surfboard SBG8300- unable to login the GUI web portal

I reset the router. I want to create a username and password and access it. I’m able to connect to it with my laptop and it goes directly to login screen asking for my email and password. I’m not able  to get past this screen. I appreciate any suggestions.  btw, I’m using two different Surfboard routers in two locations. Can I control them both from the app?

ARRIS Surfboard SBG8300-RB no internet access

No connectivity issues until a big storm rolled through. My Alexa alarm went off in the morning and I couldn’t turn it off by talking to it so I went over to unplug and noticed it had no internet connection. When I got home later that day still no internet. I unplugged it for 30 seconds, nothing. Then again for 2 minutes and nothing. I noticed the lights never blinked or changed colors. They both are solid blue when plugged in, off when unplugged then right back to solid blue as soon as I plug it back in. I tried doing a hard reset and it won’t even respond to me pushing the reset button for 10 seconds or 30 seconds. Any ideas or suggestions appreciated!

Unable to Add Device from surfboard app in Parental Controls - SBG8300

I am trying to set up Parental Controls through the SURFBoard Central App on my SBG8300. In My Experiences tab I have created a User Profile under Parental Control and when I move to +Add Device I see a selection of devices I can select.  When I select a device and click ADD DEVICE at the bottom it spools for a while and then clears the page, not adding the device.  It does this with every device on the list.  I cannot add any devices as it spools and then clears ever time.  Why is it spooling and what can I do to get a device added to the User Profile?

SBG8300 won’t connect to online and led light is flashing

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?

SBG8300 Not Broadcasting 2.4GHz band

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 password Guest 2.4 wifi also did not broadcast; default or cu

Light indicators on SurfBoard SBG8300

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.

Is my computer's wrong location due to my modem (SBG8300)

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

SBG8300 - How to change the modem name and password

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 connect wifi extender to new surfboard SBG8300

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??

arris sbg8300 disconnect every 48 hours

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?

SBG8300 remote management

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.

SBG8300 no longer works with xFinity

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?

SG8300 not accepting captcha codes on the settings page.

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.

SBG8300 - connected devices are not listed on SBC app.

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