Hi

here a test of a month ago:

Microsoft Windows XP [Versione 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\Ugo Merlini>G:

G:\>iperf -w 64k -c 192.168.0.6 -r
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 64.0 KByte
------------------------------------------------------------

and here the one I made today:

Microsoft Windows XP [Versione 5.1.2600]

C:\Documents and Settings\Ugo Merlini>G:

G:\>iperf -w 64k -c 192.168.0.6 -r

Is my lan slowing down or is a false problem?

When you make tests like these, you must average over a period longer than 10 seconds and ensure that there is no other traffic on the LAN while you are making the measurement.

I suggest at least a minute for the measurement period.

And to answer your question, there is probably no problem.
