Ist auch alle kein Problem, soweit es meine Daten betrifft, die werden ja regelmässig gesichert.
Aber die Hardware macht mir Probleme. Es will mir nicht gelingen meine Wlan-Karte wieder auf dem 5GHz-Band mit der Fritz-Box(6490-Cable) zu verbinden. Um alle Zweifel auszuschließen: ja das ist ein Dual-Band-Gerät und die Fritz-Box funkt auch auf beiden Bändern(als Mesh-Master).

Nutze ich nur den ersten Eintrag (bssid für das 5GHz-Band) bekomme ich keine Verbindung. Nutze ich beide Einträge, wird trotz der angegebenen priority immer mit dem 2,4GHz-Band verbunden.
Vor dem Neuaufsetzen funktionierte das nur mit dem ersten Eintrag.
Was tun?
