  I have link-loss and packet loss problems with this NIC.

  Every 10 minutes or so it'll lose the link and it takes between 5 and 30 seconds to re-establish, impacting Applications.

  The cable(s) are short (1m) Cat7, the switch port(s) are stable with other NICs.

  Host is either MacMini M2 or Air M1, both running macOS 13.2.1

   

  There is a firmware upgrade for the NIC, but the flash utility is windows only. Really ?

  (I don't have a windows machine with TB3, so its useless.)

   

  Any options before I just return this thing ?

  @Pascal Karls The TH-S3EA uses the Aquantia AQC107S ethernet chipset and unfortunately Marvell does not offer a firmware updater for macOS. It seems like there may be a compatibility issue with the AQC107 and macOS, judging by Google search results. I would suggest the Apple Community forum to see if there is a solution.
