Cliffs: Não consigo fazer isso funcionar com o WPA PSK ou o WPA PEAP. O mesmo laptop (Dell Latitude E6410) com um dongle sem nome USB Wifi funciona bem conectando-se às mesmas redes. Eu percebo que esse hardware é conhecido por ter bugs com o 802.11n, então eu o desativei e obtive os mesmos resultados. Eu também tentei o truque system_certs e isso também não fez diferença alguma.
tl; dr:
iwlwifi 0000:02:00.0: Detected Intel(R) Centrino(R) Advanced-N 6200 AGN, REV=0x74

iwlwifi 0000:02:00.0: loaded firmware version 9.221.4.1 build 25532 op_mode iwldvm
Tentei todos os três blobs de firmware no kernel.org, sem mudança de comportamento.
