AC1900 C700v2 Connection Drops
I have had the Nighthawk AC1900 C7000v2 for awhile now and what seems like everyday now, I will lose connection and have to sit for a few minutes untill it reconnects. This has been happeneing for as long as I can remember but am getting tird of it finally. When diagnosing the problem I have found out that the "upload LED" starts to flash when connection is lost. It will flash for a minute then the internet and download LED along with the upload will all three shut completely off and a couple minutes later they will come back on and my connection will work find untill it happens again in 20-30 mins. Is it my ISP or is my router being the issues? note: I have not contacted my ISP yet and I have 1-24 download channels locked but only 1-4 upload lock while 5-8 are unlocked.
If you have any splitters, amplifiers, or attenuators in the coax line remove them.
Check the line for kinks, bends, poor/old/cheap/bad connectors. Also, check for loose connectors.
Move the C7000 to right where the coax enters the home and connect there.
Reason I say this is your log is showing line issues, power lissues. The dynamic range window violations are when power goes above/below spec. And you have many t3/4 errors. This together indicates a line issue/cmts issue.

Do you also have your logs? The cable connection page is just a snip in time of whats going on at that time. If the power is fluctuating and causing reboots/drops, the logs should show that.
I can't seem to get my logs to send via the email settings in the router but I do notice alot of DoS Attacks on the logs.
Here a screen shot, it just happened as described in inital post. Upload flashes for a minute, then all three upload internet and download flash. then they shut off and come back on and everything works fine till it repeats.
I think its under event log. shows the modem side of it. That's the router side
