Hi,

If it's possible I will suggest that you can use the new driver "rtw88" being
reviewed now. rtw88 is better supported by Realtek and has significant
improvement in contrast to r8822be. And also it is aim to better support
802.11ac series ICs, so it may help resolve your problem about 802.11ac
connection speeds.
Thanks!

Tony,

Thanks for your response.  Can you advise as to the availability of the
new rtw88 driver?  As it appears to be under development, I could not
locate a copy of the code for local compilation.

Sincerely,

David R. Bergstein

David,

Use the command 'git clone http://github.com/lwfinger/rtlwifi_new.git -b rtw88' 
to get a copy of the new driver for RTL8822BE and RTL8822CE in a stand-alone 
form. All that is needed is 'cd rtlwifi_new && make && sudo make install'. This 
version will build on kernels v4.4 and newer. As I have time, I will be 
backporting to kernels at least as old as 4.0.

I would appreciate your comments and bug reports.

Larry

Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

[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?

Sincerely,

David R. Bergstein

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

Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

[David R. Bergstein]

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

[  267.512817] 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

[David R. Bergstein]

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

Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

[David R. Bergstein]

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).

$ iwconfig wlo1
wlo1      IEEE 802.11  ESSID:"XXXXXXXXXX-5G" 
          Mode:Managed  Frequency:5.22 GHz  Access Point:
xx:xx:xx:xx:xx:xx  
          Bit Rate=6.5 Mb/s   Tx-Power=23 dBm  
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=70/70  Signal level=-40 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:11   Missed beacon:0

Sincerely,

David R. Bergstein

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.

It's because the initial version does not collect tx_rate report from the firmware.
So it just print out the initial value. Will be added in the next series. Thanks!

The utility iwconfig is obsolete and not exactly up to date with the latest in 
wireless. I am not an expert on iw, but I think you want 'iw dev wlo1 link'.

I am wondering about the missing firmware stage. Had you not done the 'sudo make 
install' step, or did that step fail to install the firmware?

Larry

Re: Realtek r8822be kernel module does not negotiate 802.11ac connection

[David R. Bergstein]

Larry,

I tried using iw but it gives the same reading for bit rate.  In regard
to the firmware, it was not installed via "make install" so I did it
manually.

Sincerely,

There was a typo in the Makefile. 'make install' now installs the firmware 
correctly.

As you can see, the make log does not show any errors, which is baffling
to me.  Any insight you have on resolving this issue would be appreciated.

Re: rtlwifi-new v0.6 and dkms failures

[David R. Bergstein]

Larry,

As it tuns out, I was able to create a new dkms.conf file which works on
my system. Below is  copy of the content from that file:

PACKAGE_NAME="rtlwifi-new"
PACKAGE_VERSION=0.6
MAKE="make -C $kernel_source_dir
M=$dkms_tree/$PACKAGE_NAME/$PACKAGE_VERSION/build"
CLEAN="make -C $kernel_source_dir clean"
BUILT_MODULE_NAME[0]="rtw88"
BUILT_MODULE_NAME[1]="rtwpci"
DEST_MODULE_LOCATION[0]="/updates"
DEST_MODULE_LOCATION[1]="/updates"
REMAKE_INITRD=no
AUTOINSTALL=yes

This also had the benefit of module signing by the version of dkms in
Ubuntu 19.04, so I am now also back on secure boot.

No action on your part is requested at this time.  Feel free to use the
new dkms.conf content if it is useful to you.

Regards,

David R. Bergstein
