Is Fast Transition supposed to work between ac and ax networks? I have a mixed setup of 4 CAPs (2 hap ax2, 1 hap ac2, 1 wap ac) which I was able to configure with wifi-qcom and wifi-qcom-ac using an RB4011 as CAPSMAN and using manual bridge config on the ac devices to make VLANs work, however it seems that fast transition is not working between ac and ax, is that expected? I have a single security configuration profile which is used by both the ac and the ax configuration profiles but I do have different profiles for ac and ax (when I tried using a single one, the ax devices were operating in ac mode).

To have it working, I had to set connect-priority (0/1) as well. That was for an ac-only setup, perhaps you will benefit from it as well...?
Do you see SA Query Timeouts in the logging?

You are awesome, connect priority did the trick for me, thank you. Toms should have mentioned this in the video.

Glad I could help you...I found the answer on this forum as well
