A browser message on Chrome, Edge, Firefox, Opera, and Linux browsers may appear when accessing Web Manager on SURFboard gateway models SBG6400/SBG6580-2/SBG6700-AC/SBG6782-AC/SBG6900-AC.  The message includes 192.168.0.1 uses an unsupported protocol and ERR_SSL_VERSION_OR_CIPHER_MISMATCH.  The Web Manager uses an earlier version of the TLS (Transport Layer Security protocol) protocol and does not match the version allowed by the web browser.   Safari browser on Apple PC and mobile devices are not impacted. The workaround to access the Web Manager with PC is to use Firefox browser and set the TLS to version 1.   We recommend to revert the TLS setting back to default after completing the Web Manager task. Set TLS version 1 in FirefoxEnter about:config in the Firefox address bar and press the Enter key. Click the Accept Risk and Continue button. Enter security.tls.version in the Search preference name field, .  Locate security.tls.version.min and click the pencil icon.  Enter the value

BEST WAY TO UTILIZE CAT 5 BETWEEN FLOORS

I have a G36 on one floor and have a CAT 5 that runs from that location to the second floor.  I am trying to figure out how to have one SSID network that covers house and right now the G36 isnt doing it.  I envisioned if I could have a wifi router hardwired to the G36 and then have another something on the second floor that is connected by the CAT 5 in the wall to either the G36 or the first floor wifi router?  Any help would be appreciated what i should buy or do.

accessing the management interface

Hello I tried accessing the management interface by entering 192.168.1.1 in my browser, but the system prompted me to enter a serial number. I entered the serial number on the device, but it kept saying it was incorrect. Yes, I tried using the default username and password, but the system still asked for the serial number. I used a paperclip to hold the reset button on the device for about 10 seconds until it restarted. Then, I tried logging in with the default username and password. The issue still persists after the reset. Please help me resolve this problem.

Reset wifi settings model SGB6580-2

I would like to change my wifi name and password. I no longer have the software that came with the router. I have attempted to change my settings by entering my IP address and Router IP into a search engine, but I am unable to login in with my username and password. How can I change my wifi name and password? I am also unable to login to the surfboard app to change settings that way.

How to get refund for returned product

I returned/refused delivery on a modem on February 5, 2025 and confirmed receipt of product by Arris on February 19, 2025. I was told to expect a refund within 2 weeks of 2/19/25. I called on 3/5/25 to check on refund status and was told it was expedited and I should receive email confirmation. No message received. I called on 3/6/25 and was again assured it was expedited and I should receive a phone call. Still waiting for a phone call. In spite of confirming my email address multiple times, I have never received an email, not even confirmation of my original purchase on 1/31/25.

SBG7580-AC WPA2 and KRACK

I have an SBG7580-AC wifi gateway running firmware {edit : personal information} (Xfinity is my ISP since a few months ago.) Does this firmware version correct the WPA2 security vunerabilities exploited by KRACK or do I need to acquire another wifi gateway model that supports WPA3?

192.168.0.1 DOES NOT GO TO ADMIN PAGE ON ANY BROWSER onSBG6900-AC

Post after post after post says you cannot put 192.168.0.1 and get to the admin login page any more.  There used to be a Firefox work around and everyone keeps posting that as the solution.IT DOES NOT WORK.  No matter what browser I used including Safari IT WILL NOT WORK.Does ANYONE know how to login the modem as of today 12/29/2024?My modem is a SBG6900-AC but that doesn’t matter because based on the comments many different Arris modems are having the same problem.Unplugging it doesn’t work, factory resetting it doesn’t work.  NOTHING WORKS.And why isn’t Arris doing something about it.  Apparently no browser due to security reasons will let us log in to our modems because we have an old protocol or something.

What is the latest firmware update for SBG6782-ac?

I understand my ISP should update my firmware on my Sbg6782-ac.   I am curious as to how current my firmware is.My firmware currently is SBG6x82-8.6.0.0-GA-08-046-NOSH.  If current, just how old is it? 6 months or years ago?I dont seem to be getting the speeds I should be getting and get a lot of stops and starts.   I know I have had this modem for a long time…maybe I wore it out…

Motorola Branded SBG6580 wireless settings locked out

One day, my router stopped showing up on the networks list, but the phone line it's tied to on the ethernet still works. I quickly verified the antenna wasn't working, so we used these  range extenders for a bit. They randomly dropped the connection all the time, so today I tried turning it on in settings, but when I go to any menu in the wireless section, my browser gives an ERR_CONNECTION_RESET. Is this some over-the-air mass brickery? Unlikely. Does anyone have any solutions?

Is DOCSIS 3.1 Allergic to Wifi & Voice Combo?

Is the lack of a DOCSIS 3.1 Modem-Router combo product with Wifi & Voice 1) an Arris marketing decision, i.e., too small of a market, 2) an Xfinity compatibility issue, or 3) an engineering task to great to integrate the features within 3.1?

make an app that is useful since connected device are not listing.

What about you make an app that’s useful? The current app doesn’t show connected devices. One has to connect to the web GUI to see the connected devices. Please hire someone competent to resolve the issue.  Best regards, Frustrated and disappointed Customer
