Mine doesn't but at 450m from the PCP it wouldn't have been available to me.
That doesn't sound like a recipe for a fast connection
I've actually been poking around online this afternoon trying to find a cabinet as I've been asked to go and look at a property which allegedly has slow internet. It's on G.Fast and the BT checker reports a recently observed sync of 330/50. The last FTTC sync on the previous service was 80/20. The checker also reports a downstream handback threshhold of 330 so it's got to be incredibly close to the cabinet.
The technician from the contracted IT support company who visited a couple of weeks ago reported a downstream speed of 22Mbps and upstream of 20Mbps. I'm putting money on that being a wi-fi result and bad wi-fi being the root cause of all the reported issues
