No. That is incorrect logic.
Yep, the logic was incorrect - but I'm trying to answer a question I have (domain knowledge is the problem). I can see the pattern I want to query, but am having difficulties putting the correct question.
I'm also putting in old information from before I had the bridged tap removed, and before I had stats from the HG612. I'll try again and see if I can word what I'm trying to find out.
1. When rain happens (and especially noticeable when it's snow) my normal SNR drops as if there is crosstalk, using the gif you gave to identify the closesest approximation of the effect, this causes CRCs/resyncs or did before I set an upper limit on the attainable. Worst connection I've seen was about 22Mb/s : first attachment (minimum line in the graph)
2. If my line resyncs a few minutes after the starting event the speed/snr are as before and no more errors occur. The picture yesterday
3. If the line recovers on it's own, it's a gradual process over the course of 30 - 40 minutes (unlike crosstalk) : Second attachment
4. It looks like I have a split pair with someone who has a bridged tap causing some noise on my line (found, but I haven't asked them to do anything yet). This could be anything - the pairs could potentially lie beside each other for a long distance.
I can't put points 2 and 3 together (that's causing me confusion
), as they seem to contradict each other. Point 4 is the left field item - that's got to be so rare to make it unlikely many people will have seen it, and the effects wouldn't be well known.
So that's it - I can't think how both 2 and 3 can be true at the same time.
Attainable has varied by ~6Mb during the last 24 hours, but sync would've been maintained if I hadn't have got nosey.
