Remind me what the symptoms were?
- disconnections throughout a day and night, usually at 27 or 57 minutes past and before, respectively, the hour, the most common one being 12:57am
- outbursts of noise on the line, resulting in CRC errors and 50% of severe CRC errors for every 1 CRC error. In other words: for every 2 errored second, there was 1 severely errored second
- this outburst of noise would appear at regular increments, as if corresponding to a boiler firing up/heating up and then resting; a constant cycle. However, Black Sheep said it was as a result of cross talk
- Min. effective data rate on Fritzbox incrementally reducing to just 3 kbit/s from 54989 kbit/s. So, the speed would reduce to something like 30000 kbit/s and then 15000 kbit/s or something very similar, until it remained 3. This doesn't mean that the overall speed was reduced, but presumably means that at some point, the speed of a connection was just 3 kbit/s.
- when I pick up the phone and dial a number, errored seconds appear on the upstream
- when raining/windy, of which there's plenty here in the Lothians, we'd sometimes see an increase in errored seconds
- issue getting worse in the winter
- lots of FECs, which suggests cross-talk/re-transmission
- on the GAE report, it shows as 'interference detected daily'
If I remember anything else, I'll add it here.
They don't think it's REIN. He called it 'interference', whatever it means. On their systems, this shows as a Higher Resistance fault, but I only know that because when Openreach engineers from the Borders were called in to help in the area, they told me that. The others maintained the line is fine and it was a WiFi issue, which they stated 13 times in their reports. (You'd think Plusnet would get suspicious that a WiFi issue is causing so many problems that an Openreach engineer is called in so many times, but this shows that there's no sense of ownership in modern ISPs, with some faults being picked up by new stuff not knowing the previous history etc.)
