Hallo Adrian,
könnte man, ja. Ich würde hier aber eher vorschlagen, bei "dekonfiguration" einer Hood den Standard-AP wieder zurück auf do.not.use (bzw. das neuere äquivalent) zu setzen und diesen immer direkt nach dem Versuch ein Hoodfile zu laden wieder zu aktivieren.
Dann hat man zwar alle 5 Minuten mal ein paar Sekunden Verbindungsverlust, ist aber wohl immer noch besser als nichts.
Gruß
Fabian
