G34 | G36

Why is my devices with lan cable the only devices lagging and when i go to the app it says that device has poor single can pls help.

My Arris G34 has been deemed defective by Xfinity. Their technician checked all of my cables inside and outside and they all have strong signal. The Surfboards light is green and flickering and there is no wifi available. My warranty runs out Feb 28th, 2024. I need to get this done quickly, as I also have no security system because of this and there's been a lot of break-ins and thefts in my neighborhood recently.

I have a new G36 with spectrum as service provider : I recently spoke to spectrum for the reason of slow speeds and continually intermittent connection. I have 1000 mbps and 6 month ago I had spectrum come to my house run a new line inside and out side . Can I get a solution for this I dint find any other way to contact you for service and spectrum blame the issue on my modem . Thank you

This morning my wireless connections were working but I had no ethernet hardwire connections. When I checked the router, none of the Front Panels lights were illuminated. I logged into my router and checked Gateway>Hardware>Front Panel and Lighting Mode was set at Normal. No firmware updates were reported to be installed. I contacted my ISP to check my connection which was at full speed. I proceeded with a Gateway Restart which re-established my ethernet Hardwire connection, then performed a Factory Reset and Unplugged the Router for 1 minute. None of these procedures restored the Front Panel Lights to illuminate. Is there a new Firmware Update that I can download and install? I currently don’t have the link to Arris Firmware Updates and need that link to see if this will solve my issue.

I just did a hard connection to my TV with an Ethernet cable and all I get is an amber blinking light

I randomly lose access to Xfinity for all MAC filtered devices on both frequencies. Working with Xfinity via their app and chat is truly frustrating. A power off/ reboot does not resolve the issue of the gateway connecting. I end up having to connect my PC to the G34 and set both 2.4 and 5.0 to “Allow All” and save both configurations which negates the use of the manufacturer’s MAC address, All devices will then connect to Xfinity internet. I then change both 2.4 and 5.0 to “Allow” and my devices are then able to connect once again to the internet. This lose of connection appears to be random as to when it will occur. The fix always appears to be going to “Allow All’ and then back to “Allow” for MAC filtering. Anyone have any ideas as to why this is occurring, and why making the change back and forth for filtering resolves the issue?

New G36 cable modem/router. I only have the primary and one guest network enabled. The others are disabled but the router is broadcasting 15 or so ‘wave_xx’ SSID. They shows as being unlocked but you cannot connect to them. I’ve thought there may be a bug where you have to enable the network, then disable SSID broadcast, then disable the network again. This didn’t help. I’d like them to not broadcast. Any ideas?

I have dealt with Arris Cust Svc 4x and have had Sparklight Techs out 3X to figure out why I cannot get more than about 250mbs download speeds through ethernet connection. I have a 600 mbs plan and should be getting very close to that via ethernet. Sparklight checked the incoming signal to the router and it came up 950mbs. Throughput from the router registered in the low 300s. Sparklight says it’s a router problem, Arris says the upload power is too low, currently at 41. Sparklight says they do not run the power any higher than that in their system and says that the power difference is not creating the low speed through put. Arris says it does. Sparklight will not change the power settings. Arris had me change the WiFi channels to lesser used channels saying that it could make a difference even with Ethernet speeds? What???? So I did a factory reset, changed channels and everything else exactly as they said, waited 24 hours, did a power cycle…..no joy….same issue. I’ve had this router

I need to change my wifi security to be able to connect my Canon MX922 printer to my G36 router, apparently. But when I go to the Arris login page (192 168.0 1) it says that my login credentials are invalid and that I need to use my email address from the app, which I am. It doesn’t give me any other options. I can see all of my network info on the screen at the login screen, I just can’t modify any of it without it accepting my login. I’m about to lose my mind. I’ve spent so many hours trying to do this over the last 2 weeks I just want to scream. Now I can’t even use my printer cable hard wired into my computer to print, I used to be able to before.

Over the last week several time for no reason G34 restarts. Amber blu and green led fronts flash etc.. All Ethernet in back go dark at start. Sometimes when it reboots I get usable internet for 2-3 minutes then reboots again and nothing. Unplugged it last night. My ISP is Astound in Chicago area.This morning plugged back in booted up and has been good for an hour. ALSO HOW CAN I FRLASH THE FIRMWARE UPDATE???? Don’t tell my m ISP will do this . I own this G34. Any Ideas??

I try to log in to my G34 router via the browser GUI settings and it says the certificate is not valid in any browser used, Chrome, Firefox. I was able to log in in December 2023, but have been unable to since. I have updated all browsers but to no avail.

I have over 50 wireless devices in my household from “smart light bulbs, Amazon Devices, TVs, Xboxs, Smart Phones, Smart Energy Meters, & Home Security”. How many wireless devices can this router truly support. I am fully aware of how many routable addresses are available by default, but this device seems to become inconsistent around 30 devices or so. Any help would be great… and I still hate the fact that I can’t access this device using the mobile application without having to go through the entire setup phase again. This may become a $200 paperweight very soon. Cheers :)

Hi Arris, I am trying to set up the android app and trying to connect to the modem. But the captcha always says incorrect captcha, though the correct characters were entered. I repeated this step atleast 30 times before giving up. Is this an app issue on andoird. Please don't insult your self any more by replying " enter correct captcha it should resolve the issue ". I can upload a video if needed to show your superior app in action.

I live in a place with many WiFi access points around me. In order to get good connectivity, I set my 5G radio control to manual and select a free channel. It works well and i get good throughput. The problem is that even though the control is set to manual mode, every morning when i start working, I find that the radio has switch itself back to one of the very busy channels and i have to login a switch back. It seems that in “manual” mode, it lets you select a channel, but it still does an audit every day and overrides your selection. Also, the view the WiFi’s view of channel use is different from my computers view. I would like to be able to force the router onto a specific channel and lock it.

I am trying to connect to my WiFi but unable to connect to both 2.4 and 5.When trying to sign in on the app, it tells me to connect to the networks but am unable to. My ethernet works fine, but can not figure out what to do.G34 w/ XFinity service

Hi, I recently used G34 to replace Xfinity’s own modem. However, I noticed the upload speed is dropping from 100 Mbps to 4 Mbps. So I am wondering what might be the reason? And how to fix this issue. Thanks,Yanghao

Help! I have XFinity internet, and their technical support team insists the problem lies with my modem/router. I’ve had an Arris G36 Gateway for less than two years, but for the last few weeks, my internet keeps disconnecting, and when it does work, it’s painfully slow. The XFinity rep said there could be missing or outdated boot files. Could that be correct? If so, how do I update them? Thank you in advance, sincerely. Signed, Noob.

My wifi status are showing all disconnected. When I try to start the 2.4G/5G radio, the dashboard says “Operation Failed”. I tried to do the factory resetting, it won’t allow me to set up the wifi name/password either. The error message is still “operation failed”. The wired connection works fine. Anyone has suggestions on how to fix this ?

I have G36 and with Xfinity provider the internet drops all the time, I have to restart the modem daily. I tried to contact support but no help from them. Regret buying G36

Recently upgraded to the G36. I was getting 900-950 download with the provider hitron unit. Now with the new G36 installation I am seeing 550 at absolute best hardwired directly to the modem. Firmware Version:01.04.028.01.01.NCS I called Sparklight technical and they said this currently the latest firmware that they can upload. I have attached some info. Any help would be greatly appreciated!

need a password for G34 modem

Isp says connection to g34 is good but when trying to access Internet through any device wired or wireless it says no internet access when logging in through my PC and going to the to the troubleshooting and then diagnostic tools and testing connectivity it says everything is okay. Packets are sent and packets are received just fine.

Got the G34 a few days ago, which I bought despite concerns, having read about how frequently it is a returned item to stores. I set it up easily enough and got laptops and cell phones connected without difficulty. I even managed to change the provided network password to something more easily remembered. And then the trouble begins. I have tried repeatedly to set up the connection between my Echo Studio and my network. No luck despite repeated efforts, including rebooting both the Echo device and the G34 on various occasions. I have some other simple devices, eg smart bulbs, fan/light, and they too, I have been unable to get onto my network. (Laptops and phones remained connected, or were easily reconnected after a reboot, during all of this time>) I previously used a Netgear C3700 and had no problems connecting any of my devices to enable their remote operation using Alexa on the Echo. I am at my wit's end and am already considering returning the G34. Please can anyone help, and advi

I’ve been experiencing the same drops others have been for the G36, but additionally I’ve been paying for 1200 mbps, but capping off at 900mbps. I’m connected via ethernet cable, and have done multiple hard resets. After spending an hour on the phone with Xfinity they said that they couldn’t do anything and I should contact the manufacturer to make sure I have the correct settings on the G36. I was wondering if there was some way to check that? (personally I think they were just trying to get me off the phone/avoid refunding me, but wanted to at least have the effort shown for argumentative sake.)

I seriously am losing my mind. I already have it on a timer so it reboots every single day, and yet while watching TV, using my phone, tablet, whatever, I get a “no internet” message or nothing loads multiple times a day. I can switch to the 2.4 GHz channel and that works. Sometimes I can get it to work again by turning wifi on and off on the device, sometimes I need to reset the G34. It is not a range thing, this happens when I am right by the G34, it just stops transmitting on the 5GHz channel. What on earth is making this happen? I have also changed the channels multiple times, it doens’t seem very congested where I am , I don’t think this is the issue. Firmware versions: 01.05.020.04.01.NCS
