VDSL speed lower

[frater]

Today I tested the 6.80 firmware for the first time.
In the last year I had a sustained download rate between 108~111 Mbit/s
In that time I had various different firmwares.

Now my download speed is 84 Mbit/s
The upload speed went down from 32 Mbit/s to 31 Mbit/s

I may be going back soon if this doesn't change. (It is possible this is something automatic at the provider's side after a few LoS's.
Will report here if that's the case (could need a recover of 24 hours)

edit: 20-02-2017

I just tried "previous DSL version", but the speed stays at 84 Mbit/s
The only thing to test now is reverting to 6.52int

BTW... This is strange:

I just flashed another 7490 connected to another VDSL2 line with similar speeds.
It took a long while (5 minutes after getting access using the webif) before the line was trained, but it went straight up to 111 Mbit/s and there's no difference in the 2 DSL pages.

I tested the connection that reports to have 84 Mbit/s with http://speedtest.net and it reported a throughput of 102 Mbit/s.
It seems there's something wrong with the reporting of the speed. Not the speed itself.

Even stranger and worrying is that it's only 1 modem and not the other.
For now I'm assuming I have a 109 Mbit/s connection.
