Surfboard SBG7400AC2 Disable Wi-Fi Networks

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.

SBG7580-AC WPA2 and KRACK

I have an SBG7580-AC wifi gateway running firmware {edit : personal information} (Xfinity is my ISP since a few months ago.) Does this firmware version correct the WPA2 security vunerabilities exploited by KRACK or do I need to acquire another wifi gateway model that supports WPA3?

G36 exisits? Upgrade firmware or replace for slow speed

I have a G-36 DOCSIS 3.1 for about 14 months. It’s been working FAST on Cox. However, the past few weeks it’s dropped speed from 550MPS to under 30MPS. COX says it’s an old, outdated modem and want to sell me their own. WHAT? I need to be able to customize port forwarding and other features that if I get a COX managed modem I won’t be able to do that. Is there a firmware updates for this modem? I have read that the updates are ‘automatic’ and some folks experienced a downgrade in performance. How can I tell if my G-36 updated the firmware and what revision should it be at? If NOT, then what’s a good replacement that won’t be obsolete in 15 months?

unable to connect security system phone line to SGB8300 surfboard

Does model SGB8300 have a port to support a phone cable connection to connect our landline phone with our home security system? An ethernet cable was included in the box but I’m unsure of what it is used for.

G36: MOCA not working after replacing cable modem

Hello, I have 2 MOCA 2.5 Motorola adapters installed for years and my cable modem was a Motorola MT8733. One MOCA adapter is connected to my modem in the living room, and the other is in my office upstairs and everything worked fine. My 8733 started having problems that requested me to reset it every other week and today I replaced it with a Arris G36. Wifi is working fine, but the Ethernet adapter in my laptop (connected to a MOCA upstairs using a network cable) has no connection - connection was great when I had the MT8733. I reviewed pretty much all config pages in the G36 and couldn't find something that needs to be configured to make the MOCA connection work. Thoughts? Is there a configuration I would need to change? Should I use a PoE filter? PS: the LEDs on both MOCA adapters behave the same as before, so it's not a link/LAN connection issue.
