What I Took Away From the Wireless Adjuster Course

This course comes from Divergent Dynamics, taught by none other than Devin Akin. I have been following the story line of Wireless Adjuster since before it was unleashed, and here is some background if you have any interest:

Now that I have actually sat through the two-day course myself, let me share my impressions.

Wireless Adjuster Fills a Need

There is vendor training out there for wireless networking, and there is the excellent Certified Wireless Network Professional (CWNP) program (reminder that I am CWNE #200 and current member of the CWNE advisory board). But I have yet to see a really good, practical, hands-on training course that looks to equip a broad cross-section of wireless troubleshooters with the mindset and experience to use tools that almost anyone can afford to find perhaps 90% of likely WLAN-side problems.

Wireless Adjuster Complements Other Courses

Regardless of your past training and proficiency with wireless analysis (like CWAP), survey tools (like Ekahau) and basic foundational knowledge (vendor training, CWNA), Wireless Adjuster re-enforces and introduces some pretty key best-practice (and exceptions to best practices) philosophy for a range of WLAN situations. Combine what you get out of Wireless Adjuster with what you already think you know, and you’ll be living larger as an analysis professional, I promise.

Wireless Adjuster Shows Just How Powerful WiFi Explorer Pro Really Is

WiFi Explorer Pro is already widely appreciated among WLAN professionals as an easy-to-use, huge-bang-for-the-buck WLAN analysis tool. It doesn’t NEED to be the main tool used in Wireless Adjuster to gain recognition, but the way it is used in the course will make you appreciate WiFi Explorer Pro even more. Devin does a nice job introducing aspects of the tool you may not be aware of, and uses it as a bona fide troubleshooting suite that competes with any tool out there. When you consider the integrations supported with MetaGeek’s dBx adapters, WLANPi, and other external devices, it’s fairly mind blowing that WiFi Explorer Pro can be had for under $100. To me, this is the best value out there among WLAN support tools.

Wireless Adjuster Exposes Just How Defective the WLAN Standards Are in Spots

I would love for anyone involved with developing 802.11 standards and the entire Wi-Fi Alliance staff to sit through Wireless Adjuster. Throughout the class, you’ll see example after example of how optional parts of the various standards cause a lot of performance problems in various WLAN settings. You see real-world examples of the cost of the IEEE 802.11 groups being hung up on backwards compatibility. You learn why many of the sexy, hyper-marketed aspects of 802.11, .ac. and .ax sound great in promotional material, but flat-out suck in the real world. Devin finds fault with none of it, and is far more of a gentleman about it than I am. He methodically and objectively guides you through this odd reality through real live examples that you analyze for yourself.

Having taken Wireless Adjuster, I’m now even more taken aback than I have ever been  about how out of sync with reality the IEEE 802.11 folks, the Wi-Fi Alliance, and many WLAN vendors are with real-world WLAN performance. It’s pretty freakin’ unreal, says I. Don’t agree? I’ll fight you, and I’ll fight dirty.

Wireless Adjuster Is Fairly Captivating

I will freely admit that I am a far better instructor than I am a student. I have a recognized track record of being good at teaching, dating back to my time in the US Air Force instructor school. But put me on the other side of the equation and I get bored easy as a student. I daydream. I doodle. I multitask, and do a fairly poor job of it. But for the almost twenty hours of Wireless Adjuster time, I was pretty much riveted. The discussion was fantastic, the examples are relatable, and even though I’m a certified “expert” I learned once again that I don’t know it all. Wireless Adjuster commanded my attention (despite taking the course remotely), and I finished the training with a todo list of things to go examine on my own networks.

Final Word: Time Well Spent

When it comes to technical training, I want VALUE. I don’t want to spend a day getting a half-hour’s worth of actionable information. Wireless Adjuster hits that sweet spot where newer wireless folks and vets like myself can both benefit greatly from the materials, the exercises, and especially the discussion throughout the course. I’m glad I took the class, and I highly recommend it.
