J'ai configuré hostapd comme point d'accès suivant plusieurs tutoriaux utilisant ubuntu 12.04. Tout fonctionne bien jusqu'à plusieurs heures, puis à un moment donné hostapd n'accepte plus de nouvelles connexions.
La configuration de hostapd est la suivante:
ssid=PNN
wpa_passphrase=somePassphrase
interface=wlan2
bridge=br0
auth_algs=3
channel=7
driver=nl80211
hw_mode=g
logger_stdout=-1
logger_stdout_level=2
max_num_sta=255
rsn_pairwise=CCMP
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
Utilisation de la sortie
hostapd -dd /etc/hostapd/hostapd.conf
Dans des circonstances normales de nouvelles connexions sont cueillies comme suit:

L'exécution de ce qui suit résout le problème pendant quelques heures.
sudo service hostapd restart
J'ai fait autant de lecture que possible et j'ai essayé de réduire la puissance de wlan2 de 16dbm à 10dbm comme suggéré pour les problèmes de stabilité, mais le problème demeure.
Si quelqu'un pouvait l'aider serait grandement apprécié.
