hi

da mein kleines schwarzes ca. 12-15h aktiv ist geht natürlich ab und an die Netzwerkverbindung down ( wenn sich nichts am Rechner tut usw.), jetzt musste ich feststellen das ich meine Wlankarte nicht mit meinem Router verbunden bekomme. erst mal ???

1. /etc/init.d/network-managerr restart gemacht ... ohne Ergebnis.
...dachte da hat wohl Linux ein Problem...

2. Anderes OS gestartet W-Lan funktioniert ..

4 . keine Idee mehr also Fritzbox Neustart ...... tata Wlan wieder aktiv.

Frage : kann jmd. aus der log erkennen warum die Verbindung nicht möglich wahr ?

danke

Ich denke es liegt an

DHCPv4 request timed out

dass du keine Verbindung erhältst.

Ich hatte sporadisch schon ähnliche Probleme mit einer Fritzbox 7170 und einem anderen Broadcom Chip. Ein Reset der Fritzbox hat die Verbindung dann möglich gemacht. Die eigentliche Ursache hab ich auch nie ermittelt, da das Problem vielleicht 2 mal pro Jahr auftaucht.

danke für deine Antwort, nur warum funktioniert es mit einem anderen OS ?

Genau so rätselhaft warum es nach einem Reset der Fritzbox wieder geht ...

Ich habe den Eindruck, dass die Fritzbox sich manchmal Zustände merkt und dann je nach Zustand dann anders reagiert. Linux und Windos bspw. stellen beim Aufbau einer Verbindung und beim Beziehen der IP-Adresse nicht 100% identische Anfragen. Dein anderes OS meldet sich bei der Fritzbox zB mit einem anderen Hostnamen an und verlangt eine IP Adresse und schwupps sagt die Fritzbox: Gebongt. Während für deinen Linux-Hostnamen vielleicht noch so ne halbaktive Verbindung die Box daran hindert, den Request normal zu verarbeiten.

Eine wirklich fundierte Untersuchung hab ich aber nie vorgenommen - war mir zu aufwendig da es bei mir nur selten probleme gibt.
