SBG8300

I’m having trouble getting my router restarted. It stopped working today (blue light was flashing) so I did a hard reset according to what I found from arris online. It now won’t stop blinking blue which I think means the IP isn’t connected? I’ve tried resetting again but that still isn’t helping. Do I just need a new router?

I have a SBG8300 with a customized 5GHz and 2.4GHz band. My ISP is Sparklight and I am located in Arizona USA.The 5GHz band shows up on all my devices, but I can’t see the 2.4GHz band. I have tried multiple tablets, mobile phones, laptops, and my desktop computer. None of the devices can detect the 2.4GHz band.My internet speed is over 300mps upload and download (though I don’t think that would have any effect on the band broadcasting) and the 5GHz band connects perfectly to compatible devices. 2.4GHz is nowhere to be seen. I did use band steering previously, but we recently got a few devices that only use 2.4GHz. I turned off band steering and the 2.4GHz band isn’t detected by any device in any location inside or outside my house.I did everything I can think of to troubleshoot and nothing has worked.Two factory resets (each of these settings tried on each reset) Default 2.4GHz band and a custom 2.4GHz band with new SSID and p

It appears I have a connection with solid green lights on front. Back light by ports is amber and blinking. We have normal internet service so assuming there is an issue with the router. I would like to know if there is a fix for this as none of our devices are working and cannot connect. 

So, in short, my desktop and laptop both think I’m located in Canada, but I’m actually in Pennsylvania. This has become a real pain when it comes to streaming and other websites requiring location info.I’ve tried to eliminate all other possible sources of the problem. I don’t have a VPN, and it doesn’t seem to be a software issue. I’ve spoken to support at Xfinity, Windows, and Google, and none of them can figure out the issue.I think it may be my SBG8300 modem, because I’ve taken my laptop to a relative’s house who has the exact same type of Xfinity internet, and lives only 15 minutes away, and when I connect to their wifi (without changing anything on my laptop), suddenly my location info is correct.I’ve also restored my modem to factory settings and still the issue persists. Any help in figuring this out will be very much appreciated! Thanks

Hi, I have a new Surfboard sbg8300 modem. I have 20 renters who regularly connect to it. Rather than have to tell everyone the new modem name and password I’d love to be able to set it to what it used to be. How do I do so?

How do I get the max download and upload speed out of my SBG8300

Should Wi-Fi light be blinking on modem when connected

When connecting the device the blue and green lights both blink slowly and they never turn solid green

Internet went out during a storm and now won’t reconnect  IP provider is Optimim I have reset a number of times. Spoke with Optimum and they said the signal is fine. The light are flashing blue for Internet and green for WiFi.  I can connect to the WiFi but still not Internet access. help please.  

We have a previous wifi extender - TP Link that was easy to connect on our old router/modem as the old one had a button to connect it. This new surfboard does not. How do I connect this wifi extender now??

I have an Arris SBG8300. What make and model extender should I buy?

I bought a new arris sbg8300 modem. When using it every 48 hours it disconnects the internet the light is still green and I have to unplug and plug the modem back to work again. It disconnects exactly same time all the time. I was thinking because on my arris app there is zero my devices connected, it thinks nothing is on so it stop connecting. I can’t add any devices on the app because are no choices to add my devices. When logging on arris on my computer it show what is connected. I rest the modem and that didn’t work. Any idea?

I have connected multiple devices to the Modem/Router combo that I bought recently. But the app is showing 0 devices connected. Is there anything I am missing to setup?

How can I remote manage my SBG8300?  It’s in router mode and the only way I can reach it is via directly plugging into the back panel. I can access it over the WAN on the public IP nor via the LAN on the same IP.   Even the Arris app on my phone fails to find it.

As with other posts, I am reporting the same now. I’ve had the modem working fine for almost 3 years and suddenly, it stopped working correctly.  As I am technical, I looked at everything and noticed it was no longer receiving a WAN IP, therefore, either the DHCP functionality on the modem is failing or DHCP server at XFinitity is having issues.  Talking to Xfinity support is a waste of time because they are Tier 1 ppl and only run Layer 1 tests.If I reboot it, it sometimes works, sometimes not. When it does work, I may be good for less than 24 hrs before it starts acting up again.I almost feel like this is some sort of scam to get people to rent their modems.Is there any troubleshooting I could do regarding the DHCP issue? Packet captures?

SBG8300, the 2.4ghz network is not visible to devices. Admin page says it's online. Have rebooted several times without luck. Have not factory reset yet. Any recommendations, ideas?

I checked the warranty of my SBG8300 and it says it is expired. How can that be when it hasn’t been activated yet? When does the warranty period start?

I'm trying to raise the firewall security level and the captcha codes I enter are not being accepted so that the router will let me save the new settings. It just keeps feeding me new ones. Some are hard some are easy. I’ve tried upper case, lower case, spaces between characters. Nope. I’m probably up to 30+ attempts now.

Is my SBG8300 compatible with Windows 11?

I just recently purchased SBG8300 i am connected to the internet on it. However, i cannot get into the modem settings to set the rest up. Neither the mobile app nor the internet page will accept the admin and password defaults. any help would be appreciated!

When I open the surfboard central app it shows zero devices connected.  I know this not to be true because every thing is connected.

I setup WiFi MAC filtering on my SBG8300 when I got it a year ago. I manually added my device MAC’s and set to Allow. From what I understand, it should only allow those listed devices to connect to my WiFi with WiFi password and no other devices should be able to connect even with correct password. I discovered that devices not on the allow list are able to connect with the password. I tried setting the list to Deny, save settings, my device MAC’s in the now Deny list could still connect to Wifi. I have had the guest networks disabled since I got it. So the MAC filtering feature seems to be not working at all no matter how its set. Is there another setting somewhere that could be conflicting? I would rather not do factory reset, takes long time to setup this router and can’t save config. 

My internet provider can not make my internet connection work until (hopefully) Monday (today is Friday). When I try to login to the SBG300 using either Chrome or Edge at address 192.168.0.1, I am told that it is an “insecure connection” and it tries to re-route me through an remote internet page.  Of course this fails because I have no internet connection !I would like to configure the WiFi and Router without the internet connection BEFORE MONDAY !Is this possible.I have rebooted and reset the modem multiple time.  Don’t waste your keystrokes telling me to do this again !
