Hallo Ubuntuwelt

Ich habe das Problem, dass das WLAN oft im Fragezeichen-Icon hängt. Meist habe ich dann jedoch Verbindung. Sobald ich jedoch einen Netzwerkwechsel mache, selbes Icon, aber keine Verbindung mehr. Ich war lange auf 22.04, und habe mich nach einigen Artikeln und Forenbeiträgen dazu entschieden kurzfristig auf 23.10 zu wechseln bevors in die 24.04 geht. Dies, da die GNOME für mein Problem verantwortlich sei und ab GNOME 43 behoben wäre. Nun bin ich in 23.10 mit GNOME 45.2 aber das Problem besteht immernoch. Gibts Erfahrungen zur Lösung dieses Problem?

https://forum.ubuntuusers.de/topic/vor-dem-erstellen-eines-neuen-beitrags-bitte-/

Diese Ausgabe bitte posten, wenn das Problem auftritt.

Vielen Dank für die schnelle Reaktion

Ich versuche alles nötige mögliche hier anzugeben

Es spielt keine Rolle von welchem zu welchem Netzwerk, das Phänomen ist immer das selbe. In alle komme ich rein, wenn ich den Laptop komplett neu starte. An den jeweiligen Netzwerken selbst liegt es nicht.

Ich hoffe diese Infos helfen weiter

Relevant wäre vor allem der Teil zu IP-Adressen und DNS.

ok, dann weiter mit den Infos

[…] Ich habe das Problem, dass das WLAN oft im Fragezeichen-Icon hängt. Meist habe ich dann jedoch Verbindung.

Dann ist das kein Problem. Mit dem Fragezeichen wird nur angezeigt, dass keine Verbindung zu einem Testserver im Internet möglich ist. Das kann viele Ursachen haben, z.B. kompletter Ausfall der Internetverbindung (bei dir nicht), Ausfall des Testservers, Benutzung eines VPN …

[…] da die GNOME für mein Problem verantwortlich sei und ab GNOME 43 behoben wäre

GNOME ist ein Desktop und hat mit der Netzwerkkonfiguration überhaupt nichts zu tun. Er zeigt nur an, was Sache ist und reicht Benutzereingaben an das unterlagerte Netzwerkkonfigurationsprogramm des Systems weiter.

Hallo kB

Vielen Dank für deine Antwort. Das mit dem VPN liegt auf der Hand, vergesse ich aber Regelmässig wieder. Besonders wenn es um Geräteansteuerung im selben WLAN geht, passiert mit VPN natürlich nicht viel. Schade, dass die VPN Verbindung nicht explizit angezeigt wird und stattdessen eben nur das Fragezeichen dasteht.

Damit sehe ich dieses Problem als geklärt. Verbindlichsten Dank ☺

Hallo Surgakor,

Das mit der VPN Verbindung wird per Symbol angezeigt ..... kann du dies nicht vor dem Wechsel erstmal trennen bzw. deaktivieren.

Gruss Lidux

Hallo Lidux

Ich hab den Nordvpn per App laufen. Da wird leider nichts angezeigt. Über den openvpn wird es angezeigt, da hast du recht. Diesen Weg hab ich aber nicht mehr eingerichtet. Ich muss immer via Terminal mit

Sudo Nordvpn Status
Sudo Nordvpn disconnect

gehen. Wenn ich auf Geräte zugreifen will hab ichs vpn mittlerweile ausgeschaltet. Netzwerk gewechselt und dennoch trat das Phänomen auf, dass der NetworkManager gestreikt hat. Das Problem gelöst ist also nicht, aber zumindest gemildert, denn Zugriff auf Geräte im selben Netzwerk ist möglich.
