    Hi @PaoloFracas

    Thanks for your update. Or, you could adjust Egress Bandwidth to 1048576 Kbps and see if it's working for you when you are available.



    And checking whether your wan and lan port speed are 1000M/Full both?



    Thanks.

    I have tried both settings. The one with the line speed and the default one, but nothing change.

    Hi @PaoloFracas

    Could you collect the complete WAN and LAN interface packet files while you are backup files from the internet to the internal NAS server? BTW, please record the time point that file transmission is unstable.  You can provide the packet files and unstable time points to us via private message. Thanks.

    Hi PaoloFracas

    Could you upload the file to a cloud drive and share the downlink with us? Thanks.

    Zyxel Service is currently setting up a laboratory to perform tests.
    Today I would have to set up a Site to Site VPN to verify that the problem also occurs with this setup.
    I keep you updated.
    Thanks
