Estou tendo alguns problemas com minha conectividade Wi-Fi. Acho que a linha mais interessante do trecho abaixo é:
Direct firmware load for ath10k/cal-pci-0000:03:00.0.bin failed with error -2.
Mas eu simplesmente não consigo descobrir como consertar isso. Eu baixei o firmware antigo e novo e sudo apt-get update/upgrade/upgrade-dist .
Meu arquivo /etc/modprobe.d tem esta aparência: options ath10k_core skip_otp=Y .
Já vi muitos outros com o mesmo problema ou semelhante, mas qualquer tentativa de seguir a solução nesses tópicos não funcionou ou piorou as coisas. Qualquer ajuda é muito apreciada. Enquanto eu corro:
sudo systemctl restart network-manager Posso acessar o wifi novamente, mas ele durará cerca de 2 minutos.

Pode estar faltando algum firmware, mas obviamente encontra firmware utilizável; caso contrário, não funcionaria de todo. Se é o firmware ideal é uma questão. Vamos tentar atualizar o firmware. Do terminal:
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161_all.deb
sudo dpkg -i linux*.deb
Reinicie e teste. Por favor, mostre-nos:
dmesg | grep ath
