Ubuntu – Wifi realtek r8822be not working – ubuntu 18.04 kernel 4.15.0-20

driversnetworkingrealtek-wirelesswireless

The laptop is an Asus Vivobook S14, and it came with Endless OS linux, but I need to install ubuntu (or some other distro) because many of the applications I need are not yet available in flatpak.

It seems also that Endless does not easily allow for dual boot, so for now I'm testing kubuntu 18.04 on live booting. I have run updates, but since it's live I cannot really do fancy changes. I'm trying to avoid wiping out Endless until I'm sure the wifi will work.

I got a Plugable ethernet usb adaptor, because this laptop has no port. It worked out of the box for linux.

Secure boot is disabled.

The file rtl8822befw.bin came already in /lib/firmware/rtlwifi.

sudo lspci -v returns this about the wifi:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device b822 (rev ff) (prog-if ff)
    !!! Unknown header type 7f
    Kernel driver in use: r8822be
    Kernel modules: r8822be

Wireless info script output below.

Any directions, tips or solutions? Any help would be much appreciated.

Thank you!

The following worked for me (after rebooting)

echo "options r8822be aspm=0"  | sudo tee /etc/modprobe.d/r8822be.conf

My vivobook S14 came with Windows though.. not sure if that matters.

Kudos to the guys over on this thread: http://forum.ubuntu-fr.org/viewtopic.php?id=2026375&p=3
