What Our Clients Are Saying:
Excellent & Helpful
I feel Rene is very helpful especially when I need help in my job in Cisco. My previous experience is with Linux systems and any open-source projects, creating various services ranging from DNS, Web services to OpenVPN, and OpenRadius. Plus maintaining security of servers. I am currently working at a Stocks Exchange Software company, which requires me to have knowledge both in Cisco, and Unix. I have some basic knowledge on Cisco, however my job requires to have more in-depth knowledge especially in multicast. One thing I love in enrolling on Network Lessons is because of Rene, I feel he is a very helpful and talented Cisco Network Engineer. Hopefully I will learn a lot on Cisco and he may help me, since I started to love Cisco.

NetworkLessons.com has an amazing way simplifying complex materials without oversimplifying things. Nice drawings of the scenarios. I used their materials (and some other) to achieve CCNP level (RS) and am now using it to complement my CCIE studies. Their courses are ordered in a way that you can find answers to questions you got fast. I really recommend their materials!

Excellent, Fun and Valuable
A buddy of me told me about this website, so I gave it a shot. Since I changed job from System Engineer to Pre Sales, I have been asked to certify for CCNP and going trough the official Cisco certification guides is not only a hassle but sometimes you read on difficult subjects and the way it is explained is sometimes more difficult then it actually is. Regardless of your expertise, Networklessons.com provides the basics in a playful way and more. Difficult topics are brought in a easy readable format and looking at the whole package, including GNS3Vault labs, makes Networklessons a must have when you want to certify or grow in the job. It is fantastic that a person is so dedicated to help others on difficult topics. Keep it going René!
