Ubuntu 14.04 + hostapd + 802.11a + iwlwifi = нет AP!

Это мой первый раз здесь, поэтому, пожалуйста, будьте добры.;)

У меня есть следующая проблема:

Я хочу установить WiFi-точку доступа 5 ГГц, потому что 2,4 ГГц слишком многолюдно.

Я использую Ubuntu 14.04 с чипом Wi-Fi Intel Corporation Wireless 3160 (версия 83). Теперь немного актуальной информации:

#lspci

Device supports RSN-IBSS.
WoWLAN support:
     * wake up on disconnect
     * wake up on magic packet
     * wake up on pattern match, up to 20 patterns of 16-128 bytes
     * can do GTK rekeying
     * wake up on GTK rekey failure
     * wake up on EAP identity request
     * wake up on 4-way handshake
     * wake up on rfkill release
HT Capability overrides:
     * MCS: ff ff ff ff ff ff ff ff ff ff
     * maximum A-MSDU length
     * supported channel width
     * short GI for 40 MHz
     * max A-MPDU length exponent
     * min MPDU start spacing
Device supports TX status socket option.
Device supports HT-IBSS.

Частота 2,4 ГГц выглядит хорошо, но "нет IBSS" в "Band 2" кажется странным.

Я уже много гуглил, но не нашел ничего подходящего. В большинстве случаев это были ошибки домена.

Я отметил интересный вывод hostapd **

Если я настрою hostapd для hw_mode=g и канала 1 f.ex. все работает отлично.

Я ценю любую помощь!

С уважением
