Frequent Packet Loss
I've contacted chat support 6 times now with no fix.
House sporadically sees high packetloss even when there is no "area outtage" alert for my neighborhood in the Cox portal. Modem shows a crazy high number of uncorrectables and correctables. I was told to replace my modem- $160 "fix" and the issue persists. Then every other chat support chat ends with support telling me that an issue has actually been detected in the area and to stand by. The packetloss never subsides, even when the area outtage alert is cleared up..
I have ruled out hardware on my end as being the culprit(s). Packetloss on both wifi and ethernet, packetloss even when no issue is detected in the area, Support rebooting my brand new modem doesn't help with the ongoing packetloss, the modem is at the closest coax port to the Cox junction/demarc box (with the router right next to it over a healthy ethernet cable) and as far as I can tell there are no splitters/amps on the coax line.
I need a technician to test, and likely replace, the Cox coax/hardware between the tap and the house. The technician doesn't need to enter the house if they don't want to, I have yet to see any evidence pointing to something inside the house causing the issues.
