Hey there.
Gestern Abend habe ich das Upgrade von 22.04 auf Ubuntu 24.04.1 LTS durchgeführt. Seither geht mein WLAN nicht mehr, in den Einstellungen ist zu lesen "Kein Funknetzwerkadapter gefunden - Stellen Sie sicher, dass Ihr Funknetzwerkadapter angeschlossen und eingeschaltet ist". Davor ging es immer ohne Probleme, ich betreibe Ubuntu auf meinem Lenovo ThinkPad X1 Carbon G9 aus beruflichen Gründen im Dual-OS-Betrieb mit Windows, wo das WLAN auch weiterhin problemlos funktioniert - defekt ist der Adapter also nicht, und auch nicht ausgeschaltet. Bei dem Adapter handelt es sich um einen Intel AX201.
Ich habe es bereits mit Firmware-Update, Kernel-Update, Booten in älterer Kernel-Version versucht - Fehlanzeige. Hoffentlich kann mir hier jemand weiterhelfen. Per Kabel komme ich problemlos online (offensichtlich).
Verwendete Kernelversion (derzeit die ältere Kernelversion):
