intermittent disconnects SBG8300

Hi All, New to the community here.   I’m having a problem with getting periodic disconnects with my SBG8300 while playing the game Fallout 76 (Bethesda Softworks).  I have been back and forth with Bethesda Tech Support about this problem and we have gone through many different troubleshooting scenarios. For clarity, the disconnects occur anywhere from 15 minutes to half hour and up to an hour of game play. What happens is the game notifies me that I have been disconnected and returns me to the game’s launcher.   Working with tech support we did find recently that by enabling bridge mode in the modem, which bypasses the router portion of the modem seemed to have a positive effect and I had no disconnects.  Bridge mode disables wifi and only allows ethernet connect.  Which leads me to my question.  Is there something I can check or do or set in the modem to further troubleshoot my problem.Any help would be greatly appreciated.

SBG8300 Online but nothing else

Lighting cam through my area. Power went out for a few hours. My SBG8300 modem/router shows online blue solid light but nothing for WiFi. I have tried to hard reset but the modem doesn’t respond after holding for more than a minute. Unplugging and plugging back does nothing.

SBG8300 internal and external port fields not shown

I have multiple computers that all need the same internal port number exposed on separate external ports (example : router:1001 → hostA: 443, router:1002 → hostB:443)When I try to set port forwarding settings per the documentation (https://arris.my.salesforce-sites.com/consumers/articles/General_FAQs/SBG8300-Port-Forwarding-Setup/?l=en_US&fs=RelatedArticle)  Using “other” as a “common service” I am never presented with the internal and external start/end port number fields, just Start and End Port.  Because of this I cannot set separate internal and external port numbers.Am I doing something wrong or is there a configuration / host issue that I need to address to make this work?Thanks!

SBG8300 Port Forwarding FQDN on LAN

Port forwarding works from Internet to my server, eg: https://SnellsNotebook.us properly produces a web page to an internet user.  However attempting to connect to the server using its FQDN (SnellsNotebook.us)  from device connected to the LAN (wired or wireless makes no difference) results in accessing the router’s login web page.  This behavior is unique in my experience, as all of the routers I have had previously would resolve the FQDN the same regardless of whether the request came from WAN or LAN.Static address for my web server srv1.local is 192.168.0.10I have forwarded ports 80 and 443 to 192.168.0.10Port Triggering is off.  RIP is off.  DMZ is off. Symptom remains if 192.168.0.10 is in the DMZ. ALG has all options checked.  No devices are bridged.I have seen references that claim routing to the FQDN from with the LAN are not supposed to work.  If that is the case for the ARRIS SBG8300 can anyone recommend a cable modem/router that will perform the way I want it to?

cannot route LAN -> WAN -> LAN via port forwarding

I have a web server being port forwarded (ex: www.mywebsite.com).DNS resolves properly from every client, inside and outside LAN.If I try to connect via a browser (Chrome or FireFox, Windows/Linux/Android) from INSIDE my LAN, it will FAIL.If I try to connect via a browser from OUTSIDE my LAN (ex: same cell phone but not on Wifi) it will WORK. Am I missing a configuration setting somewhere, or is this a bug?

2.4 Network Not Broadcasting Changed SSID and Password

New 8300 User. When I logged in on my iPhone using the default settings for the 2.4 network I had internet. I changed the SSID name/password of that 2.4 band but the gateway is not broadcasting it; it still shows the default. I’ve restarted the app and rebooted the gateway. I’ve also tried logging into the Web interface but I can’t seem to get in. Advice please. i have a ton of 2.4 band devices that are wondering why I have deserted them...

change main network in Surfboard center app

I have a new SBG8300. I have gone through all of the setups. I changed the name of the 2.4 GHz SSID to a user friendly name. I was able to connect. Then I went in to change the 5.0 GHz SSID and I tapped on the option 'Enable Single SSID for 2.4G/5.0G bands'. It did not change the 5.0G and now the 2.4G that I successfully changed is no longer available in my wifi network list. How can I get the 2.4G to show and set it as my Main WI-FI network?

SBG8300 shows Online and WiFi lights on after Co-axial cable disconnected

Hi,I have an SBG8300.My internet was down this morning, but the online and Wi-Fi lights were illuminated. I tried in connecting and reconnecting the power. No luck. Then I tried resetting with a paper clip. I held the button down for a minute (timed). Nothing happened. The lights stayed on the whole time. When I disconnect the internet cable (the power cable is the only thing left plugged in), the online and wifi lights are still illuminated. Even if I power cycle, the second I plug the power cable in, it says I have wifi, even without the wifi cable.I’m at a loss for what to do here. Is there another way to reset my device? Do I just need to buy a new one?

Surfboard Central App not showing the correct device / Unable to proceed with login

I just downloaded the app, to try and run a speedtest, but my app is showing the wrong device connected.I have a SBG8300, black modem/router. I set this up via the web portal, but when I logged into the app, it is showing it as an S33 white modem only.This is preventing me from doing a wifi speedtest.Anyone else having this issue, or know why it's happening?

SBG8300 Static IP Addresses LAN devices

While this modem seems to work, it does not work well at all! Contacting a human to discuss isn’t available it doesn’t seem without paying for it during the warranty period.  (ITS still under warranty!)Several issues I have.   The one that is driving me absolutely crazy is after I set the STATIC IP’s for devices on my network that MUST stay at a static location (CAMERAS).  I set up all of my static IP’s and turn on the network for them all to get their proper IP’s.  That seems to work well.  After a couple months, ALL of my static leases are GONE!  Cameras are at other IP’s.  Set to static again and again month or so later… GONE!  Other issues that I have had and I just STOPPED attempting to use it… I want my LOCAL IP’s to be 10.199.30.XXX.  I setup the DHCP server side for that with starting IP’s at the 20’s to 250.  Works GREAT… UNTIL… A month or so, the SUBNET changes to something that is WAY out of scope and NOTHING works.   I have to factory reset and start from scratch.  So I sto

Arris Surfboard SBG8300 2Ghz connection issue

Every time I need to connect a home device to the 2G connection it is a frustrating experience.  Most of the time I have to keep trying over a period of days and then finally it connects  -- and thankfully -- stays connected and reconnects following power outages just fine.  BUT I can’t go on like this having to repeat this process when a device needs to be reset.Here’s what I have discovered with my Orbit Sprinkler Control WIFI Hub:Connecting to 2G band, on entering Surfboard WIFI information, app just spins forever.  Never connects.Enable Hotspot on my phone, on entering WIFI information, app connects immediately. Enable guest network on Surfboard, on entering WIFI information, app just spins forever.Enable guest network on Surfboard, on entering WIFI information with on-purpose bad password, connection refused in a couple seconds.Enable guest network on Surfboard, disable authentication completely, on entering WIFI information app connects immediately.So … what’s the problem with th

surfboard SBG8300 - Lag Spikes

I got this modem router ~60 days ago (of course past my return time) and have recently ran into what seems like bottlenecking/spikes in ping randomly while gaming/streaming.  I originally thought this issue was just my pc but then my devices connected via Wi-Fi also had buffering hiccups This didn’t start until yesterday. Unplugged and replugged everything. Contacted ISP, everything was good on their end. Deleted temp files..etc…etc. only not new part of the hardware is my 30ft cable wire. However, it was working fine with my previous modem router and internet speed. when I test the speed I’m at expected levels. But again, it’s random when it happens and it’s across multiple devices. has anyone ran into this? Any help is welcome

Provisioned SBG8300 active, but "no" internet

Alright, here’s the deal:  I had recent cabline line with 90VAC on the line - yep, shocked at one point, so I checked.  My original modem was squealing, assumed it was dead.  Neighbors had internet.  Modem was an older Cisco DPC3010, so nearly a decade old, but still fast enough for me.  Assuming the dead original modem, not aware of the voltage on the line, I went and bought another modem so I could finish my work projects that were past due.  Plug new modem in instantly squeals at me and all lights solid - no change since then.  This was not the SBG8300 model.  So now two dead modems.  I’m an electrical engineer doing power system and control system designs. At one point earlier in career I was going for my Cisco CCNA; I decided to change careers and didn’t need to continue certification, but am not a complete novice when it comes to IT type stuff.Several calls with xfinity, and they have tech come out and see voltage, works on line, and requests new line be buried and to have other
