In the summer I had a similar problem and Kcom Eclipse my isp wanted me to go back to ADSL from ADSL2 to try to see if my long 4.3kl line was better, it was.
I ask to go back to ADSL2 again (after I thought a noisy line had been fixed) the Downstream is steady but 'upstream' is all over the place, errors are not bad.
I think the REIN issues have been sorted on my neighbors security camera.
My line profile should be 6dB + 6dB but the up keeps going to about 18dB ! .
