I have a long line to the exchange and used to get 1.25Mbps on ADSL2+. FTTC finally arrived and BT forecast 27Mbps even though I am over 1km from the cabinet. I ordered Infinity 1 and the day of installation came and the BT engineer showed me that the speed was in fact 27Mbps as forecast. Later that day I did a test on Speedtest.net and the download speed was around 26Mbps, and upload was around 1.2Mbps.
A day after the installation the download speed had dropped to 15Mbps and 9 days later it is still around 15Mbps and the upload speed has fallen to 0.7Mbps, slower than when on ADSL2+. No changes have been made to any wiring or sockets.
I realise there is a settling in period but can anyone offer any advice re:
Is it normal for the speed to drop so much after the first day?
Why is the upload speed so slow?
FTTC has only just become available in our area so a lot of people are being connected. Could this have an effect?
Is the target noise margin 6db as with standard ADSL?
Should I take this up with BT?
