Realtek r8822be wireless card fails to work with new rtw88 kernel module

Realtek r8822be wireless card fails to work with new rtw88 kernel module

[고준]

Hello,

I recently reported a bug to Ubuntu regarding a regression in wireless
driver support for the Realtek r8822be wireless chipset. The issue
link on launchpad is:

https://bugs.launchpad.net/bugs/1838133

After Canonical developers triaged the bug they determined that the
problem lies upstream, and instructed me to send mails to the relevant
kernel module maintainers at Realtek and to the general kernel.org
mailing list.

I built kernel 5.3.0-rc1+ with the latest realtek drivers from
wireless-drivers-next but my Realtek r8822be doesn't work with
rtw88/rtwpci kernel modules.

Please let me know if there is any additional information I can
provide that would help in debugging this issue.

Best regards,
Jun

Any chance this would help you?

Somebody else was complaining about 8822be regressions that were fixed
with that.

I hope it could fix it.

And as "r8822be" was dropped, it is preferred to use "rtw88" instead.
I have received two kinds of failures that cause driver stop working.
One is the MSI interrupt should be enabled on certain platforms.
Another is the RFE type of the card, could you send more dmesg to me?

Hello,

Thanks for sharing the patch, Brian. I am seeing some progress when
building 5.3.0-rc1+ with
the wireless-drivers-next patch for the rtw88 kernel module. Before
the patch, my realtek r8822be
was not recognized at all.

After the patch, Realtek ethernet as well as wireless card r8822be are
recognized and I can see
a list of wireless access points. But for some reason, ping to my
local gateway servers (both
Ethernet and wireless) fail. Running tcpdump on my wireless and
ethernet interfaces shows
that ARP requests are showing up, but dns resolution doesn't work. I
can associate with a
wireless access point with wpa_supplicant and my ethernet port is
getting a DHCP lease from
my dhcp server, however.

And for YH~
Here is a dropbox link to debug info containing the output of dmesg,
lsmod, and journalctl -b0 zipped
up into a tarball:

Thanks for your help!
