Bug Description
=== SRU Justification ===
[Impact]
Realtek Wifi stops working after the driver changed from rtlwifi to
rtw88.
[Fix]
Sync rtw88 to upstream version, and use MSI on the device.
[Test]
User confirmed the backport fixes the issue.
[Regression Potential]
Low. Currently only 8822be uses rtw88.
=== Original Bug Report ===
On July 24th I upgraded to the latest linux-headers-
Today, however, when I tried to use my realtek r8822be wireless card, I discovered that it was totally unresponsive and did not work with wpa_supplicant / wpa_cli even when invoked manually from the command line (let alone with NetworkManager). When the problem occurred, I was using 19.04's latest kernel 5.0.0-21.
I then rebooted and selected kernel 5.0.0-20 from GRUB menu. "uname -a" shows that I am using the previous kernel version:
Linux pj 5.0.0-20-generic #21-Ubuntu SMP Mon Jun 24 09:32:09 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
With this kernel version as well as linux-headers-
# lsmod | grep r8
r8822be 692224 0
mac80211 806912 1 r8822be
cfg80211 671744 2 mac80211,r8822be
r8169 81920 0
Hopefully this realtek wireless regression can get fixed in the next minor kernel version. Let me know if you need any more information.
Best Regards,
Jun
