WLAN-Verbindung langsam / inkonsistent nach Neuinstallation Ubuntu 14.04 (Realtek RTL8188EE)

Ich habe Ubuntu 14.04 über einen Monat ohne Probleme mit den Entwickler-Builds ausgeführt. Dann habe ich am offiziellen Veröffentlichungstermin ein Upgrade durchgeführt und die Ausgabe gestartet. Ich war frustriert und habe eine Neuinstallation durchgeführt und habe immer noch das gleiche Problem.

Ich kann mich problemlos mit meinem drahtlosen Netzwerk verbinden, aber meine Verbindungsstärke und -geschwindigkeit sind sehr sporadisch. Es scheint sehr schnell wie eine Welle von sehr langsam zu normal zu schwingen. Die folgenden Ping-Ergebnisse mit meinem Router veranschaulichen dies möglicherweise.

Ping-Router, normale bis niedrige Last:

########## wireless info END ############

EDIT:

Mein Laptop ist ein Toshiba Satellite S55-A5294.

Nach dem Upgrade meines Kernels auf 3.14.1 und 3.14.2 (derzeit verwendet) ist mein Wireless jetzt manchmal verwendbar (was mich glücklich macht).

Ich verliere in etwa 70% der Fälle 0% der Pakete und in den restlichen 30% 1-100% der Pakete.

Die Wiederherstellung der Verbindung zu meinem drahtlosen Netzwerk ist die einzige Lösung, die ich bisher gefunden habe, die das Problem jedoch nicht immer behebt.

Bei Verlust von 100% der Pakete

Ich bin mir nicht sicher, ob diese Protokolle Hinweise auf die Ursache dieses Problems oder lediglich eine Benachrichtigung darüber enthalten.

Irgendwelche Ideen würden sehr geschätzt.

Dies ist ein Problem, das ich auch erlebt habe. Um dieses Problem zu lösen, müssen Sie Ihren Kernel manuell aktualisieren. Ich habe persönlich auf 3.14.1 aktualisiert.

Hier ist eine Anleitung zum manuellen Aktualisieren des Kernels: Wie kann der Kernel ohne ein Distro-Upgrade auf die neueste Hauptversion aktualisiert werden?

EDIT: Ich wusste auch nicht, wann ich das gepostet habe, aber ich habe die gleiche WLAN-Karte wie Sie, also sollte dies funktionieren. Ich kann auf keiner anderen Karte garantieren.

Ich habe mein Problem gelöst, indem ich meinen Router auf einen festen Kanal umgestellt habe (3 in meinem Fall).

Ich habe viele Dinge ausprobiert, wie das Ändern meiner Treiber, das Aktualisieren meines Kernels, aber festgestellt, dass viele drahtlose Netzwerke in meiner Reichweite sind und dies möglicherweise mit meinem in Konflikt steht, da ich dieses Problem nur in einem von drei Netzwerken hatte, die ich verwende und auf den beiden anderen hat es kein problem.

Dies war auf Ubuntu 14.04 64, Notebook Dell Vostro 5470.
