Ethernet-Verbindung bricht zusammen

  • Hallo erstmal an alle,
    bin neu hier im Forum und hab auch gleich n riesen Problem.


    Ich besitze einen Raspi Model B mit installiertem Raspbian. Der Pi fungiert momentan als Access-Point, da wir auf der Arbeit nur schlechten Handyempfang haben. Soweit so gut, bis heute morgen lief auch alles einwandfrei.


    Zur Verkabelung, der Pi bekommt seine Spannung über einen USB-Hub, den ich über ein Hameg Power Supply mit 5V versorge. Als Wlandongle nutze ich den 0815 Ediamx sowieso...
    Außerdem hängt der Pi über einen Netzwerkswitch am Firmennetzwerk.


    Wie gesagt soweit lief auch alles 100%.


    Jetzt das große ABER.
    Nach einigen Minuten Laufzeit ist mir heute die Netzwerkverbindung dauernt abgebrochen. Die Ethernet-Status-LEDs leuchten anfangs kontinuierlich und ich anpingen kann ich den Pi. nach kurzer Zeit gehen dann die LEDs aus un wieder an, aber ab jetzt kann ich den Pi nicht mehr anpingen. ziehe ich das Ethernet ab und stecke ich es dann wieder ein funktioniert alles wieder für ein paar Minuten.
    Starte ich den Pi ohne Ethernetkabel und stecke es dann ein sobald der Pi gestartet ist funtkioniert es auch kurzzeitig, bis dann wieder die Verbindung abbricht und die LEDs aus und wieder an gehen.


    Leider kann ich den Pi nur Headless betreiben. Ich greife dann über VNC drauf zu.


    Hab es in der kurzen Zeit, in der die Verbindung mal da war geschafft DMESG auf zurufen. Hier die Meldungen:

    Was mich ein bischen stutzig macht sind die ständigen Meldungen "hardware isn't capable of remote wakeup", "smsc95xx 1-1.1:1.0 eth0: unregister" und "smsc95xx 1-1.1:1.0 eth0: register"


    Wäre toll wenn mal jemand drüber schauen könnte.

  • Hallo Kleen,


    zuerst einmal herzlich Willkommen in unserem Forum!


    Bei Dir hat das Mysterium zugeschlagen- und zwar in heftigster Form.


    Die Suchfunktion dieses Forum verrät Dir mehr dazu.


    Kurze Erklärung:
    Die Versorgung über USB-Hub reicht in Deinem Fall wohl nicht aus. Der WLAN-Dongle zieht zuviel Strom. Der Raspberry Pi schaltet daraufhin Ports ab (HDMI, USB, LAN, ...). Dann stellt der Raspberry Pi fest, dass er wieder Peripherie mit Strom versorgen kann. Das klappt bei USB auch recht gut - aber bei LAN gibt es leider einen Fehler im Kernel - LAN bleibt deaktiviert.


    Der Ablauf wiederholt sich. In der Log-Datei kann man das bei Dir wunderbar verfolgen:

    [ 36.186306] usb 1-1.1: USB disconnect, device number 3


    wiederholt sich mit anderen Device-Nummern aber dem gleichen Anschluss etliche Male. Du siehst: USB erholt sich, LAN niemals.


    Abhilfe:
    1. Raspberry Pi über Mikro-USB mit Strom versorgen - das Netzteil sollte beim Modell A / B 1200 mA abgeben können, beim Modell A+/B+ dürfen es auch 2000 mA sein
    2. Alles, was Du in den USB-Port steckst, betreibe über einen aktiven USB-Hub
    Dann sollte das "Mysterium" deutlich seltener stattfinden.


    Wenn Du ein wenig zum "Mysterium" recherchiert haben solltest, dann wirst Du auch ein Programm von mir gefunden haben, das das Mysterium entdeckt und behebt. Dieses liegt im Quellcode vor und kann von Dir angepasst werden.


    Beste Grüße


    Andreas

  • Erstmal vielen vielen Dank für die schnelle Antwort.


    Ich werde den Pi mal per Micro USB mit Spannung versorgen. Ich dachte es wäre außreichend den Pi über einen Hub zu versorgen, da ja auch der Hub an einem überdimensionierten Hameg hängt. Auch komisch das alles 2 Tage reibungslos funktionierte.


    Nochmals Danke
