Rf noisy electrical devices don't just emit in the adsl2+ band

Any advice please on what to do further?

First instance is turn off stuff and see if things improve

Power the modem off for 10 seconds then on again.

Best way to do so without tripping DLM?

Should be 30 minutes really to avoid DLM.

That is the best way, unless you want to leave it off for 30 minutes. But do not repeat within 24 hours.

Power cycled both router and modem for 30 seconds and still the same.

You mean this is still the same? http://i.imgur.com/lhQBmAs.png

That looks to be caused by some RF interference. It could be a failing port in the cabinet

Yes it looks like that still.

I'll upload it anyway

The SNR before was 4.1 @ 49mb

The SNR is now 6.1 @ 39mb

I think your line had resync and now the target SNR is connecting at 6.1db and dropped the speed down due to the loss of the 2dB SNR. Crosstalk is my guess to be honest.
