Sou relativamente novo no Ubuntu e gosto muito dele. Recentemente instalei um Lenovo X250 e acabei de comprar no ebay um cartão Sierra Sierra AirPrime EM7345 04X6014 LTE 4G para ele e o adicionei. Acho que está tudo bem encaixado. Mas eu não consigo descobrir como fazê-lo funcionar no Ubuntu para colocá-lo em funcionamento.
