Wired connection stopped working (Ubuntu 20.04)

vn flag

OS: Ubuntu 20.04
Hardware: Core i5-2400 CPU, 6GB DDR3 RAM

I was using the same wired connection for the past year without any issues. The LAN LED on the router lights up during boot for a few seconds. The only change I made recently was installing Qt Creator. The connection still works in Ubuntu Live CD mode so it has to be a problem with my current Ubuntu. I tried other fixes but they involved ifconfig or/and udev, which I apparently do not have installed.

There's no 'Wired' option in GNOME Settings → Network.

ip a gives the following results:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 
         link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00 
         inet 127.0.0.1/8 scope host lo 
            valid_lft forever preferred_lft forever 
         inet6 ::1/128 scope host 
            valid_lft forever preferred_lft forever

2: enp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000

What do you see in GNOME Settings → Network → Wired? What is the output of `ip a`? Please, [edit] your question and add the relevant information. Avoid screenshots!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
