Arris SB8200 Questions
Today I upgraded to the Arris SB8200 modem and when I have the coax cable plugged into the modem I cannot access the web gui using the standard http://192.168.100.1/. Also I noticed that all my lights are green and none are blue for bonded channel. How long does it take for the channels to bond and why can I not access the gui when connected to the coax network?658Views0likes13Comments
SB8200 and other Arris Event Log Page Problems After July 2023 Cox Firmware Push
After Cox TB01.03.001.16_091322_212.0A firmware push, the Event Logs page shows an odd text message pasted over the upper left corner of Event Log page and NO Event Log entries are downloaded. The text says: Confirm Settings Do You Want to Continue? Disable and Continue Cancel But none of those supposed links is active for clicking. Anyone else seeing this? I can't find an easy way to post the screen capture.489Views0likes3Comments
SB8200 lost upstream bonded channels - power too low
For about one year now, I've had an Arris SB8200 cablemodem and Cox 300Mbps Internet tier, and this has worked esssentially flawlessly in that time. I've had Cox Internet even longer with very few issues - until about two days ago. I noticed decreased download speeds, and when I logged into my account, I was notified that an "issue" in my area was detected, and I assumed my speed issue would be resolved when the issue was solved. About two hours later, the issue was clear, but my Internet speeds were still decidedly abnormal. I then noticed that the middle-two lights on the front panel of the cablemodem indicated the *downstream* connection was DOCSIS 3.1 (bonded downstream), colored blue, but the *upstream* light was now *green*, indicating only DOCSIS 3.0. This is a change from the previous behavior in which both up and down lights were bonded (blue). That was two days ago. The problem has persisted, across multiple reboots of my cablemodem, and reboots of the firewall appliance that receives the Ethernet out from the cablemodem. I contacted Cox and they said the signal looked clear, but they agreed that my struggle to reach 200Mbps (usually topping out around 170-190) is not consistent with the 300Mbps service tier. They went so far as to re-provision the modem, all to no avail. I took a look at my cablemodem serivce page, and it shows that the upstream channels hover between 39.0 and 42 dBmV. I found that Arris states the required upstream signal must be between 45-55 dBmV. A bit of Googling has revealed a bit of warfare normally has to be undertaken to get Cox to increase power to the upstream channels, which is precisely what the Arris tech support rep told me when I reached out to them for assistance (cablemodem is only one year old and under warranty). He flatly stated the ISP must increase channel strength. Excerpt of my upstream channel status listed below: 1 1 Locked SC-QAM Upstream 17400000 Hz 6400000 Hz 42.0 dBmV 2 2 Locked SC-QAM Upstream 23900000 Hz 6400000 Hz 42.0 dBmV 3 3 Locked SC-QAM Upstream 30300000 Hz 6400000 Hz 41.0 dBmV 4 4 Locked SC-QAM Upstream 36700000 Hz 6400000 Hz 41.0 dBmV 5 6 Locked SC-QAM Upstream 12600000 Hz 3200000 Hz 39.0 dBmV I traced the line all the way back to the Cox input, eliminating an intermediate cable in the attic, and directly attached the Cox coax to the cablemodem and powered it up - no difference - bonded down, unbonded up. This means the signal to the modem from Cox is too low. But if I know from research Arris says Cox has to increase power, but Cox will refuse, what on earth do I do? Go out and drop another $200 on a new/different cablemodem? Any suggestions appreciated. -sd5.6KViews0likes25Comments
Cautionary tale before taking a free DOCSIS 3.1 modem upgrade
I work in IT and my client called because Cox sent them a new Arris CM8200 cable modem. I asked if they upgraded to a higher speed plan that would require it, but they hadn't made any changes to their services with Cox. It seemed odd, but since it was provided at no charge and the modem was essentially an updated version of their current SB6183 modem we went ahead and installed it. I explained the differences between DOCSIS 3.0 and 3.1 to my client and that 3.1 is more efficient with how it uses the available spectrum on the cable lines. (QAM256 vs. QAM 4096) Now the bad part.... After upgrading, they started to notice problems with call quality on their VoIP phones. I wasn't made aware of it initially as they contacted the VoIP vendor for help. After being made aware, I ran some ping tests to see if there was any obvious problems. Sure enough, pinging the gateway on the Cox side along with Google and Cloudflare DNS showed packet loss. We contacted tech support to see what could be done about it. We were informed that the node we were using was noisy, overloaded and experiencing capacity problems. Since speed was not a factor and reliability was more important we decided we should try to switch back to the old cable modem. With the problematic and noisy node we were on, running the older, but less efficient QAM256 modem might help alleviate their problems. After all, they hadn't experienced any problems before installing the newer modem. Also, the previous SB6183 is still a modem on the Cox business compatibility list. Cox Business Certified Gateways and Modems | Cox Business So we called tech support to swap the old modem back, but we were informed that wasn't possible. I was told upgrading to DOCSIS 3.1 was a one way street and we could not reinstall our old modem. Installing the DOCSIS 3.1 modem offered little benefit to my client, but benefited Cox by helping them avoid a costly node split. So now they are stuck with poor quality internet and have no other option other than to repeatedly call tech support and complain. After more than a dozen phone calls with no resolution I was referred to the customer retention department. This is an unacceptable situation to put a business in. So beware that Cox may send your a new modem, but make sure that you will benefit from it before installing. There is no going back once you've upgraded, even if it results in a connection of worse quality.3.2KViews0likes3Comments
Intermittent disconnects with new service, slow speeds overall - SB8200 in Omaha area
I started service 2 weeks ago when we moved into my new house in an Omaha suburb. Previous owner had Cox (looked like a business modem, but was ~12 years old). I'm paying for 500Mb package but we rarely get that. I activated service over the phone and installed my own Arris SB8200 (bought just for Docsis 3.1 for this new package, my old modem was Docsis 3.0) directly on the main line, after removing all the splitters inside because I don't use cable TV. It activated fine, the tech I spoke to on the phone didn't see issues and a quick speed test showed speeds close enough to 500, so I connected a router I bought a year ago (Netgear Nighthawk AC2300) and updated the SSID/password and started connecting my devices to wifi. Over the next few days, we had intermittent disconnects but didn't notice them much because we were moving furniture and setting things up in the new house. When I started working from home with my laptop, I noticed severe disconnects during Zoom calls but streaming video on TV was fine (later found out it was buffering far enough ahead to continue through the outage, most of them last 3 minutes or less). Fast forward to this week, we're getting ~8 disconnects per day ranging from 2-7 minutes long, some as often as 15 minutes apart. I see 32 channels on my modem status page, plus channel 159. Channel 159 has millions of correctable errors (which I understand is not a problem) but Channel 22 has hundreds of thousands of uncorrectables per day. I'm also seeing DRW errors in my modem's log and sometimes sync errors, some of them coincide with the outages but sometimes do not. Speed tests via the router firmware have also dropped a great deal, yesterday as I investigated, speedtest.net showed download speed of 150Mbps, far lower than the 400+ I was seeing at activation time. Ping and jitter consistently test much lower than my previous service in another city, but the inconsistency caused by these disconnections has made the overall performance much worse. I have called Cox about this twice and text-messaged Support, but they throw their hands up and say it has to be my equipment because "everything has green checkmarks except OFBM status" and when I ask to be escalated to someone who can look at my logs or status with me, they try to sell me Complete Care or convince me to pay to send a tech out (who will likely throw hands in the air too and want me to pay for something that's not my fault). What else can I do? Is there a secret to getting help and resolution from Cox? I may have just gotten bad level 1 agents but I'm not getting the service I'm paying for.

Internet Speed Capped to 100 Mbps
I have been a Cox customer for about 10 months and within the last month I moved and transferred my service. Every since then, I have been unable to obtain download speeds higher then 100 Mbps. I have been paying for Gigablast the entire time and I also pay for unlimited data. I have contacted multiple support representatives and I have not gotten a clear answer as to why this is happening. Most tell me that it is my equipment that is causing the issue and that I should contact the manufacturer. They have even stated that if my equipment wasn't the issue, then there wasn't anything else Cox could or would do for me on this issue. I am using an Arris SB 8200 that is just about 11 months old and a new Amplifi Mesh WiFi system that is less then 2 months old, all of which where working just fine until I moved into this new place. But never the less I have contacted both of them and they can not find anything wrong with their equipment. With that in mind, I reset both to factory settings twice in the last month and I still am not able to download anything faster then 100 Mbps. The last service representative I spoke with scheduled a technician to come out to my home to attempt to resolve the issue. I am skeptical that this will work because when I asked what the tech will do during the appointment, the representative said " hopefully they can fix it, if not they will just have to run it up the ladder and escalate it." They said they had the same problem at there home and that the technician could not resolve it so they have just been dealing with it. So now I will just get to wait and see what happens on Thursday. Hopefully someone can offer up a solution a solution other just then dealing with it, or down-grading my internet package.4.6KViews0likes13CommentsArris 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 running AB01.01.009.27_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.

That said, I'd be happy to consistently get between 500-700 down. Am I crazy to have those types of expectations considering what I pay for this service? Thanks in advance for all the help!

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?4.4KViews0likes2Comments
Arris Surfboard CM8200/ SB8200 vs Motorola MB8600
Can anyone confirm that the CM8200 and SB8200 are identical with the exception of the CM beeing the carrier version and the SB the retail version? And is there any reason to consider the Motorola Zoom MB8600 oer the CM8200/ SB 8200? Both are using the Broadcom BCM3390 chipset and not an Intel’s Puma 6 or 7 with the latency bug. Planning to shop the CM8200 that's $180 from Cox vs the SB8200 that you can find for a little less.4.4KViews0likes3CommentsCox system won't "let" techs schedule service call to remove old filter, so no docsis 3.1
Hi, I recently upgraded to a DOCSIS 3.1 modem and Gigablast and I have what is pretty clearly the textbook problem where an old analog filter on the line blocks channels below about 600MHz, preventing DOCSIS 3.1 from fully working and limiting my speeds to ~600mbps. I can log into the modem's built-in spectrum analyzer and see that I have great signal down to 600MHz, where it abruptly drops off. The modem status page indicates I am only connecting on 20 channels, and the remaining channels have a null signal level. The status light on my SB8200 which lights green for DOCSIS 3.0 or blue for DOCSIS 3.1 is lit green. Despite all this, when I call Cox support, their "system check" says my modem is working "perfectly" and supposedly "will not let" them create the service call for the tech to come remove the filter. This should be trivial to address but I can't get it addressed. Has anyone gotten a similar issue resolved? Is there a moderator here who could reach in and get this call scheduled for me?1.7KViews0likes3Comments
Arris SB8200 Questions
Today I upgraded to the Arris SB8200 modem and when I have the coax cable plugged into the modem I cannot access the web gui using the standard http://192.168.100.1/. Also I noticed that all my lights are green and none are blue for bonded channel. How long does it take for the channels to bond and why can I not access the gui when connected to the coax network?Internet Speed Capped to 100 Mbps
I have been a Cox customer for about 10 months and within the last month I moved and transferred my service. Every since then, I have been unable to obtain download speeds higher then 100 Mbps. I have been paying for Gigablast the entire time and I also pay for unlimited data. I have contacted multiple support representatives and I have not gotten a clear answer as to why this is happening. Most tell me that it is my equipment that is causing the issue and that I should contact the manufacturer. They have even stated that if my equipment wasn't the issue, then there wasn't anything else Cox could or would do for me on this issue. I am using an Arris SB 8200 that is just about 11 months old and a new Amplifi Mesh WiFi system that is less then 2 months old, all of which where working just fine until I moved into this new place. But never the less I have contacted both of them and they can not find anything wrong with their equipment. With that in mind, I reset both to factory settings twice in the last month and I still am not able to download anything faster then 100 Mbps. The last service representative I spoke with scheduled a technician to come out to my home to attempt to resolve the issue. I am skeptical that this will work because when I asked what the tech will do during the appointment, the representative said " hopefully they can fix it, if not they will just have to run it up the ladder and escalate it." They said they had the same problem at there home and that the technician could not resolve it so they have just been dealing with it. So now I will just get to wait and see what happens on Thursday. Hopefully someone can offer up a solution a solution other just then dealing with it, or down-grading my internet package.Cox system won't "let" techs schedule service call to remove old filter, so no docsis 3.1
