can't connect to internet even by wire(could before)

Question

I've got a problem on my laptop, I had internet and wi fi all the time on it, now connections are saved but laptop isnt connecting to any internet even by using the direct wire (router is working 100%). The connection kinda just dissapeared. What to do?

Output of ifconfig -a command:

lo      link encap: local loopback. 
        Int addr:127.0.0.1 mask 255.0.0.0. 
        Inet6 add::1/128 Scope:Host. 
        UP LOOPBACK RUNNING MTU:65536 Metric: 1.
        RX packets:10756 errors:0 dropped: 0 overruns:0 frame:0. 
        TX packets:10756 errors:0 dropped: 0 overruns:0 Carrier:0. 
        Collisions 0 txquelelen:1. Rx bytes 795840 tx bytes 795840

lspci shows that Ethernet card is connected. lsmod | grep e100 shows that e100 module is loaded (See below picture):

Output of

cat /etc/modules; grep [[:alnum:]] /etc/modprobe.d/* | grep r8169:
/etc/modules: kernel modules to load at boot time.
This file contains the names of kernel modules that should be loaded
 at boot time, one per line. Lines beginning with "#" are ignored.
b43
/etc/modprobe.d/r8168-dkms.conf:# map the specific PCI IDs instead of blacklisting the whole r8169 module
/etc/modprobe.d/r8168-dkms.conf:# to blacklist the whole r8169 module
/etc/modprobe.d/r8168-dkms.conf:#blacklist r8169

, But found another problem, when I entered the site (a normal one), It says that the connection is not private and there is possibility of hackers stealing my password.

You installed Ubuntu package r8168-dkms and that changed alias ID's to keep the r8169 driver from loading. You should be able to fix by executing the following command in terminal

sudo apt-get remove r8168-dkms

Reboot

I wonder why this file was found /etc/modprobe.d/r8168-dkms.conf see http://askubuntu.com/a/804519/300665 for wifi – Jeremy31 Nov 27 '16 at 13:59
