Interesting, odd, and extremely annoying pattern specific internet slow down occurring at 6/7pm every day [San Diego]
PSA: I understand how to code in 4 different programming languages and understand networking at a high level. Cheesy to write this, but refrain from providing basic, simpleton-user information. I for one would like to say I haven't had much issues with cox in the last 3 years. Now, ever since the insane lightning storm in San Diego on Oct. 4 my internet has been severely slowing to an unusable level oddly enough at 6pm every single day. Mind you, I have top of the line equipment I spend hundreds on, all the way down to CAT8 cables. Now, I did diagnosing of all the components of my network and saw that all pieces of equipment functioned. What it is is the service itself is oddly enough throttling to very slow speeds at 6pm. I say this as the tech support mentioned to me to replace the modem to test the connection, and I obliged. Even before getting the modem, I knew my top of the line Motorola was not the problem because funnily enough the issue is stuck to an odd pattern. Today, I got the cox authorized PW7 which features a docsis 3.1 modem and router. Not going to lie, the speeds were amazing on it after I hooked it up and tested at 1pm[remember this time]. Sure enough, even with the new modem, the insane slow down occurred. Now, a tech has been specifically appointed to come at 7pm to catch this weird slow down. Pattern: 10am- 6/7 pm the internet is as perfect as you can get. I have gigblast and get 5 ping 950 down and 37 up. Then, sure enough, as 6/7pm rolls around, the download is cut in half and the upload is decreased from 37 to literally .9 mbps. You can even tell during the day as the websites and other services load instantly and then after 6pm I can't even load a website or do anything. TLDR:Subscriber's equipment is not at fault, even used cox's new modem to test, and a pattern specific slow down of the internet has been occurring at 6pm every single day since Oct. 4th. The level of degradation: download cut by 2/3s and the upload cut from 37 to literally .9 mbps. This all amounts to an unusable connection. If the new cox modem was affected too, we can deduce the old modem was never the problem and the true issue is intermittent occurring at 6pm on. I already have spoken to a supervisor of which has made sure to send a tech at 7pm, which should be a late enough time for the issue to be visible. I am merely writing this to reach out to all and share what an interesting and funny problem this is. Also, I have a weeks worth of speedtests documenting the odd degradation pattern. I also would like to have the first tech visit a day ago waived as this is truly an external problem. I find it laughable when the field techs use their devices before 6pm, of which is when perfect speeds do occur, and claim nothing to be the problem when you describe the complexity of the issue occurring past 6pm. One word: intermittent. I will upload an update on Wed. after the tech shows at 7pm to see what might be the issue. Also, I might be reaching but this issue was only noticeable after the lightning storm in San Diego on Oct. 4th. A literal lightning bolt hit 10 ft from my apartment and rattled everything; I wonder if this has anything to do with this odd issue. Also, for the last 3 years no slowdown has ever occurred, even during peak usage times of 7-11 pm.
Post Hurricane Ida performance
***Update since services came back online 3 weeks after Ida*** My speeds here in metairie, LA. Were consistently 500 my + for months before hurricane ida. After hurricane hit, speeds came back but were slow, leggy and intermittent were getting disconnected. However. Speeds have improved dramatically but still not back to 500MB. In the mornings, I approach 250-300, but after 8am- ish, speeds drop back down to 30mb until late night. I believe cox cable is slowly repairing and fixing the speed issues in our community but it will take time. I have already reset modem and had a technician visit to check that the tap outside the house is not getting the right signal//speed. At least it's not my house and confirmed that it's on cox cables side Thanks to this forum for letting us express and discuss concerns.
Unusably Slow Ethernet Speed from Panoramic Gateway with Gigablast
Hello, I just finished installing Gigblast wifi today, and my wireless internet works fine. However, when trying to connect the included ethernet cable to my laptop, my laptop says it connects successfully with internet access, but it is so slow that I can not load any pages. I have tried many possible fixes, such as flushing my DNS cache, re-installing my ethernet driver on my computer, restarting the gateway, and disabling my firewall, but nothing has worked so far. Windows network status says that I am connected to the internet. For a full list of things I've tried (probably not exhaustive either)... Restarting computer Restarting/rebooting gateway Setting TCP/IPv4 properties to automatically obtain IP/DNS server ipconfig /flushdns ipconfig /release ipconfig /renew netsh winsock reset Disable Windows firewall Disable firewall in Cox gateway settings LAN Ethernet link status is active in Cox gateway settings Try different ethernet cables Try both ethernet ports Disabling/re-enabling ethernet network adapter Check/uncheck TCP/IPv6 in ethernet properties Disconnect from wireless network Ran TCP Optimizer Checked hosts file (nothing in there) Get-NetAdapter in PowerShell shows link speed of 1 Gbps Disable/enable "Automatically detect settings" in Windows proxy settings Windows network reset Clear cache in web browser Tried multiple browsers with all extensions disabled Any other suggestions would be appreciated. Thank you.
Not Getting Gigablast Speeds
I recently upgraded my service and I am only getting 300-600 mbps and I am averaging around 400 mbps. I have a CM1100 DOCIS 3.1 modem. I have had multiple tech's out to fix issues on their end (terminations are curb and amplifier in node) and I have only seen a small improvement from what I was getting prior to the fixes, 200-500 mbps. Here my modem connection stats are below.

Upload speed has been below 0.10 mbps recently if not lower. My download speeds have been perfectly fine. I cant figure out the problem and i cant find any other forum post like this that has been answered ,But it seems like a lot of people are having this issue. Speed Test Results
Arris SB8200 Firmware Update / Download Speed Issue
Hello - I activated a new SB8200 today with Cox. In reviewing the firmware, it appears that the modem does not have the latest firmware update applied. That said, I also understand that Cox controls which firmware is actually applied to the device once it is on their network. So, I'm looking for the answer to a couple of quesitons: What the the latest approved firmware version for the Arris SB8200 modem on Cox's network? Mine is runningAB01.01.009.27_081619_183.0A.NSH If a more recent firmware has been approved, how long does my modem have to be online before it will pick up the latest firmware and apply it? I bought this new modem (along with a brand new TP-Link AX6000 router) in an attempt to improve my download speed. However, I'm finding that the speed is not improved any from the previous setup (which was the Cox-provided Panoramic WiFi modem). I am a Gigablast customer and this modem is listed as "Gigablast compatible". I'm getting around 200-300Mbps down on average. In reviewing the modem's event log, I also notice several "SYNC Timing Synchronization failure - Loss of Sync" messages. Not sure if that's relevant or not to this issue.

High packet loss, extremely slow speeds, and modem errors
Hello! As of a few days ago after I have recently purchased an aftermarket modem (Netgear cm600) I have noticed that at during certain times of the day the connection of the internet will just drop incredibly low and will pertain for quite a few hours. I have always had high ping on one game abnormally named League of Legends, where I usually sit at 78-85 ping which instead should be 50-55 ping. That's not really the issue as of right now though, as I end up having about 92 ping on the game whenever this happens but on top of that I end up dealing with 15-25% packet loss which is extremely detrimental and makes the game feel like I'm playing on 300 ping. From just general research on the internet of where people have had similar problems, I've seen that sometimes the registration processes just haven't been fully done which would be generally possible since this router has just been registered recently. There is also the possibility that the line near my house is faulty and needs to be updated, but other than that I guess that would be up to you guys to figure out. If I could nip this in the butt and to also possibly figure out why I am not getting the ping I should be getting in my video games I would greatly appreciate that. I'd like to for sure figure out why I am dealing with this packet loss though as this is extremely detrimental. I can't surf the internet without pages taking a long time to load and my games feel torturous. Here are my modem logs ever since I have received it. 2020-05-11, 13:08:25 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-11, 11:48:31 Warning (5) Unicast DSID PSN startup error 2020-05-11, 11:46:05 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-11, 11:37:30 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-11, 11:36:25 Critical (3) No Maintenance Broadcasts for Ranging opportunities received - T2 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-11, 11:36:11 Notice (6) TLV-11 - unrecognized OID;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-10, 12:50:01 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-06, 23:10:55 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-05, 16:04:53 Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-04, 14:12:10 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-04, 14:10:12 Critical (3) Resetting the cable modem due to docsDevResetNow 2020-05-04, 14:09:39 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2020-05-04, 14:06:55 Critical (3) Resetting the cable modem due to docsDevResetNow 2020-05-03, 16:56:12 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; 2019-06-02, 15:16:37 Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.1;CM-VER=3.0; Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Warning (5) DHCP WARNING - Non-critical field invalid in response ;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Notice (6) Honoring MDD; IP provisioning mode = IPv4 Time Not Established Critical (3) Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Critical (3) No Ranging Response received - T3 time-out;CM-MAC=redacted;CMTS-MAC=redacted;CM-QOS=1.0;CM-VER=3.0; Time Not Established Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;CM-MAC=redacted;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.0;CM-VER=3.0;
COVID-19, Slow Speeds, and Why You Are Paying Full Price for Them!
COVID-19 is clearly slowing down many of Cox’s servers due to the increase of Residential use across the nation. Many more people are at home and needing to use the internet for very demanding virtual tasks to replace going to work. Gaming has also increased substantially with schools and colleges around the nation closing. This is throttling your internet speeds drastically as we speak! Why are we still paying full price for our service then? Follow this link to submit an informal complaint to the FCC for Cox’s unwillingness to reimburse their customers for paying for full price speeds, while realistically receiving fractions of the speed! https://consumercomplaints.fcc.gov/hc/en-us For example I have the Ultimate package at 300 mbps, and currently I am receiving anywhere from 5 kbps to 20 mbps!
