I am using the latest official firmware, im using wifi i have plenty of buffer still stutters. ill tool around with it and if i fix it ill post my solutionIf you tried with another u9h and it is the same thing you can Try a factory reset on your router (i think your router may need that).
Give more details please:
-What firmware do you use?
-Are you using wifi or ethernet ?
I advice you to use ethernet gigabit also.
If the problem remains in your u9-h do a factory reset in your minix also.
Sometimes we change many things in the router configuration and the best thing is doing a factory reset.
