Wie ist das Netzwerk aufgebaut?
ein Laptop(HP550), am LAN angeschlossen, was wiederum zum Internet führ über den Anbieter T-Online. Dieser Laptop soll wiederum mit einem zweiten Laptop(HP Compaq nc4400) über Ad-Hoc verbunden werden.
Welche Systemversion wird verwendet, welche Hardware ist verbaut und wurde die Netzwerkkarte überhaupt erkannt?
