The Windows WMM User Priority Issue - A Fix?

Image
There is a known issue with Windows clients when it comes to marking applications for QoS over wireless. In short, even if a Windows client application is configured to use DSCP 46 (EF), for example to mark voice traffic, it will translate this over the air to to use a layer 2 UP value of 5, rather than 6. This means that it will end up in the Video WMM queue rather than the Voice queue that we’d like. This has an impact on traffic prioritization over the air and could have a negative impact on our high priority traffic. This has been an issue that people have just “lived with” for quite a while, but I suspect there is a solution to this issue. I’m “putting this out there” for feedback as I can’t find any information about others using this technique. I’d like feedback from my peers to understand if the approach is viable or anyone else has used/tried it

Background Generally in my articles, I like to provide plenty of background information about a topic to encourage others to resear…

WLANPiShark: Wireless Capture With a WLANPi on Windows

One huge advantage that Apple Mac users have over owners of Windows 10 machines is the ability to perform a native 802.11 wireless packet capture direct from their built-in wireless NIC. This is extremely useful for wireless pros who want to take a quick over-the air-capture into Wireshark to analyze traffic for troubleshooting purposes. Windows users don’t have the luxury of this native wireless capture capability. In this article, we take a look at how we can use a WLANPi unit as an adapter to capture traffic over the air, straight into Wireshark on a Windows machine. With the WLANPi being powered from the USB of the laptop, this is a super convenient, portable and powerful capture method that gets Windows users a little closer to the capabilities of their cousins on Apple Macs.
