I am seeing some funny behavior with stations reconnecting to an AP. Both STA and AP are running a recent hostap build, with some custom patches on top. My test case is to configure the AP for /a mode (it is on an /AC radio), and associate the station. If I then quickly restart the AP configured for /n mode, I would expect that the STA would then connect with HT enabled. However, what I notice is that it stays at /a rates. Probably this is because it did not rescan. Here is an iw event log of this: 2019-02-19 14:31:29.629 1.2: vap0000: del station 18:00:db:38:84:9c 2019-02-19 14:31:29.629 1.2: vap0000 (phy #0): stop AP # I guess maybe the AP doesn't manage to get deauth frames on the air.
