I've read somewhere that the firewall senses an x number of connections before flagging them as a DDoS? Is that what I'm seeing here?

The log is usually clear when nobody has used the internet, it's only when we're home that the problem occurs. Here is a recent firewall security log, the log coincides with the disconnects. My router appears to absolutely hate webpages. If people in the house are only streaming or gaming the connection is fine. I notice it happening most often when browsing webpages before it kicks everyone offline. When the internet cuts out I get no icon or any sort of prompt indicating that the internet is out or having problems on my desktop/laptop, however I do get a 'this page cannot be displayed' and if someone is streaming their streaming connection cuts out.

I've called my ISP and they insist theres nothing wrong with the modem they provided. The router is brand new replacement for an old netgear router that fried and the new router started having problems within days. I'm having this problem with both my wifi and Ethernet connections where my internet just cuts out across all devices for several minutes or until I reboot my router. Number of connections: 3-7 at any given time, 2 desktops, 2 laptops, and 3 smart phones.
