G34 | G36

How do I totally remove the 2nd home Wi-Fi and guest Wi-Fi from G34. Disabled all of these but Wi-Fi signal still transmitting.

I have a brand new G34 modem/wifi router that’s not even a week old. Worked great for first two days. Now everyday I loose internet connection but I still have a blue light on my modem. I unplug It for a few minutes and then it’ll work again.

We have an Arris G36 with a router mesh system and our Nvidia shield plugged into it. Both the wifi to the router and the ethernet connection drops 5-10 times a day. I have rebooted it, unplugged it for 5 minutes, reset it. disconnected everything and reconnected. Nothing seems to fix it.

My G34 router is 2 years old and has worked flawlessly for most of that time. However over the past two months my internet connection has gone down about 4 times for no apparent reason. Unplugging and restarting the router fixes the issue but I am concerned this will keep happening and possibly increase. Do routers wear out?

So, I have a Arris G34 that is approximately a year old and its not broadcasting ssid and ethernet ports not working. Everything was working great till I moved to a new house. I have Cox internet and I am receiving good signal. I can plug cox panoramic in and the internet works just fine. When I reboot or factory reset the G34 the ethernet ports light up while it reboots but then turn off and do not come back on no matter what I have plugged In to them. I cant seem to figure out how to login to the modems web page to check out the setting due to lack of internet.... Any advice/help before I try and do a warrenty claim will be greatly appreciated!

I purchased the G34 in March 2025. ISP is Cox w/ 500 mbps download speed and 50 mbps upload speed. Up until recently, I neared the maximum speed in both directions using an ethernet connection and slightly slower as expected using Wi-Fi. Over the last few weeks, however, the ethernet upload speed is less than 1 mbps, while the download speed is near 500 mbps. (The Wi-Fi speeds are unchanged.) But when I activate my VPN, the upload speed is ~50 mbps. I have reset the G34, but the upload speeds remain painfully slow unless thee VPN is activated. Any thoughts on how to increase the upload speeds when not using the VPN?

I have gigabit internet but my ethernet download speed is slow. I have bypassed the splitter and have my Xfinity coax cable connected directly to my Arris G34 Gateway router. When I check over my wireless connection I get 350 Mbps. When I check over my ethernet I get about 200 Mbps.

I have struggled with a DDNS provider, changeip.com, because the DDNS from my Arris G34 are not working to update with the correct IP address. They insist I must contact Arris, as they have stopped working on the issue. The token is right, the U and P fields are right (apparently, password is obscured) yet changeip support insists the request is malformed. Can you help?

i contacted comcast.net over five times but still dropped and intermittent wifi and slow nowhere close to 800mps which i pay extra

I upgraded my modem from a sbg8300 and my new modem G34 is slower when it’s supposed to be faster what going on I feel like I spent 200 bucks for nothing do I need to turn something on from the surfboard app to make the WiFi speed faster?? I would like some help if not I’m going return it and go back to my old modem they told me I needed to upgrade since my modem outdated but why my old modem faster then the new one doesn’t make sense I’m lagging like crazy with this G34

I just purchased an Arris Surfboard Wi-Fi cable modem model G36. I contacted Spectrum - my IP - they’ve sent the activation signal and see the modem on their side. They’ve sent reboot signals and it’s rebooted. They sent another signal, had me unplug for a full minute and plug it back in. The device maintains a blue light, my devices can connect via WiFi and Ethernet according to the surfboard app, yet there is absolutely no internet connectivity. What am I missing?

My arris g34 has a blinking green light on both Ethernet cables (I was not the one who set it up, one goes to the tv I think) and I can’t tell if it’s quick or not (a previous website told me fast blinking is not good, but didn’t say what the quick blink looked like), also I’m not even sure if it’s green or yellow, they’re very similar looking. I’ve tried plugging each cord into different ports, but with the same results (except for with the 2.5 g port, an orange slow blink). Help? also: most devices say “connected, no Wi-Fi” (I think that right)

Does the Surfboard G34 allow laptop computers attached via WiFi to utilize the Atmos Agent (i.e. VPN) to create secure connections with host applications? While other laptop computers also attached via WiFi not running the Atmos agent? Thank you

I am required to use a VPN for work. Have been doing so for many years. I replaced an older modem and router 4 months ago. The G34 was working fine until one day it wasn’t. My VPN connection drops after 10 seconds. My IT dept went so far as to replace my computer but the new computer has the same issue. I have rebooted the modem many many times. I saw reference to an article, but the link tells me to “check back at a later time” (!!!) If this article will help me, can it be emailed to me perhaps? http://arris.force.com/consumers/articles/General_FAQs/G34-G36-VPN-Passthrough-Setup or is there anything else I can do? I need to be able to do my job.

I replaced my 2019 Arris C-129 with the new Arris G34. I get internet service in my house but no longer receive connectivity in my cabana which is where I work from home and need wi-fi. The old modem worked great for providing connectivity and wifi to my cabana, but Cox said my modem was too old. Any suggestions for getting connectivity before I need to work Monday morning? I appreciate your time and advice. Thank you!

I just bought my 2nd G34, and Surfboard Central will not let me log into this new one, and when I try to register it for warranty on your site it says the serial # does not exist? So I can’t even start a chat with support since it does not recognize the serial #??? And no tech support by phone on the weekend?

I purchased the G34 Modem last week to replace an old modem that I had leased from my ISP - upon receipt, I followed all instructions, called the ISP to set up the new and she never could get it to “ping” on her end. It kept flashing blue. The next morning, it was solid blue, so I called back - she was able to identify the modem and got me set up, but could tell on her end that that the service was degraded, so she she up a tech service call. The tech was out this morning, tested everything and it is not the lines - we have good service coming to the house, but the modem will not connect. I have power cycled it and even hard reset it several times - but nothing. It will flash green, go solid blue for a moment, then back to flashing blue.

Hello, 1. I have a new G36. I have tried several times to use the Surfboard app but I keep stalling on the Register Your Device step, says WiFi Communication Error (000-1612) 2. I tried connecting directly to the G36 using the IP, it wants a password. Says the password is available in the app… see number 1 3. Customer support is closed 4. Tried the customer support chat since that is open. Can’t get past the warranty check after inputting my model G36 and the serial number Hopefully someone sees this soon Chat closes in an hour

I bought an Arris G 34 and I can't stream movies

My modem says connected but no internet. The blue light is flashing. Is this a modem issue, or ISP issue?

I want to access my wifi settings but do not know the password for the G34 modem. I did a reset with a paperclip already but need I still need a password. The sticker on the bottom has no password mentioned. Do I need a hacker or new modem?

I’m having the same issue on my G 34.

Breezeline (Atlantic Broadband) are unable to activate the G34 I just got using either the HFC Mac or the WAN Mac numbers listed. They need an actual CM Mac address. Where can I find this?

I just installed a refurbished G 34 modem router combination. How do I set up a password to access the Internet on my wireless devices?
