slow speed internet connection on SB8200

I have had the SB8200 for 2 years with 1000Mbps Xfinty internet service. I use the speed test from my Orbi Router which has showed about 930 for the last two years. This week the internet has seemed slower so ran the test and its 310Mbps down 22 up. I have rebooted the modem and router. I have asked Xfinity to ping and restart. I plugged my computer to the back of the modem port 1 but my Mac self assigns the ip to a 169 so can't seem to make that work.When I use the web app I get the following info for the downloadConnectionThe status listed show the connection state of the cable modem.

both ethernet ports not active SB8200

Hey so my modems Ethernet ports are not both active. I have 2 PCs plugged in and only one is registering a connection even they are both hardwired Ethernet into the same modem. I just got off the phone with Comcast and they said it was a manufacturing issue? Any help and support would be great.

unable to activate the modem by internet servicer provider sb8200

Just bought a used SB8200 on eBay from a reputable seller.  I tried to provision it with my Wow ISP via a phone conversation.  The rep said that there is an error “equipment must be in a special status to add it”.  She said it was locked.  I did a factory reset.  Connected it directly to a laptop without internet and logged into the modem.  I was able to change the default password to a new one.  Tried to provision again by swapping it with my old SB6183 and calling the ISP.  Same error.  While trying to provision, I can access the modem web page through my router but the username and password doesn’t work.  As soon as I take it off the cable and router and connect to my laptop directly, the username and password I created works. When putting my system back to the SB6183, they had to re-provision it to make it work (proving they removed that modem while trying to provision the SB8200).We have verified the MAC address multiple times. Is there anything I can do on my end or tell Wow what

Slow speed internet on Arris SB8200/Comcast

Trying to determine if the refurbished modem I just bought from Amazon is the problem for extremely slow speeds or if the modem is bad. Following steps I found in FAQs, I got the attached results but I’m too confused to make sense of it.

Firmware updates - Breezeline says they can't do it, Arris says they can't do it Sb8200

So out of nowhere, the Arris SB8200 on my desk yesterday, goes from blue light on DOWNLOAD to green and my speeds plummet from 1,000 meg download to 5 meg.  I of course call my ISP - Breezeline. They say I need the firmware update, but since I own the modem, they can’t do it. Come to the Arris site and it says the firmware updates are with your ISP.  For 2 straight days, I am being told that Breezeline can’t do the firmware since I own the modem and to get Arris to do it only to be told by Arris on the phone - that wants to CHARGE ME for the help since I’ve owned the modem for 14 months, says that Breezeline can do the firmware for me. I tried to factor reset the modem, did the admin and last 8 digits of the serial number but it won’t log in.  Breezeline is charging me $75 for a technician to come out and advised me to BUY a new router, which the tech visit is more than half the cost of the modem.  I feel pretty screwed over by Arris here. Any advice?

VPN Not Working with SB8200

My SB8200 modem appears to be no longer allowing me to access my work VPN.  The internet works otherwise.  I originally thought this was an issue with my work computer; but, on troubleshooting with my work IT, we determined that wasn’t the issue (I was even given a new computer, which did not resolve the problem).  I then thought it might be an internet provider issue; but, on contacting my internet provider (RCN), they rebooted my connection among other potential correctives, and determined the issue wasn’t coming from their end.  Both my work IT and internet provider suggested this was likely a modem issue. Additional context:  I haven’t done anything to my modem (I have not touched it) before the issue arose.  I restarted my modem after the issue arose; that did not correct the issue.  This issue just started one morning and has been going on for two weeks now.  I am able to log into my VPN through other internet sources not linked to my modem (e.g., phone hotspot).  Please help!

Arris 8200 connected to Xfinity coax only has external IP

Set up the Arris8200 with Xfinity Internet coax, plugged network cable to a port on the Arris8200i am able to get an IP from arris, however, the IP is an external routable IP,  there does not seem to be configured a LAN, internal only IP which I would have expected  I cannot access 192.168.100.1, as the IP I have been allocated looks to be directly from Xfinity, and I am unable to add anything to the second network port on the back of the Arris8200 as the DHCP looks to be provided direct from Xfinity how can I get to configure the Arris8200 when it appears to be not doing its own DHCP for an internal network but rather passing DHCP from Comcast? I requested help from Comcast who said to contact Arris directly for help…

SB8200 Refused to be replaced

Hi All, I bought a SB8200 a year ago but after 8 months of operation it stopped working and even through a reset and reboot it no longer would activate with xfinity’s network. I have an older sb6141 so I plugged that in and was able to activate back with xfinity no problem. I got an RMA for the sb8200 and recieved a new sb8200 and was able to activate the new rma sb8200. That replaced SB8200 lasted about 11 months this time but now same thing happened and it no longer recieves signal to activate on the xfinity network. I had a comcast tech come out and check the line everything is fine and I plugged back in my sb6141 I had laying around and it works. I went to rma the SB8200 again but am being informed that’s not possible by support because “this is the processes we need to follow there is no option to provide you another replacement”. Why can’t I get an RMA for this clearly defective unit? Why does the sb8200 stop working after one year of operation? Why should I choose to ever buy an

yesterday web manager today timeout sb8200

Mine is the SB8200 model. Yesterday I could access the “web manager” through my computer which has a router and a switch in between the modem. I called the support line and he tried to tell me I had to have a computer connected to the modem directly (I don’t think this is true as I did it yesterday, not directly connected). The line went, it might have been me, I get a lousy signal at my house (thanks tmble)  One problem, that seemed not to be an issue yesterday. Is that my home network is 10.0.0.0/24 not the 192.168. I’m not a networking expert, but if it worked yesterday… what changed. I’m not comfortable, that the providers only authorize certain equipment. The “manager” doesn’t let you do anything but view … which is something...but for a device that I own, is much less than I would expect. Especially in this newer model. I hope that my provider doesn’t have too much control over the modem. Because it’s only been “activated/provisioned” a short time, I wonder if they pushed somethi

After I installed the modem last weekend the even log shows that the modem will not update the firmware.I go to the web page on the modem using the 192.168.100.1 address, no issue.speed has been good, speed test shows 300 to 200mb download.There is no update firmware link, or check for latest updates?I noticed the firmware log shows that it is unable to update firmware. The software writers will need to test their code to find out why it shows it is corrupted on the end modem side.Here is the log snippet of 2 occurrences: 4/9/2023 17:32:15    5    REG-RSP-MP Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value;CM-MAC=1c:...;CMTS-MAC=00:01….;CM-QOS=1.1;CM-VER=3.1;14/9/2023 17:32:21    6    SW Download INIT - Via Config file14/9/2023 17:32:21    4    SW upgrade Failed after download -Incompatible SW file14/9/2023 17:32:21    4    SW upgrade Failed after download - SW File corruption15/9/2023 02:51:23    6    SW Download INIT - Via NMS15/9/2023 02:51:24    4    SW
