SBG8300

When I try to login using the credentials identified it is not allowing me in.  I cannot reset the modem because it was DIFFICULT adding devices to the 2.4 band.  How can I find the correct password for 192.168.0.1? I also have been having difficulty adding the Chamberlain My-Q garage opener to the 2.4 bandwidth.  Do you have any suggestions for this issue?

SBG8300 connected to LAN, and I get internet with wired connections, but no internet via wireless connections.  Reboot doesn’t help for long.  Factory reset doesn’t either.  Have I got a defective unit?

I just noticed my new SBG8300 has a setting on Ethernet port 4 to turn on “WAN over Ethernet.”  Does this mean I could connect this to a second router (elsewhere in the house) and connect to it as a separate network with internet connection?

I am having issues connecting to the internet with my new SGB8300 modem.  Service is through Cox and they confirmed that they are seeing the modem and everything on their end is connected.  I am unable to get connected via both wifi and LAN line.  The error is connected but no internet.  I have restarted/reset the modem several times with no avail. Any help would be greatly appreciated on how to get connected to the internet.

Top light is slow blue flash. Bottom light solid green. Cox says they can not see the modem. 

Hey all, Am I able to use Nord VPN on the 8300?I've been searching but cannot find a definite answer. If it does work,how do I set it up(link)?Thanx!

I set up some port forwarding rules but I am unable to view what is set up on the router. After setting up a port forward rule Port forward screenHow can I get the port forwarding rules to show on screen? Using google chrome and safari.

I bought an 8300 so I could turn in our Comcast rental wifi modem. I selected the 8300 in part because it advertised the highest square foot coverage. We have a basic Xfinity plan - 75 Mb, and that has always been plenty (It was plenty for us at 25 and 50, back in the days when those were the basic plan data rates)The 8300 has so far been much less reliable, especially for my older Win7 laptop, which won’t connect at all despite 3 bars and 30 foot distance - almost line of sight location...my laptop connects only to our extender for the kids rooms down a hall, and that only intermittently. Out of curiosity I tried configuring the 8300’s guest network for 2.4G - still no joy.I turned on WiFi band steering and that somewhat helped, allowing me to connect but still only via the extender.Ideas anyone? 

As the title states, I received my SBG8300 modem/router two days ago. I immediately noticed that the 2.4 Wifi kept disappearing, and I lost connection. I’ve factory reset the modem, and the problem persists, and now my Alexa and Smart Life app is failing to connect since it requires 2.4 wifi. The website shows it is active.This is one of many problems I have experienced. I could use the web but not the mobile app, as it wouldn’t connect. Now I can use the mobile app, but the web won’t connect.Is this a product defect?Update: I got the Alexa and Web working. I’m still experiencing 2.4 wifi dropping while the app and web state it is online.

I recently installed an Arris SGB8300. Prior to installing, I almost never had issues with audio during my meetings. Now, the audio frequently cuts out for about 3-5 seconds. I can still see peoples’ mouths moving and the live captions pick up what they are saying but I cannot hear it. During meetings, I am connected to the 5Ghz network. I have Breezeline/Atlantic Broadband for an ISP. Here’s what I’ve tried:--reset gateway--connect to ethernet--turned off guest networks--audio with multiple sets of headphones (corded and wireless) and straight from computer speakers--happens in both Teams and Zoom calls, also happens when private listening to Roku streaming--run speed tests (very fast internet) and wifi analyzers--manually changed network channelThe only thing that has fixed it without fail is switching to my phone’s hot spot, so I am pretty certain it is the gateway. Is there a setting I should be looking for that I am missin

I just purchased my new Modem model SBG8300. I have Xfinity speeds up to 800mbps and upload speed of 200mbps. But with this modem I get 300mbps download and like 10mbps upload.  Any help or advice?

I have an SBG8300 modem/router connected to Comcast/Xfinity Cable.I bought it from BestBuy last month, and it was working completely fine in the first few days (around 5 days). However, it periodically loses internet connection about every 2-4 days, and I have to unplug and plug back the modem each time to restore the connection. I called the ISP customer service, and they said they had updated the settings, but the same scenario kept happening afterward.Is there any possible reason for this? The WAN status when the internet is not working is similar to the one when the internet is working.

Installed an SBG8300. WiFi works fine, but Ethernet doesn’t list as an available network.

Bought a used SBG 8300.  Modem works except wifi was setup by previous user and I do not have the password.   I tried to reset the modem by pressing the reset button more than 5 seconds however the modem would not revert back to factory settings after the reset.   What are my options?

Hello -- Optimum provisioning is not updating the WAN IP address properly to get out to the internet -- still showing the internal WAN IP address so can’t get out to the internet.  I can get the WIFI set up so it’s got have something to do with proxy or security or some setting within the admin portal.  They want to send out a technician at $60 for service call.  I don’t want to go there if someone knows what setting I should be updating to make it provision properly…..Any help is appreciated!!!

I now have AT&T fiber optic using their modem/router in my house. Previously I had Comcast cable and used my Arris SBG8300 for WiFi.  I have a Cat5 cable running from my house to my detached garage which I used in the past plugged into my Arris Model SBG8300 (house) when I had Comcast Cable. The Cat5 cable was plugged into a laptop I used in the garage. My question is, can I plug my Arris into the Cat 5 cable in my garage, connected to my AT&T Router/Modem (house) and use it for Wi-Fi for some remote security cameras in my garage?

I have been trying for the better part of an hour to log in to surfboard manager and it won’t let me create an account.  I put in my email address and the first ten times it said that it couldn’t find my email address, then it finally prompted me to create an account. I put in my email address and name and created a password and it keeps saying to enter a correct new password and it won’t allow me to get past that.  Help

I recently got a SBG8300. I registered it with my ISP, Cox, and set it up. The solid green led indicator is on and I verified through the admin page that it was assigned an IP. However, the modem doesn’t seem to be able to access the internet. Both Ethernet and the onboard router aren’t able to provide internet access
