SB8200 - Docsis 3.0 to Docsis 3.1

My SB8200 will not connect to docsis 3.1. I have a spectrum gig plan. Spectrum tells me my plan is docsis 3.1but my modem is stuck in docsis 3.0. I don’t see an option how to change the setting in the management page. spectrum is no help and tells me to contact the manufacturer. Any help would be greatly appreciated Also I cannot access the management page while the modem is connected to the net. I can disconnect from the net and access the page.

SB8200 faults out once or twice a year and can't access internet while connecting router

I have a SB8200 modem and for no reason at all it drops our internet connection and I have to call for a paid service to walk me through the issue to correct it. Have my computer connected to the modem and it says everything is working fine but the indicator lights are: power - solid green, Receive - solid blue, Send - solid green and online solid green. I can access the internet when connected to the modem but my nighthawk router will not connect. I have logged into the modem manager but don’t see anything out of line there either. Any ideas on why I need to call for assistance one or twice a year to adjust my settings to allow it to work again? Wifi - Netgear Nighthawk X6S, AC4000 Tri-band, model - R8000P

S33v2 light solid amber, blink of bluegreen then back to solid amber. No connection to any device but internet shows connected. Power cycled the provider and Arris devices, did the paperclip reset on the Arris device and checked the Ethernet and coax connections and found no problems with those. No change, any ideas??

New SB8200 all green lights

So, yesterday I purchased a new SB8200 and had Cox activate it. However, while it works all the lights are Green, shouldn’t two of them in the middle be Blue? I’m 80 and not that tech savvy.

Cannot connect to SB8200 Router has IP address

I have an Airport Extreme which evidently automatically takes the 192.168.100.1 IP address so I am unable to connect to my SB8200. Any suggestions?

I can no longer restart SB6141 modem from configuration page!

On the configuration page there used to be a button “Restart Cable Modem”. This button has disappeared. Who changed the firmware and how can I get the button back?(My ISP denies that they have changed the firmware on the modem that I own)EDIT: When I remove the coax cable and restart the modem, the reset and restart buttons are there! However, as soon as I put back the cable the buttons disappears 🙄.How can I keep the buttons with the coax cable connected?Several years ago, the buttons were there even with the cable connected..

The power went out and when the modem came back on it only flashes green. I pulled the power out for 30 seconds but no change. I tried doing the reset button while I was flashing and still only flashing green. Not sure what else I can do?

connected without internet S33 modem

I've unplugged every cable, replugged, waited 5 minutes while everything was unplugged, waited 5 minutes after modem had solid light before powering the router, attempted powering both router and modem at the same time, tried timing them to be on at the same time, done a soft reset, and my modem still won't connect to wifi. Its done this before multiple times, but till now ive been able to resolve it and see it finally connect, but this time it will not. My asus router isn't old and it says theres a problem at the modem. My internet is fine. This only happens if the power goes out and it tries to reset.

SB8200 Not Allowing me to connect multiple items via ethernet

Hello, I have a small mesh wifi network comprised of two W12’s (one of which is operating as router connected to the SB8200 via ethernet) and the other which acts a node. My GF just recently got a stay at home job which she got a desktop for and it needs to be connected via ethernet. When I went to connect the ethernet into the other port initially it wouldn't connect to the desktop. So I rebooted the system to which the ethernet worked but the router wouldn't connect. After hours of trouble shooting I found myself here. Any recommendation as to how I can hard wire a device to my modem while still allowing my wifi to work?

My Sb6190 isnt showing the lights

So every single light is showing blue except the power and online light. The light is kind of white but not on if that makes sense. Everything else is working fine other than the fact I can’t connect to the internet, it’s not even showing up anymore. I’ve tried resetting it and turning it off and back on again but nothing seems to help. What’s wrong with it?

Seeking Primer Material Xfinity -> SB 33v2 -> TPLink Router -> LAN

I’m replacing my Motorola MG7500 with a SB33v2 which will service my TPLink Archer router. I think I’ve established service to Xfinity, but can’t seem to raise the router in any configuration -- my LAN connection shows a router through Xfinity which makes me believe the router on my side is being circumvented.I am getting traffic from the internet back to my laptop in the below configurations:cable → modem→ router→ switch->laptopcable → modem → router→ laptop.Do I need to reset anything on the modem proper?Is there some guidance on troubleshooting?Is there an intermediate step available to connect to router directly? Thank you for any support you can offer. Sincerely,CW
