CWNE Journey

// wireless network engineer
CWNE has been on my list since I passed my CCIE Wireless back in 2018. Life just had other plans for a while.
I started a company, became a dad, and somewhere in between, structured study time stopped being a thing. Not because I lost interest, just because there are only so many hours and a lot of them were already spoken for …

CWNE Journey
From Theory
to Real-World
Wireless!
This is not just study material.
We document real scenarios, troubleshooting cases, and design decisions from actual deployments and lab environments.
A curated collection of books, tools, communities, and training materials that have been valuable on the path to CWNE.
Practical guides, tools, and techniques for diagnosing and resolving wireless network issues.
Technical write-ups on wireless networking topics, from RF fundamentals to protocol analysis.
Fun Wi-Fi related projects and experiments. Down the rabbit hole we go.
Three technical essays required for the CWNE application, each describing a real-world problem solved on a project.

Diagnose Any Wi-Fi Problem with netsh wlan report
When a Windows device drops off Wi-Fi, roams at the wrong time, or silently fails an 802.1X handshake, the fastest path to root cause is almost always the same command:
netsh wlan show wlanreportThis generates a self-contained HTML diagnostic report saved to…
Stadium Wi-Fi Recovery and RF Performance Stabilization
In the lead-up to the 2021 soccer championships, I executed a full WLAN recovery at a major stadium following the abrupt removal of the guest access platform due to a commercial dispute. The underlying Cisco infrastructure, including external-antenna P-model APs paired with AIR-ANT2513P4M-N dual-band patch array antennas, remained in place. The service was entirely non-operational. Failures existed across three independent layers: ….
