    Gut, ich bin nicht der einzige, der ständig damit Probleme hat. @tkaiser auch 😉

    Ich kann heute die Fragen aller Fragen beantworten 🙂

    Damit ist leider die Frage immer noch unbeantwortet ob WLan und PCIe zusammen nutzbar ist!! Es geht!!

    Ich habe von MrFixit ein Testimage der RecalBox, benutzt das selbe Debian wie oben. Die Tage konnte man im IRC verfolgen, wie man dem Grundproblem näher kam und wohl einen Fix gebastelt hat, damit beides zusammen funktioniert. Mr.Fixit hat das in RecalBox eingebaut und ich durfte testen.

    Oben sieht man eine funktionierende WLan-Verbindung, das LAN-Kabel war entfernt. Unten sieht man die PCIe NVMe SSD, gemountet nach /mnt und Inhaltsausgabe.

    Das sollte beweisen, das der Ansatz der Lösung funktioniert. Leider kann ich nicht sagen, das es zum jetzigen Zeitpunkt stabil läuft. Ich habe einfach so Reboots, kann den Fehler aktuell aber nicht fangen. Mal sehen ob ich noch was finde.

    Aber, es ist ein Anfang!

    Mal ein Test was der Speicher so kann.
