Just recently my line was enabled for ADSL2+, and I was orignally quoted the below as the projected speed by BT and by my ISP, Plusnet.
Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 17Mbps; typically the line speed would range between 10Mbps and 19.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1.5Mbps and downstream line speed of 17Mbps; typically the downstream speed would range between 10Mbps and 19.5Mbps.
All was going well within 10 day training period as I was seeing speed of around 15Mb.
6 days into the training period my router gave up the ghost, so i replaced the D-Link DSL-320B with a Draytek Vigor 120. This didn't cause any problems as my speed was still maintained at 15Mb. On day 7 we then had power issues, our circuit breakers kept tripping which we eventually traced to a faulty socket which was replaced immediatley. From this point on our speeds dropped to around 12Mb.
I contacted Plusnet about this and they indicated that the speed should return after 3 days of constant connectivity, but nothing happened. It would seems I have dropped a profile with no sign of it returning. Plusnet then suggested an SNR reset. This is now in day 9 and I have seen no signs of the speed increasing.
Here are my line stats from BT, Plusnet and the modem.
Draytek Vigor 120
Up Speed: 1171805
Down Speed: 18812619
SNR Margin: 5
Loop Att: 23
IP Profile for your line is - 15000 Kbps
Plusnet Current line speed: 14 Mb
We plug directly into a filtered NTE5 faceplate.
Am I just been picky and should settle for the current speed, or shoud I be seeing faster speeds than I currently am. It's almost as though some kind of limit has been place on our line.
All my neigbours projected speeds are still 17Mb including those who live further away, although our now says 14Mb.
Any helpful advice would be appreciated.
