Starting with iOS 16, Apple enabled users to display the password of Wi-Fi networks using pre-shared keys (PSK). While this feature can be useful for retrieving a forgotten PSK, a customer recently asked me how we could disable this feature. If you are not yet using 802.1x authentication for your mobile devices (which you should!) […]
Lately I have been deploying several Juniper Mist infrastructures and, for most projects, the built-in captive portal feature inside Mist offers a great solution for guest networks (when you need to rely on a captive portal). The need for logging In France, we have some strict regulations and laws regarding Open Wi-Fi networks through which […]

[FR] Démystifions le MIMO
Véritable rupture technologique pour le Wi-Fi à l’époque, le MIMO est une technologie apparue pour la première fois avec le 802.11n (ou Wi-Fi 4, sorti en 2009). Cette technologie évolue encore aujourd’hui pour améliorer les performances de nos réseaux sans-fil. Je vous propose dans cet article un aperçu technique des fonctionnalités permises par le MIMO, […]
Lately I have been working on implementing and testing OpenRoaming with different Wi-Fi vendors. If you don’t know about OpenRoaming, it is a global initiative from the Wireless Broadband Alliance that simplifies and secures the process of connecting to Wi-Fi networks. Basically, it allows to create guest networks that use 802.1x authentication and leverages Passpoint […]
This blog post is about a recent issue I had to troubleshoot. The original mission was quite simple and something I am very much used to: deploy 802.1x authentication on the Wi-Fi infrastructure using EAP-TLS (currently the best recommended option that uses certificates on both the RADIUS servers and the wireless clients). Infrastructure is fairly […]
I recently co-hosted a webinar with Cisco about Wi-Fi use cases in healthcare. This blog post provides a quick summary of the topics I discuss, along with a YouTube link to the webinar recording. The recording is in French, but you can easily enable transcription and translation on YouTube – I find it does a […]
Back in 2020, a brand-new chunk of license-free spectrum in the 6GHz band was opened up for our Wi-Fi networks to use. Unfortunately, this band is not harmonized worldwide, and only some parts of the world have access to the entire 1200 MHz of spectrum. You can check the current state of regulations here: https://www.wi-fi.org/regulations-enabling-6-ghz-wi-fi […]
Dans cette note d’information, je souhaite vous partager un sujet d’actualité qui peut avoir un impact à court terme sur les infrastructures Wi-Fi et filaires 802.1x. Qu’est-ce que Credential Guard ? Windows Defender Credential Guard est une fonctionnalité de sécurité introduit par Microsoft pour la première fois sur Windows 10 et Windows 2016 Server. Elle […]
Today I am sharing a Python script I wrote to get an access point inventory from one or more Cisco Catalyst 9800 WLAN controllers. It connects to the C9800 using the RESTCONF API, so don’t forget to first enable the API on the controller as it is disabled by default. All prerequisites and instructions are […]
In June 2022, we hosted our second Wi-Fi event at our premises in Lyon. We invited customers and partners for an entire morning of presentations on various wireless subjects. This year I had the pleasure to co-host the show with my colleagues Eloise and Bruno. Today I am sharing the recording of the event. Disclaimer: […]
