[Blanarul]

You were right. Because I've restarted enough times to make it work, and them executed the commands.

But when the wireless is not working here are the results:

I really can't have this problem long time to restart 5 times in front of a customer... and hope it will work...

{code]sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
echo "options r8822be ips=N" | sudo tee /etc/modprobe.d/r8822b3.conf[/code]

Reboot, see if it is better, the only other thing that might help is to go into Network Manager settings and disable IPv6. You can also edit /etc/default/grub and make the change like the following

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ipv6.disable=1"

Then run sudo update-grub

Kind of worked until i upgraded to linux mint 19.2
Now the same problem is back. Did all the above but nothing seems to work.
I managed to get the connection agiain by removing all imputs (mouse, usb fan pad and adapter) and restarting.

It's so annoying.

What else can we do ?

The latest output when it was not working.
