Only thing i see is the SNR margin has dropped slightly, would that make any difference?
I would have thought my Interleave depth would have dropped, but it's still at 16.

The small change might be due to syncing at a different time of day, even with a really good line like yours there will be some 'noise' at times seen by the modem.
At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

Your line stats look really good. You are right at the top end of sync speed so you are doing very well. You must be close to the cabinet. Look at your attainable speed (109 Mbits down and 40 Mbits up). Once the faster products are available, you will be able to make full use of them. Very lucky.

Quote from: darklight What is the best time of day to sync (reboot) modem? to get best line stats.
Never. You're not going to get anything better than your current stats on the currently available fibre products.

I'm not new, i've been on FTTC for just over 2 years now with plusnet, so i guess my attainable rate will stay as is, unless it starts to fill up anymore.
