NetworkChuck
NetworkChuck is Chuck Keith, an IT educator and CBT Nuggets trainer since 2017, per CBT Nuggets. His channel teaches networking, cybersecurity, Linux, and Python — and how to turn certifications like the CCNA into an IT career — in a loud, hands-on, build-it-yourself style. SGV distills 372 of his episodes here.
networkchuck.comNetworkChuck is the online persona of Chuck Keith. CBT Nuggets, where he has been a trainer since 2017, tells his origin story plainly: he started his own IT career with training from CBT Nuggets, earned his Cisco and CompTIA certifications through guidance from its trainers, and in 2014 started the NetworkChuck YouTube channel, shifting its focus toward IT career and certification preparation advice. CBT Nuggets lists his certifications as CCNA R&S, CCNA Voice, and CompTIA Security+, and his areas of expertise as Cisco networking and collaboration.
The teaching itself is the opposite of a lecture hall. The signature series are full free courses hiding inside the channel — the Free CCNA run from “What is a Network?” through subnetting, TCP/IP and the OSI model, and hybrid cloud; “You Suck at Subnetting” as a drill sergeant franchise; “Linux for Hackers” and “Python RIGHT NOW!!” as build-along tracks — surrounded by project videos where he builds the thing on camera: a Raspberry Pi hacking lab, a home server room, a dark-web site, a phone system, an AI supercomputer out of Mac Studios. The newer library leans into AI tooling, homelab automation with tools like n8n, and local, private AI setups, without dropping the certification core.
His official site, networkchuck.com, frames the mission as career entry: whether you want to become a network engineer, a hacker, a cloud engineer, or just know how to get started in IT. The business around the teaching is the NetworkChuck Academy, his own training platform for networking and cybersecurity courses, and his official store — coffee and merch included, because coffee is part of the brand’s running joke about how IT people actually study.
