 connection

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?

Sincerely,

David R. Bergstein
