Bonjour,
J'ai une machine Debian qui me sert de point d'accès wifi. Actuellement, il est en 802.11g et ça marche.
Voici hostapd.conf :
interface=wlp0s3
bridge=br0
driver=nl80211
country_code=FR
ssid=*****
hw_mode=g
channel=6
wpa=2
wpa_passphrase=*****
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
auth_algs=1
macaddr_acl=0
donne pour la partie d'intérêt :

J'ai essayé pas mal de choses mais sans succès. Notamment ici : https://doc.ubuntu-fr.org/hostapd
J'avoue humblement que je n'y connais pas grand-chose dans ce domaine. Les messages d'erreur et réactions de hostapd sont assez variés...
Si quelqu'un pouvait me donner des idées quant à une configuration qui fonctionne en HT...
