Wireless Adjuster Course (Level II)

The instructor will use WiFi Explorer Pro (MacOS only) for instruction, so using a MacBook and WiFi Explorer Pro is highly recommended.

  • If you are using MacOS Catalina, please upgrade to the latest version (due to Wi-Fi bug fixes). If you are using a MacBook Pro 2018 (15-inch), contact me for additional information.
  • Students that use Windows 10 may use MetaGeek’s inSSIDer, WinFi, and/or Acrylic WiFi Professional, though all are currently missing some important features.
  • We also recommend that students that intend to use Windows-based scanners familiarize themselves with those scanners before class.

For ONLINE classes, students will not need the WLANpi or DBx adapters. Note that students using WinFi are not currently able to connect remotely into the live labs, so they will use preconfigured captures instead.

Wi-Fi networks can be complicated. The 802.11 protocol is complicated. Understanding how to use inexpensive WLAN scanning tools to quickly and efficiently assess and remediate the first 80% of WLAN connectivity, performance, and security problems will save your organization an enormous amount of time and money. This course pays for itself the very first time your WLAN experiences a problem due to best-practice misconfiguration. If you are a consultant, this course will make you more money than any other in the Wi-Fi market. In this course you will combine knowledge of the 802.11 protocol, RF spectrum, amazing new WLAN scanning tools, and detailed troubleshooting processes. This course is 75% lab time, uses the newest analysis tools, and guarantees to catapult you forward in WLAN troubleshooting in only two days.

ITEMS TO BRING TO CLASS:

  • Macbook running MacOS (very recent version) or a Windows-based laptop running Windows 10
  • WLANpi with Comfast CF-912AC (or other compatible) WiFi adapter
  • USB hub
  • OPTIONAL: MetaGeek DBx adapter (bring yours if you have one)

Contact me at Devin[at]DivDyn.com for hardware discount information after class registration. We have a small number of spare WLANpi and DBx adapters in case you cannot provide your own, but please bring your own if possible.

FAQ

There is a large variety of WLAN analysis tools available in today’s market – many expensive and complicated. The Wireless Adjuster course is designed for WLAN engineers and technicians and focuses on WLAN best practice assessment/remediation and the first 80% of troubleshooting tasks. How many times have you been asked, “can you just take a quick look at my WLAN to see if any obvious problems stand out?” That process is an assessment. Of course, if you find problems during an assessment, a network adjustment may be needed to remedy the deficiency. Hence the name “Wireless Adjuster.” If you have solved a WLAN problem with a WLAN scanner, not needing to use protocol analyzers, spectrum analyzers, RF site survey/design software, or other sophisticated tools, then you already know what this course is about. The difference is that this course includes advanced discussions and uses of WLAN scanners and others tool that directly integrate with them. This course includes in-depth discussions and advanced-level uses of WLAN scanners and tools integrated with them. The Wireless Adjuster course will take your practical WLAN troubleshooting skills to an entirely new level of efficiency and accuracy. 

There is a significant gap between the theory of IEEE 802.11 protocol analysis and its practical application in WLAN best practice assessment/remediation and troubleshooting. Analyzing millions of 802.11 frames is unnecessary in 80% (or more!) of WLAN troubleshooting scenarios. A more practical tool, the WLAN scanner, is not only sufficient, but far more efficient at sorting, filtering, and finding needles in haystacks. This course also teaches when using a WLAN scanner is most appropriate, verses using other WLAN analysis tools. Industry-leading tools from vendors such as Ekahau, iBwave, Tamosoft, AirMagnet, NetAlly, MetaGeek, NutsAboutNets, and others are valuable and important, but their use may often be 20% or less of the overall assessment/remediation and troubleshooting process. Don’t misunderstand – it’s not an “either-or,” but rather a “both-and” when it comes to these tools. However, engineers reach for the “Swiss Army Knife” WLAN scanner far more than they reach for their chainsaw in assessment/remediation and troubleshooting processes. If you want to understand a WLAN’s health in seconds, the WLAN scanner is the first (and sometimes the only) tool to pull out of your tool bag. 

Learning to effectively use a WLAN scanner can save you many thousands of dollars on complicated, unnecessary WLAN monitoring platforms. The Wireless Adjuster course ensures that engineers maximize the value of their WLAN scanner, enabling them to quickly assess WLAN deployments and to take the most appropriate security and performance remediation steps.

The Wireless Adjuster course also focuses on minority use cases for WLAN scanners, such as how they can act as a low-end Wireless Intrusion Detection System (WIDS) or WLAN performance monitoring system. This is true for a single location or a distributed enterprise, and WLAN scanners may also be used to do on-going best-practice and change-management monitoring across enterprises. You will learn all of these approaches in this course.

LEARN: Best practice assessment, appropriate and expedient remediation steps, and efficient troubleshooting across three WLAN knowledge domains: 1) connectivity, 2) performance, and 3) security. This course will sharply hone students’ observation, analysis, and optimization skills.

DO: There will be a short presentation and lab prep work at the beginning of the course. This will be followed by WLAN scanner (and integrated tools) familiarization labs (including 802.11 protocol analysis within the WLAN scanner). The next step is a series of “canned” labs that help the student get more familiar with the WLAN scanner and its use in the troubleshooting process. Finally, there will be a series of LIVE LABS where the instructor configures a variety of “Bad-Fi” scenarios, and students are tasked find the WLAN deficiencies. This will be the most useful WLAN class you have ever attended – guaranteed!

While WLAN scanners are considered “low-end” WLAN troubleshooting and assessment tools, they are anything but low-end. Most technicians and engineers who own a good WLAN scanner know very little about:

  1. optimal use of the WLAN scanner in best-practice assessment/remediation and troubleshooting
  2. the entire feature set of the WLAN scanner (and how those features can help in specific scenarios)
  3. alternative uses of the WLAN scanner, and 4) integration of various other low-cost tools (e.g. WLANpi, MetaGeek DBx, etc.) with the WLAN scanner.

No. The Wireless Adjuster course and certification fill a large educational gap in practical knowledge of troubleshooting process, best-practice assessment/remediation, and protocol analysis in the Wi-Fi industry. The Wireless Adjuster program is complimentary with other existing WLAN training and certification programs.

The recommended prerequisite knowledge for this course is on-par with the CWNA certification, though the certification is certainly not required for attendance. Recommended reading may be found here.
