My computer does not have any WiFi adapter attached, so basically I connect my system through USB tethering from my phone. Now I want to use Ethernet connection.
Router working fine as I connected this ethernet cable with another windows machine, network working fine. In my linux system only its not connecting, ant fix would be helpful.
Distribution: Currently: OpenMandriva. Previously: openSUSE, PCLinuxOS, CentOS, among others over the years.

Are you plugging in both your ethernet cables to your router and Linux machine?
Edit:
If you are, this could cause problems.

Reason: added comment
There's many aspects to having a connection. The physical part you've covered with the cable (assuming that it's plugged in). The driver for the ethernet device likely exists and works under linux. Then you need an IP assigned and a ROUTE. DHCP can do most of this for you. Along with DNS entries to translate names to IPs (the /etc/resolv.conf file), also filled out with DHCP.
# dhclient -4 -v enp4s0f2
# ping -c 2 8.8.8.8
# ping -c 2 google.com
$ ip addr show
$ ip link show
$ ip route show
# netstat -r
# route -n
And various other ways, some deprecated, to get the deets on your setup. But throw in virtualization and docker and the methods get "different".
Your initial output states two ethernet interfaces. (being enp0s26u1u2 and enp4s0f2)
Are you sure your PC has only one ethernet card?
Can you post the model and brand of your PC?
Acer Aspire E1 series, but dont know the model name, the sticker has faded out.
I basically use USB tethering for internet connection as my laptop dont have WiFi adapter. Was it because of that another ethernet interface shows.
The -r flag explicitly releases the current lease, and once the lease has been released, the client exits. For example, open terminal and type the command:
$ sudo dhclient -r
