Circle on Netgear slows down your speed

I believe this is true also.  I have a new R6700v3 router and after 2.5 days, the speed slows down to less than 100 Mbps.  I have to fully reset the router using the reset button not knowing what causes this.  I contacted Netgear support trying so many things without luck for days and weeks.  So I reset everything and kept factory settings without Circle and the speeds seem to be what I subscribed for Fios so far.

Instead of Circle, I am using OpenDNS which is also free to use.  Just update the DNS server addresses in the router settings, and that should be it.  One can customize what to restrict within their control panel.

I wish I knew it was Circle that was causing this and wasting so many of my hours....not to mention runing the image of Netgear.

Thanks.
