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. 

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??

The Arris router is not getting internet from xfinity. Try to use the app and is not working. 

Modem is activated, I get internet with ethernet but no wifi sbg8300

Online light green no WiFi light why

I bought a simple range extender. Can I use it without switching to bridge mode? Why can’t I find it in my network? Thanks for any help you can offer.

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?

I created a surfboard manager account with a different email, is it the same as this account?

I have the SBG8300 and I’m trying to activate modem but I don’t have a Ethernet port on my laptop. 

I have 2 houses. I bought a SBG8300 for one of the homes in January of 2024. It works great so I bought a second SBG8300 for my other home March 1st. It works fine but I want to change the password and am having trouble figuring out how to do it. I have surfboard manager from the first modem but cant log in.

I currently have the SBG8300 and I have Optimum ISP. I have had optimum for years now, but I recently moved across the state. I didnt have any problems before I moved, the internet went out maybe 5 times in 2 years, but ever since I moved it happens multiple times a day.  It happens randomly, and It is only out for a couple seconds or minutes max. It is wifi and ethernet. I have 450mbps down and 40 up, and I have 2 pcs on the internet gaming. Both pcs disconnect at the same time and come up at the same time so I know its not PC related. Things I have tried:  - new ethernet cable - resetting internet (button on back of router) - factory resetting internet (both holding button on router and through network webpage) - unplugging router from wall and waiting I am putting in a ticket with Optimum tomorrow to see if they know what is going on. I have searched the web for countless hours and have found no fix. Everytime I t

So I can get some of my devices connected (online) because some of my devices all of a sudden switched to the 5G network from the 2.4. Like the phone got on the 5G and maybe a couple of othet things and then some I had to put the password I. For them to get online on the 5G. But I still have devices like a Yale door lock/bridge  and 2 outside security cameras that aren’t working. I found out it’s because they will not use the 5G. I tried to go back in like I was encouraged to do and get my phone temp onto the 2.4 just to be able to connect those and then  they’d work on that and my phone could go back on 5G. . So  since zoning my own Arrus Modem which is a SBG8300, my internet company was not able to do much for me. They said I needed to contact Arris and tell them that I needed to have the 2.4 and the 5 two separate things, and I which accidentally clicked out of that chat and forgot the exact tech terminology. Something about they would need the gateway and the password. That what

Restarting modem, pc does not work, the problem is getting progressively worse, and app does not change settings.

I have tried unsuccessfully to connect my HP 8720 printer to my Arris 8300 modem/router. I’ve tried the usual turn off/on router, printer in the various sequences. I can see all of the router connections, but not the main one, which I renamed and re-passworded.  Thanks in advance for your help. 

Hi! I’m having issues connecting to the internet with my SBG8300. After losing power the online LED turns on but the WiFi LED will not turn on. I’ve power cycled multiple times. Tried plugging into a power strip and directly to the wall. I’ve tried to factory reset but cannot connect via the web interface. I tried to console into the Ethernet port and still the web interface would not work. I have called my provider and they also cannot communicate with my SBG8300. Any other suggestions? 

Mr. Moderator, before you tell me the SBG8300 firmware update is pushed out by the ISP, please be aware I have read the other posts on this issue, I have just got off the phone with Xfinity, and they say it has to come from Arris.  Regardless of who it comes from, please, just inform me and your every loving public what the latest firmware version number might be.  I have 01.02.078.04.NCS.  I saw that in an earlier post, but nobody answered the question.  Maybe it is time for the consumers to know the magic number.  I’m not asking to download it myself, just want to know if I need to push Xfinity for a newer version.I have issues with parental controls giving me “Operation Failed” errors when I try to add, edit, or delete items.  I’m not tech savvy and not sure firmware is the issue. I tried to reset the SBG8300, but it did helped. Parental controls work on some of my devices, but never seem to work on my son’s school issued Chromebook. One other question, as long as I

I just bought a SBG8300 to replace my old cable model and netgear nighthawk ac1900.  performance of the new arris modem/router is very disappointing.   I get 450mbps right next to the router,  60-80mbps 20-25 feet away,  and 0-20 mbps 30 feet away.   that’s far worse that the nighthawk that’s nearly 10 years old.  is there anything I can do to improve wifi signal strength or it’s just the way the SBG8300 is?

I have owned this SBG8300 for a couple of years now and ever since the day I set it up, I have not been able to actually see the ports forwarding details for any ports that have been previously setup. The screenshot bellow shows exactly what I am ever shown when accessing this page. I am able to add ports to be forwarded but I have no idea how to ever disable or edit them once they’ve been added since the information isn’t displayed regarding the current forwarded ports, even though they do exist.. It’s also important to mention that I have even tried using both of the Android apps that are on the marketplace and provided by Arris and I was unable to see the currently set ports being forwarded on there either.  Software:Software Image Name:AR01.01.139_050119_701.NCS.10Firmware Version:01.01.139.NCSRDK-B-LLC:rdkb-2.1-20161219SDK:7.0

Is TP Link compatible with SBG8300?TP Link AC 1750 wireless.purchased to get rid of Xfinity rental modem.I have 4 computers, 3 TVs, tablets and phones. All devices are operating unconnected to modem/ wi fii need to know if they are compatible and is this device going to operate all my computers and devices with adequate speed.  If so, I need step by step instructions to install.

I have the SBG8300-89A5-5G modem. I set up a new password and it connects (usually) with all my devices. However, it will not connect to my blink camera. When I try, blink says the password isn’t correct (it is I have checked it numerous times and it matches what I have it set as). This hasn’t been a problem with my old modems. I have tried to reset the modem and the blink camera. It will still not connect. Very frustrating!!  Help!

Activated this thru my internet provider, he says he sees it connected and all looks good to him, but neither a wired connection or wireless works. Can access webpage when wired with a designated ip. Cant access using auto ip. No wireless devices will connect. Wired device using designated ip will only get you to device webpage, no place else. The wireless networks are broadcasting, and accept password but dont connect.

I have to disable and enable the IPv4 DHCP server to get it to hand out addresses at least once per week.  It’s been doing this since I bought it and installed it a month ago.  I disabled the IPv6 DHCP server, but that has not helped.  I tried to find how I upgrade the router, but I haven’t had any luck finding that.  Here’s the version on it now:Software Image Name:AR01.02.078.04_092820_711.NCS.10Firmware Version:01.02.078.04.NCS

Hi All,I have a network created by a Arris SBG8300 modem/router. I am trying to access a remote Synology NAS running Plex on a DIFFERENT network. The SBG8300 firewall is blocking access to the remote NAS. I know this because.When I disable the firewall, all devices on the SBG8300 network can access the remote NAS and Plex server. When I access the remote NAS and Plex server from any other network, I can connect. The problem is definitely the SBG8300 firewall. So how configure the firewall to allow traffic through to the remote NAS and remote Plex? Thanks!

Some how my login password, which is password, expands to numerous ********** and will not allow me to change back to password. Tried clearing cache  etc but no lunch.  Need some help so I don't have to keep putting in default passwords for wifi access. Thanks,
