Introduction What’s in a name/MAC – if you can use colors? Wi-Fi 6 devices are able to distinguish between frames that belong to their (associated) Basic Service Set (BSS) and Overlapping Basic Service Set (OBSS) by looking at the “color” of a frame. The term “color” is a bit misleading as it is rather a … Continue reading 11ax / Wi-Fi 6: BSS Color| WLAN by german engineering
Introduction Besides “Wi-Fi Protected Access” version 3 (WPA3) there has also been an update to open networks by the Wi-Fi Alliance in 2018 [1]. The term open networks refers to networks/SSIDs that do not require a credential (e.g. password) for a connection. This convenience is preserved with Enhanced Open. However, open previously meant that there … Continue reading Enhanced Open – Same Same But Encrypted| WLAN by german engineering
Introduction After Wi-Fi Alliance (WFA) introduced “Wi-Fi Protected Access” version 3 (WPA3) in late June of 2018 [1], vendors are pretty busy to adopt this security enhancement, which will become mandatory for WFA certifications in the future. This post introduces the changes in regards to WPA2, which is also undergoing some more robustness and consistency tests … Continue reading WPA3 – Improving your WLAN security| WLAN by german engineering
Introduction We recently got a bug entry claiming that an iPhone with iOS 10.3.2 fails to connect to a 802.1X SSID if PMF is mandatory/required, but can connect to our AP if WPA-PSK is used instead. Since we do have iPhones here, it was easy to reproduce the issue and take a look at the … Continue reading Apple client fails with mandatory PMF on 802.1X SSID| WLAN by german engineering
Scapy[1] is one mighty python tool to create, receive and manipulate various network packets and it comes with a very handy CLI as well. If you ever had the need to create specific network packets within a program, I suggest you use python together with scapy to do so. Let’s start with a short introduction … Continue reading Using Scapy to send WLAN frames| WLAN by german engineering
Introduction Like last year’s post about WLAN in 2014, you can read it here, it is time to look back what happened in the wireless space this year and give a forecast for topics of 2016. Looking Back 867 Mbps becoming the new basic speed for 5GHz APs We currently see an increasing demand for … Continue reading A look back on WLAN in 2015| WLAN by german engineering
Introduction Though some WLAN experts claim that 2.4 GHz is dead and we all should move to 5 GHz, customers still rely on 2.4 GHz due to legacy clients or even new clients with 11bgn only wi-fi adapters. Some of these customers might tell you that they want to use 40 MHz channels in 2.4 … Continue reading Go for high bandwidth in 2.4 GHz! Oh wait…| WLAN by german engineering
As I have explained in my previous blog post about the “Störerhaftung” for guest access to WLAN hotspots, offering free Wi-Fi in Germany does not come without any risks. The latest draft law tries to remove the accountability of wi-fi hotspot operators in case a wi-fi user breaches the law. If the law passes the german … Continue reading Germany’s new draft law for wi-fi hotspots| WLAN by german engineering
