Basic intro on how to do a wireless (Wi-Fi) packet capture on Windows, on the cheap, using Wireshark 3.0 and the Netgear A6210. IMPORTANT STUFF!👇
01:54 - Wireshark installation particulars.
04:01 - Supported NICs
07:05 - Putting NIC in RF Monitor Mode
09:31 - Setting the channel to capture on
IMPORTANT! You MUST install the Netgear drivers, to you will not be able to capture on any UNII-2 channels. Download the drivers here - https://tinyurl.com/y23xdl3r
The first in what will be a regular set of videos on Wi-Fi related things. To start things off: a series of videos on packet capture and analysis.
Ep. 001 is a basic intro on wireless packet captures, on a Mac, using Wireshark and Adrian Granados' Airtool.
Ep. 002 will be on doing the same thing, but on Windows! 😱
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!
The great Michael Peńa.
Here’s that actual .pcapng file for your use.

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.

All of @MisterMultipath‘s blogs posts on 11ax are gold, Jerry! GOLD!
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.
“It was last year when I first read/ discovered about 802.11ax on one of the websites mentioned below as references. Ever since I tried to collect more information and wanted to write about the same. But every passing day/ week/ month, I learnt a new aspect about 802.11ax. Being from Telecom Industry and Radio background, “throughput/speed/data rate ” makes us go ga-ga. Even if anyone ask us difference between 802.11ac vs ax or 3G vs LTE/4G first thing we point out is higher speeds.
But honestly, 802.11ax is much more than only speed. It is complete evolution or shall I say the moment for Wi-Fi Industry. When I started reading about MulteFire, LTE-U/LAA in the same spectrum, was bit worried about Wi-Fi and future as Wi-Fi as technology was designed for neutral environment and didn’t have sophisticated Interference mitigation from external sources. Then came the moment with 802.11ax, the features have made me believe again, Wi-Fi is here to stay and would play greater role in Future Networks, more than enterprise and indoors.”

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.
Apple was kind enough to provide this information for iOS.
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.
