Ping Spikes and dropped packets
Hey guys! So this started about 4-5 days ago where my nighthawk C7000V2 (Firmware V1.03.01) would intermittently have massive packet spikes and dropped packets. This isn't just with gaming . Since I...
do you have a screen snip of the cable connections page and event logs?
that helps us check the connection back to the isp.
they're great at saying "its not our line".
And it might not be.
Check you coax line for kinks, bad/old/loose connectors, moisture in the line, etc.
Also, if you have any splitters, amplifiers, or attenuators, remove them from the line. preferable, directly connect the c7000 to where the coax comes into the home to prevent the wiring in the home from being the issue.
Hello! thank you for getting back to me.
I went ahead and I checked the coax connection to the C7000V2. I even double checked the outside cable line to make sure that there wasn't any damage to the outside box. Doesn't appear to be anything out of the ordinary. I just have the one coaxial connection directly to the modem/router no other splitters, amplifiers, or attenuators.
Here's the output from the event logs below kind of a bummer they don't have a export option so a copy and paste will have to do.

Here's the screenshot of the connection page:
really appreciate the help.
Is there any documentation to help better understand the logs?
