SBG8300

ISP did update last night. Modem green light blinks slow than fast then turns blue. How to fix?

I lose the 2.4 GHz only runs on two items 5 GHz runs on all other TV laptop. No problems have to reset modem. At least once every three days any help modem is only a year old

Howdy,      I use FileZilla for work and I work remotely. My company and internet provider cannot help me. Any ideas what could be blocking access? I’m using the Surfboard SBG8300.     All FileZilla says is Connecting to < SERVER NAME >, then < Connection timed out after 20 seconds of inactivity > followed by < Could not connect to server >     However, if I change my wifi to my iPhone Personal Hotspot, it connects very fast so I know my credentials are correct.      I hope you can help, I’ve been struggling with this (off and on) for over a year.Later

What android app do I need for the SBG8300?

I have noticed a trend with surfboard modem router internet output ports failure. This is my 2nd modem over last 3-4 years. I had same issues with previous modem . I purchased SBG8300 last year. It has 4 internet output ports. Initially first output port failed. Now all 4 ports failed. I called customer service but call doesn’t go through. I am very disappointed.   

The warrantee on my SBG8300 expired in October, and in November, so did the unit itself (both leds solid blue instantly on power up, no appearent boot sequence, no WiFi signal, no change after pressing reset button). Is it worthwhile to try to get this unit repaired?

Is it common problem with surfboard modem with ethernet ports? I have purchased SBG8300 in 2024 and put in service in May-2026. Initially 2 ethernet ports quit working and I switched my ethernet to a working port. Last week remaining 2 ports quit working. Wi-Fi is working as normal. I have my internet service with Xfinity. I am thinking to call Xfinity to ship their own modem to get rid of SBG8300. I have lost a quite a bit of money on SGB8300. Very disappointed.   

I previously used the web to login in to my SBG8300 Device Manager, but receive an error number 0000-1900 that my Chrome browser version is out of date every time I log in, yet the version on the error message is an old one.  I also receive the same error message if I log into the Device Manager using the Edge browser. I downloaded the new Surfboard Central app, but when I click “Network”, the page goes through the endless refresh cycle, circling and circling and circling…..How is this resolved so I can manage my modem/router gateway on the app?

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.

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

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 ?

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
