Over the past few months I have had a Netgear D7000 connected to my line. I've always been a good few Mb off the max rates such as around 73Mb down and around 16.5Mb Up. Both sitting bang on 6db so I assumed that would be me at the max possible.
I went away for work for a month and came back to a few days ago to see that I had a resync 5 days ago. My speed for downstream remained the same but upstream had increased to 18.5Mb but SNR was sitting at 4.7dB.
Last night, I have had another resync retrain reason 1 which I assume is DLM intervention. It appears my down sync has remained the same but my upspeed has now increased again to 19962 and SNR has also gone to 6.2dB.
Any idea how I've gained SNR and speed? I'm not complaining as this is the best I've had it. Full stats below for previous and today:
