CM8200 LAG(LACP) support/SB8200 web interface

Hi! I’ll start with my first question. Does the CM8200 support LAG(LACP)? and also I can’t access my web interface on my SB8200 from a 192.168.0.0/24 network, is this a known bug? It’s not shutdown in the config file. What is the current version of firmware on DigialCM? My ISP (Midco) seems to think that two year old firmware is up to date.

Accessing WebManager

New Surfboard 8200 User. I can access the WebManager fine with a computer plugged directly in. Should I also be able to access it when the computer is going through my switch>router>modem? It doesn’t connect for me.

Modem Help SB8200

So my original problem was that my internet connection was dropping (Xfinity) so we scheduled a tech to come out for a fix. The initial issue was resolved because it turned out that the line was damaged and the house we moved into had multiple splitters that were causing our signal to "leak" he mentioned that he was surprised that we had a connection at all from how bad it was, he disabled all the other Coax outlets that weren't in use and our issues were fixed for that day. I should note that Prior to this visit we had our Arris SB8200 modem's lights as Blue for downstream. (speeds are 600+mbs Down and 30mbs Up) After his visit the internet went down that night only to return in the morning but the lights on the Modem turned all Green and occasionally flicker (and have remained green) but occasionally it turns Blue for downstream for about 5-10 seconds whilst the connection drops only to return to green again. For ex. any stream/Netflix video/Game that is running will cut out for that

Constant "scheduled" disconnects on my modem.

My Internet goes down pretty much the same time every night and comes back on around the same time every morning. Usually it'll go down anywhere from 3 o'clock to 5 o'clock in the morning and then it'll come back up around 8 o'clock in the morning almost on the dot every day. I've talked to our Internet technician probably 20 times over the past three weeks and they have even come out to the house and they cannot find anything wrong. All they keep saying is that I should rent a modem from them which I do not want to because I just recently sb8200 for almost $150. By the time the tech even comes out of course the net is back online. I really do not know what to do. I noticed something weird in the event logs, that is goes back to 1970 on the log time/date. I honestly do not even know what to do at this point, I thought about buying a new modem to see if that even will help and I guess I could always rent one from my Internet company but I feel like since my Internet works 90% of the day

Does the SB8200 have Active Queue Management (AQM)?

I currently have the SB8200 modem that I bought back in 2017. I was looking around at modems to see if I need to upgrade to a newer model and I see that DOCSIS 3.1 is still the top of the line, so I should still be good for a while. However, I saw that the Motorola MB8611 advertises that their modem has Active Queue Management (AQM). I can’t find any reference to AQM on the Arris site, but I did find that it is part of the DOCSIS 3.1 spec. Is this just a case of Motorola listing a feature that every DOCSIS 3.1 compliant modem has, or does Arris not have AQM in the SB8200?

SB8200 Recurring Crashes

Purchased new SB8200 in February and installed and activated it per Comcast and Arris instructions. Had new Linksys MR9600 router already installed and operating. Had no trouble for a few weeks and for 3 months now recurring crashes and DOCSIS 3.1 dropped to DOCSIS 3.0. However, the DOCSIS chipset remains online to Comcast and they show the modem and system still up and operating with no indication or record of outages from their viewpoint. Had 5 Comcast technician onsite inspections and nobody has the answer. Currently have a borrowed Comcast Xfinity modem in place and absolutely no outages, slow downs, or connection issues which is at least circumstantial evidence that the Arris SB8200 modem is faulty. Rebooting resumes internet connection and service but only briefly before another crash. I do not know whether SB8200 is incorrectly configured but I changed nothing after taking it out of the box and would not know how anyway. If there is a solution I would be interested in being poin

SB8200 LEDs seem wrong after Spectrum activation

Hello, I just got off the phone with Spectrum to activate my SB3200. The LEDs on the unit seem off. I’ve attached photos of the LEDs, as well as the Status page from the web interface. Most of the videos and photos I’ve seen online show the up and downstream being blue, and the internet green… In my case, the downstream is blue, the upstream seems to be white(?) and the internet/power also seem to be whiteish green, but not bright green like I see in other photos and videos… I’m assuming my upstream is not DOCIS 3.1... When the unit boots up, all LEDs are the typical bright green. Please see photos. Any assistance would be greatly appreciated. I just want to make sure this thing is setup correctly, or if I need to escalate this with Spectrum.

I’m not sure if this was posted before but will the SB8200 have WiFi by itself? Thanks in advance.

Newly activated SB8200. Channel 24 is missing. 25 is not locked and 23 has 3127368446 Correctables

I just had this activated last night and having some channel issues and only the downstream light is blue. The upstream light is green. Spectrum says they don’t see any problems. Is this normal?

SurfBoard SB8200 wifi works but not ethernet

I have my Surf Board connected to a router and can get Wi-Fi internet just fine. But all of my Ethernet wires throughout the house connected to the router aren’t receiving a signal. I tried plugging in an Ethernet cable straight to my laptop and still no internet. I’ve tried resetting and rebooting both the modem and router and still no internet through Ethernet. What am I missing?

Is SB8200 speed limited to 800mbs?

just tried a Arris SB8200 on Vyve cable's gig plan (they say max of 960mps). I couldn't get above about 600mbs so Vyve sent out a tech who replaced something on the pole feed (anyone know what that might be?) That got me up to the 800 neighborhood but no further. Thinkin it might be modem prob so so contacted Arris tech support. He said (and confirmed when I asked a different way) that the SB8200 would not go above 800mbs on several major carriers result of a technical implementation. The tech said that I had two options:Change vyve plan to one that had max of 800 mbs, or:Buy another Arris (also DOCSIS 3.1) modem - the Arris S33. Clearly, although a modem is advertised as DOCSIS 3.1 compliant, who knows what speed you can get in the home/office installation. any way for me to get full speed from the gig plan or do I have to buy (yet) another modem??? ///

SB8200 no internet connection, all lights are solid

Hi, when I first connect my modem and activated through Zito. The modem down stream turns blue, the rest are green. I have internet connection for about 7 months now, but 2 weeks ago my down stream light turns green. Now I have no internet. I was able to ping couple of sites like google.com. I called Zito and they said they did maintenance on my signal remotely and all my signals are within acceptable range 27-37 SNR. troubleshooting steps I took so far. None fixes my problem restart modem reset modem plug in to modem directly using computer/other devices bypassing router turn-off modem, unplug coax and waited 2 minutes. Reassembled everything in reverse order. tried different DNS in router
