I wonder if it could be anything to do with the latest firmware on the modems because I remember interleaving was removed from my line the day after the update. Prior to the update the interleaving depth was somewhere around the 1300 mark and had been like that for over 6 months.

What AV/firewall software is running, the spike in the httpx6 is not unlike what you can see with some av checkers putting themselves in the way.
Be interesting to see the ookla graph
I use KIS 2014, this is with it disabled and everthing seems smoothed out (Every result you have seen in on wireless BTW so that might have something to do with it)
