SBG8300

I’m considering purchasing the ARRIS SBG8300 modem/router, because I need to buy one with DOCSIS 3.1, and need to know if I can use a DECO Mesh Wi-Fi system with it?  I also need one with as many ethernet connections as possible, and this model has 4. I currently am using the ARRIS SVG2482AC, which has 4 ethernet outputs and it is DOCSIS 3.0, and my ISP say that I need to upgrade to 3.1.Thank you

Just got the SBG8300 model which has the same password for 2.4GHz and 5GHz networks. On my phone, two wifi names come up: “Guest” and “5G” type. The “Guest” network is connected using the default given password; however, when trying to connect to the 5G, it says “wrong password”. 

Can the Arris surfboard sbg8300 set a limit of upload amount.  Limit to 2GB per 24 hrs.?

We just bought and hooked up a SBG8300. It seems like the range is terrible. We’re trying to hook up our Ring cameras around our yard, which worked fine before, and they keep disconnecting and saying they have no signal. Is it the range, or is there something else going on with it? Ideas?

I bought an SBG8300 to replace the cable provider modem.  I also have an eero wifi network.  I started having issues and was advised to place the 8300 in bridge mode.  I did that and all hell broke loose as my eero network was no longer recognized.  I had to disable bridge mode on the router before things started working again.  Any thoughts would greatly be appreciated

For whatever reason my refurbished SGB8300 will not recognize the login password. I know it’s correct because I logged in every device in the house myself and now it won’t recognize it. I also cannot log into the admin page to reset things myself.So my thought is to hit the re-start button, lol. I just have no idea where te booklet that came with the unit is or if the reset will go to the “factory” settings or a “refurbished setting”. I was trying to chat with customer support but they wouldn’t recognize my unit, I guess a refurbished unit isn’t worthy of their attention. Any help is appreciated, Ed

I have followed all the instructions I can find on these boards and I contacted my ISP and they support the SBG 8300 and firmware is updated. I’m still having trouble getting wifi at 2.4Ghz. Nothing is connected, so there is no congestion. I’ve endabled/disabled and restarted mutliple times. I did a reset of the entire wifi on the modem.  All without any luck. The 2.4ghz will appear briefly and then after a couple of seconds disappear. 

I have a surfboard 8300. My main 2.4 ghz WiFi is not working but the guest one is. However only certain things will connect to the guest WiFi and some things won’t. When I try to log onto the web manager on 192.168.0.1 it says the server can’t be found. What setting got changed or corrupted?

I'm getting an error entering in the IP address using chrome.  Says my credentials are wrong and I'm using the wrong web browser.  

Just installed. How to change name and password to match my existing network which all of my devices connect to.  When I connect to my previous network, no internet

I’m trying to change my nat type using the ip from my router but cannot log in. I've tried the wifi password, "password" and the password on the actual router but nothing works on the admin login page

This is a new issue within the last few days, and was not an issue a week ago when using the router for the first time.When PC is connected to (and using) ethernet, and either the 2.4g or 5g Wifi channels are active, the modem eventually (within minutes) shuts off completely, forcing me to disconnect power and reconnect to reboot. When a device or multiple devices are using the Wifi channels, and no PC is using ethernet, things seemingly work fine.When PC is connected to (and using) ethernet while Wifi channels are disabled, things seemingly work fine.Repeated critical logs include: 72001011-DHCPv6 - Missing Required Option 2472001011-DHCPv6 - Missing Required Option 8272001004-DHCPv6 Provision - 0 Retries Attempted with Last attempt at Wed Nov 13 20:16:27 202472001015-DHCPv6 Failed - No Prefix Available72001014-DHCPv6 Failed - No Address AvailableAll Down/Upstream QAM Power levels and SNR readings look within nor

After a brief power outage i have no internet. Both lights are green. I have reset the modem and confirmed with Xfinity it's activated and they can see it.

I upgraded my Comcast / Xfinity speed to 1000 GBPS but my speed test only shows up to 313MBPS. I tried and got the same result when tethered on WAN and on WIFI  I’ve tried restarting the modem and router both from Xfinity’s app and power cycling the modem / router. Still no change. I called Comcast/Xfinity and they said I need to lease their latest router / modem for $15/month. Is there no other way to get close to the 1 GBPS speed that I paid for?

Hi,I have sbg8300 modem.  It suddenly drops connection intermittently.  Internet provider tech said signal is strong.  Is there anything I can do to troubleshoot?  Internet provider is Starlight.   

I have a SBG8300-9D65 and I have agreement with Xfinity for 1Gbps, so I should expect at least 800Mbps but I’m getting less than 100Mbps.This used to work well always over 650Mbps… suddenly I’m having this slow speed.Xfinity tech came to my home and tested the cable from the outside connection box to the connector inside my home, he said it is good, up to 1.4Gbps…My modem is on warranty until March 2025.Should I request a RMA? or there is a tech support for troubleshooting?Any firmware update that I could apply? and how?   

My modem goes on & off, doesn't work consistently and been a pain dealing with Cox. Now I have a Cox unit testing it and it's certainly my Arris surfboard that's the problem. I just got it last year certainly must not be faulty. Help!

Only one of 20+ devices show online on the app

Does Arris offer a range extender compatible with the SBG 8300 or G54 modem-routers?

For the last couple months (roughly 6 or so) my (refurbished) SBG8300 has been randomly rebooting. Sometimes it’s 2pm, sometimes it’s 10pm, on any given day. It’ll  stay up for maybe 4-6 days and then all of the sudden reboot. I can confirm this is what’s happening because the uptime timer restarts. My internet will drop and then my router will have the solid blue light on the internet icon. The reboot takes 5-10 minutes to complete and then it’s back on like nothing ever happened. The device is already connected to a UPS and no other devices connected to it have ever had any power issues. My ISP is Xfinity (unfortunately no other options) and they’ve confirmed everything looks good on their end. We’ve done the whole song and dance of rebooting the signals and my router multiple times but it doesn’t change anything.I’ve been having this issue with this router for at least the last 6 months and have just been dealing with it since I’m no longer under warrant

I recently installed an SBG3800.  The Surfboard Web Manager only shows 9 connected devices; the Surfboard Central iOS app shows 0 connections.  I can see all 12 connections on the Fing app.  I have tried restarting the modem. Hardware Revision: 6Software Image Name:AR01.02.078.04_092820_711.NCS.10Firmware Version:01.02.078.04.NCSRDK-B-LLC:rdkb-20171127SDK:7.1Wi-Fi Driver:4.7.23.30.4.0

I was having connection issues on my Arris SBG8300 using 5G. I enabled band steering, and now the 5G channel doesn't even show up as an option. 

No Port Forwarding 

Xfinity just  sent me an email stating that my Arris SBG8300 modem will not deliver 1.2 Gbps which is the speed provided by their network. My speed check comes to 868.5 Mbps and I am CAt6 hard wired to the modem approximatly 20 feet away.Can anyone on  this form collaborate this info? And if so, does Arris have any suggestions to remedy this problem? Software upgrade?

i cant access the admin login. i used the default login after i reset the router and still cant get in. it does say im using an unsupported version of chrome but mine in is updated and because of that the browser is unsecure. I've tried adjusting every security setting and even downloading an older version of chrome but nothing has worked. i could use some help if anyone has any ideas
