SB8200

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

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 somethin

Is the model number still support by Arris? We are using it with COX and have had nothing, but lag and I read that Arris no longer supports this model.

I just purchased the SB8200 modem for my work computer. Installation & activation through Xfinity seemed to go well. All lights on the modem are doing what they should, & my computer indicates that I’m connected to the internet, but I can’t access anything on the internet…. I called ARRIS tech support, but no help… Any ideas for a simple solution before I return this thing?? Thanks!

My surfboard 8200 never came with an SSID label. How do I get that?

Purchased the sbg8200 today... isp got me access to the internet... however my led for online is not green... constantly white. Help

MY SB8200 will not power up the front lights when plugged in. The Modem was working, and then stopped after a storm. the cable tech said the modem was inoperative and installed a replacement modem. I am looking to get the SB8200 replaced under warranty and the ruckus website says the S/N does not exist, but it exists on the arris website. How do I get a replacement modem under warranty? Thanks!

All product descriptions I’ve seen say this below. Is this device compatible with Windows 11? Compatible operating systems: 4. Windows 10 5. Windows 8 6. Windows 7 Service Pack 1 (SP1) Note: Although older versions of Microsoft Windows operating systems are no longer specifically supported, they should still function with your SB8200

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 upgrade Failed after download -

Cox has no idea why I am not getting their signal from your modem to my computer via the ethernet connected to port 2, or to Google nest connected in Port one. Please help thanks

The 3rd light from the top (send signal light) is flashing green while the top 2 are solid green. I cannot get any internet connection on any device. How can I fix this? I’ve tried unplugging everything and a hard reset.

How can I find or reset my password?

I am Using SB8200 with Xfinity.1000Mbps d/l and 100 Mbps u/l plan my speeds are slow downstream is in 3.1 mode upstream is in 3.0 mode. There are four upstream bonded channels. The power values are 37 and 38 dBmV. down stream bonded channels have SNR in the ranges of 45.3 to 46 dB. The QAM256 power values are between 2.9 DBMV and 3.4 DBMV and the last one is 4.3 DBMV is this correct? I am Using TP-Link ax1800 router and am getting 300Mbps on its wired ports. wireless point gives 430Mbps. Pls comment. also, why is the upstream in 3.0 mode and not 3.1

Does the SB8200 work on Optimum with voice?

surfboard sb8200 will not go online. Check the cables, powered it off and on again, contacted ISP there's no outage in my area. It just suddenly decided not to go online. The online light is flashing. It is less than 2 years old I purchased it in November of 2021. It's still under warranty but how do I know if the modem is bad or if it's some other obscure thing? Thanks

i had a power outage yesterday and my modem went out for a second, when power came back on i reset the modem, it is lit as it should but my hasn’t come back on. i unplugged everything for a few minutes and my wifi still won’t work. this happened once before and after 2 days my wifi came back, how can i fix this

I replaced my Motorola MB8600 with an Arris Surfboard SB8200 yesterday. I don’t see a way to clear the Event Log. How do I do that? Thanks!

When I enter arris.com/selfhelp, it takes me to this address. What’s up, please?

Hi All As mentioned in the title, my signal has been dropping very frequently over the last several weeks. I’ve contacted my ISP (cox) and they gave me the run around (reboot your devices). I’ve also contacted Arris last night and the suggestion I received was to ask my ISP to increase the power on my upstream channels to which the cox tech had no idea what I was talking about so here I am… I’ve factory reset my router, I don’t believe that’s the issue. I’ve done a little research and it seems having high uncorrectables is an issue, this screenshot is from today after i reset my modem 12 hours ago. thanks. I purchased this modem and my asus router both a year ago and had no issues until recently.

My 6 year old Arris Docsis 3 died. I purchased a new SB3200. My Provider, Optimum (previously Suddenlink) got it working, but my 300 Mb connection is only running at 20 Mb. An Optimum technician came yesterday to check wiring in my apartment building and also hook up a new neighbor's account with a rented Docsis 3 modem. We now share one cable back to the pole, and his new modem runs at 300, while mine is still running at 20. He said Optimum’s phone tech help my not have provisioned my modem correctly. I need the 300 for streaming and to support a stable VPN back to work if needed. What do I need to do?

I have a new sb8200 after replacing my SB6190 after hearing of a chipset problem. Just as my sb6190 did my sb8200 is rebooting randomly through out the day. Talk to ISP they said oh its cause you have 3 different mac ids on account so he cleared them thinking that would work, it didnt. I have a tech coming out to look at the connection speeds because they are low. I also get this message in the modem log “ Missing BP Configuration Setting TLV Type: 17.2;CM “ with an date that is way off.

The top port does not work according to a comcast tech. The bottom port does work. We used the top port for 6-7 months when internet quit. The comcast tech tested the modem and said the top port was not responding. I called Arris tech support to see about getting a replacement modem and was told that this model only one port works. Sounds dubious. Any responses?
