Larry,

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

 
[  267.509818] rtw_pci 0000:3d:00.0: Direct firmware load for
rtw88/rtw8822b_fw.bin failed with error -2
[  267.509821] rtw_pci 0000:3d:00.0: failed to request firmware

[  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?

Sincerely,

David R. Bergstein

Larry,

Thanks for the response and detailed instructions, which allowed me to
build and install the rtw88 kernel module.  I cannot however seem to get
my system to actually use the module.  Just to recap this is an HP Omen
laptop with secure boot disabled.  Upon boot-up both the new rtw88 and
old r8822be modules are loaded.  If I unload the r8822be module the wifi
network connection gets terminated, even if I unload/reload the rtw88
module.

Is there something else I should be doing prior to invoking rtw88, e.g.,
blacklisting the old module?

Yes, r8822be must be blacklisted. Use the lsmod command to see what
modules are actually loaded. You load/unload rtw88 using the rtwpci
module.
