Larry, Sorry about all these extra replies. Shortly after I sent my last message my access point started recognizing the connection as 802.11ac with PHY Rate / Modulation Rate of 866.6 Mbps. What is somewhat misleading is the information reported by iwconfig (see bit rate below).
My bet would be that it is nitrate at which beacon or probe response is received. Regardless I would suggest using iw in this day and age. Regards, Arend

Larry, Please disregard my last message. The firmware is now installed and the rtw88 module is working with my wireless router. The next hurdle appears to be setting the speed to 802.11ac as it is currently connecting as an 802.11n client. Sincerely, David R. Bergstein On 3/1/19 9:55 PM, David R. Bergstein wrote:quoted
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 [ 267.511068] rtw_pci 0000:3d:00.0: mac power on failed [ 267.511072] rtw_pci 0000:3d:00.0: failed to power on mac [ 267.511073] rtw_pci 0000:3d:00.0: failed to setup chip efuse info [ 267.511075] rtw_pci 0000:3d:00.0: failed to setup chip information [ 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 On 3/1/19 8:46 PM, Larry Finger wrote:quoted

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. Larry
