    There is / was an issue with TSO enabled on Separate zone interfaces.

    Check this: 

    Console>  system diagnostics interface-driver-settings set <interface_name> offload tso off

    To show: Console> system diagnostics interface-driver-settings show <interface_name> offload

    • tcp-segmentation-offload: off
      tx-tcp-segmentation: off
      tx-tcp-ecn-segmentation: off
      tx-tcp6-segmentation: off

    To revert back, simply:

    Console>  system diagnostics interface-driver-settings set <interface_name> offload tso on

    There could be multiple Issues right now.

    You could start to simply check the command above.

    Next Step would be to check, if you are running V17.5 MR6.

    Another process could be, to delete and recreate the Separate Zone interface and check again.

    Next Step could be, to check, if DOS Protection strikes.

    I can confirm a DOS Protection issue, Now i disabled UDP Flood at the source and destination and  Guest WIFI go well. The problem was in the protocol ( udcp ) used in the  Wireless Separate zone interfaces.

    Thanks Marco
