Very Slow Transfer Speed on Raspberry Pi 4 with OMV 5

    I get this:

    How to get data from it or how to stop ?

    I booted up my old nas qnap ts-509-pro i get a constant speed 60 mb/s. from w10 client

    I transfer a movie 27 gb to the qnap.

    When i copy the same file to raspberry i get drops from 108 mb/s to 12 mb/s from w10 client

    wired/ethernet networking is best served through a powered switch rather than the 'switch' on the router.

    exactly.

    Requirements from ISPs for the WiFi routers they supply are:

    1) Hardware has to be cheap

    2) Hardware has to be cheap

    3) Hardware has to be cheap

    On your Pi from the command line iperf --version this will tell you the version running on the Pi, if it's version 2 download the zip file for version 2 for Windows, create a folder iperf2 on drive C: and extract the zip.


    Open a command prompt on Windows execute cd\ then cd iperf2


    On the Pi execute iperf -s -f K on Windows execute iperf -c <ip address of the Pi> -f K


    The output should look like this on Windows;

    Code
    iperf -c 192.168.1.204 -f K
------------------------------------------------------------

    and on the Pi like this;

    Code
    iperf -s -f K

    I booted up my old nas qnap ts-509-pro i get a constant speed 60 mb/s. from w10 client

    That's nothing to wave the flag about, I would expect 100 with slight variations during the copy process, but the fact that it's stable is a bonus

    Well the iperf output would suggest the network is OK but going back up through the thread you have this in your extra options;


    client min protocol=NT1

    ntlm auth=yes


    Why?


    Also when you added those extra options did you save and apply the changes
