Two different SB6190's reboot themselves multiple times per day with the same log messages

I’ve had a SB6190 that was working fine for more than a year. A few weeks ago, it started rebooting itself multiple times per day, but once it rebooted, it reconnected to Xfinity just fine. Unfortunately, it would just do it again in a few hours, and obviously, internet service is interrupted for about four minutes each time. Xfinity sent a service tech, who checked and said there is nothing wrong with their cable. He said the SB6190 should be fully supported on the Xfinity network, and suggested I buy a new one. I did buy a new one, and it behaves exactly like the one that is more than a year old. It works fine, until it reboots itself, and it does it just a frequently as my original SB6190. What do I telll Xfinity, since it’s obviously their network? Two different SB6190s (both tested when plugged into the wall and also tested when plugged into a UPS/surge protector) are acting identically. In addition, there seems to be two entries in the logs that correspond to the timing of the re

Surfboard SB 6183 modem can't be activated with Optimum

Hello, I have a refurbished Surfboard SB 6183 modem that I purchased off of Amazon in 2017. I’m trying to use it on my Optimum Altice account now but support is saying that they can’t get the modem to activate. Any idea why it can’t be activated?

SB6183 Intermittent connection

My internet drops out intermittently (usually for a few seconds at a time, but VERY often). I’ve power-cycled both router and modem. I checked and have the latest firmware upgrade for my router. How can I explore to see if I could be having a problem with my modem? Thanks for your advice!

To check Ethernet Connection on SB6183

My SB6183 modem is working and the ISP confirms I have connection from their side but I am getting no indication via lights that the Ethernet connection is working. How can I confirm if the Ethernet port is damaged or not?

403 Forbidden not resolved

I see that others are also getting the 403 forbidden message when trying to connect to the cable modem interface. My modem is the SB 6190. I tried EVERY suggestion listed in this forum, and chatted twice with Arris tech and we went thru all steps, no go. I asked both Arris tech’s do I actually NEED to connect to the interface, and if so why? Security reasons? Both tech’s told me to rest assured that there are NO security issues if the interface can’t be reached and UN / PW can’t be changed. Is this true? Anyone know if this is true? If it’s true, why is there a need at all to connect to the interface? Really a terrible feeling to be locked out of the interface and not knowing if I’m now vulnerable to being hacked. I’m going to get a new cable modem. NOT and Arris.

Important to change UN and PW with SB6190?

Hey all. So my new SB6190 is activated and working (Optimum is my provider). I’ve tried what has been suggested in this forum in order to log in with 192.168.100.1, yet haven’t been able to. Question...does it matter? Is it important to get access in order to change UN and PW? Is there a security issue if not? Not too happy with Arris that logging in is an issue. I was going to download the mobile app but I don’t download apps that require access to what’s on my phone. Thanks.

Brightness of LED's SB6190

Hi. Surprising how those little (especially the blue ones) LED’s light up my spare bedroom at night. I’m guessing there’s no way to dim them on the unit itself? There’s no user manual and I’m unable to access the device with that IP address shown in the quick start guide. Sux but looks like I’ll have to block the lights with something.

Exchanging Arris TM822 for SB6190 - Set up

Hi. I’ve spoken with Optimum, and the SB6190 is supported by their service. Before I get started disconnecting the TM822 and connecting the new SB6190, would be great to get some input from experienced people here. I have a Linksys EA7400 wireless router connected and working presently, I’m hoping that it won’t be an issue to connect to the new SB6190. Possibly any videos which might help if/when running into any issues? Thanks very much.

hook up to star link with SB6190

I have Starlink set up in my barn that is approximately 150 ft from my house. I ran a RJ45 cable from the Starlink modem to the house. Will the Arris SB 6190 work to bring the internet to the house? Note there is no coaxial cable just the Ethernet RJ 45 from Starlink to SB 6190
