I have been on BT 80/20 service for 22 months, until a month ago my router was showing the DSLAM connected at 80/20 and my d/l speed was around 74 MBps, I notice now that the DSLAM is now fixed at 74/20 with d/l speed at 65 Mbps, which is my minimum guaranteed speed from BT, and because of this they will take no action in looking into why the DSLAM is at 74 MBps.
Should I expect my DSLAM to be 80/20, my router is showing my SNR at 6db receive and 9bd send, with Line attenuation of 13db receive and 14 db send.
In the meantime BT offered me their ultrafast Fibre Plus product with 100 MBps only to discover this is a mistake on their website
TIA
