Hi all,
The wireless connection works perfect on my Ubuntu 20.04 Dell laptop, but the wired connection doesn't.
The wire, the router or ISP provider works correctly because I've checked on an other laptop with Windows 10 without any issues. Even called the ISP provider and we came to the conclusion that the issue is from the Ubuntu.
What is strange is that if I disconnect and connect the wired con. the ping to 8.8.8.8 is working briefly and after that is going back again:
Code:

What is also strange is why it takes the 192.168.0.107 IP when I change from the setting to 192.168.1.139?
Sometimes the ifconfig looks like this:
Code:
ifconfig enp5s0
enp5s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.139 netmask 255.255.255.0 broadcast 192.168.1.255

sudo gedit /etc/network/interfaces
with this config:

UPDATE 1: I have Peppermint as dual boot with Ubuntu and in the first the wired connection is working perfectly.
UPDATE 2: the Ubuntu 20.04 is an upgrade from 19.10.
Does anyone have any clue what I could do next?
Thanks for reading and helping me.
