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.

Which DOCSIS 3.1 modem/router for wifi off but ethernet on? SBG8300?

Hi, I can’t run wifi here and need wifi turned off. I was looking at the SBG8300 and see that wifi can be disabled. The description says that it includes a wifi router though. So, if I have wifi off, will it still support routing for wired ethernet devices like PCs?If so, how many wired devices can it support (I have a 12 port switch I will connect it to)? Thank you!

Can't log in to my DG3450, hard reset didn't help

So I’m trying to login to my DG3450. I got it from the cable company, who cannot help me at all with this. It asks for username and password, which should be “admin” and “password”. I tried it and get “Invalid Login Credentials.” I also tried using the password for my network. The cable company tech support person said that I had to use my network name for username and my network password for the password. Never heard of such a thing before, but tried it and it gave me “Operation Failed.” So I’m thinking that whoever had the unit before me changed the password. The cable company tech support said that I’d have to do a factory reset, even though I’ve done those before and it doesn’t actually reset all of the passwords and such. So I did it and, of course, it didn’t work. So how can I get access to my router if someone else changed the password and there’s no way of getting it from them?

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?

can Surfboard SB6190 connect wirelessly to internet? acting almost as a router on its own?

I need not only help for that question, which I suspect the answer is no. Here’s what’s happening:I formerly lived alone and used my modem and Linksys router without issue. I am now living with family who was very powerful Wi-Fi all throughout their large home. For a month- I’ve been able to connect without issue until today. My smart TV, MacBook and iPhone will not connect. Cannot find network or internet, my initial thought was to hook up reputed next to TV so has to get signal, right? But it’s old and cannot get internet from Wi-Fi (to then route out..). It has to be hardwired to internet source- which is wayyyy on other end of house. Help!!

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

New Surfboard SB6190, is it possible to disable any of the LED indicators?

Very happy with my Arris SB6190 that I purchased from Amazon last week. Called my ISP to add it to their system and speeds have been great.I logged into 192.168.100.1 and checked Configuration. I enabled the “Energy Efficient Ethernet” option which seems to be working fine. I was also looking around online and saw there may be a way to disable the LED lights on the SB6190, but I do not see that option when I login to the device and check “Configuration”.Is this a carrier or otherwise issue (if that’s fine it’s okay)? Alternatively, is there a way for me to see this configuration option that seems hidden from me right now?Product information page shows the following -Standard Specification Compliant: ARRIS DOCSIS 3.0 Cable Modem / RetailHardware Version: 3Software Version: 9.1.93VAgain, everything is working fine and I am a happy customer. I was just curious if there was a way to disable some of the LEDs.Thank you in advance for any help,Seth
