A few weeks ago I noticed that my sync rate would no longer get over around 11300kbps despite nothing apparently changing at my end.
Over the last week or so, I've been backing off the forced SNR change on my router to see what happens following a hunch. Previously, I'd set it at around 55% of the MSAN set SNRM and it would sync at just over 12000kbps with the actual SNRM at about 3.7dB. At 54% now, it won't get over 11300kbps with a very, very similar SNRM. I've been backing it off 1% at a time and am now at 58% and it still hits the same/ very similar sync speeds with the same/ very similar SNRM figure.
MSAN target SNRM is displayed as 6.6dB and the router is a Billion BiPAC 7800N. My ISP is Vivaciti and I'm connected to Broadcom kit in the exchange.
The only change I've noticed in this period is that the upstream SNRM has gone from a inconsistent 10dB to a very consistent 6.5dB.
Has anyone else seen this? Or does anyone have any ideas?
