If it was just 1 device doing it, I'd be more inclined to suspect hardware failure.
but if both of your devices are, I'd be looking at the lines/boxes. I know they've been out to inspect the line but it could be a box/cmts causing the issue.
Isp's have been switching to docsis 3.1 devices that use a different channel versus the C7000 is a docsis 3.0 device.
so the modem they installed could be a 3.1 device and allowing the downstream connection on a different channel.
Plus it could be programed to connect on different channels.
so while it might be running fine, the ones your modem is one could be having signal issues.
do you have a screen snip of the c7000's cable connections page and the event logs?

My ISP is old and doesnt have the 3.1 standard. They actually recently got bought out by Spectrum and I will be switching to them at some point in the next 6 months or so hopefully. They did more then inspect the line, they ran brand new lines all the way to my house. Unfortuanetly I am no longer connected to that modem since there modem is working fine and i need stable internet for work. I could swap my ethernet cord over to the nighthawk when i get off work in a few hours and try and grab a pic of the logs i should have saved the one from the other day. But it is odd for mine to do it as well as my sisters with hers only being a few weeks old.

Agreed, which makes me think more of a line/junction/cmts issue than a router issue.
What arris did they replace it with?
You might be surprised with the docsis 3.1 device. the jump from docsis 3.0 to 3.1 was fairly cheap in comparision to going from 2.0 to 3.0 or even to the newer 4.0 service (when it comes)

They replaced it with an Arris surfboard DG2460a. I wish they would support 3.1 because before i bought the c7000 i had a different nighthawk modem cause i have a nighthawk gaming router and that modem had 3.1 but they could never get it to work so i eventually just ended up using the c7000 as the modem/router. When i get spectrum I should be able to use 3.1 but i have no idea when there going to build out to me since they just acquired my isp like 2-3 weeks ago.
