SB8200

Hi! I recently upgraded my ISP plan to go from 400mbps to 800mbps down. After trouble shooting directly with my ISP and my router, I still receive the same speeds (~400mbps down). I have tried testing my speeds on different devices and different locations. Is there anything I can do directly with my Surfboard Modem or settings I can configure? I don’t have a device right now that has an ethernet port that I can directly plugin to the modem to check speeds from there. Thank you!

I had to replace my old modem due to it being destroyed by a family member, but when I received a new modem, it did not come with a wifi security key unlike my previous modem. Am I just blind or dumb?

I connected my new modem, then 24 hours later no internet. The modem is hot to the touch and doesn’t light up. Should I just return this thing and get a different brand?

SB8200 bought around Oct. 2022. Still in warranty. Will not connect to internet. Power light and second light are on, third light comes on and blinks twice then goes off, fourth light never comes on. Operated very hot before this. Dropped out several times during my internet session and had to reset power to correct. Need someone to help me replace modem. I worked with an Arris tech for a long time on 06/23/23. Called and had a technician come out and check my internet. He said there was nothing wrong. No luck! He installed a modem off his truck and told me to check back with Arris. HELP! 

How can I improve my wifi calling?

Spectrum said they not no longer Version 6 SB8200 is compatible with their network. Do I need to buy V7? Or can possibly update firmware??

SB8200 modem has all lights on as expected but I’m unable to connect to the network.  I called out internet provider and after running some tests said it must be the modem.  What else can I do to diagnose the problem since I cannot get help from the internet provider and I do not seem to see a phone number for tech support for my arris modem?  Any help would be greatly appreciated.  

Frist time. No internet. Only accesses Spectrum activation page. I thought they should all be green. 3 are green and one is blue (download).

I can navigate to Yahoo and Google but no where else, VPN no longer works and will not connect to my linksus wrt610n router. Had no issues with my sb6141

I am trying to get my Roku started and my SB 8200 warranty has expired.  I just need to figure out the network name and password so I can get going with this,

I have an Arris SB8200 modem that has worked well for several years, with no issues. There were some early on, but those were resolved with line repairs by Xfinity. A while back, Xfinity gave me an automatic upgrade to 1200 Mb per second, but I kept my gigabit modem since I was happy with the lower speed.  Recently I have had intermittent dropouts on streaming music and video services and the modem reception light that had been blue(Docsys 3.1) is primarily green, with occasional brief attempts to change to blue. Initially xfinity service suggested it was due to upcoming line service in the area. That time has passed, and nothing has changed, so today they told me the problem was incompatibility between their upgraded equipment and my modem. They suggested I rent equipment from Comcast and that would solve the problems.  Does anyone have any suggestions or experience with this kind of issue? Should I have a technician come out and check the lines on my end to determine what else mig

How can you tell how old ARRIS SB8200 is. Like when was it made. Can you tell from the serial number?

Is SB 2022 MOCA enabled? thanks

So what is the difference between red & blue box? Older and newer? Other and 10 Gbps and 2 Gbps 

The modem has worked perfectly for over a year.  Now the downsteam light is off while the other three are normal.  I have done a hard reset using the button on the back.  The modem works but then it won’t work and we have to reset it.  I accessed the modem and all the levels seemed ok.  Is this a warranty replacement issue?  I can send you a copy of the status page.

So I switched from a old arris modem / router to a surfboard sb8200. I purchased a router with it since the sb8200 is only a modem. Now when I try to log into the modem to adjust settings I cannot log in. I have forgotten my old user name and password and I have attempted to reset the device and use the admin / password login but it still tells me incorrect username and password. Is this something I am going to have to contact customer support for? Or is there an easier fix?

Hey everyone. I noticed my receive is light not on and thr other 3 are like a yellowish green. The internet still works but reading the manual says all the lights "should" be on. Anyone got any insight? Thanks!

Hi everybody. Just hooked up my Arris SB8200 and now some of my Roku channels won’t load. Any ideas why?

I have a new SB8200 on a new install. I can access the internet fine when wired to one of the SB8200 ports. When i connect my router’s WAN port to it, no device on my router gets traffic. There are no settings for bridge mode that I can find in the web UI of the SB8200. How can I get my router to work? It IS in DHCP mode for its WAN port.

I have recently purchased a SURFboard SB8200 and was working thru the activation with Xfinity. During the activation process the agent said they received an error code that the serial number already exists. Error code [] [].(!{2}!) This unit was brand new. How do I get around this?

My SB8200 had been working fine for more than a year and a half, but this morning, it went catatonic.  Front panel lights were all still good, but the (separate) router could no longer see it.  The router itself seemed fine.  Rebooting the router made no difference.  Rebooting the modem re-established the connection and everything was fine. About an hour later, the modem went catatonic again.  Another reboot, and everything was fine.  This time I tried to log into the modem to see if there was any useful information in the event log.  It told me my username or password was incorrect, which is highly unlikely since I use a password manager.  After multiple attempts to log in, I had to use the last 8 characters of the serial number as the password.  That worked, and I’ve reset the password. The event log had no useful information, but I noticed the time of the most recent event was more than an hour earlier--before the most recent reboot!  I checked the sta

Greetings and salutations — I have two Arris modems — an SB8200 with WOW/RCN/Astound service and a T25 with Comcast/Xfinity service connected to a router.  The router has multi-pathing enabled and balances remote destination addresses across the two WAN connections.  Under normal circumstances, this works well.  If Comcast’s service fails, the T25 blinks out, the router removes it as a routing option, and life goes on.  BUT, if WOW service goes out, the SB8200 doesn’t blink out with it — instead it switches from being a bridge to WOW’s network to being a gateway to nowhere.  It leases my router a new address from its built-in pool and carries on.  This is an incredibly annoying behavior because it results in external addresses being balanced between the remaining WAN connection (Comcast) and a black hole (WOW.)  Devices on my internal network can get to e.g. ibm.com but not e.g. google.com.  Is there a way to force the SB8200 to function as a bridge when it looses sign

So I am only getting the download link to light up setting up this modem on Xfinity no upload and no internet this is out of box have tried reboot a few times 

Bought what says SB8200 on the box at BestBuy.  Registered modem with SURFBoard Central by scanning the S/N during modem activation. Says in the device here it’s a SB6141?

Wi-Fi will drop several times a day on phone at home. I was told that it was because my Arris modem hadn’t been updated. It is 2 years old. Does it update automatically or do I have to do it?
