Hallo Forum,
mein HP mit Realtek Karte findet zwar die umliegenden Netzwerke, wie er das so soll, aber irgendwie kommt keine Verbindung zustande. Heißt, ich sehe zwar mein Netzwerk, klicke drauf, gebe den korrekten Netzwerkschlüssel ein - und habe immer noch kein WLAN. Kabel immerhin funktioniert. Zwischenzeitlich hatte ich schon diese Anleitung befolgt: https://connectwww.com/how-to-solve-realtek-rtl8723be-weak-wifi-signal-problem-in-ubuntu/4625/
Hier mal die obligatorischen Pastings: uname -a
