In case you missed my WLPC Wireshark talk here’s the 802.1X process file… with COMMENTS.😬
It’s just the specific frames in the 802.1X process saved into a separate file with comments for each of the frames. Hopefully, it will give an decent understanding of what is actually happening during this process. ENJOY!

WLPC 2019 is upon us and I’m off to Phoenix, AZ. But, first, I got a little shoveling to do. ❄️
Looking forward to seeing all my fellow Wi-Fi nerds and learn some stuff!
I’ll be presenting this year with a short talk on my favorite Wireshark customizations. Nothing too exciting, but hopefully some folks Weill get something out of it.
This will be the first year I will be going to both US AND EU WLPCs! I am really looking forward to my first WLPC-EU where I will be teaching the ECSE course.
I have plans for this year to start putting up more content on a regular basis. Working through some stuff the last few years and I am coming out the other end.
So, #WLPC Peeps, I’ll see you soon! And those of you who couldn’t make it, I hope you’ll be able to do so in the future. I miss you. 😢
For those of you who are trying to decide if it’s worth it, you can view video from ALL the previous WLPCs on their YouTube channel.
I’ll like to tell people that what I REALLY go to WLPC for is the community. Hanging out with folks, making new friends, sharing knowledge, and learning from some VERY smart people.
Videos are great, but PEOPLE are better.
And here’s a detailed whiepaper on 11ax from National Instruments.

Ooooooh… this looks nice. Besides looking pretty and offering PoE+, to ALSO has: 12v barrel connect out, and 5V USB out. Now, if they would only add 100W USB-C out. 😏
Good read from TechPlayOn. It’s short and to the point and outlines the differences between 11ax and LTE which has been using and reaping the benefits of OFDM-A for years.

Knowing is half the battle. Understanding how your devices make decisions helps you determine design requirements to build better WLANs. Here’s documentation on how Apple and Samsung devices make roaming decisions.
macOS & iOS Wireless Roaming for Enterprise
Apple was kind enough to provide this information for iOS.
Samsung Knox Roaming Algorithm
Knox is an Enterprise platform for Samsung devices that offers enhanced roaming. Learn how it works to help you support it in your wireless designs.
As a BONUS here’s Apple’s iOS Deployment Guide too!

I'm asked all the time how I travel with just ONE bag. So, I made a video!
I am currently on an Around-the-World trip going from Denver to Abu Dhabi to Bangkok to Gold Coast, Australia then back to Denver. This will be about a three week excursion teaching the ECSE Design Course. I have brought one bag for all my items.
I do this for a few reasons: 1. I refuse to check anything. So, I never have lost luggage, 2. I like to move fast. Get through lines fast. Get to my transportation fast - one backpack makes this super easy to accomplish.
DISCLAIMER: On this trip I actually have two bags. One is for all my stuff, the other is for carrying stuff while I am out and about doing touristy stuff. My travel bag on this trip is the Goruck GR2, a 40L backpack. It's way to big to use as my EDC (every day carry) so I did bring my 5.11 Rush10 for day-to-day carry.
So, here is a video I made in my room in Abu Dhabi showing what's in my bag.
