Re: Internet Drops - Huge amount of correctable and uncorrectable errors
The tech that was out here today for me told me T3/T4's relate to the coax connection to the outside tap. Inspect all the coax leading from your modem, to outside, to the tap. See if the cables are insanely weathered/crumbly.14Views0likes0CommentsRe: Frequent Packet Loss
Update on this, I got a service rep out to the house. They immediately pointed out that the Cox lines from the tap to the box on the house, and from that box to the hole in the wall were terribly weathered. After he replaced the cables, the problems persisted. He also ruled out all hardware on my side and dropped a bunch of jargon claiming that the problem was at the tap and is going to put in a ticket to engineering to check/replace that tap.0Views0likes3CommentsRe: Internet Drops - Huge amount of correctable and uncorrectable errors
Extremely similar issue here. I've contacted support now 7 times about this. They just tell you to buy a new modem and after you buy that new modem, they just want to keep rebooting it to clear the counters... They are finally sending out a tech tomorrow to inspect the lines between the house and the tap. I will update here with any findings. Update: 1/12/2021 I got a service rep out to the house.

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.
