Lenovo Thinkpad T440p - interface wifi não listado [duplicado]

Question

Eu comprei recentemente um Lenovo Thinkpad T440p, onde eu instalei o Ubuntu 13.04, com as seguintes opções de rede:

• Cartão WiFi Intel Dual Band Wireless 7260AC com Bluetooth 4.0
• módulo embutido 3G / HSPA + (Ericsson N5321)

Quando executo ifconfig , obtenho apenas eth0 e lo listado.

Quando eu corro lspci :

Parece que o firmware necessário está incluído no Kernel 3.10+ se eu entendi bem o que está escrito no link e meu kernel está atualmente em 3.8 algo.

Preciso encontrar o backport correto para ativar o WiFi ou há algo mais fácil para fazer?

Obrigado antecipadamente!

Atualize para o Ubuntu 13.10 (kernel 3.11) e resolva-o. Isso confirma a lista link .
