SB8200v3 only 1 connection even with switch

I got connected with xfinity with my SB8200v3 and I used 1 ethernet port to connect a switch to. I have 3 PCs connected to the switch but only 1 is getting internet. I tried looking into the setting of the modem and the app but neither one will give me any options. I have been trying to look this up and can’t figure out anything other than I might be in bridge mode but can’t figure out how to get out of bridge mode if I am.

Intermittent internet connect on S33

First, over two months ago, I had a defective unit that was making a hissing sound and showing a white light. Unfortunately, the unit was bricked and could not be fixed. After two weeks of dealing with Arris customer service, they sent me a new unit. However, once I installed that unit, my internet started dropping signal twice an hour and buffering throughout the day. This is the second unit that has been total trash. I downgraded to my old SB8200 and my internet has never been more stable. Unfortunately, I don't see a solution for this issue, so I have to try to return the new unit to Best Buy. I just wanted to give a warning to anyone else having the same issues.

SB8200 Not Connecting to Optimum

I just recently purchased an SB8200 and it will not connect to optimum, I’ve had a tech out and he was able to connect one of their modems to the network but couldn’t get my modem to connect.  Phone call with support also was unhelpful as they said they don’t know why it won’t activate and they said to reach out to Arris.  It just gets stuck on solid UP/DOWN lights and flashing connecting and than cycles that forever.  Below is the event viewer from the last time they tried to activate the modem.14/04/2024 02:14:18    notice    GUI Login Status - Login Sucess from LAN interface; client ip=[192.168.100.20];CM-MAC=8c:76:3f:fc:ce:7b;CMTS-MAC=00:01:5c:c0:04:4a;CM-QOS=1.1;CM-VER=3.1;14/04/2024 02:14:08    notice    GUI Login Status - Login Fail from LAN interface; client ip=[192.168.100.20];CM-MAC=8c:76:3f:fc:ce:7b;CMTS-MAC=00:01:5c:c0:04:4a;CM-QOS=1.1;CM-VER=3.1;14/04/2024 02:14:03    critical    Config File Rejected due to Invalid or Unexpected TLV 11;CM-MAC=8c:76:3f:fc:ce:7b;CMTS-MAC=00:

S33 solid blue but no internet on any devices

Xfinity says no issues on their end. When I try to factory reset, it just automatically connects back to Xfinity again, no configuration needed. I’ve tried holding the reset button for 10 seconds, 20 seconds, and 35 seconds (both with the coax connected and without).  Connecting via Ethernet does not work either. I get an error saying the DHCP is unavailable.  Any suggestions before I go insane?

SBG8300 - connected devices are not listed on SBC app.

When I open the surfboard central app it shows zero devices connected.  I know this not to be true because every thing is connected.

S33 modem solid amber light then white light flashes and high pitch noise from modem.

Hi, this morning my modem appears to have broken. The Amber light stays on for a few seconds and then the white light flashes and this cycle repeats.Its also making a high pitch squeak every few seconds. I’ve attempted to reset the router several times but nothing appears to happen.This seems very similar another post on this forum but it’s marked as solved with no solution specified. Only instructions on how to access the web console. Which I’ve tried but have been unable to do so, the page never loads.Any help would be greatly appreciated.

Surfboard Central app Not Working

I recently installed an S33. Activation with surfboard central was fine and had no issues with xfinity.  Internet is working fine. The app gives an error when going to the network section that has lasted for several days."We are experiencing an issue with our Back-Office services. Please try again later"Attempting the network scan gives me a never ending progress wheel. It never completes. I have factory reset the modem, no settings have been changed, app has been reinstalled.  Issue persists.

suggestion to buy a modem with 2ports and VOIP support

 We are trying to replace the services we rent through our cable company. We have a multi-level home with lots of devices and the Eero mesh system has worked well for us. We need to purchase a modem with two ports, latest technology and fast speeds - we pay for download speeds of 1 Gig Internet and 6000 GB of data. We need a two port modem that will give us the fastest speeds through the modem. We also use VOIP. Which Arris modem do you recommend that is compatible with the Eero mesh system and meets these requirements?  Thank you for your wisdom and advice

intermittent internet connection on S33

I purchased an Arris S33v2 last November. We have been having at least 2 to 3 short dropouts daily. We thought it might be a cable issue as the upstream voltage was a little high and downstream was a little low. (Also saw some UCD invalid or channel unusable messages in the event log)Ran a new RG6 Quad coax directly from the outside cable box to the modem. The voltages fell within the normal range but the daily reboots continued.The Xfinity tech recommended getting a different modem. I already had my old SB8200 so I installed it. It has been up several days now with zero dropouts.How do I go about getting a warranty replacement?
