Now I have an additional outage notification. I'll update afterwards. At least this shows they know about it, right? Re: It's time for regular packet loss again! During my [Cox Contractor] service call yesterday, they replaced the line from the pole to the house. There was no change. They said they couldn't escalate it due to a ticket already being entered two days ago. I called Cox, and they had me switch modems back from Cox's own Arris TM3402A to my own Arris CM8200A (also DOCSIS 3.1) to see if anything improved. It didn't, except I got a slight boost (1-2 dB) on my signal levels. S/N is good also at around 40 dB on most bonded channels. Next thing I know, there's an outage notification in the Cox app: Once the notification was cleared, I set away my Pingplotter again.... it looks like it was great overnight, and then after 10 this morning it all went to heck again: The saga continues...... Re: It's time for regular packet loss again! I understand that. They should have a star system in their customer notes so this stops wasting time and money. Something like: * = doesn't really know what the internet is. ** = has heard of TCP/IP. *** = average computer savvy user. **** = sets up their own modem and router. ***** = knows Cisco IOS, network guru. I wonder how much Cox could save on initial service tech calls by doing this....? Re: It's time for regular packet loss again! I understand completely what you're saying. I don't have a real speed problem. Latency and speed aren't too related, although your average speed will drop with excessive packet loss. You can have the best ping time in the world, and if some of those packets get dropped, especially in UDP or other streams which don't use acknowledgements, you'll feel it in gaming, streaming, etc. This is a common occurrence for us here. Squirrels chew the cables, causes opens, shorts, intermittents, and that compounded with line noise just makes the whole internet experience poor. My pain is with this happening multiple times a year, and having to jump through hoops to get it looked at. Re: It's time for regular packet loss again! Pingplotter Pro results so far: It's time for regular packet loss again! Hi there, if you want some backstory, read these: Cox Line Quality Issues - Regular Upstream packet loss - Internet - Internet Forum - Cox Support Forums Line quality issues are back again... - Internet - Internet Forum - Cox Support Forums [OK] Cox line quality issues are never-ending - Cox | DSLReports Forums Welcome to episode three of "it's packet loss time again!" but this time with dishonest/ignorant service agents! It's a common problem in my neighborhood. Happens almost all the time, but two or three times a year my Cox gigablast service gets to be unusable. It's generally due to squirrels chewing the lines, and/or noise at the local node. It always takes a line tech to fix this, but it seems impossible to skip a house-call, even with my account history. So, I contact support. After getting disconnected a couple of times, and trying to tell them I don't need another new modem, we establish that I need a technician to come out. I try to explain that I'm an expert at this, and it'd be really awesome if we didn't waste Cox's time, and my time, having to handle a house-call. I ask "to be clear, this is for a line tech, and not a regular technician house call so I don't need to be at home, correct?" "Yes sir, that is correct" came the answer. Excellent I thought. I later went on the Cox website to check to see if there was any appointment data.... Looks like a house-call for a TV problem. TV? I don't even have Cox's TV service! Here's my line quality, based upon pinging 1.1.1.1 in my router. This is the last 7 days: Quite a lot of T3 timeouts in my modem log also. Signal levels in the modem: I guess I'll make sure I'm at home in case a regular tech comes. Boy are they in for a lot of data. I hope they're alert! OEC Fiber is installing in my neighborhood. It's VERY tempting, but I've been with Cox for 10 years now, at several different addresses. There is nothing to be said for customer loyalty any more, and they surely don't keep (or read the) notes on my account. Re: Line quality issues are back again... Hi Dave, It looks like whatever they were doing yesterday fixed the issues. The last 24 hours on my router's conmon monitor look like this: The same is reflected in Pingplotter: Also, the last T3 timeout I see in the modem event log was around 6:30pm last night: 5/4/2021 18:29 82000200 3 No Ranging Response received - T3 time-out;CM-MAC=c8:63:fc:d6:03:dc;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1; Re: Line quality issues are back again... Update, May 4th 2021 @ 5:25pm This morning, I noticed increasing packet loss issues, so checked the Cox app. Sure enough, there was an outage in our area. I felt encouraged by this - maybe they’d noticed, maybe enough people were complaining, I don’t know. Anyway, have a look at this timeline... https://ibb.co/Ybgd8pV And at the same time, I have been running the continuous Pingplotter: https://ibb.co/nBrTQp7 Curious... I guess we’ll find out if this is a fix or no! Re: Line quality issues are back again... Update, 3rd May 2021: PingPlotter is showing the packet loss also, within the Cox network. https://ibb.co/93Ng4p9
