Locally trying to disconnect after 30 seconds. Can you try non-secure
connection and specify static IP to see if it can work?=20

I reviewed the patchset again, no obvious change if you are using a vif wit=
h
station mode only. The only one I'm not very sure is a commit related to
security CAM:
    Fixes: b837f78fbffa ("wifi: rtl8xxxu: add hw crypto support for AP mode=
")

Since each patch can be seen as individual one, could you help to bisect
the cause?=20
