I noticed this morning that my attainable rate has changed upwards from around 60,000 to 102,608kbit/s down and from about 20,000kbit/s to 38,491kbit/s up. I've been on FTTC (BT Infinity) since January and the modem has always reported the lower attainable rates (last check was at weekend)
What is likely to cause such a large increase in attainable rate as nothing has changed in my house? There was an engineer working on my cabinet this morning but I assumed this would just be another FTTC install nearby.
I should point out that when the BT wholesale checker had its cap temporarily lifted a few weeks ago I was getting an 80/20 estimate but my modem was reporting the lower attainable rates above.
