SBG8300

I have an ARRIS SBG8300. I have an issue where the Ethernet and WiFi both lose internet connection or is slows down to around 2 mbps download speed. The problem is intermittent and started a few months ago. I have had Spectrum out 3 times now and they claim nothing is wrong with my service. I tried swapping out modems and it didn't fix the issue. Today, my I ternet went out but none of my neighbors lost connection. I noticed that the Wifi light was completely out and the internet light was solid green. I had no internet on Ethernet or WiFi though. Does anyone know what the light combination means or have any ideas on how to fix my issue? 

The web admin panel warns “To keep your account password in sync, it is recommended to update it using the SURFboard App rather than changing it here.” How do i change the admin password from the app? I looked absolutely everywhere and the option is nowhere. I changed wifi names and passwords and settings from the web interface, nothing synced to the app, now i’m locked out at the app. The app doesnt let you change the admin password, and the web interface syncs nothing to the app, what do i do?

Good afternoon! I have been trying to get support to my SBG8300 and when I try to chat or call it wants to check warranty but it says the serial number doesn’t match the model. I do have the item on my hand and it does never work. Could somebody please help me getting this fixed?

My Internet connection stopped! Please connect my internet! Help

I recently had a power outage do to an animal getting on the power lines. While all my appliances got power, my modem only had the online light on blue solid and no wifi light. I called my ISP thinking it might need to be re provisioned and they couldn't detect the device. I tried resetting it, restarting it, connecting on different ports and nothing.I cant access the gateway via ethernet. I think it might be fried and need a new one if not please let me know what I can do

My wi-fi stopped working a few days ago and I now see that my Arris modem has been RESET to factory settings out of the blue and I do not have the original password in order to reconfigure it to my settings. 

ive tried too access my user interface but no luck. it says i have an unsupported browser so i downgraded to the minimum it asks for and still no luck. i know my credentials are correct when login but its not letting me login. i havent changed the password infact ive never been able to login at any point. 

SBG8300 been working okay… but noticed the 2.4Ghz SSID might appear, and might not appear.If I reboot the SBG8300 after a while it might appear for a few seconds on SSID list, then go away.If you connect a hardwire and login to admin page you can see that the Broadcast SSID is set to Broadcast. There are SO MANY posts on this exact topic hard to keep track, and the answers are all pretty poor. Answers like do a hard reset on the modem, which I would have to do and reconfigure monthly - not  a good answer. Or the answer to go in and set it to Broadcast. That one came from a NewBie just trying to rack up points. Why are SO MANY SBG8300 failing to broadcast the SSID for the 2Ghz band ? Sounds like a firmware problem to me. And I own this, so it is not monitored or updated by my ISP. Alike others here, my smart home Iot devices all stopped working when this problem started. 

I have an Arris Surfboard SBG8300 and the blue online button is blinking as well as the green WiFi button is also blinking. My WiFi is not working and I’ve unplugged it for 30s and did a factory reset and nothing is working. What should I do?

no internet connection 

I do not currently have my surfboard. Modem router combo connected because it was getting us very slow speeds, but when it was connected, it would show that it was connected from our device to the router modem, but there would be a big x going from the modem to the outside connection. We would still have internet, but it would always be slow.  How do I fix that problem? Thanks much.   Pat

I purchased my SBG8300 March 3, 2025, and it has stopped working. I know it is the modem because the issue I was having is gone now that I have borrowed a different modem. How do I input a warranty claim to get a refund for the modem?

Trying Trying to activate And App stops at Registering Have already called shentel And the unit is active there but I can't get it on my end

How can I change my password for my log in information?  I can’t seem to remember my password to get into my Arris surfboard account to see my router settings. 

Modem admin still cannot be reached, even on Safari… and it’s now 2025. What is going on?

Is there a secret to clearing / releasing all clients previously connected to my SBG8300?I have performed a factory reset before, however everything previously connected reappears in the connected client list. I want to make sure that I have no Rogue clients connected without my knowledge.Thanks in Advance

Today I called Arris Surfboard Tech Support to inquire about updates for my SBG8300. The agent’s false and totally untrue answer:  “Your Internet Provider provides updates for your Surfboard modem”. Thus insinuating that I am an ignorant buffoon, which I plan to deal with later.Question: How do I receive software updates for my modem?

I downloaded the Surboard app and try to register but I was never given the chance to create a password. When I try to access the 192.168.0.1 it asks for an email and password. How do I create a password so I can access the settings in my modem/router? Thanks.

I have a wifi system based on an Arris SBG8300. My Open Sprinkler (running a Raspberry Pi, I think) has a controller that connects to the routher encode to use a url of 192.168.4.1 It fails to connect. (times out). I presume this is a setting on the rother that rejects addresses like this. Suggestins? 

Can you please tell me how to log in to the Arris SBG 8300. I got it about a year ago and never set up an account and want to locate the devices that are connected to it and change the password. 

no me acuerdo la contraseña del app de mi mordem y dicen que van a enviar un cosigo a mi @mail y no me lo envian que dwbo hacer

I have a SBG8300 and am having connectivity issues.  My local internet provider said everything was good on their end suggested I call ARRIS to see if there is a problem with this device.  Can you assist

I’m about to purchase a refurbished SBG8300-RB from Amazon. What is the warranty for a refurbished product?

I have owned a T25 router in Texas for about 4 years now and it has worked flawlessly for the entire time I’ve owned it.  However, a new problem has popped up.I purchased a wifi enabled pellet smoker made by Recteq.  The smoker will not connect to my router.  I have reached out to Recteq’s technical support half a dozen times and they cannot resolve it.  What they are telling me is that something with the router is preventing the smoker from connecting (they confirmed this when the smoker will attach to my secondary cell phone’s hotspot).They informed me that there is something with the router blocking the smoker from connecting.  I have gone into my router dashboard via the IP address and have confirmed that the “blocked list” button is turned off (and even if it was on, there are no devices or addresses in the list).  I have also lowered my firewall protection to the lowest setting allowed.  The smoker simply won’t connect.Does anyone have an idea why this mig

I have a SBG8300 on my first floor; the home is 3 floors/2700 sqft - the coverage inside the home is solid but if I step out to the deck the signal is very weak. Want to add a Wi-Fi extender on the 3rd floor to improve connection/coverage but not sure what model/brand is compatible with my SBG8300.   Note: don’t think adding a mesh is possible, don’t have cable/Cat5 on third floor.
