Limited ethernet speed with static IP, but ok with DHCP

Hi all,

I have a Khadas VIM 2 with default ROM installed (VIM2 Nougat 20180413).

I’m using the box as media center to run apps like Kodi and others and also as a Samba server and print server (running Android Linux Deploy).

As for it, I need a fixed IP because the network hostname I defined is not always available.

The problem is that the speed with a static IP is limited to about 40 to 50 Mbps, but it is ok when I’m using DHCP.

Is there any way to fix the problem?

Thanks all.
