Sou nova no linux e estou adorando o xubuntu, o ratinho é fofo! kkk
Estou com um problema com minha rede wifi, ela não fica tão rapida como no windows. Pesquisei no google sobre solucões e nenhuma resolveu meu problema.
Problemas
- Sinal de Wifi fica bem mais baixo que no windows
- Um pouco de lentidão
Eu li sobre instalar o driver da minha placa sem ser o driver genérico e nenhuma solução que achei consegui executar com sucesso.
Segue algumas informações que podem ajudar...
