Hi Aaron, I have attached the output of dmesg with rr8822be blacklisted and with rtw88.debug_mask=0x3ff added to the linux commandline from GRUB.
After boot, I verified that the rtw88 driver is loaded: junbuntu@pj:~/playground$ lsmod | grep rtw rtwpci 24576 0 rtw88 413696 1 rtwpci mac80211 806912 2 rtwpci,rtw88 cfg80211 671744 2 mac80211,rtw88 But wifi is still not working. Even if I stop NetworkManager, stop wpa_supplicant and try to negotiate wifi manually (I have saved my wifi passwords and connection info from previous successful connections in a wpa_supplicant conf file) the wifi card is not coming up: junbuntu@pj:~/playground$ sudo wpa_supplicant -B -i wlp7s0 -c /etc/wpa_supplicant/local.conf Successfully initialized wpa_supplicant junbuntu@pj:~/playground$ wpa_cli -i wlp7s0 wpa_cli v2.6 Copyright (c) 2004-2016, Jouni Malinen <j...@w1.fi> and contributors This software may be distributed under the terms of the BSD license.

I didn't notice that wifi was no longer working because at work I exclusively use a wired Ethernet connection. 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-5.0.0.20, linux- headers-5.0.0-20-generic, my realtek wireless card works fine. While booted into 5.0.0-20 kernel, here are the realtek kernel modules that are loaded: # 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.
