O Ubuntu 16.04 Ethernet e Wifi não funciona após o downgrade do kernel de 4,10 para 4,4

Question

Eu uso o Acer 5750G. Eu preciso usar um software especial que está trabalhando apenas no kernel 4.4 com a rede. Então eu fiz o downgrade do kernel. Inicializar é sucesso excluir rede. Eu não tenho idéia para consertar isso. Por favor ajude.

Eu não encontrei meu driver ethernet tg3.ko e driver wireless ath9k.ko no 4.4 mas 4.10.

Aqui estão algumas informações. Espero que ajudaria. por varunendra

Resultado em 4.4

Answer 1

Estou curioso para saber o que é esse software especial. De qualquer forma, o que aconteceu claramente significa que seus drivers de wifi foram adicionados em algum lugar após o linux-4.4. Se você está realmente ansioso para rodar o 4.4, você pode descobrir qual foi o primeiro kernel com driver, e tente carregar o driver com insmod . Pode não funcionar como esperado devido a mudanças de interface entre o kernel e os drivers - é a razão pela qual o kernel do linux apesar de ter 26 anos ainda é moderno, isto é porque o kernel é frequentemente refatorado através do núcleo e drivers. Neste caso você tem que baixar fontes, manualmente portar o driver para 4.4, e construir o kernel.

Você pode usar este link para obter uma boa lista de alterações entre os kernels. Com sorte, pode ser o suficiente para descobrir onde o driver foi adicionado .
