Salve Galera!

Fiz a instalação do Ubuntu 20.04 e funcionou tudo okay e normal mas a internet ficava caindo e reconectando e caindo a cada 2-5 minutos

Tentei editar o Network manager. conf pra

[device]
wifi.scan-rand-mac-address=no ( tentei trocar esse "no " pra "0" tbm n rolou)

Tentei tirar do modo power saving de 3 pra 0 e pra 2 tbm

Vi que esse chip apresenta esse problema de conexão com Mint e ubuntu desde 2014 mas não identifiquei solução como a que o pessoal tem feito em forúms

Me ajudem pls

Experimementa desabilitar encriptação no chipset. Adicione a linha
options ath9k nohwcrypt=1
No arquivo /etc/modprobe.d/ath9k.conf e reinicie. Se não funcionar desfaça.
