Wireless Adjuster II – 2022

Wireless Adjuster II – 2022

This past week I attended the Wireless Adjust II class taught by Devin Akin. I recall attending the very first class back in 2020, that was a beta class, and we all had a great time attending that class. You can read more here.

I knew that Devin had added lots of new content in the class and there were lots of exciting updates in the course since 2020, so it excited me to sit in the class again.

Other than the course itself, it was a prefect time to be in the class because Peter Mackenzie, who is an absolute genius for wireless captures and analysis, was also in the class. As I mentioned in my original post, that engagement and discussions with the industry professionals and getting deep into technology, real-world examples are an amazing part of this class.

Primary object of the class is train WLAN Engineers with a deeper understanding of all WLAN best practices; which will give them skills to do an assessment and adjustment of a WLAN. Use lower cost tools before having to pull out expensive WLAN assessment gear.

There are at least 48 WLAN Best Practices in the course that we discussed. Each best practice involves deeper dive, discussion, understanding the technology/standard. Will turning a certain option on that a vendor tells you to turn on actually make your WLAN better or will it make it worse? Debunking some marketing terms and if you should follow them or not.

Some of my favorite discussions were about Wi-Fi 6E, OFDMA, MU-MIMO, NDP frames, Tx Beam forming, Rx SOP, etc.

Since I am a Mac user, I was using Wi-Fi Explorer Pro from Intuitibits. I really thought I knew the app well enough since I have been using it for a while and I have taken this class previously; that was a wrong assumption. I certainly learned a few new tricks, especially since Adrian has added a bunch of new cool features in the latest version. If you are a WLAN Professional and/or manage a wireless network, I highly recommend this app.

Canned Labs were fun, very hands on, using actual pcaps to analyze the data and then figure out the solution to the problems. Labs were highly engaging and really help you understand your WLAN troubleshooting skill-set.

If you are a CWNE and/or have taken your CWAP, CWDP, CWSP tests, this certainly gives you a good refresher on some of the topics.

So what did WA II class do for me? Or what benefit did I get taking this class?

  • I improved my troubleshooting skills since the very first time I took this class.
  • Better understanding of some complicated topics when it comes to analysis and design.
  • I learned how to utilize low cost WLAN assessment and troubleshooting tools in creative ways.
  • Improved skills to troubleshoot/find root cause of WLAN performance issues remotely. (I have been very successful utilizing Wyebot as a remote sensor.
  • Provide better value to my clients when creating reports for them and give better presentations.
