Uncorrectables on ALL downstream channels. What could be the problem?
I live in Springfield, VA. I have a Netgear CM600 modem and have been receiving uncorrectables of hundreds of thousands and millions in a very limited uptime (< 24 hours). I am having this problem on every channel operating between 649-813MHz. The amount of uncorrectables varies, but is still very high for all of them. Alongside this problem, I have been experiencing network instability and modem crashing about every hour or so. Side note: I have tested a different modem (Arris SB6190) and have gotten the same, if not worse, results. The event log for each modem has showed me a different combination of errors like: -RCS Partial Service -SYNC Configuration Time out -Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out -No Ranging Response received - T3 time-out Cox Technical Support, including the technician who came into my house, said that everything on their side looked good (GREEN). This problem arose after changing my Motorola SURFboard modem to something from this decade (ie. SB6190 and CM600) due to a small UPLOAD SIDE packet loss issue (1-3%) I was having while gaming online. Never any crashing until now. Between the times when these errors occur in the event log, my internet is lightning fast (besides the upload packet loss issue still being present). >These are the values forDOWNSTREAMwith the Netgear CM600 at an uptime of around 90 minutes. <tabindex=-1>Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables Uncorrectables 1 Locked QAM256 3 687000000 Hz 9.1 dBmV 39.2 dB 214828 132675 2 Locked QAM256 1 675000000 Hz 9.3 dBmV 38.5 dB 65347 12412 3 Locked QAM256 2 681000000 Hz 9.6 dBmV 39.3 dB 92489 14832 4 Locked QAM256 4 693000000 Hz 9.3 dBmV 39.3 dB 219991 161237 5 Locked QAM256 5 699000000 Hz 8.8 dBmV 39.1 dB 232634 167674 6 Locked QAM256 6 705000000 Hz 8.5 dBmV 38.9 dB 231551 125552 7 Locked QAM256 7 711000000 Hz 8.4 dBmV 38.8 dB 206782 73208 8 Locked QAM256 8 717000000 Hz 8.1 dBmV 38.6 dB 159890 36191 9 Locked QAM256 17 771000000 Hz 8.7 dBmV 39.1 dB 37129 42243 10 Locked QAM256 18 777000000 Hz 8.8 dBmV 39.1 dB 30994 4741 11 Locked QAM256 19 783000000 Hz 8.9 dBmV 39.2 dB 24894 2178 12 Locked QAM256 20 789000000 Hz 8.4 dBmV 38.9 dB 22073 3062 13 Locked QAM256 21 795000000 Hz 7.9 dBmV 38.7 dB 15069 2258 14 Locked QAM256 22 801000000 Hz 7.5 dBmV 38.4 dB 12652 1561 15 Locked QAM256 23 807000000 Hz 7.2 dBmV 38.3 dB 20874 5991 16 Locked QAM256 24 813000000 Hz 7.8 dBmV 38.6 dB 58248 76267 UPSTREAM: <tabindex=-1>Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 1 2560 Ksym/sec 17154000 Hz 44.5 dBmV 2 Locked ATDMA 2 5120 Ksym/sec 21984000 Hz 46.0 dBmV 3 Locked ATDMA 3 5120 Ksym/sec 28414000 Hz 47.0 dBmV 4 Locked ATDMA 4 5120 Ksym/sec 34844000 Hz 47.5 dBmV 5 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 6 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 7 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV 8 Not Locked Unknown 0 0 Ksym/sec 0 Hz 0.0 dBmV (I assume that I do not have the option for 8 Upstream channels because the Arris SB6190 did not even list the last 4 channels) Could this problem possibly be inside my home? The technician took out a splitter from my setup and placed my internet cable on a splitter with an amplifier. The problem does not seem to have changed though. I have another, higher-level, technician coming in 2 days. Is there anything that I can show them to help pinpoint the problem?Solved16KViews1like18CommentsPacket loss making games unplayable
Ping Plotter Blizzard World Of Warcraft East Coast Server IP Ping Plotter Google.com Ping Plotter 4.2.2.2 Ping Plotter Open DNS IP Ping Plotter www.Pingplotter.com I have had a technician come to my house and using his tool says he gets all green lights from my drop out. I have had Blizzard assure me their servers are fine but after taking a look at this ping plotter you can clearly see intermittent packet loss. So at the time the tech tested it was likely fine. Ping Plotter shows results over a ten min test and the random drops are more apparent. This is gigabit speed that is sorta new to my area and I feel like it costs me a lot to have, I am very happy with it. Until I want to game online or stay connected to something. I get enough packet loss/jitter to cause a disconnect. Sometimes its short enough that it corrects in game and I just get a rubberband like effect. sometimes its enough to cause the game to kick me. sometimes it just freezes the game and while i am disconnected from their server i can still walk around but not actually do anything in game. interact with characters, cast spells, etc. I would really love some help with this problem! I have tried so many things ruling things out to come to this point. Even as I type this I keep getting notifications at the top right of this website telling my I have 'successfully reconnected'. I need someone to take a look at these links and help to fix this Anyone else that looks will not be able to see these issues with they way they are testing it. I am not sure what else to do but reach out to the forums as home techs and tech support phone calls don't see this problem and assure me everything is fine. but its not fine. not at all. every web site i try to ping for some time shows the same results. 0 issues from my computer to my router the problem begins on the 1st hop after my router. its not consistent this is why the basic level support technician doesn't see it. I will provide any other info I need. I just want to solve this. so far I have paid for a few months of IMO expensive internet and have been unable to use it for the reason i got it.

Hello, As the title says, I have been suffering from severe lag and latency spikes almost constantly when playing online games with Blizzard servers. The time of day doesn't seem to affect it and doing generic router restarts doesn't make a difference. This has been going on for several weeks now and it is becoming unbearable. Any advice on how to fix would be appreciated.5.6KViews1like23CommentsPacket loss, latency on gigablast in Scottsdale, AZ for the last few months
I've been battling issues similar to multiple other recent posts on the forums [1, 2, 3, 4].Since this problem has started, I've replaced the cabling in my house, gotten a new modem and a new router, but the problem has persisted. As of today, I've had four different techs come to my house. Techs 1 and 2 both replaced the connections from my house to my tap. Tech 3 did that too, but also said he added a "boost filter" because of "low transmits" to my modem. Tech 4 replaced connections as well, and then said he "lowered the signal" because it was "too high" at the modem (sounds like he removed the boost filter from tech #3 lol). Today I noticed there is one especially bad host in the tracerts to both a sample Rocket League server and to Google, and several other hosts giving packet loss. Sunday and Monday had very bad packet loss all day, while it cleared late Monday night (9pm-1am). Today there was supposedly an outage in my area, but my Internet access was fine, and in fact had very little packet loss. Lo and behold, as the "outage" was clearing up, the packet loss came back. Attached are several samples from yesterday and today. I chose a smattering of times from yesterday's samples to show that the problem was definitely exacerbated during peak times, but that there is still packet loss in the tracert on Cox's end even outside of peak, which persists even after today's supposed outage was fixed. In addition to this, the last phone tech I spoke to via the Cox Cares (what a BS name) actually remarked that Arizona was the highest reporter of these issues in their personal experience. To me, that's pretty telling. Obviously it's anecdotal, but with my data and the rest of the data from others it seems to me Cox has some serious infrastructure issues that they are actively choosing to avoid dealing with. Lucky for them they have a monopoly here, huh? https://drive.google.com/file/d/1irw5zdTEkkEb5818-UJJBkbLkP6DHzFM/view?usp=sharing https://drive.google.com/file/d/1pkmfPBba58rBVsLE1dvU53BGUTjvKtNN/view?usp=sharing https://drive.google.com/file/d/1gHbb7vwUXIT2FXpFvoeNbbpUsogvPwT7/view?usp=sharing https://drive.google.com/file/d/1RmCGIvrtx1Sc1Q7w0yU7b6gbJP_ggy3G/view?usp=sharing https://drive.google.com/file/d/1TmK8voj4KXR4li6N7XahocB4uA6HC5m1/view?usp=sharing https://drive.google.com/file/d/1bLOWFfg9vnDwZ6PAbCz1G_406JJmSeXe/view?usp=sharing https://drive.google.com/file/d/1LhWZxlJoREkhb7Fji6HAZ0X6EIC6J55d/view?usp=sharing https://drive.google.com/file/d/19YF_sdIIG8sAyVAQorc_fYIj0X6cjlHO/view?usp=sharing [1]Gaming and warzone/CoD in general packet burst - Internet - Internet Forum - Cox Support Forums [2]Noisy node issues - Speed drops until reset - Internet - Internet Forum - Cox Support Forums [3]Terrible packet loss and jitter. - Internet - Internet Forum - Cox Support Forums [4]Another packet loss and ping spike issue - Internet - Internet Forum - Cox Support Forums5.5KViews1like25CommentsGaming and warzone/CoD in general packet burst
I've done everything I could. Replaced the modem, gotten a separate router with SQM/QoS capabilities, called a tech out, there have been no answers. I pay $120 on my bill every month for 500mbs and nothing to show for it. It's the most frustrating thing to have around 30-50ms ping but still have lag stutters, packet burst symbol pop up, and faulty hit registration due to speed spikes. Who else is feeling this? I want to back to 150, but its even worst! Can't even play a game due to the heavy lag. Is there a fix? Cause everyone at cox seems to be dismissive and gives no real answers or solutions.5.4KViews1like4CommentsCox throttling speeds to gaming servers? I think so.
So I've just had it with Cox and their seemingly dishonest practice of blaming everything on the customer... I just got the 300mbps service in Las Vegas, and suspiciously get 500% increases in ping to gaming services as opposed to standard browsing/streaming service. I've validated everything is good to go on my end, and spent an hour or more being treated like a fool with Cox "technical support" people who don't even know what ping or traceroute are. As a background I've worked in IT for 15+ years and manage large load balanced networks like this for a living... Either there is an immense amount of ineptitude and apathy going on, or they're trying to push gamers to spend more money. My modem is a DOCSIS 3.1 enabled modem. My router is a gigabit router. I'm wired into the router with CAT6 cable, directly. My connection to the COX gateway is fast, and fine. The issue is the Cox internal routing. In this case, I'm going to use League of Legends for an example since they post their server IPs publicly. All I need to do to show where the breakdown is occurring is run a simple tracert. It's clear that I'm getting solid ping to Cox's gateway - langbprj01-ae1.rd.la.cox.net [68.1.1.13] - but they're choosing to route gaming traffic specifically through some kind of WAF, concentrator, or other type of internal network device which is throttling all traffic to 60-70ms (at lowest) The glaring technical evidence: Tracing route to 104.160.131.3 over a maximum of 30 hops 1 <1 ms <1 ms <1 ms 192.168.1.1 2 9 ms 8 ms 7 ms 10.67.0.1 3 8 ms 8 ms 7 ms 100.127.4.164 4 11 ms 7 ms 11 ms 100.120.102.24 5 15 ms 16 ms 12 ms langbprj01-ae1.rd.la.cox.net [68.1.1.13] 6 60 ms 61 ms 61 ms 72.215.224.162 <---- the offending Cox IP. 7 61 ms 67 ms 65 ms 104.160.152.223 8 62 ms 61 ms 60 ms 104.160.152.227 9 67 ms 70 ms 70 ms 104.160.159.100 10 68 ms 67 ms 68 ms 104.160.131.3 So why are they throttling gaming speeds to 60-70ms? It doesn't really make sense until you realize they've just started marketing their "Cox Elite Gaming" service to unlock higher speeds for a premium monthly rate. The only problem? I CAN'T EVEN BUY THEIR EXTRA SERVICE IN MY AREA. Come on! If you're going to scam me into buying a premium service, at least offer the option to buy it! My only option has been to reduce my service to the 150mgps service (why bother with bandwidth if it's slow), and subscribe to Haste for a slight ping boost to try and compensate. Note - COX - you're losing money here. In the end I'm just getting screwed, and Cox is showing how dishonest they are. If they could explain exactly what that IP is and why they refuse to address it internally, maybe it will matter. Until then I'll be planning my exit ASAP.9.4KViews1like11Comments
