W21 online but not showing in app. Cant add satellite

Modem - S33Router - W21 Dual PackProblem - I have no issues adding my S33 modem to SB Central but after that, I add my first W21 router and after completing successfully the app asks me if I want to add a satellite “now or later”. Whichever I choose it then shows a loading wheel in front of the app and I cannot do anything else. If I wait it out, app crashes. If I force close and come back, it starts all over again. Only showing my S33 as the only device on my network. However, the first W21 is online, blue solid LED and transmitting wifi. I’ve opened a case with Arris but doesn’t seem to be going anywhere. I’m ready to return everything and have Xfinity send me another rental.  NOTE. I’ve tried 3 different iPhones and 2 different iOS versions.

Cannot access Web Manager page for SB8200

Bought an SB8200 cable modem from Amazon to replace an old SB6141.  Package appeared to be sealed and modem was wrapped in plastic.  Activated successfully with my Xfinity account.  Functionally, it seems to be okay.  Speedtest.net reports no change in speed; ~80Mbps down and 5 up.  My Xfinity service is supposed to be 400/5 and I was hoping that a newer cable modem would bump my speed up.However that’s not why I’m posting this.I cannot access the Web Manager page at the default IP of 192.168.100.1.  The previous SB6141 had the same address and I had no problems viewing the page.I’m using Firefox 91.13.0esr (64 bit) but have also tried Chrome.  Tried both http:// and https:// and nothing.  I’ve tried the usual power off-power on routine with no change.  I CAN ping 192.168.100.1 and see it.  Remove the ethernet cable from the SB8200 and ping fails so I’m pretty certain there’s no other device at 192.168.100.1 on my network (192.168.x.x).  Ethernet cable from SB8200 goes to my ASUS RT-N6

WIn10 Wake-On-Lan for NVG443B Version: 9.3.0h3d36

I’m having trouble with sending a Wake-On-Lan magic packet over my wireless LAN. I suspect the ARRIS router is blocking the broadcast. Please advise if I need to configure the firewall, and if so how? Thanks in advance.

SB6190 speed

Hello everyone. Have been looking and researching SB6190 spec and all reviews and packages advertise it as up to 1.4Gbps. Purchased a new one from Walmart today but the box now says up to 1Gbps. However, all websites and packages say it’s up to 1.4Gbps except for Arris Webpage. Not sure what the actual speed spec is for SB6190 and whether there’s an update that I need to do to bring it up to 1.4Gbps or if I just have a slower version of it. If anyone knows the story behind it, I’d really appreciate it.

Malfunctioning Modem/Router

My brand new Arris Modem/Router was working fine until a Comcast technician unplugged it last night.  Now nothing works.  No streaming, E Mail Googling etc.  Nothing.  Comcast tells me I am getting a good signal and that I should contact Arris to address the problem.  I rebooted it this morning and I have no Internet service.

SB8200 Clarification

I’ve had this modem for a couple years with Xfinity and so far no issues to report.  Recently, I’ve been getting emails from Xfinity that I need to upgrade my modem to match the speeds I have.  I’m on a 1200 Mbps service plan. I thought that was strange as the box this modem comes in states download speeds up to 10Gbps.  Xfinity tells me that this modem only supports 1Gbps.  I looked on Arris’s website and now I see that the information appears to have changed.  What am I missing?  Does this modem not support above 1Gbps now?  I bought this thinking I was future proofing but it appears that I was wrong.  Appreciate the help correcting my thinking.

Internet Connectivity to Honeywell Gateway SB 8200

I recently install and SB 8200 Modem and every devise that I have had no problem getting internet connectivity on every device except my Honeywell Gateway.  I use a Netgear switch.Working with the Honeywell team they are convinced that there is something preventing their gateway from connecting to the modem.  They sent me the email below in an attempt to do some trouble shooting:I am sending you some network recommendations that might cause that your thermostat can't connect to your home network. You may your ISP (Internet Service Provider) and check the next settings. 2.4Ghz, or 5GHz network. The TH9585WF will only connect to the 2.4GHz.  Enterprise Business Networks requiring RAS, Guest networks, or networks requiring Web Portal authentication are not supported. Recommended WPA2-AES Network Security Protocol  (Also known as WPA2-personal, or WPA2-PSK) are the primary industry standard Wi-Fi connection Configuration.  WPA3 is not supported by our devices.  We do not recommend any use

SB8200 (v4) not attempting firmware update

SB8200 hardware version 4 is not attempting to update firmware after activating with Spectrum. I need the update so that I can enable link aggregation.  I used the Spectrum live chat feature and the agent told me they won't push an update because it's 3rd party hardware even though it's on their approved device list. I tried a reset to see if that would make a difference, but no. I'm including a copy of the event log from after the reset, in case that is any help.

Carrier Locked SB6183

Hello, so I had purchased a SB6183 a few years ago, and had it working with my carrier which is optimum/altice at my old location. I moved and transferred my service to my new residence, but when I tried to use my original modem I had purchased, I was getting an error preventing me from using the modem. I called optimum/altice and they explained to me that for some reason the Mac address on my modem is still associated with my previous location and they couldn't fix it right there and there and would escalate it to another divisions. I haven't heard anything from there on the matter, but before I reach back out to them, is there any alternatives or fixes that I could do on my own, since the modem is mine and shouldn't be locked out because I moved. Thank you.

SB8200 dropouts and errors. Comcast has been here 3 times and said everything is fine.

Comcast said the first time our netgear modem may be too old, even though it was a docsis 3.1.  We got a motorola a few days later and had the same issues.They came back a few weeks later and replaced the old rg58 drop (they should have done that a long time ago)  and ran a new cable from the pole all the way to the modem outlet. Signal improved, dropouts slightly improved but still goes out for minutes to an hour. A week later they came back again, replaced a port on the pole and adjusted the DB down a little. But didn’t make any difference. On the comcast board someone said that motorola may have a firmware issue causing all the errors on the OFDM channel. So we got the SB8200 and this one too is having dropouts and the log is full of errors. Comcast says everything looks fine on their end.  It’s doubtful we had 3 bad modems in a row. All these errors are just from just 2 hours of uptime and we are loosing connection every 5 minutes now.
