Wie kann man häufige WLAN-Verbindungen vom MiFi-Router beheben?

Ich habe vor kurzem ein Upgrade von einem HUAWEI E153 USB-Modem auf einen mobilen E583C-WLAN-Router durchgeführt .

Das Gerät gewährt meinen anderen Geräten einwandfreien Internetzugang über WLAN, bis ich mich in meinem heutigen Büro befinde. Zwischen fünf und dreißig Minuten verlieren meine abhängigen Computer die WLAN-Verbindung.

Der Versuch, die Verbindung wiederherzustellen, schlägt fehl. Alle neuen Geräte, die versuchen, ihr WLAN-Netzwerk zu registrieren, schlagen ebenfalls fehl . Es würde sehr lange dauern, bis es sich "erholen" kann und die WLAN-Adapter die Verbindung aufheben und den Internetzugang wieder herstellen können. Ich bin gezwungen, das USB-Kabel anzuschließen, um stattdessen eine kabelgebundene Netzwerkverbindung aufrechtzuerhalten.

Mein Kollege hat ein ähnliches Mifimodell, das HUAWEI E5830, bei dem sie genau das gleiche Problem hat - außen gut, garantierte Unterbrechung im Büro.

Die erste Vermutung ist, dass es zu viele andere WLAN-Zugangspunkte im Gebäude gibt, also habe ich versucht, die Übertragungskanäle 1, 6, 11 und sogar 13 umzuschalten, aber keiner hatte bessere Ergebnisse. Die Erweiterung der Windows-Netzwerkdiagnoseprotokolle zeigt, dass es in der Gegend rund 19 Netzwerke gibt. Ich vermute also, dass die Interferenzen so groß sind, dass mein kleines Mifi-Gerät auf keinen Fall mithalten kann. Auch wenn ich die verlängerte Antenne befestige.

Im Folgenden finden Sie das Diagnoseprotokoll, in dem ich nicht richtig feststellen kann, was ich tun kann, um das Problem in diesem Bürobereich weiter zu beheben und möglicherweise zu lösen.
