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

networking drivers wireless realtek-wireless

10,337

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

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!

Just to let you know, the older post askubuntu.com/questions/1045084/… is a replicate to this one - the account was changed, and there was less info there. Sorry for that. Please any one who has permission feel free to delete the old one or mark it as replicate.

This is a solution to another realtek wifi driver, but maybe can help: sovietek.wordpress.com/2018/06/09/…

I am suspicious that this: Device b822 (rev ff) (prog-if ff) !!! Unknown header type 7f suggests that the device is defective.

Defective? But it works perfectly on Endless OS, @chili555...

With the ethernet detached, restart Network Manager: sudo service network-manager restart Does NM see networks to select from? What is the result of the terminal command: dmesg | grep -e 8822 -e wlp As the result may be lengthy, paste the result here and give us the link: paste.ubuntu.com

The network-manager restart returned nothing at all. Here is the output: paste.ubuntu.com/p/52cFsxdWbC . But actually, since yesterday it started acting out on Endless also. So perhaps you were right before, @chili555

Almost every entry in your paste is error, ERR or failed. I still suspect that the hardware is failed. Sorry.
