No Ranging Response received

Hello everyone ,Today, I purchased a used (preowned) cable modem, specifically the SB8200 model. Upon exploring its Event Log, I noticed several recurring issues related to synchronization and ranging failures, such as:1-SYNC Timing Synchronization failure.2-No Ranging Response received.3-Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received.4-Started Unicast Maintenance Ranging - No Response received.5-16 consecutive T3 timeouts while trying to range on upstream channel 8.6- Unicast Maintenance Ranging attempted - No response - Retries exhausted. Could someone please help me understand what these event logs mean? Do they indicate a problem with the device? Would it be advisable to return it, or are these issues not significant?Thank you in advance for your assistance.

Unable to access the internet on SB6190

I can’t get my router hooked up. Only the first two icons light up. When trying to access the internet I get a message that says this device is blocked by access control in the router. How do I fix this?

Can't log in to Surfboard Central management console -S33

I just installed and set up an Arris Surfboard S33. We are running Windows 10 on our PCs. When I go to the Surfboard Management console at 192.168.100.1 and enter “admin” and “password:” as instructed by the user manual, I get an error message that the username and password are not correct. This happens with all browsers. Can anyone provide any guidance, assistance or correct instructions? Thank you.

Connecting SB8200 modem with Netgear and Vonage

I have an SB8200 modem. Currently, my modem is plugged into my Vonage phone modem, and my phone modem is connected into my Netgear Wifi router. I want to connect my SB8200 directly into my Netgear router and use one of the ports on the router to supply my Vonage modem. I tried this setup; however, I cannot get the Netgear router to recognize the SB8200 modem; i.e. I get no connection into the router.

Support, contact sales

If I purchase a new modem, can I call and get support? It’s too bad the company doesn’t even have a sales phone number!!!

Cox is telling me that my Arris SB8200 is bad, but I don't think the tech was competent.

https://imgur.com/a/jqy8wznImage files of the modem status in the link above.Tech came in, put a simple continuity tester on the barrel connector in basement and declared I have a bad router. I insisted the router is fine (it's a couple year-old Asus RT-AX86U).So then he did some actual testing on the outside line and said all is good. But he did change out an attenuator where the line comes into the basement, is barreled together, and runs directly to my modem. He said it was the wrong attenuator for the service.I have whatever the top package is... gigaspeed or something like that.When I first had an issue last night, I was getting 800 download speed, and only 1.5 upload. Although today when I checked, before he came, I was getting 800 and 40. After he left I am getting 670 and 11.His contention is that the modem is fluctuating and needs to be replaced.I feel like he was initially being lazy and didn't want to do any real testing.... so I am still not confident in his conclusion.

SIP being blocked on SB8200

I’m trying to get a SIP circuit to register, but the SB8200 (used with Xfinity) is blocking something. When I switch to my AT&T circuit, the SIP comes up just fine. Is there a manual for this device? I can’t seem to find one.

Modem activation Sb6190

Hello, I have followed the instructions to activate my modem - SB6190.  The middle two lights are blue.  The online & power buttons are white.  I do not have internet access.  In addition, the setup instructions requested I use the COAX cable provided by my network provider.  In doing so, I had to unplug the coax cable from my router as I only have one Coax outlet In my apartment.  I believe this has now resulted in my router being disconnected as well.   Please advise.

Internet randomly drops and speeds are slow - S33

S33 & Xfinity gigabyte plan Past few days  I have been experiencing frequent outages. Usually a reboot of the modem and routers resolves it but the past few times the speeds are not coming back to what they should be. I took a look out the downstream channels and saw a lot of corrections and uncorrectable(s). This screen shot was taken with a modem uptime of about 20 minutes.   Spoke with Xfinity rep and basically said everything is good on their end and to contact manufacturer.  If anyone could provide any suggestions I am all ears.

S33 Upload Speed Issue

Like most I’m on Xfinity with my own S33 modem. I updated my service to an 800Mbps/100Mbps plan and haven’t been able to get anywhere higher than 11.8Mbps uploads on the Xfinity speedtest site. A tech came out and ran a new line today and we removed a splitter that was no longer needed and he said the signal levels were much improved. The only thing I’ve seen improve so far is the number of correctable and uncorrectable errors on channel 1 have gone away with the new line. Otherwise, the power levels on the upstream connection actually seem to have dropped (maybe that’s ok) from 47.5 dBmV to 43.0 dBmV. I’m still not getting any higher than the 11.8Mbps even though I’d expect to at least hit 20Mbps if they still haven’t opened up support to 100Mbps to the S33.Here are the levels from the modem status page after the new line was installed (and splitter removed). Does anything stand out as a problem? Xfinity support replied that they’re showing downstream SNR is at 44.5 and your upstream

SB8200 Two Separate Subnets

I was hoping to setup 2 routers on a newly purchased SB8200 modem. I had one router configured as 192.168.1.0/24 and the other as 192.168.2.0/24I have been Googling but am stumped. I was hoping to have 2 isolated networks - if it’s possible.If there’s a KB floating around, or if anyone has some guidance, I would sure appreciate it any help.Thank you, and my apologies for a rookie question.
