Hi Jun, dmesg shows the rtw88 driver works on your b822 wifi card.
First, you can use the following steps as work around: 1, append "blacklist rtwpci" in "/etc/modprobe.d/blacklist.conf"; 2, sudo update-initramfs -u -k 5.0.0-21-generic Because my b822 wifi card didn't reproduce the issue you got. please help debug. 1, still blacklist r8822be and remove rtw88 from blacklist; 2, add rtw88.debug_mask=0x3ff in kernel cmdline. Try to connect wifi. Then upload dmesg. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838133 Title: realtek r8822be kernel module fails after update to linux kernel- headers 5.0.0-21 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1838133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
