Comment 6 for bug 1838133

Hi Jun:

I didn't reproduce this issue on aother realtek b822 wifi card.

Could you try the following steps.

1, append "blacklist r8822be" in "/etc/modprobe.d/blacklist.conf";

2, sudo update-initramfs -u -k 5.0.0-21-generic

3, reboot to check if wifi is OK.

If it still fails, please upload dmesg.
