I've been trying to set up an Access Point on an RPi CM4 with a DFRobot router board. It gets running and is visible to other devices, but when I try to connect they hang and eventually drop the connection.
In the System Log, this message is generated after each connection attempt:
Thu Jun 9 17:54:03 2022 kern.err kernel: [ 1031.470598] ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0x8a, action 0x6
which seems to be an issue with the driver for brcmfmac43456, is there something that can be done?
