I tried yet change static ip adress of tvbox. My router see this new ip adress on my device tvbox, but not going internet on tvbox still and not going also ssh through lan. I tried also command for changing 1000 to 100 full duplex through command: ethtool -s eth0 speed 100 duplex full. After was going internet through DHCP on LAN. In next restart of this tvbox i see again as 1gigabit ethertnet and again not going internet. It need fix for gigabit ethernet on this tvbox from @TheCoolest . Same as in case: Gigabit LAN driver problem After command -s eth0 speed 100 duplex full was text from lshw: *-network:1
