SB8200

Have tried everything, but can’t get 192.168.100.1 to load in a web browser, therefore can’t access modem settings that way.  How can I change default password?  Is there a way through the Surfboard Central app?

Pretty much the title. Have had the modem for many years. Got a new router and went to set that one up. I unplugged the power from the modem and then plugged in the Ethernet for the router. After the I plugged the power cable back in, the only light on is the green power light.

Hello, nice to meet you. My SB8200 modem stopped working. I got home from work and when I looked up, I had no internet access and the modem's lights were off. I just bought it on January 30th.

New to me SB8200 which replaced my CM8200A. Last night I got into the modem with the 8 digit serial number. After getting in, it asked to reset the password. Did that and copied the password to a file in case I need it. Was working fine. This morning I tried to get in with the new password and it failed to do so. Tried the 8 digits SN and it failed. Tried the “password” and it failed. I doubt this is normal because I haven’t seem much info here on failed passwords. By the way, I am using “admin” as the log in. Thoughts from the experts here? Appreciate it. Thanks

Arris sb2800v3 not showing up as home network on xfinity 

Can you please tell me how to access the event log on a surfboard SB8200? 

I have an SB8200 and I’m not sure when it was purchased or how old it is. I know it’s not under warranty. What is the best way to get the ship or manufacture date of my specific modem?

My ISP plan is 200Mbsp. Works for what we have now. And unlimited.  Looking to upgrade from ARRIS SB6182. Will the SB 8200 work?  or is it too much for what we have? Cox cable wants me to get more data speed. Thank you for any info.

For the past few days, I haven’t had an internet connection. My provider (Xfinity) says their side is working, and my router (ASUS RT-AX58U) is indicating that this modem is the issue when I check the network diagnostic. I’ve tried power cycling, factory resetting both the modem & router (separately), and moving both to a different coax port. Unfortunately, none of that has helped. I can still see & connect to the network, but there’s no internet on any of my devices. if you have any suggestions as to anything else I might try before resorting to a technician visit from my ISP, I would greatly appreciate it. Thank you!

Internet has been spotty for last 2 weeks. Replaced old Netgear router w new Archer AXE75. Connected it to Surfboard 8200 v3 that was bought 3 months ago. Now there is no Internet at all. Do these 2 work w each other? Or do I need something different. Cox Communications is my service provider.

Just got this Modem on sales from Amazon and is an SB8200v3 model and just had it swapped over w/ my cable company. All is good but want to know if ALL 4 lights stay on full time compared my my older SB modem where the globe light on the bottom would flash to show connectivity. Is this normal on this new one? Everything acceses just fine.

The modem has stopped connecting to the Internet.  I have had it 6 weeks.  Goes off line all the time and has to be reset.  I can’t participate in the live chat because the site doesn’t recognize my serial number and I’m reading it from the modem and the box.  Nothing.  This is terrible customer service. 

Hi folks, I had to hard reset my SB8200 after it started to lose connection to Optimum. The status of the channels now show “Locked” and I can’t seem to connect to ISP. What do I do?

I have a SB8200 modem that has stopped working. My internet provider came by, tested the modem and confirmed it’s receiving the signal from the provider, but not then passing along the signal to my laptop (if direct wired) or my wireless router.  I checked your site and based on the serial number of my modem, it is under warranty until Sep 13, 2026. I’ve tried to find how to submit a warranty claim on your site, but any instructions I’ve found appear to keep sending me in a loop from one site to the next. Can someone please direct me to the precise site that explains how to submit a warranty claim on my modem?Thank you.

When power is restored after an outage, SB8200 modem does not power back on.  I have to power cycle it to get it to boot up.  This is a problem when traveling it remains off until I return home and power cycle it. What would cause this?

I have a new SB8200. Want to register it for warranty. But I cannot. When I go to the site, I enter the Serial number and model number and it says there is no match. When I call tech support, I get disconnected. When I go to chat, it’s not available (in their business hours). I have not yet found an email address. Can anyone here help me?Thank you.

My SB8200v3 upstream and downstream lights stay solid but the internet light keeps blinking. My old SB6183 was working just fine when I connected it however this new modem doesn't want to work.

how do i disable the 5g on my 8200 to connect to a 2.4g only device 

Need to RMA a SB8200

How do I find out what the password is for the recent bought modem

I AM JUST OUT OF WARRANTY AND MODEM HAS A DHCP PROBLEM. HOW TO RESET MODEM?  

I don’t have the admin password for my SB8200. I tried “password” and the last eight digits of the serial number, both upper and lowercase. I tried the 10 second reset, and could still not get in so I tried holding reset for 30 seconds and neither admin/password or admin/(serial last 8) works.Is there a more effective reset procedure? Is there any other possible default password?

I would like to change my WiFi password and find a way to monitor devices 

Wrong service provider, provider should be Sparklight not New Wave. How can this be corrected?

I purchased an Arris Surfboard SB8200 back in January this year and it just kicked the bucket a couple days ago. Everything was running normally, but suddenly I lost WiFi and I noticed that the Surfboard didn't have any lights up. I unplugged the unit and it was very hot to the touch. Clearly, the hardware has failed.I took the unit back to the Best-Buy I bought it from, but since I didn't buy the protection plan, they told me there was nothing they could do. They let me know that I need to contact the manufacturer and ask about their warranty. Apparently there is a one-year warranty, and I should be eligible since the unit didn't even last a full six months.I went to the URL on the bottom of the device, www.arris/consumer, but this seems to now re-direct to a website for the company CommScope. I made an account there and tried to submit an RMA request (no clue if I am in the right area of the website), but it requires me to select an address, none of which I am located at. Then it ask
