My stats 1 week before ADSL2+
It should be noted I did have major line problems and frequent disconnects a while back (after a thunderstorm), I think plusnet raised the target SNR which helped, but i would still lose sync whenever the phone rang. Turned out I had an old PBX mini-exchange connected (long story), now this is out of the picture I held sync for 6 days before being moved onto ADSL2+.
I think BT have me on an IP profile of 5.5meg, it was around 7 (i used to sync at nearly max speed). Surely with these stats I should be syncing higher?
I've raised a ticket with Plusnet and copied my stats. Basically I want my line re-set as if its a new connection and let it set at whatever speed my line supports (the exchange is just down the road from me) so hopefully something a bit better!
Oh and i ran the DMT tool to check the SNR for around an hour, it reported a 0.8dB average fluctuation, at 6pm - 7pm, with incoming and outgoing calls on the same line.
