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?Solved16KViews1like18CommentsHow to reset gateway password
I recently upgraded my Cox router and have forgotten the password I changed it to from the default "password" when I set it up. I've looked through the Cox Support articles and have searched everywhere but somehow no one, in the last 20 years, has forgotten it. I'd rather take a bullet than have to chat with a representative so, please, if anyone knows how to do this and can tell me I will be forever grateful.9.9KViews0likes2Commentsis it possible to change the wifi channel on my panoramic wifi to one that is less crowded?
Hello, I'm reaching out to ask how I can change the wifi channel used by my panoramic gateway/router. I have been having a lot of internet stuttering and lag recently. I thought the problem might resolve itself after the scheduled outage for system work on 3/15/2022. it didn't, so i changed my plan to a higher tier thinking there were more neighbors paying more, and i was getting slower speeds to keep bandwidth available. that didn't change anything either. After doing more homework I was led to look at the channel my hardware uses for wifi. This seems like a likely cause for the problem. I am on a channel with 15 other users that show a strong connection. there are 5ghz that are unused and available. i found that i can get to an older java interface through a browser by pointing it to the gateway, but that app says channels are automaticallycontrolled. any advice would be appreciated. regards, chris9.7KViews0likes9CommentsUltimate 500 modems
Just confused at why modems rated higher than 500mbps are stuck at the Ultimate Classic tier, which to my understanding is 300mbps and not even offered anymore (grandfathered plan) - If the modem is rated for 680mbps, what's the technical limitation as to why it can't support 500mbps? - The current tiers go from 150 mbps service to 500 mbps service. If you don't even offer Ultimate Classic service anymore, why is it listed on the Cox compatiblemodem pagehttps://www.cox.com/residential/support/cox-certified-cable-modems.html8.4KViews0likes15CommentsMODEM firmware
Why is it impossible to get cox to provide firmware updates to modems? The Arris SB8200 is listed as a GigaBlast modem. Many chats later and I had one tech tell me that it "would be very illegal for Cox to control the firmware on the MODEM". Obviously, that is not the case because the cable provider is responsible for controlling the firmware that is at the gateway. I don't even have the ability to do that as a consumer. So how do I get it updated>??5.5KViews0likes4CommentsRouter has no connection after a power outage?
Hello, just yesterday morning/afternoon a storm knocked my power out momentarily, but the router hasn’t seemed to recover yet. I was wondering if I could get the status of my router checked and possibly remotely reset? Manually resetting it at home hasn’t seemed to work, and I know when someone did it remotely when I asked on here, it worked just fine afterwards. I hope my router is alright.4.3KViews0likes5CommentsDoes Cox support Link Aggregation?
Hi So on my Arris SB8200, there is a setting for Link Aggregation. My router also supports it and so does my computer. But Cox states on their website only one of the ethernet ports on the modem can be used. Even with the firmware does Cox support LAG?4.2KViews0likes2CommentsGET THE INTERNET SPEED YOU DESERVE WITH A MODEM UPGRADE ON US
So I received a letter from cox informing me that my modem needed upgrading and that COX would provide a modem at no additional cost and it will on them and that they look forward to providing the modem soon. despite 30 minutes on the phone with customer service I am still without an upgrade. ANyone else had this issue. Shame on COX for their fraudulent misrepresentation and lying letter.Solved4.2KViews0likes7CommentsArris SB8200 Docsis 3.1 GigaBlast No Blue Lights Up or Down
Called Cox for new internet options. Told me I was grandfathered in at 150. Quoted me 300 and Giga. Call ended. I had a Netgear 3.0 modem / router combo that worked fine. I buy a 3.0 modem and a mesh router to increase my WIFI area. I try to get it calibrated only to find out I have a work order for GigaBlast speeds and my 3.0 equipment is unusable. So as a patient person I go and swap my 3.0 for a 3.1 modem costing me more money. I call to get the 3.1 calibrated by Cox and it shows all green lights 3.0, no blue lights for Arris SB8200 Docsis 3.1 GigaBlast No Blue Lights Up or Down. Speeds are 250 down and 20 up and that is before and after a modem factory reset with ONLY my laptop plugged in. Tried with a desktop as well with the same result. - Called and asked was GiagBlast and Docsis 3.1 avilable in my area and told it was - Forced to GigaBlast without request and told I can't return to my original speed - Asked me to upgrade my equipment to take advantage of GigaBlast but when equipment is installed it I only get 3.0 and low speeds - Called from 10am to Midnight and text chat too. After dealing with 6 different people and a whole day wasted I still got nowhere - Best of all I was told no work could be done while there was an "outage" in my area. One that lasted from 2pm to 7pm, and then another that started at 12am forecast to end at 6am. Anybody else have these issues and if so how were they resolved??? - Do yourself a favor and DO NOT, I repeat DO NOT engage in the text chat option from your phone. A waste of time and resources!!!!
