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

[êì]

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!
