Ich benutze das gleiche Netzwerk für 2 Tage und alles war normal. Obwohl ich heute als mit dem Netzwerk verbunden angezeigt werde, habe ich heute keine Internetverbindung. Wenn ich ein Ethernet-Kabel anstelle eines drahtlosen Kabels verwende, kann ich trotzdem eine Verbindung zum Internet herstellen. Außerdem können meine Freunde eine Verbindung zum drahtlosen Netzwerk herstellen und eine Internetverbindung herstellen. Ich habe seit gestern nichts aktualisiert oder installiert. Daher habe ich keine Ahnung, warum es passiert. Hier einige Informationen zu meiner Verbindung:
Ich werde mich über jede Art von Hilfe freuen.
