Debian fehlende NIC Realtek-Treiber nach Installation

[Karolinger]

Danke für die Tipps. Debian hätte ja selbst den Treiber ggf. nach Nachfrage besorgen können, nachdem beim Installationsablauf nach dem NIC-Problem der USB-Wlan Stick immer zeitweise gelaufen ist und Zugriff aufs Netz möglich war.

Jetzt tauchen die vergeblichen Anmeldeversuche vom WLan bei der Fritzbox auf, trotz Freigaben etc. wird das nichts. Bei WLan kam wohl irgendwo die Meldung "using nl80211 for Wifi device control"

Villeicht ist das noch aussagefähig, syslog wohl ähnlich wie die messages zuvor:
