The device that breaks your design isn't the laptop. It's the barcode scanner from 2017. Constrained clients are the ones nobody plans around. Handhelds, scanners, embedded controllers, medical carts, badge readers. Old chipsets, single spatial stream, aggressive power save, firmware that hasn't been touched in years, and roaming logic that makes decisions you would not make. Design for the phones and laptops and you get a network that tests beautifully and fails in the warehouse aisle. The practical issues are consistent. Constrained clients often hold onto an access point long past the point where they should have roamed. They may not support the fast transition mechanisms you configured. Their receive sensitivity is worse than your survey device, so your coverage map is optimistic. And their power save behavior interacts badly with settings tuned for throughput. Tom Carpenter pulled the research together in a CWNP whitepaper, and covered the practical design and troubleshooting side. Both are free.

Scanners seem to win this one most of the time. #CWNP #WirelessDesign #EnterpriseWiFi #WiFiTroubleshooting #SiteSurvey #NetworkEngineering #CWNA #CWDP #VendorNeutral #WLAN

✨lswifi v0.3.1 released!✨ lswifi isn't just on Windows anymore! Can run on macOS and Linux too: scan 2.4/5/6 GHz, --get-interfaces with link stats, and --watchevents. On Linux, should show Wi-Fi 7 MLO links. - Upgrade: python -m pip install -U lswifi - PyPI download link: pypi.org/project/lswifi/ - GH: github.com/joshschmelzle/lsw…

A new report shows 6 GHz Wi-Fi adoption has grown at an unprecedented pace, with more than 4.1 billion devices expected to ship worldwide by the end of 2026. The future of connectivity depends on preserving access to the full 6 GHz band. Read more: wififorward.org/news/press-r…

Productive discussion in London at the Wi-Fi Alliance Europe Member Meeting. We explored lessons learned from the U.S. 6 GHz experience and how other countries can share in the benefits of faster and more reliable Wi-Fi networks and services.
