I finally found out that my omega can do high speed since i'm able to stream video over my usb hub. So all is working fine !

I know this topic is quite old, but did anyone succeed in making eth0-4 work on the Omega2S in the meantime? I am just wondering, bc all documentation on the Omega2S i found so far only mentions 1 ethernet port - if it supported 5, why not say so in the docs? Of course the datasheet of the MT7688 clearly specifies 5 ethernet ports in IoT gateway mode, so why not in the Omega2S documentation?

@Diego-Acosta follow this tutorial, you also need to use --force-depends flag to install minidlna dependencies and uncomment its source.
