Intermittent Internet Drops - No Ranging Response received

[basuru]

Hi, I've been having internet drops for about a month (Had VM for 5 or so prior without issue.)

A few days after getting the Hub 3, I bought a Nighthawk Mesh System, which has done great.

The last month, I've been losing connection, though the route doesn't show any error lights, and the Mesh System is connected to itself (If the Hub 3 is off, or is resetting, the Mesh system shows an orange light). The PC however notices the lack of Internet.

I've seen other people have posted logs, here are mine:

I also noticed on my Netgear I have a bunch of attempted DOS attacks, fraggle, I think? Probably a separate issue, and I guess the router noticed them? I dunno. Please someone help.
