Tenho um Dell Latitude 5480 pré-instalado com o Windows 10, junto com o Ubuntu 24.04 LTS.
Essa combinação funcionou bem por meses até que abri o Power Statistics e, de repente, o Wi-Fi parou de funcionar!
Então, tentei quase tudo, desde fóruns online como desligar a hibernação, desmarcar Desligar dispositivo para economizar energia, etc. no Windows e também muitas coisas no Ubuntu, mas nada funcionou!
Agora, removi os dois e instalei apenas o Fedora Workstation 40 na esperança de que isso resolvesse o problema (o que significa reinstalar o sistema operacional), mas ainda não está funcionando.
O hardware do Wi-Fi é bom e é Intel 8265. E o tethering Bluetooth, Ethernet e USB funcionam bem.
Estado atual :
- SO : Fedora Workstation 40
- Wi-Fi : Não está funcionando.
