Can I connect a range extender to an SBG8300 modem/router by enabling bridge mode?

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.

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?

SBG8300 Internet cuts out randomly for seconds or minutes

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 think its fixed it toys with me and works for a few hours or all day wi

All the devices connected automatically from 2.4g to 5g - SBG8300

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 I

SBG8300 No internet and unable to access GUI

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?

SBG8300 firmware version

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 have your eyebal

Extremely slow Wi-Fi- SBG8300

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?

Can't View Information on Port Forwarding Page

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:7.0Wi-Fi Driver:4.6.92.8.26.0Hardware:Model:SBG8300Vendor:ARRIS Group, Inc.Hardware Revision:6 ----------I would greatly appreciate any suggestions or solutions

won't connect to blink camera- SBG8300

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.

DHCP Server stops working until disabled and re-enabled SBG8300

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

SBG8300 firewall blocks access to external NAS

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!

Green Screen or Buffering on Streaming Services - SBG8300

First of all, my speed test only shows 60 for download. That may be the problem? But I have an SBG8300, and I'm only getting sound on all my streaming services. The picture is black and buffering on Netflix. On Hulu and Peacock, I get sound, but the screen is green. Anybody ever have this problem or know how to fix it? I already restarted the modem. This problem is in my new TV. Old TV doesn't have this issue. On the TV with the problem, the home screens on all streaming services are good and clear.

SBG8300 intermittent internet connection

I purchased a new SBG8300 from Amazon a little over a month ago and it had been working fine. Last week the wifi connection started dropping out. Devices wouldn’t stay connected. It turned out that one of the issues was with my service provider. Their issue was all fixed on Friday and they even let me use one of their routers over the weekend to ensure everything stayed connected correctly. Now I have switched back to the SBG8300 and added the same ssids as before. Hardwired devices work as they should. 5G WiFi devices stays connected 90% of the time. 2.4G WiFi devices will not connect at all. The 2.4G ssid continually goes in and out back to back and never lets anything connect and even when it does, it doesn’t have internet access. I also had an issue with devices auto connecting even though the ssid/password are exactly the same as before. This is a continuing issue after multiple power cycles and factory resets. What could be the issue?

Password change attempt on SBG8300

The http://192.168.0.1 will not connect. It’s as if it does not exist. I finally was able to go to another webpage while looking for entry, (SBG8200), finding an SBG8300 access page beneath & accessed the numbers above, with https:// Redirect. I clicked the box “Proceed”, the page says “502 Bad Gateway. Certificate verify failed: self signed certificate in certificate chain”. Why doesn’t your own (ARRIS) web pages work??? Remind me again why I spent my money to not have access to my Surfboard???
