Thank to all for the replies,
These spikes mostly occur during the evening and overnight, but they even show some during the days on the weekends. Never during 'office' hours weekdays.
No computers or other wired or wireless devices are on at all and I don't have a samknows blackbox.
It's not the router time being adjusted automatically and nothing is showing up on the router logs. Disabling dos attacks and spi doesn't stop it either. Disabling wireless doesn't stop it, even though I'm confident it's secure it was worth a try.
So I'm at a loss as to why these occur, and why they suddenly stop for a small perod of time. I can't see any problems using the traceroute tool from this site either.
Looking at maniacs graph this, like others have said, looks like to be Aquiss or Entanet. My findings are that comparing maniacs live graph to mine, the little drops occur on mine and maniacs graphs at exactly the same time for the same period of time.
