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.

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.

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?

xbox keeps displaying upnp unsuccessful error on G34

Every other device other than the Xbox has connected and works perfectly. I’ve tried everything I’ve seen on different theads to fix this problem. Factory reset, port forwarding, various setting and security protocol changes and nothing has worked. Xbox connects to modem/router g34 but can will launch any games or apps like Netflix, Hulu, max, etc. save your time and mine and don’t recommend I do anything I already have as I’ve done them multiple times with no success

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

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.

SGB8300 "Connected" but no wifi or internet

We had winter weather in GA and woke up to the wifi being out. No outages from Xfinity. Restarted the router, connection shows as blue, but no wifi. Xfinity can't detect it. Ethernet connected computer can't see it. Tried doing a factory reset, but nothing happens. It seems to be basically unresponsive. Any ideas?

surfboard login web will not accept password and unable to set up the SBC app on G36

The app wouldn't connect to my G36, kept getting 0000-1614 error code.  So I logged into the web interface.  After updating my password, it asked me to log in again.  Fine no problems, BUT it won't accept my password!  Now I have no way to log into my router/modem.  It keeps telling me to use the email address I used for the app.  Did but it still will not acknowledge my password.  I've reset the modem so many times is sad.  I'm fed up!  How do I get my password to work on the website since the app won't work?

App prompts to factory reset G36

I have set up my G36 via the web browser.  When I try to log in to the router from the Mobile app (on the same network) it prompts to do a factory reset on the router.  I have tried the app on two different mobile devices on the network and they both prompt for factory reset.  I have no problem accessing the router via a web browser.
