Moin,
sowas hab ich am laufen.
Raspberry macht den AP auf, sprich wlan0. Damit ist dann Shunt, Bridge und co verbunden.
Funktioniert ohne was umzubauen.
Und über USB ist ein Wlanstick drin, der immer nach bekannten Wlan sucht und sich damit verbinden (Wlan1).
Hierfür hab ich mir ein Userflow angelegt, das ich damit Wlan Scans machen kann und dort die Verbindung aufbauen kann.
Am Besten einen Stick nehmen der von Linux so erkannt wird.

Man kann sich den Verbindungsstatus anzeigen lassen, den Stick ein und ausschalten und nach WLAN suchen.
Einen zwangs Reconnect starten, falls einen der automatische Reconnect zu lange dauert. Und es wird angezeigt ob WLAN1 erkannt wird.
Rot = Keine Hardware
Gelb = Hardware vorhanden, aber Ausgeschaltet
Grün = Aktiv
Gruß Wulle
PS. WLAN0 bekannt wlans werden nicht von WLAN1 angefasst. Sprich man muss einen Extra Scan machen und das wlan hinzufügen mit dem man sich verbinden will.
