Hello,

I moved into a new home about 2 months ago and have had a constant battle with the network since. ISP has been pretty responsive but ultimately not helpful, with 6 techs coming out and not actually fixing anything. The last tech came out and said there was 30 volts flowing through the outer channel in the coax cable from inside the house, and that an un-grounded outlet is likely the reason for my issues. My modem is the only device receiving the coax within the house and it is plugged into a surge protector, which is plugged into a grounded outlet so I don't see how the coax is getting the additional voltage. There are un-grounded outlets in the bedrooms of the home, but as I said there aren't any devices connected to a coax. In addition, last weekend I didn't notice any issues with my connectivity and I was playing games all day Sunday as well as Monday.

I have been running ping plotter for a bit and it looks like there may be an issue with the cable in the home as my pings to hop 1 are coming back with high latency, jitter, and packet loss and I am wired directly into the modem. I know the modem isn't the issue, as this is the 3rd modem in 2 months. First two modems were ISP provided.

I took my own reading of the coax cable and I saw 6.5-7v on both the stinger and sheild.

First Hop (big outage around 8:30 and 9:15 is me testing voltage on coax).

Here is a screen shot of pinging pingplotter and google.

Additional info:
Modem- Netgear CM1200
Router- Netgear Nighthawk xr450 (PC not wired to router)
-Power Cycling the modem will restore service sometimes, but usually not for more than 20 minutes.
-During severe "attacks" no amount of rebooting modem helps.
-Sometimes the issue will seem to resolve itself for a while.
-I have been told by ISP all cables between modem and telephone pole have been replaced, and the first hub has been checked and only one other home is receiving service, and they haven't reported any issues.
-Between 10AM and 4PM on day 1, all electronics not connected to PC were unplugged, and all power to appliances was turned off at the fuse box. Problems still continued.

I am at a total loss for what could be causing this, any help would be much appreciated!
