I live in a rural location, in a wireless blind-spot, roughly 5km from my exchange at Flamborough, and the line attenuation is 67.7 and noise margin is usually 15.0. Since moving to Plusnet from BT (when the line rate varied from 95kbps to 1000kbps), they have very helpfully steered me to a line rate of around 1300kbps, by interleaving, and by prompting me to upgrade the internal phone wiring. Just recently, the line rate has dropped to 800kbps (even at the engineers socket), and that is being pursued via a ticket.
I've tried 4 types of ADSL modems (BT Home Hub, 2700HGV, ST585, Voyager 210), and have had the best results with a BT 2700HGV, but am prepared to invest in a better-performing modem/kit etc if such can be identified. I've also found that microfilters all produce different results, usually marginally and usually reflected most obviously in the CRC rate.
Has anyone out there had similar issues and is able to give me advice to help get the most from my ADSl line?
Thanks in anticipation.

ADSLNation filters are held in high regard, either the XF-1e rat's tail type, or, preferably, the XTE-2005 filtered faceplate fitted to the master socket. The latter also has terminals providing an unfiltered outlet for wiring a dedicated ADSL extension (preferably with Cat5e cable).

I've taken up the suggestion re the XF-1E filters, and have ordered a couple today. I wouldn't go the faceplate way because the main socket is in an 'unusable/impractical' site in the kitchen, and I have a fixed cat5 cable extension (no ring wire) to 9m away where a rat's-tail microfilter then feeds phone and modem. In some tests I did recently, there was practically no difference in performance from connections at the engineers socket, master socket and extension; using different filters seems to have more effect - even new ones of the same model seem to vary in performance (usually by affecting the CRC error rate).

You could always give it a try if the new filters don't help on maxDSL.

It's reassuring that PN will offer that if necessary, but it's worth a punt with the new filters first. As mentioned, the 2700HGV would be the one to stick with.
Good luck.
ps spraxyt got there first, but I'll post anyway.

Re the fixed-rate option; perhaps something to be tried if my current dslMAX doesn't regain its normal performance after a week or so; there were signs that it was beginning to drift back up from 800 a few days ago......to 992 this morning....towards the norm of 1300. And until I swapped the filter today (and back down to 800), I had re-reached a profile of 750 - only just less than the 1000 norm.
Do you think I should be optimistic about possible BT infrastructure improvements to the broadband delivery to homes?.....in the near future?
Cheers

I think the term "when hell freezes over" is appropriate for us people out in the sticks

I tried an XF-1E filter, but it didn't improve things; rather the reverse - it increased the attenuation by 0.2DB and (possibly) increased the CRC rate. I say 'possibly', because when trying any form of change, I don't know whether the changed item is the cause of any degradation, or whether the ADSL self-adjusting mechanism is kicking in (say as a result of a filter change disconnection/reconnection).
I've decided to give the 1M fixed-rate line a try out, and will put the results up in due course. At the very least I might get a known-performance baseline on which I can assess different modems/filters.

but as btw have shareholders to keep pockets full this would never happen and what do they care if a gd % of the uk can only just manage 2mb as long as the rest swamp the stats with the soon to come high bandwidth and bump the avearge speed up the whole country ofcom will not give a dam
