I have a problem with the Dune HD 4K Pro II Plus (it is also discussed in the AVS Forum), the gigabit ethernet connection does not work, when the device is turned on the green light of the rj45 led turns on (it is the gigabit) but in a few seconds it turns yellow (it is 100M). The performance per network is very poor, it does not exceed 50 MB. The Samba service also crashes, possibly due to this.
I have connected another device (to verify that it is not a problem with the router or cable and the gigabit network is correct)
thanks
