Eu instalei o Ubuntu 14.04 com atualizações via Ethernet. Agora quero usar meu Wi-Fi em casa.
Eu tenho um Netgear AC6100 (Wifi USB stick) e encontrei um driver para o stick no Github . Eu complementei e carreguei automaticamente na inicialização.
O problema é que não consigo acessar nada na rede.
# ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
--- 192.168.1.1 ping statistics ---
4 packets transmitted, 0 received, 100% packet loss, time 3023ms
Como você pode ver, o driver está funcionando (caso contrário, eu não consegui fazer um iwlist scan ) e o roteador me fornece um endereço IP correto via DHCP.
As minhas ideias para resolver o problema desapareceram. : - (
Você tem alguma ideia?
TIA
