Surfboard SBG8300 and Xfinity connectivity issues

Hello.  I am using an SBG8300 to connect to Xfinity.  Most of the time it works just fine, but several times lately the download speed has dropped from 45-50 Mbps to under 5Mbps.  If I unplug the modem, wait a couple of minutes, and plug it back in, everything returns to normal.The Xfinity service doesn’t appear to be the issue.Any idea what this could be.  I purchased the modem less and a year ago, so it’s still under warranty.The last time I’m aware of it happening was last Wednesday and Thursday, but I was away over the weekend.  It hasn’t happened today, as far as I can tell.I’ve downloaded the logs from the model administrator panel.How do I proceed from here getting technical/warranty support?Thanks.

SB8300 Connection Drops Every Hour

As the title says, every hour at nearly the exact same time my connection drops for ~1-3 minutes. Has been happening for roughly a month. Drops both wifi and ethernet connections. Only device connected is the PC.I had a cox technician tell me to my face it was from ‘overheating’ on a router that had worked just fine in warmer conditions, nevertheless the signal drops like clockwork and not spontaneous heat problems.Have also set all ‘lease duration’ settings to forever.This set of logs is from today, where the two at 11:53 correspond to (I think) when my PC was first on (the only device connected) on, and today all disconnections have happened at xx:53.Any help is appreciated, but I’d like to make good on my active warranty as this device is <1 year old and getting a new device would silence at lot of likely bogus suggestions I’ve received so far.

Intermittent internet connection on SBG8300

Why do I have to reset my modem sometimes multiple times a day? Other times. Once a week. Sometimes every day. .y dad has the exact same modem and never has to reset. It's just the wifi. Both 5 and 2.4. Hardwire works no matter what.

How do I use an SBG8300 as a router only?

Hello. I have spectrum internet rated at 300 Mbps upload and download, “symmetrical speeds” as they would say. The SBG8300 is on their list of compatible consumer-owned equipment. My equipment includes a SBG8300 that I own, and a modem (not currently plugged in) supplied by Spectrum. When just using the Spectrum modem, hard-wired to a gaming PC, speed tests show the provisioned download and upload speeds of ~300 Mbps.1. I currently have the SBG8300 setup connected to the DF cable, and an Ethernet cord connected between the SBG8300 and a gaming PC. Speed test shows 362 Mbps download and 11.01 Mbps upload, and was done from the hard-wired PC. WiFi connections to cellphones, Xbox, are a bit spotty, and I’m sometimes having issues with connectivity in online games on the PC.Spectrum techs have told me that the SBG8300 is not rated for “symmetrical speeds.” Is that true? It seems true… what could possibly be wrong here?2. To avoid utilizing Spectrum’s subscription based Router offering, and

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

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.
