Durch Entfernen und erneutes Einstecken des Steckers (oder Ausschalten und erneutes Aktivieren der WLAN-Karte) wird das Problem bis zum nächsten Neustart behoben (d. h. das Netzwerk funktioniert danach bis zum Neustart unbegrenzt).
Das ist meistens ärgerlich, vor allem weil es in diesem Fall keine visuelle Ausgabe gibt. Es funktioniert einfach nicht mehr und wenn Sie versuchen, eine Online-Anfrage zu stellen (vielleicht einen Beitrag in einem Forum zu schreiben oder zu versuchen, eine neue Seite zu erreichen), funktioniert es einfach nicht mehr.
Irgendwelche Hinweise?
Heute konnte ich aktualisieren, bevor das Problem auftrat, also die syslogUSA ein

Unddiese Frageüber avahi-daemon. In diese Richtung investieren---
Antwort1
Das Problem wurde mit den normalen Updates behoben, daher ist nicht klar, wo genau das Problem lag.
Antwort2
Überprüfen Sie den Inhalt von /etc/network/interfaces. Obwohl ich mich irren könnte, klingt es für mich so, als würden Sie Ihre Netzwerke über die GUI verwalten. Ich hatte zuvor Probleme mit Konflikten zwischen meiner /etc/network/interfacesDatei und dem Ubuntu-GUI-Setup.
Wenn /etc/network/interfacesdarin Netzwerke eingerichtet sind, versuchen Sie, diese zu entfernen und nur das GUI-Setup zu verwenden. Wenn dies nicht funktioniert und die Datei nur die folgenden Zeilen enthält, versuchen Sie die folgenden Schritte.
auto lo
iface lo inet loopback
Wenn Ihre /etc/network/interfacesDatei nur diese Zeilen enthält, würde ich zunächst versuchen, alles in Ihrem Ubuntu-GUI-Netzwerk zu löschen und hier einzufügen /etc/network/interfaces:
auto eth0
iface eth0 inet dhcp
Oder um eine statische IP zu konfigurieren (für Fälle, in denen Sie keinen DHCP-Router haben):
auto eth0
iface eth0 inet static
address 192.168.1.14
gateway 192.168.1.1
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
Und ersetzen Sie es eth0durch eth1oder wlan0 usw. für eine sekundäre Ethernet- oder Wireless-Karte.
Führen Sie es dann sudo /etc/init.d/networking restartzum Testen aus und starten Sie anschließend neu, um zu sehen, ob es funktioniert hat.
PS: Ich gebe keine Garantie dafür, dass das funktioniert. Anhand der wenigen Informationen, die Sie posten können, lässt sich nur schwer sagen, wo das Problem liegt. Das ist nur das Erste, was ich versuchen würde.
