Device supports TX status socket option.
Device supports HT-IBSS.
Device supports SAE with AUTHENTICATE command
Device supports low priority scan.
Device supports scan flush.
Device supports AP scan.

P2P GO supports CT window setting
Driver supports full state transitions for AP/GO clients
Driver supports a userspace MPM
Device supports active monitor (which will ACK incoming frames)
Driver/device bandwidth changes during BSS lifetime (AP/GO mode)J'ai créé le fichier de conf suivant (hostapd.conf):
#the interface used by the AP
interface=wlan_local
# "a" simply means 5GHz
hw_mode=a
# the channel to use, 0 means the AP will search for the channel with the least interferences (ACS)
channel=40
ieee80211d=1
country_code=FR
ieee80211n=1
# 802.11ac support
ieee80211ac=1
wmm_enabled=1
ssid=MYSSID
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
rsn_pairwise=CCMP
wpa_passphrase=MYPASSWORDJ'ai essayé plusieurs channels différents entre 0 et 40 mais j'ai toujours les mêmes erreurs quand je démarre le service hostapd
hostapd[1937]: wlan_local: IEEE 802.11 Configured channel (40) not found from the channel list of current mode (2) IEEE 802.11a
hostapd[1937]: wlan_local: IEEE 802.11 Hardware does not support configured channelVous avez une idée?
Merci d'avance

Re : Comment configurer le channel pour un point d'accès 5Ghz avec hostapd?
Quelques précisions:
Ma distribution : Ubuntu desktop 16.04.6 LTS
Mon WIFI : Carte PCIe Interne
D'après ce que je lis sur cette page : https://en.wikipedia.org/wiki/List_of_W … j/n/ac/ax)
Le channel 40 devrait fonctionner... Qu'en pensez vous?
Est ce que certains sont parvenus à faire fonctionner un Point d'Accès WIFI en 5 Ghz?

Bonjour,
Tu avais regardé la Doc > hostapd#configuration_d_un_point_d_acces_en_wi-fi_80211n_support_mimo ?
