Following up to your last reply, I blacklisted the r8822be module,
rebooted and was unable to bring up the wireless interface via rtw88.Â
Below are some errors recorded in my system log:

[Â 267.509818] rtw_pci 0000:3d:00.0: Direct firmware load for
rtw88/rtw8822b_fw.bin failed with error -2
[Â 267.509821] rtw_pci 0000:3d:00.0: failed to request firmware
[Â 267.511068] rtw_pci 0000:3d:00.0: mac power on failed
[Â 267.511072] rtw_pci 0000:3d:00.0: failed to power on mac
[Â 267.511073] rtw_pci 0000:3d:00.0: failed to setup chip efuse info
[Â 267.511075] rtw_pci 0000:3d:00.0: failed to setup chip information
[Â 267.512817] rtw_pci: probe of 0000:3d:00.0 failed with error -114

As directed, I used the rtwpci module to perform load/unload the rtw88
module before I saw the errors above. Do I still need to install firmware?
