Would I be correct in saying that the cause of my current 30Mb/s throughput cap cannot be interference? My understanding is that the connection speed is (give or take TCP overheads) what the line is capable of and if there was interference my modem would be connected at around 31Mb/s?
FYI here's one of the graphs I got from my modem:

This is the same fault I've mentioned previously - it repeats on the 19th of every other month (June, August, October and now December) and takes a few days to clear - or at least a few days after it starts a modem switch off for 20 minutes fixes it.
The most annoying thing about this is Tech Support's insistence that it's interference and the only thing they can do is send an engineer round to check my line. They are reluctant to do that (so am I) as the line test shows as all clear (quelle surprise). At that point they tell me I'll have to live with it and that pretty much ends the conversation.
Just because he could. RIP.
