Acabei de atualizar para o Ubuntu 20.04. Meu WIFI funcionava, mas depois da atualização não consigo mais usar a placa Wifi. O computador é um laptop MSI GT75VR 7RF Titan Pro A placa Wifi é umLeitor de cartão PCI Express RTS5250 Realtek Semiconductor Co., Ltd., a julgar pela saída de lspci. Entendo pelas perguntas anteriores que o Ubuntu 20.04 pode não suportá-lo por padrão e é necessário baixar o driver, mas não consegui entender qual é o certo para mim. Você pode me ajudar a entender isso?

Magicamente começou a funcionar hoje após a reinicialização. Não me arrependo do que fiz.
