Same with beta 9, getting SA query timeouts and roaming fails on a late model iPad Air and a laptop with an AX200 that worked and roamed with no problems on previous versions.The iPad started asking for the password again and it kept being rejected until I forgot the network, powered the iPad off and on and rejoined. Using a 5009 with 2x hAPAX^2. I suspect the “*) wifi-qcom - updated driver;” is the culprit. A bit late in the beta cycle to be dropping in newer drivers.
