Hallo Ubuntuusers,

Ich scheitere leider an einer Netzwerkbrücke, die ein WLAN-Netzwerk erstellen soll und die Verbindung dann über einen Ubuntu-Server, der per LAN Kabel mit einer Fritz Box verbunden ist, zum Internet herstellen soll. Das Schema wie ich mir das vorstelle :

client- Fritz Wlan Stick (wlx246511420f5f) - Ubuntu Server - Lan (ens32) - Fritz Box - Internet

Ich habe mich bis jetzt an den Artikel WLAN Router gehalten (https://wiki.ubuntuusers.de/WLAN_Router/), scheitere leider aber schon bei Hostapd , da das Programm nach kurzer Zeit mit der Beispielkonfiguration abbricht.

Ausgabe: sudo ifconfig -a

Wenn ich nun Hostapd im Debug Modus (sudo hostapd -dd /etc/hostapd.conf) starte erscheint folgende Ausgabe und das Programm beendet sich kurze Zeit später.

Er sagt das Gerät wäre beschäftigt. Eventuell verwaltet der NetworkManager noch das Gerät? Oder läuft schon eine Instanz von hostapd?

Scheinbar hat irgend ein Programm gestört oder eine Konfigurationsdatei war kaputt. Ich habe dasselbe einmal auf einem frisch installierten Server ausprobiert und es ging ohne Probleme 😳 . Totzdem Danke für deine Antwort

Hallo zusammen,

ich hatte exakt den selben Fehler.

Und nachdem mich das Ganze jetzt doch einige Zeit gekostet hatte, hier die Lösung für den nächsten Suchenden ☺

Wenn

interface=wlx246511420f5f

Dann auch

rsn_preauth_interfaces=wlx246511420f5f

und nicht wie in diesem Beispiel

rsn_preauth_interfaces=wlan0

Viele Grüsse ich hoffe irgend jemand ersparrt sich jetzt etwas Zeit ☺
