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.

Antworten:
Sie können auch / var / log / syslog mit Ihrem Editor auf Fehler überprüfen.
Wenn Sie mit einem DHCP-Server (meistens dem Gateway) verbunden sind, versuchen Sie manuell, eine IP-Lease mit zu erhalten
dhclient eth1.Versuchen Sie, ein Ping an Ihr Gateway zu senden, um zu überprüfen, ob Sie mit dem Gateway verbunden sind.

Ich habe die Kanalauswahl von AUTO auf 1 umgestellt. Anscheinend trat mein Problem auf, als automatisch ein Kanal> 11 ausgewählt wurde. Tatsächlich trat mein Problem nicht ständig auf.

Scheint, dass Sie keine IP-Adresse haben.
Überprüfen Sie die IP mit

Festplattenhardwarefehler wie E / A-Fehler können dazu führen, dass das Netz ausgeht, da keine Daten vom Browser gespeichert werden.
Firewall blockiert Verkehr, sollte eine Regel haben, um TCP 25,53,80,110,443 und auch UDP 53 zuzulassen.
Wenn Sie mehrere Firewalls-Programme gleichzeitig ausführen, die ebenfalls zu einem Problem werden können, wie z. B. ufw und gufw, ist es besser, nur gufw ...
