Enabling Fast Transition leads to connect-disconnect loop

RouterOS Wireless Networking
1

I have a Bang & Olufsen Beosound Level (WiFi speaker) that I want to connect via WiFi to my hAP ax². As soon as I enable Fast Transition on my hAP, the Beosound gets stuck in an connect-disconnect loop. I don’t know if this is something that B&O has to fix or if it’s on MikroTik’s side, so I thought I’d share. Is there anything I can do (besides disabling Fast Transition)?

I don't have any experience with B&O gear ... but quite many IoT devices have sub-par support in their WiFi stacks ... meaning that they don't like if AP supports features they don't know/expect.

Usually solution is to create a virtual AP with security settings which match client's capabilities. In your case a VAP with FT disabled.

You can make that VAP member of same IP subnet which would still allow seamless communication with controlling devices (e.g. your smart phone, using a more advanced AP).
