Ich habe hostapd als Zugriffspunkt konfiguriert, indem ich verschiedene Anleitungen mit Ubuntu 12.04 befolgt habe. Bis zu mehreren Stunden funktioniert alles einwandfrei und irgendwann akzeptiert hostapd keine neuen Verbindungen mehr.
Die Hostapd-Konfiguration lautet wie folgt:
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
Verwendung der Ausgabe von
hostapd -dd /etc/hostapd/hostapd.conf
Unter normalen Umständen werden neue Verbindungen wie folgt aufgenommen:

Durch Ausführen der folgenden Schritte wird das Problem noch einige Stunden lang behoben.
sudo service hostapd restart
Ich habe so viel wie möglich gelesen und versucht, die Sendeleistung von wlan2 von 16 dBm auf 10 dBm zu reduzieren, wie für Stabilitätsprobleme vorgeschlagen, aber das Problem bleibt bestehen.
Wenn jemand helfen könnte, wäre es sehr dankbar.
Antworten:
Führen
sudo iwconfig
Sie "Power Management" für Ihre Karte aus und deaktivieren Sie sie. Starten Sie neu und prüfen Sie, ob es jetzt in Ordnung ist. Starten Sie erneut und prüfen Sie, ob es jetzt in Ordnung ist. Wenn nicht, müssten wir es dem hinzufügenStartup Applications
.Ein Freund von mir stand vor dem gleichen Problem. Die Standard-Atheros-Treiber waren schuld. Ihr TX-Protokoll füllt sich und dies führt zu einem Authentifizierungsfehler.
Aktivieren Sie unter "Softwarequellen" / "Software und Updates" "Backports" auf der Registerkarte "Updates".
Aktualisieren Sie dann das System.
Ebenfalls:
sudo apt-get install linux-backports-modules-cw-3.6-precise-generic
Neustart & Überprüfung.
Wenn es immer noch fehlschlägt, überprüfen Sie hier: Gelöst: Ubuntu 12.04 Wifi-Treiber

@TomKat ist richtig. Der Grund, warum der Authentifizierungs-Handshake nicht durchgeführt werden kann, liegt darin, dass Ihr TX-Protokoll mit 255 Einträgen gefüllt ist. Danach starten Sie die Prozesse neu und es ist für eine Weile alles wieder gut, dann wiederholen Sie das gleiche Problem. Der Grund für die Verlangsamung der Sendeleistung, die die Zeit zwischen Ausfällen verlangsamt hat, liegt darin, dass Sie den Bereich, in dem Verbindungen möglich waren, im Wesentlichen eingeschränkt haben, sodass weniger Personen in diesem Bereich "pro Stunde" sagen. Also weniger Verbindungen = längere Zeit zwischen Ausfällen ... Oder ich könnte WAY OfF sein.
