Ich habe meinen Laptop vor etwa einem Monat im Haus meiner Eltern aufgemacht und das WLAN funktionierte nicht mehr. Ich hatte immer Verbindungsprobleme mit ihrem Router, aber mein Computer hatte noch nie einen kompletten Internetausfall.
Im letzten Monat habe ich Folgendes versucht:
- Neuinstallation
iwlwifivon ISO - Upgrade von Ubuntu von 18.04 auf 20.04
- Ich habe mit so vielen Dateien herumgespielt, nachdem ich Antworten auf ähnliche Probleme erhalten hatte. Ich habe es so oft gemacht, dass ich mich nicht mehr daran erinnern kann, was ich getan habe.
Einmal war meine WLAN-Verbindung wiederhergestellt, nachdem ich dieser Antwort gefolgt bin: Kein Wi-Fi-Adapter gefunden – Ubuntu – iwlwifi. Aber als ich meine Eltern das zweite Mal besuchte, war das WLAN wieder weg und jetzt sind wir hier.
Ich glaube es hat was mit DNS zu tun, da ich es ping 8.8.8.8aber nicht kann ping google.com.
Ich möchte neu anfangen
