SBG8300

Pretty simple:  Using the Surfboard app, showing internet speeds of 450 mbps but shows only 70 mbps on WiFi which is observed on connected devices.  I’m guessing it’s something very simple I’m missing.  Using spectrum.  At my home when I updated to new modem immediately WiFi went to 350 mbps. 

Hello, My SBG8300 is blinking both lights at the same time (fast blue on both) after a factory reset. My MediaCom technician checked everything and seems that my router is the issue.See the attached picture. Is there anything I can do, or is it the end of it?Thanks

I got the SBG8300 a few weeks ago and having some video lagging issues with my laptop. I’m paying for 400Mbps. The laptop has an Intel wireless-AC 9560 Channel Bandwidth of 160MHz on 5GHz. I did SpeedTest from about 30ft from the router. and get about 100Mbps. My iPhone gets 375Mbps from the same spot. I don’t know about the wireless on the iPhone but is this a fair comparison?Does the SBG8300 go to 160 or is 80MHz max?  Would it help if I had a 160MHz router?

I recently upgraded to the SBG8300 router. I have reconnected all my wifi devices for the exception of my Google Mini. It fails to connect via wifi. I have performed a hard reset to the mini, added both 2.4g and 5g as network options,, tried new google mini and spoken to tech support. It worked fine with my old router. I use it as the doorbell chime for my Nest front door camera. Google has no ideas and claims it’s the set up of my SBG8300. Arris tech support can’t find the answer either.

Hello.It seems that my modem is bricked. Everything was working until the connection dropped. One solid blue light appears for the power icon. Browser will not connect to 192.168.0.1 or alternatives. Tried 15s , 30-30-30 method to factory reset, doesn’t work. Power cycling multiple times does nothing as well.Can this be salvaged? Any help would be appreciated.

Xfinity keeps emailing me stating my Arris Surfboard SBG8300 is no longer compatible. We’re supposed to be getting 800 speeds and are getting 500. Someone told me this is because the SBG8300 is known for having a defective puma chipset. Is Arris offering a fix for this? Mine is still under warranty and I did purchase a 4 yr product replacement plan from Best Buy. 

When I try to connect a 2.4 ghz device (smart plug, etc) I either get an incorrect password when trying to connect or it gets connected and then drops.  I know the password is correct.

wifi speed coming from SBG8300 only 5 feet away getting 53mbps on 2.4ghz & 5ghz yet with ethernet hardwired to Orbi the wifi is 890mbps.  

Just bought SBG8300 Modem and Wi-fi in one. It has a Wi-fi cord that plugs from Arris modem to computer.  Now I can't carry my laptop anywhere because it is connected to modem. What can I do?

Do we need to update firmware?  My current firmware is 01.01.137.NCS?

Have a SBG 8300 gateway and I am unable to connect to my work server. Internet connection is fine. I unfortunately have basically no understanding of how this works. My IT person says it’s a xfinity problem, xfinity says it’s a modem problem. Which I believe because I can log on everywhere but home.  

Why does the Surfboard Central app keep saying no network available? But it show all Wi-Fi units online. And can't do a speed test .

Sbg8300 isn't recognizing the 2 play fi devices that worked fine with my previous router. I run the setup routine but they don't show up, have done factory resets on both devices.  Am thinking there may be something in the surfboard setting preventing the discovery of them.  Would appreciate any suggestions or insights. Thanks in advance.

Ethernet. Ports not working there blinking red. Can't connect firestick say connected but no internet. Same thing with Mac computer 

Hello my name is Brendan I’m a Charter Spectrum customer I recently rebooted my SBG8300 status light is indicating firmware download I looked in the app and web portal no prompts for action what should I do any ideas answersThanksBrendan

When I go to Arris Surfboard in the router (SBG8300 btw), I go to parental controls to manage devices, all I get is the option to manage devices (which is enabled) or access type (which is set to allow all) and even when switching these, I still get no option to add and manage a device. Its also keeps giving me bad certificates when using Chrome, Firefox, or Edge where it gives me a risk warning when going to 192.168.0.1 and each one tells me my browser is out of date and not compatible, I dont know if this is the issue causing features to not work or not, but firmware and browsers are all updated. any solution?

Hi there, trying to complete the surfboard app set up for SBG8300 and continuously getting an error. Are there any troubleshooting steps available for iOS devices, please?

Hi there,  My friend recently purchased SBG8300 and I was helping her in setting up the device. During the process there was a security check and that was asking for a captcha code to type in, but it was blank, and no captcha is available. this was on the surfboard central app.when I tried completing it in 192.168.0.1 on the network set up wizard step 1, again there was a blank captcha code and was not able to complete the set up. I will appreciate if anyone can help me with this. 

I recently setup my Modem (SBG8300) to bridge-mode, and now I cannot get to the modems admin page.I can get to the page sometimes. Itll load maybe 1 out of every 10 times, but I cannot get past the login page (192.168.0.1/login.php). I’ll get a page that says “this site can’t be reached”..Any ideas? 

I have a sbg8300 and the wife bought a new phone. Trying to connect to wifi and it doesn't accept the password. I deleted my connection on my tablet and tried to log in and cannot connect. Any help will be appreciated. Thanks

I have an SBG8300 modem/router connected to Cox cable.  Last year it was working completely fine.  Then I moved it to a new house - same Cox cable - but had to buy an aftermarket power cord from Amazon.Now the internet drops once a week and I have to reboot the modem (unplug and plug it back in) in order to get connectivity back up and running.Any ideas?  Is the unit overheating?  Is the aftermarket power cord causing issues?  The modem/router is roughly 1.5 years old and for several months, wasn’t even being used.Thanks!

5 months ago my brother-in-law purchased an Arris SBG8300 Modem/Router, which he understood would eliminate a monthly rental fee from Cox Cable.  He has issues communicating so I advocate for him.The Arris Modem/Router worked fine for about a month and then started to degrade as far as buffering. When we called Arris Customer Support, we were told the problem was how Cox Cable set up the Modem/Router.My brother-in-law then had a Cox technician come over.  After several tests, the technician concluded there was nothing wrong with the internet, that the buffering was in fact the Modem/Router.We then called Arris customer support back and was told to change some settings in the Modem/Router via the computer.  The changes made no difference in the what was now constant buffering. When we called again, a different Arris customer service person would suggest the same settings as before.My brother-in-law then took the Modem/Router back to Best Buy, but was told

how do I assign 2.4g to one device and 5g to another

Carrier thermostat won’t stay connected to the wifi. Is there a setting on a Surfboard 8300 that I need to change?

We just bought the SBG8300 modem. I changed the network name from the factory setting of SBGnnnnnn to a custom network name and pw which is easier to remember and type in. My Mac connected to it with no problem, but the two PCs in the house always rejected the password. We finally had to select the secondary (guest) network with the unchanged network name and password.   Why can’t the Windows computers connect to our custom-named network?
