SBG8300

Hello, we have a SBG8300.I got a new phone and the surfboard central app has me starting over with set up, but it claims it doesn't support my model and directs me to the other surfboard app. The other surfboard apps needs a log in, and I can only get that log in info from the central app that I'm forced to restart set up on. Unsure how to proceed. We can still use our Wi-Fi, but I have no way to get in there to change or update anything

All of the devices on my sbg8300 network are showing up on the arris web interface but only 1 device is showing up on surfboard central app on my iphone 13 pro. I tried uninstalling the app, rebooting the sbg8300, and then reinstalling the app. I also tried the factory reset of the sbg8300.

In my area, Spectrum just upgrade their cable to “symmetrical” (sometimes called “full duplex”) signaling.  Even though they list the SBG8300 as a supported product, they basically said “tough”. Is there a firmware upgrade available that will make the the SBG8300 work on a symmetrical network ?

  Please help me with my ISSUES getting into modem softwareI have an Arris SGB8300 and use microsoft edge browser.I changed my admin password to the router/modem.I logged in successfully to 192.168.0.1→ I was warned my Edge Browser was unsecure→ I was to use 70.0.3538.110 (later tried and got …  (similar message as one shown)I then attempted to forward a port (found where - but had extra fields to fill in)I logged outWhen I wanted to log back to router … I got the HMMM … Can’t reach this page TAUNT)I think it is my machine blocking … but IDK..

I'm trying to port forward to set up a zomboid server with my friends but every time i add the ports i get an “Operation Failed” error. I have the correct UDP ports and all just when activated i get that error every time and I’m not sure what i could do to fix this. Any help would be greatly appreciated.

So. Got my SBG8300. Need to port forward on it.This page https://arris.my.salesforce-sites.com/consumers/kA5Qi0000003RuiKAE says you use the web portal. Great, it needs a password I don’t have. Now this page: https://arris.my.salesforce-sites.com/consumers/articles/knowledge/SBG8300-Web-Manager-First-Time-Login says there was a redirect page. Great, that never happened. Now this topic right here:  says it’s the same as the app. Except the app doesn’t have a password. I tap logout, I tap login, I’m logged in. No password.So

I keep getting an error that the model and SN do not match

Been using my Surfboard SBG8300 modem and router for 4-5 years with no issue. Over night, the modem-router stopped allowing a connection to the internet. Both lights on the surfboard are solid green. I have no problem accessing the admin panel. When I go into the admin panel, it notes that WAN internet is inactive.  Tried restarting, power cycling and a full factory reset.  ISP is Optimum and we have a 500mb plan. ISP said it is likely an issue with the modem-router and it will likely need to be replaced, but is sending out a tech tomorrow. Any other troubleshooting I can do/any thoughts on what might be the issue? 

Is there a software or firmware update?  my Xfinita speed is high but download speeds are low, where in the Arris site do i fine or manage my divice?

All of a sudden I am unable to access the website (because it times out) for my email.  I had no problem since I had the SBG8300 which I bought July 2023 until a couple days ago.  The website for my email provider PA.NET is webmail.pa.net.  After I installed a VPN (Nord VPN) I can access the website.  Comcast is my internet provider.  I checked with them and they saw no problems.  I checked with PA.NET and they could not find any problem.  I can get my email using comcast as a internet provider with no problem. I can get the email using Verizon on my cell phone when using only Verizon as the provider.  When I use comcast through the SBG8300 on my cell phone the email times out.  I use wireless WIFI.  I tried hooking the computer directly to the SBG8300 and still had the same problem.  I have tried 3 different computer and they all had the same problem.The only thing common with this problem is the SBG8300.I would appreciate if you could help me find a sol

I have a flashing blue light and a solid green wifi light on SBG8300. What does that mean abd how do I fix it? I already recycled power a few times, used reset button a few times, and replaced coax cable. Also called ISP and they said no problems on their end.

1 surfboard app not working2 can’t find out if my wi-fi modem is under warranty for tech support because it won’t recognize the serial number3 the “premium” tech support number hangs up every time4 can’t find the answer in the communityI tried to use the surfboard app and there is no log in it just says get started and every path I go with the get started there is a problem. This is the worst experience i have ever had trying to get help with something

I lost the owners manual for my SBG8300, where can I get another one?

No internet- Solid blue lights for online & WiFi. ISP came to house confirmed strong signals on all lines. I Factory reset the modem and lights never changed. Plugged into different outlet, same. Can not connect to internet, any assistance would be appreciated :) 

Modem has strong  signal but still not connecting. Cable company checked all wires and inputs and signal is strong. Blue stable light on for online & WiFi. Cable company also did factory reset, still not connecting to internet. Please help so I can trouble shoot as I work from home. thank you 

I currently run a SBG8300, and I wanted to add some more range to my network.  I purchased a combo that come with an A21 and W11.  I tried using the app, but when I go through all the screens to log in after saying I’m already activated, I get an error code of 0000-1612.  Any way I can get around this?I can connect to the modem with a desktop using the 192.168 etc, but I can’t find anywhere to add the A21.  

Yes i am having an issue accessing one certain website. I was able to access it last week no issues, and over the weekend something must have changed because it only gives a ERR_CONNECTION_TIMED_OUT. I have tried multiple browsers/computers/Ethernet and wifi/flushed dns/releaseandrenew ip.The only time i can get access it from home is then i am on my phones 5g, as soon as i switch over to  my network i can no longer access it. I have called my ISP and they said they can not help because it is not there equipment, and this issue has to be with the Modem and company

is it possible to get a firmware update for this modem?

First of all I can not get the App to work what so ever so I was trying to log into the Web Manager to change network name and password. I am able to connect to the Wi-fi with the default network name and password but want to change it. When I try to log in Web Manager, I use the username: admin and the password that is the default password on the sticker. I also just tried the work password as my password since that is what it says in the little book that came with it. Every time I get invalid login credentials. What am I missing here? 

I installed my sbg8300, and called Mediacom (less than 1gig service). They state that they can see my modem, but I have no internet. All the settings look good on my sbg8300 interface, but I did a factory reset on the modem anyway. I've tried with two different computers connected via ethernet. I still have no internet.

Can I reboot my SBG 8300 modem router combo remotely?

I unplugged my modem and disconnected the coaxial cable and Ethernet cable from my modem.  I plugged my modem back in with the coaxial cable only.  It’s in the same location as before.  Now it keeps dropping the internet.  It’ll be on for 5 min, the no connection, then back on…..I did a reset by unplugging it as well as poking the little hole on the back.  Nothing fixes the problemSusan 

I have an Arris Surfboard SBG8300.  I’ve recently started having issues with it rebooting intermittently.  I was attempitng to gather logs.  I go under Troubleshooting and Logs, but when I query for System or Event logs, it states “There are no logs to display”.  I don’t see where I can check to see if logging is turned on or not.  How do I get logging on my device.  Seems like firewall logs are working just fine.
