Upstream blinking
So I picked up a AC 1750 c6300v2 cable modem and I just activated it through spectrum, went to netgear genie and set it up as well. Worked fine for an hour or so and then all of the sudden it goes out...
Blinking indicates only 1 channel is locked and its searching for more.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, bad/old/cheap connectors, or corroded connections. Replace them if you do.
If you can, simply connect the modem right where the coax comes into the home. This prevents wiring in the home from being the issue. And some ISP’s charge if the wiring issue is in the home. So this helps prevent this.
After that, get a screensnip of the cable connections page and event logs and post them back here.
