Packet Loss in the Evening (7PM-2AM)
I have been experiencing intermittent packet loss (particularlyat night) over the last few months with associated event log errors on my cable modem (MB8600). Screenshots are attached. PingPlotter capture over Ethernet: Update 2020-09-03 — Packet loss starts at ~19:00 EDT, or start of "internet rush hour", 19:00PM - 23:00PM.86KViews0likes5Comments
Slow Speeds with Netgear R7000 Router - How We Fixed It - SOLVED
This is a post about slow internet speeds with the Netgear R7000 router and how we solved the problem.If you want to skip directly to our fix, goto the fourth paragraph from the bottom of the post.If youwant the background first, keep reading. Like others, we've been having slow internet download speed issues with our R7000 router. These slow speeds are when we are connected by cable to the router with the wifi off on the computer and the router or if connected by wifi to the router - it doesn't matter. Our internet connection is the Ultimate package rated at 300Mbps/30Mbps download/upload. When connecting through the router we would be lucky to get 120-160Mbps download but always 30Mbps up. When connecting directly through the cable modem (Motorola MB8600) we usually get our rated download speed and above. All speed test numbers have been tested using not only the speed test software housed at Cox, but also speed test sites on the internet. All speed tests confirm each other as they are within 10% of each other with, of course, the ISP's test showing the fastest. Regardless, the R7000 router always showed 120-160 down (sometimes even half that at times). There would naturally be slightly slower speeds during congested times during the evening, but the R7000 would always be about 50% slower than if we were connected directly through the modem, bypassing the router. Before getting to what we did with the router, here is everything else that was done to isolate any other potential problems. Cox came out to the house multiple times. Network cables from the computer to the router and router to the modem were fine, but we replaced them with brand new CAT-7 cables anyway. Interior house coax cabling was fine and barrel connector were fine but connector replaced anyway. From the house to the tap, the cabling was fine. The tap checked out OK, but since it was old they replaced it anyway. The cabling from the tap to the post where cabling comes out of the street was fine, but they rebuilt the post anyway. The cabling in the street had one section that indicated some slight signal loss, so they replaced the cabling in the street. Back in the house, their test equipment was attached to the line ahead of our modem and regularly showed 315-330Mbs down and 31Mbps up. They reprovisioned our line at the central office, installed their modem on the coax, directly attached their modem to our computer and regularly got 300 or above on multiple occassions. They reprovisioned the line again,installed our modem on the coax, directly attached our modem to our computer and regularly got 300 or above on multiple occassions. Computer settings were checked to make sure everything was configured correctly and all unnecesary computer processes were stopped to make sure nothing was interfering. So, everything is OK on the ISP side and also with the computer and its cables. After making sure everything else was OK, we shut everything off, connected the computer back to the router and the router back to the modem, let the modem boot up completely, then let the router boot up completely, then let the computer boot up completely. After making sure all unnecesary processes were stopped, new speed tests were run showing slow 120-160 download speeds. Multiple tests over the past month connected to the router, whether by direct cable with wifi off on the computer and router, or whether connected by wifi consistently showed the slower speeds from the ISP's speed test and multiple internet speed test sites. And multiple tests while bypassing the router and being directly connected to the modem regularly showed 300-350. So the router was definitely the issue. Have we reset the router back to factory defaults? Yes. Have we been sure to download and install the latest firmware when it came out? Always - and there is where the problem is. We dutifully upgraded all the firmware releases up through the most current v1.09.18 (as of January, 2018). After reading others' posts, a number of them have talked about downgrading the firmware. Some have said v1.09.06 worked for them (but their rated line speed was, if I recall, much less than our 300/30). Others have said they have downgraded to v1.03.24 that had solved their problems (in fact, one of those people had a line rated at 400/40). Still others said v1.07.12 solved their problem. Hmm, was this the answer? After looking through our old speed test results from October, 2017, we noticed that when we upgraded our line in October from Premier 100/15 to Ultimate 300/30, we also upgraded our R7000 firmware from the 1.07.xx series to the 1.09.xx series - and that 's when our problems began. All along we thought the issue came from the ISP, thinking they either had equipment problems or that they had mis-provisioned our line when we switched to the faster plan. It turns out it was the firmware on the R7000 router. FINALLY - HERE'S THE FIX.We factory reset the router once again, downloaded and installed the v1.07.12 firmware, then again factory reset the router, direct connected to the router before rebuilding all our old settings, kept wifi turned off - and now we are regularly getting 300-350Mbps download from the router. After rebuilding all our old settings, turning wifi back on and still staying connected directly to the router, we are still getting 300-350 downloads. Removing the direct cable connection to the router and using the wifi from the computer to the router, we are regularly getting +/- 300Mbps downloads (of course depending on how close we are to the router). So that's the simple fix. I suspect there is something lurking in the 1.09.xx series firmware that is not allowing the router to efficiently handle higher rated line speeds (if you are at 150Mbps rated download or below, I'm guessing you are OK). Some people might say our settings weren't correct in the router when using the v1.09.xx firmware releases. I don't think that's the case since we tried everything AND we also factory reset the router while still using the v1.09.18 firmware. Hope this helps. This post was written January 10, 2018. The most recent firmware as of this date was v1.09.18, which caused us to have slow download speeds on the R7000 (much slower than our 300/30 line). If you're reading this after January, 2018, and you have slow speed issues with the router, and if the most current firmware is in the 1.09.xx series, I would suggest downgrading back to v1.07.12. UPDATE as of January 22, 2018: This fix has continued to work reliably. I'm consistently getting download speeds in upper 300's to lower 400's - either connected directly to the router or using wifi.21KViews0likes2Comments
Upload Problems
Hi, So I've been having problems with my upload for awhile now. I have the Ultimate package which is 300 down 30 up, the problem is my upload is never consistent and this is a problem because I live stream. At first I never got anything above 2-3Mbps so I called cox and they sent a tech out and the tech said there was a lot of problems in the box on the street including a trap. He said he fixed the issues in the box andthat if I was still having problems to call them back out to run a new line from the outside of my house to the inside as the line that runs through the walls was old, he also told me the modem I was renting from Cox was known to have problems. So after he left my uploads were about the same but I wasn't getting the packet loss that I was getting before. I called Cox and scheduled a tech to come out and replace the line i also starting doing research on modems and found out about the Puma 6 problems so i ordered the Netgear CM600 which has the Broadcom chipset. Now here's where it's starts to get weird, after I set up the new modem and called Cox to activate it I ran some speed test and my results were awesome I was getting like 17-25Mbps on my upload, I was really happy and I thought the issue was fixed so I called up Cox to cancel the tech. About 2 hours later Inoticed I was starting to drop frames so I ran some upload test and my upload speed was dropping lower and lower after each test until it back down to 3-6Mbps so I rescheduledthe tech to come out but the following day when I woke up speeds were back up to 17-25 Mbps, then they dropped again. The tech came out replaced the lines and the speed went back up for about 5-6 hours but then they dropped again. I don't know what the problem but my brain is about to explode. I need to fix w/e is causing this, I cant stream with upload that's all over the place and never consistent. If anyone has any ideas or suggestions I would really appreciate it. I run all my speed test on Testmy.net and speedof.me and use the Twitch Bandwidth tool for connections quality. I'm also not wireless I'm hardwired.19KViews0likes1CommentTo all the people that have been experiencing low upload speeds, I have had a break through.

Personally I have found that non cox servers give me better results. I hope this has helped me. if you have any questions or concerns drop a comment.17KViews0likes0Comments
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?Solved16KViews1like18Comments
Extreme Packet Loss Recently
Me, and many others have been receiving excessive packet loss in Fortnite servers located in US-West which I believe is hosted on Amazon EC2. I've contacted Gigablast multiple times and they are of no help. I've tried two different modems and two different computers and problem exists. There are tones of other people experiencing this same issue. There are also issues people are having regarding packet loss on Netflix services (which are also hosted on Amazon?) . So I'm not sure if something routing related has happened with Cox & Amazon EC2 West Here's a forum post with many people in my location with this issue (https://www.epicgames.com/fortnite/forums/bug-reports/battle-royale-aa/681327-fortnite-packet-loss-and-ping-lag-spikes-as-of-recently-9-04-2018) A recap of it all is: - This is a recent issue in NA-West on Cox Communications (mostly Southern CA / San Diego) - If we switch to NA-East, packet loss goes away (but high pings) - It's intermittent, meaning, most games have excessive packet loss, but sometimes some servers give 0. - It's not hardware related. I tested two computers, two modems (directly connected) and the problem still exists. - Last night around 11 PM PST, I was consistently getting lower to no packet loss, so the issue seems to be 5pm-10/11pm PST. - Internet speed tests show 1gbps down / 30mbps up, low Fortnite ping, but 30-50% packet loss constantly. I ran packet tests for 20 minutes while I was experiencing this issue on ~20 other IP/Websites and received no packet loss on any of them (besides google.com). Please look into this and help the community! Thanks12KViews0likes23CommentsHigh Ping and Packet Loss in Gaming
In games such as CSGO, Rainbow Six Siege, Fortnite, and PUBG, I have really high ping and packetloss. Sometimes the ping is great and the packet loss is bad, but other times the ping is horrible and so is packet loss. Sometimes my ping ranges from 10ms - 70ms. Othertimes it ranges from 60ms - 300ms. Packetloss sometimes ranges from 0% - 10%, but other times it ranges from 10% - 100%. Sometimes I can't even watch videos in 720p. I contacted the ISP once and they sent a technician out, but he said that nothing could be fixed. They swapped out for another modem and nothing. He said it can't be fixed, however I don't believe that because we shouldn't be having poor internet like this.11KViews1like1Comment
Bridge mode not giving out IP address?
Put myPanoramic Wifi Gateway into bridge mode and conencted it to my ASUS router but its not handing out an IP address. I tried to chat with Ccox support online and they seemed clueless. Called into support and they didnt understand what I was trying to do and were not aware of bridge mode. After talking to a few people I finally spoke with someone who mentioned I had a static IP attached to myPanoramic Wifi Gateway? I didnt request a static IP and was not even aware residential users could get a static IP. He said he removed the static IP and rebooted thePanoramic Wifi Gateway but it was still not working. I finally decided to clone the MAC address of thePanoramic Wifi Gateway on the ASUS router and things started to work.None of this makes sense to me.11KViews0likes3CommentsSlow Upload Speeds; Trying to Stream on Twitch
So recently I have been trying to stream on Twitch.tv, and even thoughwe paying for the Ultimate Internet package, which includes 30mbps upload, I am only able to stream at 3500 bitrateand this still doesn't guarantee a good quality stream without dropped frames. I would also like to mention that even though we are paying for this service, I am getting an average of about 20-24mbps upload, with it very rarely reaching 30mbps. I called about this a week ago I had two techs come out so far. One came out Monday the 17th and another came out today at around noon. The first tech said everything should be fixed by Friday, but I have performed multiple speed tests since then and I have yet to see speeds remotely close to 30mbps aside from a couple trials. (see attached image) He also put in a ticket for someone from Cox's maintenance team to come and see if there were any issues on the line outside my house, and from what I have been told, everything has been resolved yet I am still experiencing less than expected upload speeds. I also have performed multiple Twitch Bandwidth tests toverify that there is an issue with my upload speed, and sure enough I get mediocre bandwidth results along with very low quality connections to servers that are close to me. (see attached image) Not sure what to do at this point because it seems like getting a tech out here for the third time would be nothing but a nuisance to them, since all they do is come here and tell me they can't do anything about it and that they will forward the issue. Hopefully someone on here can provide me with some help. Thanks11KViews0likes17Comments
