flashing green. model s33v2

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?

Hi, I am trying to set up parental controls. I have a SB8200. I downloaded Surfboard Central, but don’t see the option to create users or set up rules to manage their screen time. Thanks for any help!

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?

Best Surfboard Modem for Comcast 150mb with multiple computers

I have an office with about 5-7 computers needing access to internet at one time.  The speed I am going to be purchasing is the 150mb/100mb and I was looking at the sb6183, but wasn’t sure if there was a better modem for the setup I have. Thanks!

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

How to get return/refund for the defective modem - SB6190

Purchased this modem 4 months ago and it worked perfectly until “I moved it on the shelf.”  Seemed to go into a standby mode - has power but does not receive internet signal or reset when I tried to do that.  Called cable company to check it out, tech said it’s a modem problem and recommended I purchase an SB6190 DOCSIS 3.0 Cable Modem (which I just did).  My question ~ will ARRIS allow me to return it, and refund me for this defective modem? (I sure hope so.)  Not having internet, because of this defective modem, has put me in a difficult position as I work two days at the office, and three days from home.

GUI web portal doesn't work on SB8200

The manual instructs me to open a browser & enter an IP address to log in to change the name / password for the modem.  When I do so, I get an error message saying the site can’t be reached.  I’ve tried on 3 different browsers and I get the same error message.  I have the SB8300.

sb8200 modem reboots randomly several times a day

I have an sb8200, and it reboots randomly several times a day. The cable company says everything looks good on their side. Is this a sign of a bad modem? I checked all the connections and reset the modem to factory settings,  but even after doing that, it still reboots, kicking us off all our streaming devices.
