I believe that the DLM will at some point aim for a 3dB SNRM on ADSL2+, but whether that will happen with your line depends on your attenuation/quality parameters.
I would try a disconnect via the router interface followed by a reboot/reconnect in a day or so to try for a better sync, but don't keep doing it or the DLM might interpret it as line problem and slow it down even further.
Make sure that your IP profile (as reported by the BT diagnostic speedtester) and your Plusnet profile (in your Account details) are more or less aligned.

Are there any ill effects of not having your IP profile updated by PN during the training period?
Thinking about it as I type - if PN hold my IP Profile at 7.15mb while the exchange keeps trying ever higher sync rates, could this result in a faster connection at the end - i.e. DSLAM tries 12mb, I dont get disconnected or lots of errors, as my data is only being allowed through at 7.15 by PN. So DSLAM tries 13mb, same result - and so on... until the training period ends, Im synced at 24mb, and have a PN profile of 7.15mb. Then I ask pn to update the ip profile, and hey presto a 24mb connection - albeit probably one full of errors and disconnects that werent picked up during training due to the stuck IP profile at the time

Looking better but everyone else I know on ADSL2+ has an SNR of around 3dB. Do I just need to have a bit more patience?

P.S. Any chance you could wave your magic wand and deliver me FTTC or FTTP?
