I have G-Fast Broadband through Zen, which was meant to give me speeds of 150 Mbps. After upgrading and waiting a few weeks, I found my speed wouldn't exceed 100Mbps.
Long story short, the engineer said I wouldn't be able to exceed 100Mbps (mostly due to distance from my house to the cabinet) as that is the line speed he was getting when he measured the speed at the master socket. I spoke with Zen and renegotiated my price, staying on G.Fast. I'm now getting up to 80Mbps +/-10Mbps.
I have now seen on broadbandcheker a column called "Downstream Handback Threshold" (DHT) which states that my DHT with an impacted G.Fast Range B should be 168.8Mbps, much higher than the 100Mbps I'm getting. Next to Bridge Tap, I have "U". I assume that means "Unknown". Not sure if that matters in this situation.
I don't really understand the implications of DHT, but was hoping someone could explain if I am able to get Zen / Openreach to "fix" my line? I'm not sure what my rights are.
