Liebe Forenmitglieder,
ich habe mir ein ad-hoc-Netzwerk auf einem Raspberry-Pi 3B+ eingerichtet. (Siehe Foto) Anleitung siehe (https://raspberrypi.stackexchange.com/questions/94047/how-to-setup-an-unprotected-ad-hoc-ibss-network-and-if-possible-with-wpa-encry) Dieses Netzwerk wird mir nun auch auf allen Geraeten mit guter Signalstaerke angezeigt. Nun wollte ich meinen Linux-Laptop damit verbinden. Dieser verfuegt auch ueber einen IBSS-Modus. Grundsaetzlich sollte es also funktionieren.
Mein Vorgehen:
ifconfig liefert:

Ich wuerde nun zunaechst das WLAN des Computers ausschalten, den ad-hoc Modus einschalten und das WLan wieder einschalten.
sudo ifconfig wlp3s0 down && sudo iwconfig wlp3s0 mode ad-hoc channel 1 essid "IBSS-RPiNet" && sudo ifconfig wlp3s0 up
Die Ausgabe ist immer:
SIOCSIFFLAGS: Das Gerät oder die Ressource ist belegt.
iwconfig wlp3s0
liefert:
wlp3s0 IEEE 802.11 ESSID:"IBSS-RPiNet" Mode:Ad-Hoc Frequency:2.412 GHz Cell: Not-Associated Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on
Koennt ihr mir sagen, was ich genau falsch mache?
Ich wuerde mich sehr freuen, wenn ihr mir helfen koenntet, da das Erstellen des ad-hoc-Netzwerkes ein wichtiger Baustein meines Projektes darstellt.
Vielen Dank und viele Gruesse,
Salzforscher
