I am using your units embedded in a PolyPrinter 325dx. When I connect on Ethernet from a Mac or Linux machine (any browser) the web interface appears but shows not connected and none of the buttons work. When I connect from a real or virtual Windows10 browser everything works fine. The manufacturer doesn't seem to know why this happens.
Since I can connect to web server it indicates that normal Ethernet traffic is occurring.
Is this something that is really weird or should this have been something that was fixed with a firmware update?
TIA.
