably explains the weaker upload sync, the attenuation has gone up by about 5db, this is consistent.

attenuation is supposed to be a static value with maybe very small variances between syncs, a 5db move as I understand it should not happen unless something physically changes.

An HR fault could conceivably cause attenuation to vary.

talking of attenuation the d/s on my connection has decreased by 0.5db yesterday following the number of re-syncs, but i know the netgear reports a higher value, as the real attenuation is 28db, i only know this cause i asked dan,

I may of found a way of avoiding this noise/interference during the opening times of the shop, that is wait until it causes the downstream snr to decrease below the set target of 4db, then re boot the router, it syncs at a slightly lower rate, then to re gain the higher rate repeat once the snr rises once the interference stops, so it is similar to adjusting the snr values , worked today, well nearly, still around 200kbps shy of the highest sync achieved, the only thing that i am annoyed about is the loss of ppp i have been getting recently it dropped early this morning as i was playing a game on line, i think uko had some probs as later the web page and e-mail server were down, for a while

I have suspected HR for months, even years. But cant get it investigated.

openreach/BTw is now of the mindset that everyone's equipment or wiring is too blame and have got too greedy on callouts which has scared most isp's off.

looking at my graphs the attenuation increased march april time. It has always jumped around but before was around 49-52db range and is now 54-57 range.

the ppp thing is a netgear problem.
