A summary of my network: - About 30 Windows 10 users, HP Probook with Realtek WIFI adapters running the latest driver - 802.1x using NPS Radius Windows 2016 Server, Fast Reconnect enabled - 7 MR33, running the latest 26.6.1 FW - 802.11r Enabled, only 5-GHz, Bridge-mode, Width is 20MHz only - Auto Power Reduction, Channel set to Manual (no channel overlaps) My first problem is this site is about 6-hour by plane so it's a bit hard to justify to fly there. I do most of my troubleshooting on the Meraki dashboard. I will get frequent complains about wireless users losing connection when roaming. Event Logs is not showing any errors that will give me a clue on what's wrong (unless I'm not looking at it correctly). I can also confirm that the WiFi signal between APs are overlapping, specially since these APs are more or less 20 feet apart. In high-density areas, the APs are even closer. Air Marshall also looks clean. I asked someone to walk-around the office and from my pings, I can see that for 30-60 secs, they will lose their connection. There are also cases that the Relatek will quit and disable itself (the WIFI icon will disappear on the taskbar). What's interesting is we tried using a WiFi USB dongle (and disable the built-in Realtek) and this was reduced significantly. Now my questions are: 1. Is this a Realtek problem? I would like to go HP Support and report this but I'm not sure how to prove it. 2. Do you see the benefit of enabling 802.11r? How will I know if 802.11r is actually causing those Windows devices from not connecting? 3. What's the best way to troubleshoot roaming problems? Thanks for the help.
