Ubuntu – Possible missing firmware (Xubuntu 18.04)

18.04firmwarexubuntu

I have received this warning for a few weeks when I upgrade certain packages such as kernel or firmware.

W: Possible missing firmware /lib/firmware/rtl_nic/rtl8125a-3.fw for module r8169
W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168fp-3.fw for module r8169

I wonder if I really need to install these firmware.

Xubuntu 18.04.5
Kernel 5.4.0-47
Onboard video card

I don't know exactly, it supposedly looks like a debian bug.

Thanks!

I had this problem as well, let's run the following commands altogether.

sudo apt-get update &&
sudo apt-get -y install make gcc linux-headers-$(uname -r) build-essential git &&
git clone https://github.com/lwfinger/rtw88.git &&
cd rtw88/ &&
make &&
sudo make install &&
sudo reboot

This will restart if the process is successful. Hopefully, after the restart, you will have the wifi back.

When the kernel is changed, you need to do the following:

cd ~/rtw88
git pull
make
sudo make install

This SHOULD be done whenever you have a new kernel - no exceptions.
