[erledigt] Gigabit-LAN langsamer geworden
Hallo,
gleich zu meinem Netzwerk Problem.
Bis jetzt war es mir immer möglich Dateien von meinem Desktop-PC über das Netzwerk auf den Laptop zu übertragen. Mit ca. 40 Mib/s, jetzt erreiche ich nur noch ca. 15 – 20 Mib/s.
Die Übertragungsgeschwindigkeit in die entgegengesetzte Richtung ist weiterhin unverändert. (ca. 40Mib/s)
Ich hoffe mir kann jemand bei dem Problem weiterhelfen.
Hardware:
Fritzbox 6360 (Gigabit ist aktiv)
Laptop (Gigabit-LAN)
Desktop-PC (Gigabit-LAN)
Einzige Änderung die ggf. das Netzwerk. mit betreffen, war die Neuinstallation des Betriebssystems (Win7) auf dem Desktop-PC vor ca. 3 Monaten. Ob das Problem auch da schon auf trat, kann ich leider weder bestätigen noch ausschließen

Nach der Deinstallation einiger alten Programme ist meine alte Netzwerkgeschwindigkeit wieder da
