Wi-Fi name changes on its own and unable to access internet with VPN on G34

My network name keeps changing over the last week, without me doing anything. It changes back to an old name or all of a sudden it has a number 2 at the end of the name. Why? I have a G34 WiFi modem.

Can't connect G36 to Xfinity

I am trying to replace my Xfinity cable modem with a G36 but am unable to successfully connect it to the Xfinity network. I tried the self activation using Xfinity’s app and the HFC MAC (both manually and with the QR code) which did not work and then talked with an Xfinity live agent for about 3 hours but still no luck. They say they can see the modem but when I’m on the admin app there is nothing showing in the WAN and signal screens. I factory reset the modem, power cycled, etc. multiple times with the Xfinity agent but nothing worked. I am able to switch it back to the old Xfinity modem and it works fine. The only recourse I have with Xfinity is to have a tech come to the house which will cost $100 but that seems useless since I know the signal is good (because the Xfinity agent switched the MAC back to the old cable modem and it works fine). The problem is definitely the G36. It just flashes blue. Is there any recourse?

G34 secondary wifi not working

I am having problems with my G34. I have it setup with the primary wifi as default name. I have the secondary wifi setup with a custom name. The guest wifi is not used. For some reason the modem will quit broadcasting on the secondary wifi. It will not even show up on the list of available networks. If I go into the setup my setting are still there. Power cycle does not fix it. The only way to make it work again without a factory reset is to disable both the 5ghz and the 2.4ghz. Save the settings. Then go back in and enable both 5ghz and 2.4ghz. Then the modem will broadcast the ssid and work again, This happens every week to 10 days. Any clues as to why this is happening? Thanks Bill

cant keep connection with new g34

I got a new gateway to replace the old one hoping for some quicker speeds and longer range. I called xfinity to activate because the self activate would not work. It wasn't recognizing the hfic. I finally got the wifi to show up on my devices but it shows no internet. Then after about 10 minutes it disappears completely. The front light is a solid blue. None of the ethernet jacks light up. And I tried plugging my computer straight into it with no recognition that it is connected. Is this gateway junk or why can I not connect to it directly?

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.

Troubleshooting with G54 Bridge Mode

Hello, I need some help with my G54 modem. Network: My G54 will act as my bridge, my UDM Pro will handle assigning IP addresses to devices. I will be setting up VLANs on a switch and I’ll be using mesh nodes for AP (replacing repeaters.) Issue: When I enable Bridge Mode on my G54 and restart it, my connected Router does not recieve a WAN IP, only a LAN IP. When Bridge Mode is disabled, I have both on my UDM Pro router. I have been factory restting my G54 to recieve internet access/connection when this fails. When I connect my laptop to G54 (in bridge mode) my laptop is assigned a 169. IP but when I connect to the Router (while G54 is in bridge mode I get a 192. IP, but I do not gain internet access.) Troubleshooting attempts: I tried cloning the MAC address assigned to my laptop, it recieved from the modem, to my UDM Pro’s WAN1. (in the app.) It was unsuccessful. I tried to manually push a working IP address. Awful attempt. Unsuccessful. I called my ISP and asked them to enable Bridge

All of my devices are hard wired. Can the WiFi be disabled, or does the router not broadcast if there are no devices connected wireless?

Port forwarding to internal hosts with the same port number

Hello, I have a client who recently had Comcast install a new cable modem (CBR2-T) and this broke their credit card machines. Long story short the new Comcast Cable modem cannot forward different incoming requests on different ports to different internal hosts on the same port. The old cable modem could do this! Basically, I want to do this: 78.100.200.50:6000 → 192.168.1.10:6000 78.100.200.50:5999 → 192.168.1.11:6000 (IPs are for example purposes only and not real) The Arris G54 is listed as an approved Comcast cable modem and before I have the client purchase it I want to be sure the port forwarding will work as I described above. Thanks, Jerry

Arris G34 high ping spikes / Puma CPU Related?

I bought an Arris G34 about a year ago and have had mediocre internet assuming it was the ISP because I live in a poorer neighborhood. I recently finished a remodel and had all new COAX installed ( RG6) through out the house to include two CAT6 lines to every room. It wasn’t till I got a roommate who complained about constant internet drops and high ping spikes that I investigated more. My signals are good and this was confirmed by Spectrum. My ping is all over the place and this is confirmed by two different stability tests. Some spikes are over 1,000 ping. Spectrum does list this router/modem combo as approved Spectrum has also issued the most recent firmware for this product. I am aware of the PUMA CPU lawsuit and issues with the Intel PUMA CPU. These ping spikes are reflected on both Ethernet and Wifi for all products connected to this modem/router combo. In fact my wifi hotspot from my phone provides more stable internet connections and comparable speeds referenced below. I am sti

G36 boots wifi off every 5-10 minutes Xfinity

I have the G36, got it in august 24. It worked fine for about a month and then it started having problems where it would physically restart 2-3 times a day. Then in december it seemed to have fixed itself, and up until early february it worked fine. However now the router doesnt even restart itself and it just kicks off the internet for 5 of seemingly every 10 minutes.

Why are multiple G54’s not working on Xfinity?

I recently sent my last Arris G54 in because Xfinity said it didn’t work (after about 7 months of working flawlessly). After receiving a replacement, I setup another Xfinity Tech Appointment. The Tech took almost an hour trying to get the replacement to work, but it also can’t get a signal. Could it be that the replacement Arris sent me was also defective? Or is Xfinity trying to swindle me into paying for a rental? At this point, I don’t know what to believe.

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.
