As others have stated there has been a significant degradation of service in the Las Vegas area with Cox. Multiple restarts of cable modem and router does not resolve the issue. My VOIP phone is constantly losing signal, my TV which I stream Amazon Prime on constantly freezes and/or has audio cut out. I had issues literally 2 months ago and a Cox technician came out and worked on my signal levels, so I am 100% certain it has nothing to do with the wiring. My cable modem is only a month old, my router is 2 days old. This issue has been going on for almost a week now (hence why I purchased a new router in hopes that it would resolve my issue, thinking maybe my old router was dying). Connecting directly to the cable modem does not seem to resolve the issue as high ping response times and timeouts still occur.
At this point I don't know what to do anymore, I rely on my gigablast service since I work from home and need to have internet connection to VPN into the office. Is there anyone at Cox that can get to the bottom of this? I am sure you can see the numerous posts by other uses complaining about issues in the Las Vegas area. Get your network engineers to check your backend hardware, this is not an isolated issue and is becoming extremely frustrating, to the point that I am willing to sacrifice speed for reliability by switching to another provider.
What model modem do you have? Can you post the signal levels from 192.168.100.1?
Signal levels look spot on, although a little on the high side. Anything in the logs?
Also, I notice that is only with a uptime of 5min. Do you get any uncorrectables over time?
Nothing out of the ordinary, the signals were all checked by a Cox tech who came out here 2 months ago and spent a good 2.5 hours removing coax splitters and measuring signals with his meter, from the curb to the box outside to the outlet inside. My old modem ended up bricking itself when the tech was here so I used a Cox panoramic modem while I waited for my new MB8600 to arrive. Once the new modem arrived I plugged it in and activated it and I did not have any sort of issues until about a week ago when all the packet loss issues began.
I removed my Netgear router and went with a Ubiquiti EdgeMax 4 router. I was really wishing that my Netgear router was starting to die but that was not the case as the new Ubiquiti router experienced the same packet loss/ping timeout issues.
The only other thing I can think of that could possibly be wrong on my end is maybe the new cable modem is dying, which would seem rather unlikely. I do have another cable modem, an Arris SB8200 (which was sent to me after I RMA'd the one that bricked itself). I suppose I could try it but it just seems like every couple of months something goes wrong which makes the internet connection unstable and at times unusable.
I will check the uncorrectables later today before trying out the new modem.
The issue seems to have resolved itself... Literally as soon as I purchased Cox Complete Care online my modem rebooted and there are no more ping timeouts... Seems rather strange.
