Raspberry Pi OS • Re: Wifi broken on 64-bit image after all 2022-04 releases (since bullseye) for RPI Zero 2W

No typo. Looks like mods didn't like the whole thread and either obliterated or hid it.

See here: https://github.com/raspberrypi/bookworm ... 2245126896 and you only need the feature_disable, not the debug.

I can confirm this works by disabling the PSK offloading as mentioned there:

• made the SD-card with the latest "lite" 64-bit image (using rpi imager)
• mounted the card on my linux pc
• created a file with this command:

  Code:

  sudo sh -c "echo 'options brcmfmac feature_disable=0x2000' > <sd card location>/rootfs/etc/modprobe.d/brcmfmac.conf"

• properly eject and insert the card in your RPI Zero 2W

Fill in <sd card location> with the path to your sd card, in ubuntu it is most likely /media/username/

But off course this means there is an issue in the firmware with the PSK offloading feature and this is now being done by the CPU iso the WIFI chip.
