billgates: hmm. I will wait for 10 days and see if DLM does push my sync rates up. Sitting at 26.9Mbit/s for downstream. Naked VDSL2 connection with VOIP and no master filter. Less than 350M from the cabinet.
That's a terrible sync rate and attenuation if there really is only 350m of copper between you and the ISAM - based on that you're significantly further away or have a wiring issue somewhere.
