Our take

Based on the ratings of 961 students, a sample of their written reviews and the syllabus, as the course stood in January 2025. No course pays to be reviewed.

This is a basic, practical networking course aimed at home and small-office setups. Marious Kuriata, who lists 20 years in IT and Cisco and Microsoft certifications, walks through routers, port forwarding, Wi-Fi troubleshooting, a Synology NAS setup, an Asus 802.11ac router lab and extras like Windows Server and WordPress hosting. It runs 8.4 hours over 81 lectures. Despite the Cisco mention in the title, it is not a CCNA course. One reviewer says it skips heavy theory beyond addressing and subnets.

Students like how clearly the material is explained. One reviewer says the instructor knows the subject, and another praises the video and audio quality and says it helped them choose a router while studying for CompTIA A+. The most common complaint is the legacy material. The syllabus shows roughly five of the 8.4 hours sit in sections labeled legacy. Reviewers say they were unsure why it was there, or annoyed it is needed to finish the course, and some of it is outdated. Others found the first half or more very basic.

Last updated in January 2025, it still does what it sets out to do. Treat the legacy sections as optional extras, though the completion tracker may push you to watch them. It suits beginners and curious home users well. Anyone chasing a certification should see it as a light warm-up, since there are only three quizzes and no practice tests.

Best forHome users who want to set up a router, NAS, IP camera or better Wi-Fi without wading through networking theory.
Skip it ifYou need CCNA-level depth or a structured exam prep path with practice tests.

Pros

  • Practical home topics: port forwarding, dynamic DNS, Wi-Fi tuning, NAS and IP camera setup
  • Light on theory, so a complete novice can follow along
  • Reviewers praise clear explanations and good audio and video quality
  • Includes a hands-on 802.11ac Asus router lab and a Synology NAS setup

Cons

  • About five of the 8.4 hours are legacy sections, and some of it is outdated
  • Reviewers call the first half or more very basic, with little for those who know networking
  • Only three quizzes and no practice tests, so weak for exam prep
Simple, practical, and easy to grasp. This is a good start as a complete novice, or a good refresher for those who might have been around in the IT world for some time.
Terrin Scott, a student

Beginner is accurate. It assumes basic Windows and internet knowledge, and a test router helps.

overall, content was great. Well-presented and made easy to understand. It was annoying that after the current materials were completed, I was forced to go through all the bonus materials, much of which is outdated, in order to get full "credit" for completing the course. Bonus material should be optional.

By Andrew Fawcett on 4/2/2020

This is a very comprehensive course that introduces a lot of networking topics without getting bogged with a lot of network theory. There's a little bit of theory to explain network addressing and subnets, then the rest of the course covers different networking technologies and how they are used. The tutor knows the subject and explains things clearly. I learnt a lot and found the information interesting.

By Eugene Stevens on 9/10/2018

Yes, great very informative. Excellent video's and audio quality! Looking forward to higher learning with same instructor. Excellent presentation. Thank you very much. Currently preparing for CompTia A+ exam. Now, have a much better understanding of functions and features of a router. More importantly, choosing the best one for my needs.

By Brian LaVerghetta on 3/27/2018

Excellent tutorial on home networking with in depth descriptions and tools to expand your knowledge. This course covers a large amount of information. From the basics like the differences between switches and routers to more complex practices such as server maintenance, Port Forwarding, and Firewalls.

By Widmietredath Ishwardat on 12/30/2017

Dit heb ik altijd willen leren,maar wist niet waar te beginnen. Thank you Udemy Team! Ik ben heel blij met de cursus,ik beschik over al deze apparaten wat ik nu in praktijk kan toepassen. Ik zal contact met deze instruteur bilijven behouden, ik heb veel geleerd en ben hem heel erg dankbaar.

By Russ Carpenter on 8/24/2017

Through the first half of the course, it's really intended for someone who knows almost nothing about a network, and how to set it up at home. There are some good tips/tricks along the way, but still pretty basic overall through the first two-thirds of the course. The latter third does get more involved, and more interesting. I would have also liked this to give a comparison of Windows/PC networking relative to UNIX.

By Charles Hall on 7/17/2016

Instructor is very knowledgeable and at times humorous. I actually enjoy his accent. He clearly knows his stuff. The course was relatively short, but I purchased it at a discount, so it was worth the money. I would not hesitate to buy other courses by this author.

By Quinten J. Bailey on 3/15/2016

As I have learned from other courses from Marious Kuriata, he presents a technical subject in short videos very clearly until the whole subject is completed. For an introductory subject this style of teaching has helped me learn enough to pursue more advanced courses with confidence.

By Bo Washington on 11/29/2015

I already had some basic knowledge of wired networking fundamentals but needed to get a better understanding of wireless networking and firewalls and this course gave me the information to make changes to my home network setup to strengthen the security of the router and firewall.

By Peter Stampede on 7/20/2015

I enjoyed this course, and found it to be a great overview of the world of IT and Network Engineering. Currently my job involves a lot of network related duties for testing IP products, but I have not previously had much exposure on these topics. I purchased this course to help bring me up to speed on everything I should basically know. I found a lot of good tips, good review of networking terminology and concepts and I appreciated the experiences and anecdotes shared by Marious. The discussions are great and I got great constructive responses. I'm going to miss staying up late watching these videos on my iPad. Thanks!
