@blocktrron @blogic Is it maybe just missing disassociation_timer here ?
I tried to send the bss_transition_request directly from the cli on ubus and found that none of my devices will switch to another ap / band if it is 0 (the default), they basically won't do anything at all, while all of them will if it is greater than 0.
In DAWN there is a default value for it so that could explain why DAWN is working better (or at all) as some users also reported here.
