Dropout Hostapd

J'ai configuré hostapd en tant que point d'accès après plusieurs procédures d'utilisation d'ubuntu 12.04. Tout fonctionne bien pendant 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

Utiliser la sortie de

hostapd -dd /etc/hostapd/hostapd.conf

Dans des circonstances normales, les nouvelles connexions sont établies comme suit:

L'exécution de ce qui suit corrige le problème pendant quelques heures.

Sudo service hostapd restart

J'ai lu le plus de choses possible et j'ai essayé de réduire le facteur d'expansion de wlan2 de 16dbm à 10dbm comme suggéré pour les problèmes de stabilité, mais le problème demeure.

Si quelqu'un pouvait aider, ce serait grandement apprécié.

  1. Exécutez Sudo iwconfig et désactivez la gestion de l'alimentation de votre carte. Redémarrez et voyez si tout va bien maintenant. Redémarrez à nouveau et voyez si tout va bien maintenant. Sinon, il faudrait l'ajouter au Startup Applications.

  2. Un de mes amis a été confronté au même problème. Les pilotes Atheros par défaut devaient être blâmés. Votre journal TX se remplit et conduit à un échec d'authentification.

    Dans "Sources de logiciels"/"Logiciels et mises à jour", activez "Backports" sous l'onglet "Mises à jour".

    Puis mettez à jour le système.

    Aussi: Sudo apt-get install linux-backports-modules-cw-3.6-precise-generic

    Redémarrez et vérifiez.

  3. S'il échoue toujours, vérifiez ici: résolu: Pilotes Wifi Ubuntu 12.04

@TomKat a raison la raison pour laquelle il ne parvient pas à établir la connexion d'authentification est parce que votre journal TX est rempli avec 255 entrées. Après cela, vous redémarrez le (s) processus et tout est à nouveau en ordre, puis pendant un moment, répétez le même problème. La raison pour laquelle la réduction de la puissance de transmission a ralenti le temps entre les pannes est due au fait que vous avez essentiellement limité la plage de connexions possibles, donc moins de personnes dans cette plage "à l'heure". Donc, moins de connexions = plus de temps entre les échecs ... Ou encore, je pourrais être WAY OfF.
