Let’s Use Our Coax Smarter Pandemic

Mia Colabrese2020-09-15T09:08:47-04:00September 15th, 2020|

Let’s Use Our Coax Smarter It’s there and you already paid for it I often hear from subscribers and they ask me about why their network connection is so terrible. When they contact me, they are very frustrated and angry and are confident their cable operator is doing this on purpose. I always stress to them that cable operators really do want them to have a great experience and great service. With that, a reliable network is even more important now than in any time in our history.

How to fix your Coax and Internet

Mia Colabrese2023-02-17T18:35:20-05:00July 14th, 2020|

How to fix your coax and internet. I have previously discussed that coax cable is really fragile. To some this can sound crazy because we hang coax cable in the air, burry it in the ground and run it through walls. It gets driven over by cars and walked on by people. So why do I say its fragile. Let me explain in a little more detail. I am Brady Volpe, Founder of The Volpe Firm and Nimble This. I have nearly 30 years experience in the broadband and

Troubleshooting Your Cable Modem

Mia Colabrese2021-08-18T10:36:32-04:00June 15th, 2020|

Troubleshooting Your Cable Modem is possible. Did you know your cable modem has a hidden user interface? Do you know all of the data in that hidden interface can help you make your home Internet more reliable and even faster? I’m going to walk you through logging into the cable modem interface and detail what that gibberish means, but first. Please note do not abuse this functionality. If users abuse this the functionality can be taken away so only use it responsibly and respectfully. It is frustrating to not have

Supporting Subscribers During a Pandemic

Mia Colabrese2020-06-03T09:23:15-04:00May 26th, 2020|

Imagine a time when subscribers want your service very badly because they are trapped in their homes, but there is a catch — they don’t want you to enter their homes to install the service or fix problems. Oh wait, we have been there, done that. COVID-19. No one saw the global pandemic coming and no one was prepared for the new world of social distancing, however, it’s here and it’s time to adapt. Self-installation — a different way One approach to supporting subscribers would be to simply

DOCSIS 4.0

Mia Colabrese2020-05-18T11:03:39-04:00February 20th, 2020|

Evolve or Die: Can DOCSIS 4.0 Compete with Fiber? The Telecommunications Act of 1996 forever changed the cable industry. It allowed cable and telecom to directly compete with each other. Data-Over-Cable Service Interface Specifications (DOCSIS) was already in development which enabled the cable industry to provide high speed data and later voice-over-Internet protocol (VoIP). It has been over a 20-year competition between telecom and cable operators, one that the cable industry has done quite well with and the telecom industry has struggled to keep up. The question we face is

Cable Haunt: Exploiting DOCSIS Modems

Mia Colabrese2021-12-15T10:13:01-05:00January 21st, 2020|

*Updated* (see patch for Cable Haunt at end of post) Cable Haunt is the fancy name given for a vulnerability recently disclosed by a group of researchers at Lyrebirds in Denmark exploiting DOCSIS modems. Cable Haunt affects cable modems using the Broadcom chipset specifically having the built-in spectrum analyzer many of us in the industry are quite fond of. Typically the forward path spectrum analyzer or Full Band Capture (FBC) analyzer in the broadcom chipset is used by the industry for proactive network maintenance (PNM) applications to
