So glad to have stumbled upon this thread!
I'm currently using Plusnet FTTC, but the cab I'm connected to is right at the other end of the village (approx 1km D side length). On a good day I could get around 25mb, but that has been in rapid decline in the last few months and its around 10mb now. Because the cab feeds most of the village, crosstalk and peak loading seem to be big problems in addition to the excessive length. There's another cab less than 100m away, but alas it doesn't feed me, and the chances of any copper rearrangement or FTTP are probably about nil, all the really remote places round here are getting FTTP but we fall into the category of "crap, but not crap enough" speeds.
What we do have at this end of the village though, is a Three mast in line of sight, it was even upgraded last year! I've been a customer of theirs for a while, so might even get a deal out of them. The 4G signal at home on my phone is excellent and I often turn the WiFi off when browsing on my phone and revert to 4G for a bit of speed. Only got 2 months left on my contract, so assuming the product still exists then, I'll have it
Working from home and IPTV will be once again possible hopefully (my fault for moving from a city to the country!)
