Hello World!

I'm having some problem on my New Bought Desktop. I've already installed ubuntu more than 5 times in different laptops and computers(got some little experience but still an amatuer). But this time I got a problem.

It seems my Network driver :
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 0c)
is not functioning well.

My wired connections is very Slow. My normal internet is around 4mbps - 6mbps.
but in this ubuntu 16 desktop it's only running in .20mbps - 1.40mbps.

I've already tried countless forums.
like :
downloading the newest driver,
update and install,
disabling the Ipv6

please help me reach the maximum speed of my internet.
I'm running wired connection to the router btw not via wifi.

here are some of the information that might help
