I have a Vigor2860ac, Firmware Version 3.8.4.2_BT that went live with Infinity 2 on 4/1/2017. The line has never made the guaranteed minimum speed and I have and a second OpenReach engineer visit is booked for next week. I am c300M from the cabs and the last engineer thought I should be getting 70 Mbps, currently I’m getting 49 Mbps.

My DSL Status Tone Information page shows a significant notch in the D1 band, only 2 bits around bin 600. I believe the band should be flat and the notch indicates a bridge tap on my line. I’d be grateful for any feedback from other Infinity users regarding the characteristics of their D1 band.

Regards Steve
