Answer 1

Nós vemos isso no seu log:

 [ 2.071473] ath10k_pci 0000:03:00.0: could not fetch firmware files (-2)
 [ 2.071474] ath10k_pci 0000:03:00.0: could not probe fw (-2)

Vamos instalar o firmware. Com uma conexão de internet funcionando por ethernet, conectado ou qualquer outro meio possível, abra um terminal e faça:

cd /tmp
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.173_all.deb
sudo dpkg -i linux*.deb

Reinicie.
