Ethernet (wired connection) on SBG7600AC2 not working.

I just noticed that my Ethernet connection does not work from my modem. The wifi that I use daily is working just fine, but I recently noticed that my only wired connection is no longer working. My only Ethernet connection is my security camera system, and I have not checked to see if it was online in months, so who knows how long this issue has been going on for. I have tried to connect the Ethernet cable to different devices and use different Ethernet cables and reset the modem to no success. I am wondering if there is an easy way to tell if the Ethernet ports are broken or if there is some way to reset them. Both the green and orange lights are always on for all 4 ports even when nothing is connected. Is this normal? Or does this in itself indicate a problem? There was a power surge in my neighborhood a year ago. Could this have damaged the Ethernet ports but not the wireless Cabo ability of my modem? Any information would be appreciated. My modem is no longer under warranty.

Fix parental controls on router G36 - hacked?

Long story short the Surfboard app parental control is working. However, I ran out of “blocks” (seriously, only 32 !?), and saw that the gui web interface also allows for blocking from there also. (1) The gui parental controls do not allow for dashes “-”. Given there are many domains with dashes, why not? (2) Everything was going fine. I had 25 listed in gui. No problemo. After we had to power-reset one day I saw they were down to 15. I added them again. A few days later we had to power reset (not a factory reboot just a power outage) and once again down to 15. I added them back once more. Then I saw that the ones I added back, although they were listed in the gui software, they were not actually blocking anything anyway (I tested from a laptop afterwards). I come back and they are still there and listed. They stay there and remain listed. Until we have a power cut. Then they vanish as if by magic. I have had a problem with hackers. I think they have done something to the router to sto

SBG8300 limiting speed to 60mbps after router mode

Today I switched my SBG8300 from the modem & router mode to WAN over ethernet mode - since I switched to fiber internet. Unfortunately, the SBG8300 appears to be limiting my 1000mbps to 60mbps, both for ethernet and wifi. I tested running a cat6 cable directly to the fiber modem and I get the full 1000, but when I run it through the SBG8300 I only get 60. I’ve restarted it several times and ensured all ethernet ports are set to 1000mbps. Any solutions or settings I’m missing?

Gateway Issues (G54) slow speed internet connection

A few days ago, my Internet on my G54 gateway started acting slow. It takes a while to load an entertainment app like YouTube, Netflix, Hulu and getting high ping while playing games to where it’s unbearable. But when doing a speed test on my G54 it says I’m getting over 300 download speed and 39 upload. So why is my Internet being so slow and having a high ping in games? Is it my modem thats acting up, or my ISP?

new to G36 - SBC app logon not working

The modem is working but I’d like to get the app up and working so I can simplify the password. The QR code that came with the unit doesn’t work and I don’t seem to be able to do it manually. I’ve set up a password and user name, but that’s about it.

Latest Firmware for the SBG7600AC2

I saw two questions on this topic and the response was that the latest firmware is pushed out to the internet service provider. But my situation is I chose not to use any router from the service provider and purchased this on my own. So I would have thought I should be able to update the firmware on my own as well (as and when there is a firmware update).

Error Code 0000-1612 at the regerter my device page on G54

As the title states, everytime I get to the "register my device" part of this app, I get the wifi communication failure message with error Code 0000-1612. I've reset my device numerous times with both hard and soft resets, un-installed the app, etc. Apparently I need to get through that page to make an account username and password to get access to my admin page on my g54. This is more than frustrating.

Xfinity blocking port 80

I have the Arris SBG7600AC2 as the cable modem and wireless router for Xfinity service. When I try to add the Arlo Netgear camera hub, it cannot get to it because port 80 is blocked. I set up port forwarding on the Arris but the port does not seem accessible. How can I troubleshoot this issue?

Updating the device access and password.

What are the steps to update my SBG8300 w/WiFi access and password. I need to improve my security beyond default. Thanks so much for any help. I prefer Arris over all other brands and have had great luck with it for years - quality technology and great value. Also, is there literature on the SBG8300 for resetting WiFi names and password? I want to make everything difficult for wannabe hacker - maybe hide 5G connections. Thank you

Speed is too low while PC is in 2nd floor

I recently setup the modem/router and I get excellent speed on all devices except one, which is a HP laptop (when it is far from router). The speed that I am getting in the laptop (Windows PC) is excellent when it is on the same floor. But when it is in the second floor, the speed is 20-30 mbps. Interesting thing is that, the speeds are pretty good when I check from an ipad and chrombook while in the second floor. It appears that the PC is having hard time to get the performance just when it is in the second floor. Any idea what could be causing the slowness in the PC while there are no issues in chrome book and ipad. Thanks . Nm

Unable to connect to internet on G34 modem.

I have been unable to connect to the G34 modem for 3 days. Sparklight verified that the modem has an internet signal going to it and the light is solid blue one the modem. We howevere cannot connect laptops, phones, or TVs to the internet. I tried to reset it and then the app was unable connect to it to set it up. There’s an IP reset address 192.168.0.1 but it WILL NOT work. The Surfboard app has logged me out and will not allow me to log in. Please help. I pay $50 a month for wifi and I want to actually be able to use it. Side note: the modem is only a year old. We bought it in January 2024.

Impossible to enable the DCS protocol in the 2.4 GHz band. My modem/router is the SBG7600AC2

I have been checking the tools of the 2.4GHz band to make it better and I found the dynamic channel selection that will be so helpful to me. However, to enable this one remains in gray; I have my router in auto for channels but in the advance part of this one is not letting me turn on the DCS. Also, I am steering the band with the 5 Ghz. I will appreciate your help :)

Network Connectivity problem with G36 Modem

I bought G36 modem in May 2024 and have been having no problem till about a month ago. Now I have to disconnect and connect the power several times daily. The streaming on my TV’s last only about 15-20 minutes after which there is no streaming and the screen states there a Network problem and to disconnect and reconnect the power source to the Modem. My internet provider is Xfinity. Some of the letters in the Surfboard community from 1 year ago,state that Arris is working on an update. Do they have an update? If so how can I get it. Is this a problem with Arris or Xfinity?
