Atualmente estou executando o Ubuntu 15.05.
Intel Corporation Centrino Wireless-N 2230:
Eu tenho um mobo MSI com Intel Wifi:
~ % lspci | grep Centrino
04:00.0 Network controller: Intel Corporation Centrino Wireless-N 2230 (rev c4)
Mas isso não funciona no Ubuntu (funciona no Antergos Live USB). Não consigo me conectar a nenhuma rede.

Eu tentei options iwlwifi 11n_disable=0/1/8 , não faço nada.

ASUSTek Computer, Inc. USB-N13 802.11n Network Adapter:
Então eu comprei um dongle USB ASUS n-13 que anuncia suporte a Linux (US $ 40). É de 2012, então eu achei que deveria funcionar com o Ubuntu 2015.
