Cannot establish Wired connection

[Cyghost]

Hello,

I am having issues with establishing a Wired Connection either on Root or Non-Root user.
I have a dual-boot system with Win7.

I cannot determine what the issue is. I am using NetworkManager. My eth0 is detected by

ip a

or

ifconfig

.
The only weird thing I notice is the Network name "Ifup(eht0)", I do not know how the Network got named like that.

Randomly, the issue resolves by itself after few

network-manager restart

, but is this common issue for R8169 chip?

Cheers,
Cyghost

Are you going to connect the Internet with DSL?
If so, you can turn on the terminal and input:
nm-connection-editor
And then you can add DSL. Just input your username and password.
