Kitz,
This is what happened:
* Up until the 7th G.INP was running fine and had given an increase in sync speed of 6-7 Mbps
* I'd been seeing very low upload speeds below the FTTC A Low level and as PN have been looking at it for some 2.1/2 months I put the HH5A on to prove it wasn't the SBG3300-N, the HH5A actually dropped my upload a further 1Mbps. G.INP had been happily running on the SBG3300-N for around a week and again for about 6 days on the HH5A.
* Around a week after putting the HH5A on at 5am on the 8th - G.INP was removed from my line. Line rate was 52 Mbps before with interleaving and the same after G.INP was applied. Connection rate was around 44-45Mbps with interleaving, with G.INP it was 51Mbps. Line rate was always at 52Mbps and remained that way until the DLM reset on the 11/04/16.
* HH5A was constantly rebooting but it did not affect the line rate. The HH5A has always done this on my line, when I was on Infinity it did it sometimes 4 times per hour. Hence I bought the SBG3300-N.
* The D7000 was put on my line on 08/04/16 and my line rate was still 52Mbps.
* I've had an open ticket for upload and sudden sporadic SNR fluctuation in the evenings open with PN since the beginning of Feb 2016.
* The OR visit on 11/04/16 was because the upload speed was low, after a DLM reset my line speed has dropped, currently at 47Mbps but I expect it to drop further this evening as it did yesterday and more once interleaving kicks in.
* Upload is slightly worse, download speed was very unstable on every PN gateway last night but seems more stable today but line rate on the download is far worse after DLM reset.
Finally:
DSLAM/MSAN type: IFTN:0xd086 / v0xd086
Hope this helps, if not fire away
