About Me

My name is Renzo Notter, and I am born in Switzerland in 1993. After my 4-year apprentiship as a computer scientist, I started working as a Network Operation Specialist in 2013. Early on, I ended up with the task of “adminstering the Wi-Fi” by coincidence and without really knowing what’s behind all this in the beginning. I  acquired my knowledge via “Learning by Doing”, which, in retrospective, left me with some fundamental gaps I whish I would have been able to fill in earlier. After 3 years, I was given the chance to start working as a Network Engineer,  and decided to educate myself , because I wanted to truly unerstand every bit and byte in the world of Wireless LAN – so I went full-nerd for more than half a year, and read through every book, article, blog-entry, forum and tutorial I could find. While doing that, I went on the CWNP-adventure, that took me through the tests CWTS, CWNA, CWDP, CWAP, CWSP.

So here I am now, with the 5 certificates in my pocket and the will to go further – there is still so much more I want to learn about this great technology.

With this website, I want to contribute a small part in the world of the 802.11-community. My goal is not to write about topics that are already covered in great depth on other websites by awesome specialists, but to write about problems and ideas I stumbled accross myself where I was not able to find the solutions or in-depth content anywhere.

If you have any questions or inputs, please do not hesitate to contact me through Twitter, Mail, LinkedIn or Xing.

Cheers, Renzo
