Fiz uma busca rápida por seu adaptador, com alguns resultados interessantes (mas não muito animadores).
Faz um teste por favor... executa os comandos abaixo e cola o resultado aqui. Observa também o led de funcionamento do Wi-Fi de seu aparelho, se há alguma mudança de cor ou de acendimento, ao executar os comandos.
sudo modprobe -rv ath5k
sudo rfkill block wifi
sudo rfkill unblock all
sudo modprobe -v ath5k
dmesg | tail -20
Boa tarde, Zekkerj
o led não deu sinal de vida, mesmo pressionando as teclas fn+f2 (nesta maquina ativaria o wifi)
