arris sbg8300 intermittent internet connection

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?

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!

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 - 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?

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.

SBG8300 MAC Filtering Not Working

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.

Login to modem/router through INSECURE connection SBG8300

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 !

Unique Connectivity Challenge - Help sbg8300

Hi All,I have a Surfboard SBG8300 with WiFi enabled. WiFi is bad in other areas of the property.  Here is the challenge.i have quite a large property:SBG8300 is installed in a thermally controlled AV Room with A LOT of other equipment.All SBG8300 switch ports are in use 3 go to separate Cisco 28 port Switches to flood Ethernet across the property, the last Switch port connect to a Security NVR directly.i need to improve the WiFi signal from the SBG8300 to other areas of the property. I’m not sure if I should use the ARRIS SURFBOARD mAX 6e Mesh units maybe 2 or 4  and connect their Wan Ports back to the Cisco 28 port switches or do this some other way..I tried to do this with Apple Extreme Routers and put those in Bridge mode just to extend the 8300 WiFi but it causes me nothing but problems so right now those are paper weights. Looking for community guidance here. Thanks.

SBG8300 Lost connection

I have Xfinity internet in PA and tonight at the same time, everything lost connection to the internet. My devices could still connect to the modem, but could not access internet. It has been raining, so I figured there must have been an xfinity outage. After reaching out, (and of course restarting the modem multiple times) they confirmed that there were no issues on their end and they were able to send “refresh signals” to my modem, but it still could not access internet. I upgraded about a year and a half ago and I still had my SBG10 laying around. So, while talking to xfinity customer support, I was able to activate that modem and sure enough, that one works fine. No issues.  I have had no issues with the SBG8300 in almost a year and a half until today. What could be the problem here??

Guest wifi faster than default network on SBG8300

I just activated an SBG8300 and accepted the defaults. On the default network, I’m getting 60Mbps download. On the guest network, I’m getting 300 Mbps. What’s the difference between the two, and is there any harm in using the guest network?
